View Full Version : slavearm's mazsport turbo kit dyno
guitarjunkie28 10-27-2006, 02:35 AM i installed the mazsport turbo kit on shane's rx8 over the last few days and scott was out here and tuned it.. at least as much as he had time for anyway. we're all hoping to get back to the dyno tomorrow for some more impressive numbers.
base run was at 6psi, untuned... forgot to print that sheet, but it was something like 286whp.
he got it to 304 whp tonight @ 8psi. a/f was nice, but the timing was SO conservative, i don't think you'd ever have to worry about this thing blowing up...serious man, this was a CONSERVATIVE tune! i saw it for myself.
we're all exhausted, and i've got to get back to work. so here's a teaser sheet, and hopefully we'll have something more betterer tomorrow :)
how often do you see a turbo car keep making power past 8k? that's the shit!
california style 10-27-2006, 02:38 AM wow! good luck and keep it up!
guitarjunkie28 10-27-2006, 02:54 AM thank scott for the tuning. all i did was bolt it all on and hung out and pretended i knew what i was doing ;)
swoope 10-27-2006, 02:56 AM well this is very good news.. first blood.. keep it up!
beers :beer:
Fanman 10-27-2006, 03:00 AM thank scott for the tuning. all i did was bolt it all on and hung out and pretended i knew what i was doing ;)
Nah, I bet when he wasn't looking you were trying to take out the engine and port it right ? :mdrmed:
guitarjunkie28 10-27-2006, 03:06 AM Nah, I bet when he wasn't looking you were trying to take out the engine and port it right ? :mdrmed:
ummm.... no comment ;)
mikeschaefer 10-27-2006, 06:55 AM What the hell happened to the AFR on the second graph?! It looks like the program had a seizure. :mdrmed:
toxin440 10-27-2006, 08:06 AM wow - that's what I like to see. 300+ whp seems to be the magic number that will make everyone happy - anything else is icing on the cake. So now my question (im guessing this wont be answered till SS9) but how much did all this run you? A breakdown of total cost for the kit, the install, and cost of dyno time and cost of Scotts time would be awesome :-D
I'm no expert on turbos, so unfourtunatly I'll have to do pay someone to do ALL the work :( - but it's nice to know that the target can be achieved (300+ rwhp) and know that the engine is never going to blow up.
Fantastic work! - cant wait to see more.
Terrance26 10-27-2006, 08:16 AM I want to know how much is the upgraded turbo kit if I already have the greddy turbo kit?
rotary crazy 10-27-2006, 08:25 AM congrats! that dyno looks really good! the car most feel like a rocket
mysql101 10-27-2006, 08:33 AM I want to know how much is the upgraded turbo kit if I already have the greddy turbo kit?Far as I'm aware, it's a complete replacement. There is an option to keep the greddy intercooler (in case you don't want to remove your front bumper) and replace the rest...
I too would be interested in an actual upgrade for the greddy kit, but I haven't seen the Mazsport's turbo kit yet, so I don't know how much is interchangable.
slavearm 10-27-2006, 08:50 AM It is a complete replacement...
congrats! that dyno looks really good! the car most feel like a rocket
It is pretty quick, but I am still in grandma driving mode until Scott is done tuning.
As far as the power goes, what is scarey, is that at 6lbs with no more than 10 degrees of timing and a very very conservative fuel map, the car was making 299. Hopefully we can get more dyno time in tomorrow and see how it goes. Plenty of power left in that turbo though.
Oh... and Special thanks to:
guitarjunkie - Sleepless Wonder Mechanic, now get back to work on my car!
Scott - You are the man... sorry it got so late
The Mazsport Traveling Circus - Heheheheh my face almost cracked from the ear to ear grin didn't it?
Nick and Louie from Rotary Reliability and Racing - Thanks for the Dyno time, and access to your parts bin.
whoneedspistons 10-27-2006, 09:34 AM wow, when i saw the car perform yesterday it was nothing but impressive... there is so much more potential power even at 6 psi.... all i have to say our performance needs have been answered....
mysql.... from my understanding they do have a greddy upgrade which involves remaning the turbo... but you will have to contact mazsport mantis, and scott.....
shane, congrats on the man hopefully you wont bow that spoiler
evilmiata 10-27-2006, 10:12 AM How long did you tune last night? Exhaust? Cat? I predict torque will get higher.
maxxdamigz 10-27-2006, 10:22 AM Dyno charts are like porn for gearheads.
Raptor2k 10-27-2006, 10:29 AM Good analogy
slavearm 10-27-2006, 11:01 AM How long did you tune last night? Exhaust? Cat? I predict torque will get higher.
Not that long. I am running an RP Supercat and Greddy SP2 exhaust.
toxin440 10-27-2006, 11:11 AM Triple yum - just speculating - (and being greedy) if thats a very conservative tune, what are the chances of 330-340 horses to the wheels?
Renesis_8 10-27-2006, 11:39 AM Wow.. very impressive........

in my opinion it shouldn't be a problem at all...
XDEEDUBBX 10-27-2006, 11:48 AM congrats on the kit!
MtlRX8 10-27-2006, 12:02 PM Once the kit is in production, will it still require tuning after installation?
toxin440 10-27-2006, 12:13 PM hmmm i thought the kit was already in the early stages of production - i.e. it going on sale at (or right after) sevenstock?
mike1324a 10-27-2006, 12:15 PM Once the kit is in production, will it still require tuning after installation?
My guess is it will be like the interceptor-x, you can run it out of the box but a little fine tuning never hurt plus it might yield a little more power.
shaunv74 10-27-2006, 12:29 PM (Subscribe). Can't wait to see more!!
stickmantijuana 10-27-2006, 12:39 PM i think it's safe to say that 350rwhp is definitely well within reach.
what are your target numbers? or the highest boost level you're willing to go?
keep us posted!
slavearm 10-27-2006, 12:50 PM As high as Scott feels safe... that being said, I will probably ask that we back it off once we find that point, I want this to be as reliable as possible. If we hit 350 on crappy CA gas, i'll bust out in a session of Cumbaya (sp?).
stickmantijuana 10-27-2006, 12:55 PM when's the next tuning? :)
slavearm 10-27-2006, 01:01 PM Tonight :ylsuper:
rotary crazy 10-27-2006, 01:05 PM good luck!
Wanganrx8 10-27-2006, 01:06 PM so how's you kit setup? what kinda' turbo? placemnet? all that stuff. looks pretty good from what i can see at the dyno graph, looks like you can crank out some decent #'s when scotts all done tuning and raising boost.
RA-Eight 10-27-2006, 01:09 PM Wow, I'm glad to see this is materializing! The darkside is calling and I don't know what to do!
pdxhak 10-27-2006, 01:15 PM slavearm, I see you are in cali. It this kit CARB certified?
mazsportmantis 10-27-2006, 02:05 PM All of Mazsport's turbo kits are complete kits which inlude the Interceptor-X, the Fuel Pump upgrade and the fuel injectors to name a few key components.
The Type 1 kit has a low mounted turbo with an air to air intercooler. It is ideal for autocross or track cars where balance is a priority.
We will be completing the dyno runs today so you will see the dyno charts tonight if everything goes as planned for the day.....
colin204 10-27-2006, 02:10 PM what size turbo is it?
Red_X8 10-27-2006, 02:18 PM I thought the mazsport kit was using a GT35R turbo. Is the kit on this car the stage 1 kit? So is it safe to say that this is the lower power kit? If you call 300hp low power.
Excellent - VERY encouraging numbers and graph :)
guitarjunkie28 10-27-2006, 02:29 PM I thought the mazsport kit was using a GT35R turbo. Is the kit on this car the stage 1 kit? So is it safe to say that this is the lower power kit? If you call 300hp low power.
it's actually different than the 35r, but i don't know if i'm allowed to give details on the turbo itself... scott can release any info he wants to on the unit itself.
the 304whp @ 8psi last night was just the tip of the iceburg. he'll try to get the car up to about 350whp tonight and that'll be good enough.
there's easily 400+ whp potential from the turbo, but the 91 octane gas is our limiting factor because of the high compression. with some alky injection and/or race gas, 400 should come easy.

rotary crazy 10-27-2006, 03:58 PM there are some talented people working on this car
Cant wait to see thi scar at the show tomorrow!
Good work!
dillsrotary 10-27-2006, 04:36 PM i actually love how its just a conservative tune. yeah i like HP but having 280+ to the wheels with just 6psi is a huge selling point for me personally.
Sapphonica 10-27-2006, 06:00 PM i actually love how its just a conservative tune. yeah i like HP but having 280+ to the wheels with just 6psi is a huge selling point for me personally.
Yeah, that 6 psi is a LOT more air going into the engine than the 18g at, say, 9 psi.
Skiptomylue 10-27-2006, 06:07 PM COST.. omg im so excited.. hahah wow...i think im not going to wait for my Warrinty to expire in 3 years anymore :) NIce job!, keep the posts coming!!!!
shawn81 10-27-2006, 08:20 PM Yeah, that 6 psi is a LOT more air going into the engine than the 18g at, say, 9 psi.
that is right alot of poeple think 6 psi is not much but don't ask what turbo.... simple big turbos push more air with less Psi
toxin440 10-27-2006, 08:59 PM we have 93 octane gas here in Dallas/Fort Worth Texas so it would be interesting at the prospect of seeing 400HP -> 340-350WHP on my car in the future.
From what little ive seen this is the kit I shall be getting - 300+ rwhp that's solid and reliable as a rock - im sold!
Can't wait to see some pics, and of course more dyno charts
maxxdamigz 10-27-2006, 09:21 PM that is right alot of poeple think 6 psi is not much but don't ask what turbo.... simple big turbos push more air with less Psi
Uhh... The engine flows X volume of air at Y rpm. How much air you can fit in X volume is where boost comes in. What makes 6 psi more hp on a different turbo has to do with the temperature of the charge, quality of the tune, and some misc. things. If you stay within the high efficiency area of a turbo, running a 40/14.7 pressure ratio at whatever CFM the RE can flow at 8500 rpm or so, you'll get better power.
OfficerFarva 10-27-2006, 10:03 PM Those are some great numbers, congrats. The guys called me up and the car runs great now at 6 psi, but I'll never see that power at my 6psi.

we weren't talking about what makes the most Power, i was talking about the amount of air TURBO can push.... Big turbo pushed more Air with LESS PSI... compare to smaller turbo that has to work harder(psi) to get same amout of air pushed...
Now we will have to see if the injectors can push enough gas... and the ratio has to be (well i like it around 12.5 under boost .. yest i am running at10).... and timing Degrees just soooo much more that i am not going to get to....
RX-XSIV 10-28-2006, 12:03 AM would u be able to do an upgrade from the greddy turbo? sorry if its been covered in previous posts..i just got home from work.. its 1 AM and im dead tired and dont feel liek reading..

I'm with max .
One factor that determines how much power you can make is how much air you can jam into the engine :
What are the variables ?
Its pressure
Its Mass (affected by temp & humidity)
So - big turbo = less heat = more power at the same pressure .
am i missing something ?
OfficerFarva 10-28-2006, 12:39 AM Less heat? At least on this application, we're still talking rotary. By its inherent nature, heat is gonna be plentiful.
BaronVonBigmeat 10-28-2006, 01:32 AM He's talking about the temperature of the air being sucked in, which is moving fast enough that the main factor is turbo efficiency and whatnot, not heat soak from the engine.
slavearm 10-28-2006, 05:59 AM 335hp/255tq 12psi, blowing out the spark badly, or we would probably be seeing 350+. But being California gas, didn't want to chance anymore. I will upgrade the ignition system shortly and maybe do a pull next week.

Slavearm
So 12PSI was blowing the spark out - I'd be curious to see what you got at 10PSI - and if it was 100% rock stable.
I, like most others here, i think we would only be interested in cofigurations that are 100% stable and reliable. Will be fun to see how far you can go and still be that way.
guitarjunkie28 10-28-2006, 05:14 PM it's safe to say that this turbo kit is capable of so much more than the engine can handle on 91 octane. i'd love to talk shane into some alky injection and maybe a tank of race gas, so we can show off what not only the turbo kit, but the engine is capable of as well.
hands down, the very BEST kit available for the rx8, and one of the best, and most complete turbo kits i've ever installed on any car...and i've installed a lot.
hat's off to mazsport for making this thing!
toxin440 10-28-2006, 05:30 PM Curious - this kit supposedly comes with upgraded injectors and the fuel pump but they were still getting the spark blown out? what is involved in solving the blown-out spark problem?
And still no answer - will these kits be available for purchase? or is there a 6 month waiting list or something?

what about doing a water injection kit?
guitarjunkie28 10-28-2006, 06:13 PM i wasn't there for the second dyno session, but i'd imagine the spark being blown out would just be the stock coils.
lookingglass 10-28-2006, 08:19 PM Any chance Scott will offer the same kit sans Interceptor-X once the reflashing becomes more readily available? If I remember right the complete kit was ballparked to be in the 6k-7k range and that was before the ingition upgrades. Being able to trade in the aftermarket computer for a reflash would be a nice leg up on purchasing.
Also Scott I know you initially said no but if the response is strong enough would you reconsider CARB certification?
Cheers,
-lg
swoope 10-28-2006, 08:59 PM greddy applied carb certification almost 3yrs ago, and they're still waiting.. heck we're all still waiting. anyways, i dont think carb certification is worth the time and effort... especially considering other competitions scott's faced with now.
maybe he would take the time to apply.. never hurt to ask i guess. i guess what i'm trying to say is don't count on it.
6-7k was the rough est. for the type-1 kit. i don't think any one of us have even a slight idea about the type2's price.
what kind of safety mechanism is normally used with the water-injection kit against dry-runs? also... what's the water consumption like when you're boosting? i guess i'm looking for a very rough est.

CARB certification is becoming more and more worth it as other states besides California adopt the standard. Not to mention the entire non-racing CA populous that doesn't want to scam their smog certs.
Then again I may just be being overly hopeful. :sadwavey:
P.S.: In case people aren't reading it. Here is a link to pricing (http://www.rx8club.com/showpost.php?p=1591906) for Scott's various turbo kits.
Imidazole 10-29-2006, 05:56 AM Fix that spark issue!
nycgps 10-29-2006, 06:50 AM 10 grand for type 2.
Im just wondering, why Type 2 cost more than type 3.
maxxdamigz 10-29-2006, 06:56 AM 10 grand for type 2.
Im just wondering, why Type 2 cost more than type 3.
Type 3 might have some "you're on your own" type components or maybe it's the same boost level as type 2 with less bells and whistles.
I wanna see a parts list.....waaa!
mikeschaefer 10-29-2006, 08:08 AM That's probably why they call it Type 1, 2, 3 instead of Stage 1, 2, 3. Numbered stages would hint at increasing performance as the stage number increases. :)
mysql101 10-29-2006, 08:17 AM Type 2 looks really sweet.
The prices look inflated because he's putting all the additional add-ons into the kit.
If you took a greddy for 3.2k, added injectors, fuel pump, int-x, etc. The price would be just over 5k.
Type 3 has the air to air intercooler with the type 2 turbo placement.
That's why.
guitarjunkie28 10-29-2006, 11:12 AM i'm not sure exactly what is included in the exact kits yet, but if they come exactly as i installed shane's kit, that's a great deal!
when you think about it, a normal turbo kit for a normal car can run $3kish or so, then the ems, then the injectors, intercooler, and pretty complicated piping for the rx8 chassis, downpipe, ceramic coating, fuel pump, regulator, all the hoses and fittings, etc etc etc....
i do ground-up buildups that exceed $10-12k all the time, so i persnally think the kits are great deals. much simpler than piecing everything together yourself.
can you do it yourself and save some money? sure you can...that's true with just about everything. but the time and hastle, as well as lots and lots of tools that not everybody has... let me put it this way; if i owned an rx8, i'd buy one of these kits before fabbing up something myself. the time-to-cost ratio would work out for me.
stickmantijuana 10-29-2006, 11:59 AM w/ 93oct pump gas and all issues ironed out, how much whp do you think type-2 will put down?
i guess i'm curious to know whether it'll reach 400rwhp.
btw, where is that screw that you were talking about for bringing the clutch engagement points closer? thanks again :)
slavearm 10-29-2006, 12:04 PM There really aren't any issues. The kits lay down alot of power right out of the box. The issue is CA gas sucks. As such, we can't run as much timing, and I will be upgrading the ignition a little bit to be able to compensate with more boost and fuel. Honestly, we could probably be laying down 320ish at 6-8PSI, but I asked Scott to tune conservatively, because Oxegenated SoCal Summer Gas is really closer to 89 Octane than 91.
stickmantijuana 10-29-2006, 12:10 PM by issues, i was just specifically referring to the ignition sparks. kit looks good. i won't be getting it mostly because scott's doing a 20b swap for me, but am still curious to know what i'm missing out on! :)
congrats tho! dyno chart once everything is worked out would be very nice.
i'll put up mine once scott's done w/ my car :rofl:

320whp on 6-8psi is insane. And some through the years have claimed this engine had no potential. :rolleyes:
I tried to pull up the dyno graphs posted earlier, but it's not working very well on my pc. When is it that you're seeing full boost?

guitarjunkie28 10-29-2006, 01:12 PM There really aren't any issues. The kits lay down alot of power right out of the box. The issue is CA gas sucks. As such, we can't run as much timing...
one thing i'd like to mention from a tuning standpoint on this one is the afr's are going to be more important than the timing when dealing with lower octane fuel, at least in the higher boost ranges. i think we're fine at 6-8 psi, but by the time the boost gets into the double-digit numbers, it's a different story with a high compression motor. reason being, is there IS a point when your air/fuel charge will auto-ignite (pre-ignition) even before the spark plug is fired. this auto-ignition point is directly porportional to your compression ratio for any given air/fuel ratio. it's also inversely proportional to your air/fuel ratio for any given compression ratio. take just a sec with that one...
the higher your compression, the richer it needs to run with lower octane fuels. this part is independant of the timing.
that part takes care of the pre-ignition. now backing off on the timing is what will prevent detonation.
pre-ignition and detonation are 2 different things, but equally damaging to an engine, except that with pre-ignition, the combustion (or explosion, if you will) happens sooner in the cycle, so there's a better chance of cracking an iron at the upper dowel pin. the renesis motors have quite a bit of beef around the dowel pin compared to say an s4 motor from an fc, so there's less chance of cracking an iron, but doesn't totally eliminate the risk.
if i had to choose one, i'd probably choose detonation. there's less chance of side housing damage with it, but obviously, we'd all like to avoid both.
so for cali gas, richen it up a half a point or so in the afr's and i can't say exactly what to do with the timing because scott was doing the tuning, but i'd imagine drop at least a few degrees and go from there. i do know that the timing was extremely conservative, so these kits are making awesome power without having to tune aggressively. this is essential for reliability, especially when you're doing 6th gear top speed runs, when your egt's are going to be the highest, your motor will be the hottest, etc etc...
stickmantijuana 10-29-2006, 01:23 PM little off topic... but could you go super conservative on timing & lean it out to 15-17afr to save on gas? just curious... as long as it's not going to be too bad for the motor.
of course, that'll be just for normal city driving.
and thanks for your pm's swoope! i learn more here than in school most of the times :mdrmed:

I tried to pull up the dyno graphs posted earlier, but it's not working very well on my pc. When is it that you're seeing full boost?
Honestly, I am not quite sure... the boost is almost instantaneous at anything above 3K. Ball Bearing properly sized turbos kick asparin!

of course, that'll be just for normal city driving.
no, for the pre-ignition point i mentioned earlier. it wouldn't make any power with those afr's, even if you did manage to not blow it up, anyway.
but if you're talking about the vacuum areas, sure... lean that shit out till it stumbles, then add a touch back in. you're never going to blow an apex seal under 10+ " of hg. my rich afr comment was for the boost areas.
silverwolf 10-29-2006, 03:25 PM does anyone here have dejavu? this is just like the rx7. haha. i love it. a month ago everyone was sayin can we just get 300 whp? please? please? now in one day were like oh 300... psh (bov sound) ya we can do that.... 350.... uhuu we can get that with a little more money... anyone fore 400? maybe we can do that with tuning and octane... we uped the expectations by 100 whp in about 2 days.. hahahaha
mac11 10-29-2006, 03:26 PM Honestly, I am not quite sure... the boost is almost instantaneous at anything above 3K. Ball Bearing properly sized turbos kick asparin!
the curves on the 2 graphs posted look very linear. Like there is not going to be much of a noticable.....wow we just hit boost......effect in the middle of a gear.
guitarjunkie28 10-29-2006, 03:32 PM does anyone here have dejavu? this is just like the rx7. haha. i love it. a month ago everyone was sayin can we just get 300 whp? please? please? now in one day were like oh 300... psh (bov sound) ya we can do that.... 350.... uhuu we can get that with a little more money... anyone fore 400? maybe we can do that with tuning and octane... we uped the expectations by 100 whp in about 2 days.. hahahaha
hey, i've been saying 400+ since day 1. it's just a matter of octane.
Brettus 10-29-2006, 04:47 PM My take on it
It seems with just under 300hp you can have a car that is still a reliable daily driver that is as quick as most things out there .
Anything above that and you have to start modding every system on the car that is power sensitive turning your car into something that requires constant attention .
am I right on this ?
silverwolf 10-29-2006, 05:24 PM more or less, but dont forget then once you start upgrading your ignition components you get a more reliable system there, and you can also have a very reliable tune... its all in the tune. a reliable tuen that doesnt run it tuen rich or lean can mean constant reliable hp and that can make the 8 a beast. its when you have 15 psi and no good tune that you can come up with many problems. it take a lot of money but can be done. just watch for heat.... not to boast my thread but find my thread on cheap DIY upgrades for the 8 everything from heat to tranny stuff. its in the tech garage section. not to hard to find. or just click my name hit view public profile and tehn view alll post and there should be a recent on under the thread cheap reliability mods for the 8. just started it today i think but already gettin attention. hoping it will help all the 8 owner out there. lower temps also mean a more reliable rotoy engine as a whole.
swoope 10-29-2006, 06:53 PM one thing i'd like to mention from a tuning standpoint on this one is the afr's are going to be more important than the timing when dealing with lower octane fuel, at least in the higher boost ranges. i think we're fine at 6-8 psi, but by the time the boost gets into the double-digit numbers, it's a different story with a high compression motor. reason being, is there IS a point when your air/fuel charge will auto-ignite (pre-ignition) even before the spark plug is fired. this auto-ignition point is directly porportional to your compression ratio for any given air/fuel ratio. it's also inversely proportional to your air/fuel ratio for any given compression ratio. take just a sec with that one...
the higher your compression, the richer it needs to run with lower octane fuels. this part is independant of the timing.
that part takes care of the pre-ignition. now backing off on the timing is what will prevent detonation.
pre-ignition and detonation are 2 different things, but equally damaging to an engine, except that with pre-ignition, the combustion (or explosion, if you will) happens sooner in the cycle, so there's a better chance of cracking an iron at the upper dowel pin. the renesis motors have quite a bit of beef around the dowel pin compared to say an s4 motor from an fc, so there's less chance of cracking an iron, but doesn't totally eliminate the risk.
if i had to choose one, i'd probably choose detonation. there's less chance of side housing damage with it, but obviously, we'd all like to avoid both.
so for cali gas, richen it up a half a point or so in the afr's and i can't say exactly what to do with the timing because scott was doing the tuning, but i'd imagine drop at least a few degrees and go from there. i do know that the timing was extremely conservative, so these kits are making awesome power without having to tune aggressively. this is essential for reliability, especially when you're doing 6th gear top speed runs, when your egt's are going to be the highest, your motor will be the hottest, etc etc...
lots of very good info here.
beers :beer:
nycgps 10-29-2006, 07:05 PM I might travel to the West Coast with my 8 one day (2500 miles trip!) and they only have 91 octane there ..... If I get this I really would like some safe tune with anything as close as 300 whp as possible and be able to run it with 91 octane gas.
We have 93 Octane in NYC and NJ but just to be safe than sorry. IS it possible to have about 300whp and be able to stand 91 Octane gas ?
rotarygod 10-29-2006, 07:51 PM I'm not going to get into any more detail than to just say the Renesis engine can top 400 hp on pump gas when done properly. It's already been done.
guitarjunkie28 10-29-2006, 07:52 PM i've got 300+ on 87 octane, but not on the renesis.
silverwolf 10-29-2006, 08:04 PM STICK... kudos to you my friends. Proud of you for beating down all those (in a whiny antaginating sarcastic voice) pistons.... haha thats an 8. what would a taller gear do for you?
jeffe19007 10-29-2006, 08:36 PM Silverwolf, what are you planned changes to your ignition? I looked at your thread and saw nothing on that subject.
-Thanks-
silverwolf 10-29-2006, 09:14 PM i will!
silverwolf 10-29-2006, 09:25 PM OH OK. i spent like 5 min trying to figure out what that post meant. it refers to the thread i have on cheap reliability mods for the rx8
link!
link?
oh, here it is.
http://www.rx8club.com/showthread.php?t=102143
but no, i have nothig on that subject because there are no cheap mods. (cheap meaning a weekend pocket change project, like 10 20 bucks) HEY! if you get any ignition solutions for that price you send it here k. i dont think thatll happen soon though.
peace man.
Blake
jeffe19007 10-29-2006, 09:41 PM Ok, maybe there are no cheap mods. I was curious about what you planned to do to keep the spark from blowing out.
Anything I can get done before attempting FI is useful to me.
Renesis_8 10-29-2006, 10:23 PM u'll probably never loose to any hondas or acuras after the turbo; i never did. try popping a huge flame instead of turning on ur blinkers though. scott'll tell u how if u ask. :mdrmed:
haha, maybe a special tune built into the intx that dumps fuel when u lift at 9000rpm on 3rd gear.. hahaha!!! flame flower at the back=d

toxin440 10-30-2006, 03:38 PM when will this bastard be available for public purchase? :-D I want it now but I'm going to need about a month or two to save up the extra money and plop that much cash down at once (not to mention the install)
guitarjunkie28 10-30-2006, 03:50 PM what's the white thing in that pic? fuel pump?
not just the pump, but the whole unit! very easy install!
shane's coming over in a bit and i wanna play catch-up on all the pics i should have taken last week.

thanks
guitarjunkie28 10-30-2006, 04:41 PM hey, he showed up right as i posted that...
we swapped out the wastegate vacuum line with a copper line to prevent it from ever burning through, since things are so tight down there. i flared the ends and zip-tied the silicone hose on the ends and that'll add to the reliability.
here are some random pics... stuff is pretty hard to see because there isn't a lot of room, but at least it's something.
you can actually change the spark plugs with ease now :p:
for anyone saving these pics, i mislabeled the motor mount pics. passenger and driver side labels should be reversed. the driver side is the one by the spark plugs.
guitarjunkie28 10-30-2006, 04:43 PM and...
please excuse my "vacuum rack" there... i'm planning on making a nice one. there just aren't very many vacuum taps on the manifold, so lots of sharing going on.
turbosa22c 10-30-2006, 07:34 PM is that a to4? b? e? is the engine mount solid?
slavearm 10-30-2006, 07:43 PM is that a to4? b? e? is the engine mount solid?

Solid Engine Mounts. Yes. It is amazing how smooth the engine is. No vibration except under heavy load or if you bog it :D:
Greddyturbo1 10-30-2006, 08:47 PM Where's the turbo, is it in the same spot as the greddy turbo..
toxin440 10-30-2006, 09:21 PM from looking at the pics and guessing -- yes and no. for the type I kit, i would say "yes"
but for the type II and III kit the turbo sits up high right close to the alternator it looks like.
type II is a top mount intercooler as to type I is the bottom mount
rotarygod 10-30-2006, 09:32 PM Type 1 is a front mount air/air. Type 2 is an air/water.

mikeschaefer 10-31-2006, 07:35 AM So why do some people say that some things need to be connected to their 'own' vacuum source? I remember seeing that the Int-x should be connected that way. Is it a bad idea to just hook a rack up to the nipple behind the TB and connect everything there? (besides the wastegate signal) For my setup I was thinking EMU, boost gauge, blow off valve, and boost controller all on the same source.
maxxdamigz 10-31-2006, 07:46 AM Think of it as signal interference. You have XX vacuum at the manifold. The more tubing, intersections, and sharing going on, the higher the degradation in the signal. That's probably fine with a boost gauge. It is less desirable with your fuel control. Fuel control should be as accurate as possible making connecting it directly to the manifold desirable. It might work sharing through a junction, but it would be better to not.

that thing looks ok. let's see what shane says.
epitrochoid 10-31-2006, 01:51 PM if you could get yourself a hollow block of aluminum, you could always just tap some holes into it an screw in some threaded, barbed nipples to attach the lines to. although i dont recall the GE manifold to be that expensive.
Bart! 10-31-2006, 02:42 PM i installed the mazsport turbo kit on shane's rx8 over the last few days and scott was out here and tuned it.. at least as much as he had time for anyway. we're all hoping to get back to the dyno tomorrow for some more impressive numbers.
base run was at 6psi, untuned... forgot to print that sheet, but it was something like 286whp.
he got it to 304 whp tonight @ 8psi. a/f was nice, but the timing was SO conservative, i don't think you'd ever have to worry about this thing blowing up...serious man, this was a CONSERVATIVE tune! i saw it for myself.
we're all exhausted, and i've got to get back to work. so here's a teaser sheet, and hopefully we'll have something more betterer tomorrow :)
how often do you see a turbo car keep making power past 8k? that's the shit!
Where'd your tq go?
guitarjunkie28 10-31-2006, 03:28 PM huh?

Ordered the GE Manifold. Not very expensive even anodized. The fittings cost as much as the manifold actually.
Where'd your tq go?
199 @ 6PSI
255@12PSI (this number will go up when my HKS comes in)
epitrochoid 10-31-2006, 03:55 PM worth mentioning that those tq/psi number are about the same as the greddy kit (I hit 200 and 230 at 6 and 9 psi respectively)..
except you get to ride it all the way to 9 grand land :(

mazsportmantis 11-01-2006, 08:24 AM This is a complete kit and is currently ready for sale.
$7995 for type 1, air to air, T4 hybrid turbo, low turbo placement
$9995 for type 2, liquid to air, T4 hybrid turbo, top mounted
$8500 for type 3, air to air, T4 hybrid turbo, top mounted
and the type 4 will be coming down the road.... we joke that it is the kit your wife will never know about.....
liquid to air, T4 hybrid turbo, low mounted....can't see anything....
when Scott is back in Tampa we will dyno Type 2 and post those numbers. They took a detour to the Sema Show in Vegas.... The type 1 on Slavearm's 8 dyno'd at 335RWHP if i remember correctly. shane, could you please post that dyno chart for us?
these are all complete kits with fuel pump upgrades, primary and secondary fuel injectors and the interceptor-x included in the kit. All of the tubes are staineless steel and can be ceramic coated including the turbo and manifold for an additional charge.
thanks to everyone that helped us get that 8 dyno'd before sevenstock!!
slavearm 11-01-2006, 08:52 AM Yah sure, but remember that dyno was on crappy gas and an extremely conservative tune, and a not very sparky spark plug.
Just have to wait till I get home, because Christy has the USB key with the actual dyno files.
epitrochoid 11-01-2006, 09:10 AM What options are available to those that already have the greddy/interceptor setup?

1andonly 11-01-2006, 09:33 AM welp i know what im saveing up for! lol great job guys
slavearm 11-01-2006, 09:33 AM Talk to Christy/Mantis, I seem to recall them telling people at sevenstock, that they would subtract the cost of the parts you already owned.
They are pretty fair.
guitarjunkie28 11-01-2006, 09:39 AM Yah sure, but remember that dyno was on crappy gas and an extremely conservative tune, and a not very sparky spark plug.
AND you have a catalytic converter, which i forgot to mention before. get rid of that and it'll bump the numbers up a bit.
toxin440 11-01-2006, 09:39 AM *drools*
so what would you ESTIMATE you could get with the Type 1 with 93 octane gas (what we have here in texas), badass spark plugs, and moderatly conservative tune?
In all honest it doenst matter - because 330 to the wheels is PERFECT for me.
guitarjunkie28 11-01-2006, 09:44 AM daily driven, 330-340 shouldn't be any sort of a problem with a conservative tune. add some alky injection, and you might be able to run upper 300's whp totally reliably.
slavearm 11-01-2006, 09:48 AM I am thinking 350ish for my conservative tune at 12psi, maybe 370 or so at 14-15psi. Just keep in mind, it ships by default with a 5lb spring in the wastegate which will net you 6-8 PSI without a boost controller.
In all honesty, I think the kit is good for up to about 390-400, but you may run out of injector/turbo past that. Scott ships the setup with a nice streetable safe setup. Make sure you proceed with caution for anything beyond that. If you can, get some other int-x owners together and setup a tuning trip for Scott. It isn't that expensive, and Scott is one hell of a tuner.
slavearm 11-01-2006, 09:53 AM If I can talk RRR in Santa Ana to give me some discount dyno time, I might be ready in a week or so to do a run with 100 octane and upgraded ignition. BTW, RRR are good guys to work with. They really helped us out with the dyno, and they use a very accurate bung based WB02 instead of the typical tailpipe. Nick/Louie and team bent over backwards to help out, and kept the shop open late two nights in a row for us.
ALXVA8 11-01-2006, 10:23 AM Does the Type 3 kit have any advantages over the Type 1 kit?

i don't want to push it too hard without the alcohol injection. we're gonna be running out of gas up top, and will probably have to use the alky to compensate for the mixture, not just the detonation prevention.
slavearm 11-01-2006, 11:41 AM We can watch it, go up 500/1000rpms per pull and if the AFR starts creepin, we figured out where we have to stop. Scott was able to push I think close to 390 on 100 octane from the conversations I heard at SS9. I don't plan to run Meth long term, so I don't really want to buy a kit. If we can borrow one that would be great.
whoneedspistons 11-01-2006, 11:51 AM shane... it is a very good system to run as long as you keep track of fluid levels. you also have make sure how you tune it... if you tune it as a fuel mixture fluid level is very important but if its run just as a addititive to keep cyl temps down its not as important... it will only help you run safer... i would ask scott what mixture to run but you may think about it to help with the longevity of the motor

So Guitarjunkie will be busy next week... unless I decide to wait for the WBO2 sensor to come in MAZSPORT, so the bung can be welded at the same time. Maybe I will let creative have the car back for a couple days to finish up a couple electrical issues (with my stereo not the turbo).
model_no15 11-03-2006, 12:10 PM This thread is awesome. The videos especially are funny. There should be some sort of competition to see who can make the funniest one. Good work guys.
silverwolf 11-03-2006, 12:24 PM ferret... good man RG
im thinking that if greddy wanted to find a competative kit (ie double the hp for double the price, like mazsport only mazsport give more than double the hp of greddy) then greddy would have to put in a twin turbo set up like ones seen on the Z ( seems to be what most people compare the 8 to) or just a t3/t4 like turbo. something with fast spool up (but still, 8's redline at 9k so its not like your only going to hold it for a short time like a many piston engines) but it also must have a higher hp obviously. and of course cant top mazsport unless you include the fuel upgrades or any of the like.
Im thinking that although we love for more kits to come out.... one more KIT COMING SOON!! thread is going to kill me. to those that have their kits out i thank you (besides greddy, im with rotorygod here, it sucks) and to those that are still working on it, thank you as well because you are stayin in the game for a long time and we know youll come through for us.

evilmiata 11-03-2006, 12:31 PM Alright! My first threadjack! Scott's going to die laughing when he sees these videos.
Renesis_8 11-03-2006, 12:37 PM Tell greddy to release a sequential twin turbo with good boost from 1000rpm to 10000rpm lol. A tiny snail + a huge snail.

RealityRx8 11-06-2006, 08:03 PM Bump!
Any chance you hit another dyno?
RRx8 :)
guitarjunkie28 11-06-2006, 09:20 PM he's waiting on parts and i'm waiting on time to do the work.
TeamRX8 11-06-2006, 10:31 PM FYI, Speedsource recently discontinued their solid engine mount kit after breaking a lot of parts, and that was NA tune ....
guitarjunkie28 11-06-2006, 10:53 PM i wonder how hard they were raping on it.
TeamRX8 11-06-2006, 11:14 PM Grand Am competiton, they quit using/selling/recommending them is all I can tell you
and they specifically stated not to run solid engine mounts with rubber diff mount bushings ... it's either all solid or all rubber
dannobre 11-06-2006, 11:14 PM What kind of parts?
TeamRX8 11-06-2006, 11:16 PM What kind of parts?
if you're referring to the Speedsource mounts, they were a combination of aluminum & delrin mount using the OE brackets, I think the OE brackets were breaking and the mount chassis area cracking/breaking, even though the discussion with Sylvain was only 3 or so weeks ago it's kind of fuzzy on my brain :dunno: he said they went back to the OE drivetrain mounts
also have a pic of their new header, but I was forbidden to share it, selling for $1400 ...
slavearm 11-06-2006, 11:34 PM FYI, Speedsource recently discontinued their solid engine mount kit after breaking a lot of parts, and that was NA tune ....
Try as I might, I cannot find any reference to speedsource ever selling any solid engine mounts, nor the report that says they discontinued them due to breaking things. Got a link for me? I think it would be a very interesting read, especially considering I am making more HP than any of their 2 rotor cars ever were, and am currently utilizing a solid engine mount.
guitarjunkie28 11-07-2006, 06:35 AM your mounts aren't solid. there's a cushy piece that goes underneath the bracket.
slavearm 11-07-2006, 07:56 AM Does one rubber washer a non solid mount make?
guitarjunkie28 11-07-2006, 09:06 AM yea, actually. that's all it takes to cush it up.
mazsportmantis 11-07-2006, 12:45 PM when we sell the motor mounts they do come with grommets.....
EDITED :Freak_ani
We do utilize grommets to allow slight flexing....for each motor mount....
The grommets reduce vibration.
required mounting hardware is included.....
The motor mounts themselves are each solid, sturdy and durable......
MadDog 11-07-2006, 01:29 PM It sure looks like the bushing is left out. http://www.rx8club.com/attachment.php?attachmentid=88031
Educate me. Why would you want to do this? I would be VERY wary of making the engine block a load-bearing part of the frame. Its by far the stiffest part of the frame with a hard mount in place. Therefore, it will react a very large portion of the loads in the frame. Call me nutty, but I really would not want to start applying twisting loads and other nasty forces to my block while the rotors are twisting away at 9 grand. At first blush - isolation = good.
slavearm 11-07-2006, 01:41 PM There is a small rubber "washer/grommet type thing" there.
mazsportmantis 11-07-2006, 01:48 PM Check my post....edited for accuracy :mdrmed:
My motor mounts failed on my non turbo 8.
BTW Scott has been testing these mounts over 10k miles and in several customer cars.....
MadDog 11-07-2006, 01:53 PM Ahh... better...
MazdaManiac 11-07-2006, 01:58 PM He's adding the extra inch or so of clearance needed to get the bigger turbo in there by dropping the engine a bit and stiffening the mounting point.
Most of the twisting force will be applied radially to the housings which shouldn't distort them.
NVH will be an issue, however.
MadDog 11-07-2006, 02:19 PM Yeah, I knew that Scott's mod was to make room, but TeamRX8 mentioned that Speedsource had solid mounts on a NA car.
silverwolf 11-08-2006, 09:00 AM so umm... how are those ignition component upgrades coming? we gonna see another dyno soon? i hope so, i wanna see 400 whp.
slavearm 11-08-2006, 10:17 AM Ignition upgrades are still not here yet =( HKS was really backed up following SEMA. Supposedly they shipped yesterday though.
silverwolf 11-08-2006, 10:32 AM well thats good. i thought they were shipped earlier.... must have misread. so do you think that you can get 400 whp on your 8.. and what does it feel like right now? i cant imagine it being that quick.
slavearm 11-08-2006, 10:55 AM I think 400 might be a reach without larger injectors, or alky injection. I will have good fuel for my next run though. 380ish is definately a possibility.
How does it feel? Well... it seems like everyone else is in slow motion when I get on it. The cool thing is, it never stops pulling... the power just keeps increasing with the RPMs.
My neighbor who owns the hopped up and now broken motor TII says "$#!t that is fast."
My brother in law said, "Dayaaaaaam... lets go find some STIs."
Guitarjunkiue28 said, "Wow that feels pretty good"
My cube mate with a hopped up 68 Vette said, "Holy $#!t that's only 1.3L?!?!"
My wife said, "Ok... your car is scarey now (as she grabs the door handle with a death grip)... we are taking my car"
My Kid said, "Zoom zoom dad" (Yes, he really did say that... he also calls GuitarJunkie "Different Dave")
whoneedspistons 11-08-2006, 11:36 AM lol.. different dave... you guys were great to hang out with in cali
Wanganrx8 11-08-2006, 03:23 PM hehe I'm picking my car up from mazsport this firday, just got a new fuel system, I think i'll leave the whole turbo thing alone... well untill i save up for the stage 3 kit, and hks dli. which should be around december, i have some gauges, wb o2, suspension and other stuff to get first, but that last post slavearm just did is inspiring me to maybe jump the gun and get the kit sooner. Damn you, mazsport for building a badass turbo kit!!!
silverwolf 11-08-2006, 03:50 PM incredible. i cant image.
but the hooking issue must be a terrible situation. have you floored it in first or second gear?
slavearm 11-08-2006, 04:13 PM Its fine if you don't drop the clutch. The power really starts coming on around 3500-3800rpms, but I am running extremely stickly 180Treadlife 245 width tires. You gotta watch it though... because 1-3rd you can break loose. Look at the dynos earlier in the thread to see what I am talking about.
silverwolf 11-08-2006, 09:29 PM ya i saw.... really a beast.
Red_X8 11-09-2006, 12:09 AM Ah shit, I'm gonna play too, http://www.grapheine.com/bombaytv/play_uk.php?id=1750086
guitarjunkie28 11-09-2006, 08:29 PM that was funny.
i got the clutch today :) let's see what happens next week.
Razz1 11-09-2006, 11:31 PM Which clutch dis ya get?
guitarjunkie28 11-10-2006, 04:53 AM dunno, haven't opened it yet.
my fd got alky injection today... does 0-100 in about 9 1/2 seconds. i'm traction-limited. :(
morkusyambo 11-12-2006, 08:08 AM dunno, haven't opened it yet.
my fd got alky injection today... does 0-100 in about 9 1/2 seconds. i'm traction-limited. :(
Are you using the same system rotary god talks about in his 500hp on pump gas thread??
guitarjunkie28 11-12-2006, 05:16 PM na, i've had an aquamist for years.
i don't need programmable injection for what i use it for. right now, it's not to cheat on horsepower, i tuned the car right where i wanted it, then i piss in about 10% extra alky solely as a safety margin. i can go from 0 to redline in 5th gear and my egt's will never get above 720c post turbo
BigOLundh 11-14-2006, 09:16 PM WTF??? all these bollywood clips and nobody even sent me a PM for the thread. SHEESH PEOPLE!!
I'm going to be back with the bollywood thunder later tonight. Oh wait, i still have a greddy turbo and am sticking by it :(
-hS
guitarjunkie28 11-20-2006, 08:29 PM i've been really busy the last week, but we're gonna do a bit more work on the car soon. hopefully we'll get the alky on and get some more impressive dynos in the weeks to come. everyone's afraid of 91 octane :p:
lookingglass 11-22-2006, 10:46 PM Slavearm, now that you've had a chance to drive with this kit for a while what is the fuel consumption like?
Cheers,
lg
slavearm 11-22-2006, 11:21 PM If I could stay off the throttle, it probably wouldn't be too bad... as is, I am getting about 14-15mpg. I got about 18 when I was first breaking it in and taking it real easy. Ask guitarjunkie how I drive though =)
BlueRenesis82 11-23-2006, 08:10 AM If I could stay off the throttle, it probably wouldn't be too bad... as is, I am getting about 14-15mpg. I got about 18 when I was first breaking it in and taking it real easy. Ask guitarjunkie how I drive though =)
what kind of mileage were you seeing before the snail?
slavearm 11-23-2006, 09:03 AM 16-19 before the snail.
BlueRenesis82 11-23-2006, 09:23 AM so not a real tremendous difference?
slavearm 11-23-2006, 09:46 AM I get about 160miles to a tank now... I used to get ~200
guitarjunkie28 11-23-2006, 11:28 AM my fd does better on gas than the 8, and it's over 400whp :D
Brettus 11-23-2006, 11:34 AM lot lighter though isn't it ?
What will a fd with that much hp do the 1/4 mile in ?
dtorre 11-23-2006, 11:37 AM Fd will run mid 10's -mid 11's with 400whp
Brettus 11-23-2006, 11:43 AM hmmmm - no wonder I got smoked so badly the other night :(
wonder if anyone will ever get an 8 to go that quick .
MazdaManiac 11-23-2006, 11:53 AM Fd will run mid 10's -mid 11's with 400whpUh, no.
First of all, the HP has little to do with the ET. Trap speed is what results from power. ET is a function of power band, gearing and traction.
Second, unless that FD only weighs 1800 LBS, it is not going into the mid 10's with only 400 HP easily.
It will probably trap above 120 MPH, though.
Brettus 11-23-2006, 01:04 PM MM - do you think a JDM spec 8 with a 3rd gear that goes to 100 MPH would have an advantage in the 1/4 mile over a US spec 8 that goes to 90 ?
:stickpoke
guitarjunkie28 11-23-2006, 01:16 PM lot lighter though isn't it ?
What will a fd with that much hp do the 1/4 mile in ?
actually, no. maybe 100lbs ligher at most. my fd is full-weight. 2950 with me in it and an almost empty tank of gas. so it's 3k-3050 ish pounds with me + full tank of gas.
MazdaManiac 11-23-2006, 01:39 PM MM - do you think a JDM spec 8 with a 3rd gear that goes to 100 MPH would have an advantage in the 1/4 mile over a US spec 8 that goes to 90 ?
:stickpokeNo. It would be the other way around. Deeper gearing means more torque multiplication.
actually, no. maybe 100lbs ligher at most. my fd is full-weight. 2950 with me in it and an almost empty tank of gas. so it's 3k-3050 ish pounds with me + full tank of gas.
So, mid 11's around 115 if you really pound it.
Brettus 11-23-2006, 01:44 PM [QUOTE=MazdaManiac]No. It would be the other way around. Deeper gearing means more torque multiplication.[QUOTE]
you don't think 1 less gear change would make up for that ?
Brettus 11-23-2006, 01:49 PM actually, no. maybe 100lbs ligher at most. my fd is full-weight. 2950 with me in it and an almost empty tank of gas. so it's 3k-3050 ish pounds with me + full tank of gas.
so a slightly modded (200-210 whp) RX8 should be able to match it with a stock FD ?
Renesis_8 11-23-2006, 02:03 PM I dont think so, the FD still has more torque.

tiltmode43 11-23-2006, 02:11 PM so a slightly modded (200-210 whp) RX8 should be able to match it with a stock FD ?
Even if that were the truth, good luck finding a stock fd...
guitarjunkie28 11-23-2006, 03:10 PM So, mid 11's around 115 if you really pound it.
that sounds about right, but i haven't taken it to the drag strip yet. this car is a supra killer at high speeds (150+)
MazdaManiac 11-23-2006, 03:13 PM No. It would be the other way around. Deeper gearing means more torque multiplication.
you don't think 1 less gear change would make up for that ?No. By the time you are moving to 4th, the difference would already be close to a car length. You would have to really ruin the shift to loose at that point.
(All other things being equal, of course.)
MazsportScott 12-07-2006, 05:53 PM Slavearm, Now that you have had some seat time in your turbo'd 8, what are your impressions of it as a daily driver? Scott
slavearm 12-07-2006, 09:33 PM It's fine. It is alot more fun actually. The gas milage is worse, and it is definately louder, but quieter than the car with a midpipe and exhaust. Once you get all the tuning done, its just about OEM. Except for it being a bit louder than stock... it really drives like the car came with a turbo.
I let my brother-in-law drive it, and he is currently saving up for a Type-I or Type-III. He couldn't believe how well it drove... or how fast it was...
Anyways, can't say I regret it one bit, even my wife has come around and thinks it is cool now.... took her awhile to get used to the cool turbo sound.
Clavius 12-07-2006, 09:49 PM I get about 160miles to a tank now... I used to get ~200
Slavearm if it will help ya feel better about mileage I get around 130-140 miles per tank and I'm NA and a A/T :(
Nice to see your not having any problems with the kit been serveral pages since I looked at this thread now the long journey to save up money /sigh.
slavearm 12-07-2006, 09:57 PM Oh... and don't anyone go and get the impression I baby it. To use a Guitarjunkie term, "I rape on it daily"
llzjayarzll 12-07-2006, 10:05 PM what the hell is in ur ride clavius?
Clavius 12-07-2006, 10:13 PM ^No clue gonna take Brettus's advice and hopefully weather permitting (chance of snow this weekend UGH!) gonna check out my MAF a few have said it could be the cause but 'eh.. my service dept says "well most rx-8's get that kinda milage"...
Its that or I have a deadbody in my enginebay 'cause I cleaned my trunk out last week.
So yeah Slavearm your still in the good range of milage buddy! :rock:
Umbra 12-08-2006, 09:56 AM Do you have a constant CEL with that setup?
slavearm 12-08-2006, 10:06 AM Do you have a constant CEL with that setup?
According to the stock computer I am too rich, and soemthing in the intake manifold is stuck open. The intake manifold is an easy fix that I just haven't got around to yet. The too rich... well the stock computer is just full of crap on that one and I eagerly await someone to figure out a means to convince the stock computer that it is not too rich.
Slavearm
mike1324a 12-08-2006, 11:51 AM You will have a constant CEL with the interceptor-x and any application, N/A or turbo.
MadDog 12-08-2006, 12:43 PM I hope its the VDI that's stuck open and not the APV. The first is easy, the second requires removal of the engine.
guitarjunkie28 12-08-2006, 07:22 PM apv?
is that the aux. port actuator? aka, 5th and 6th ports?
swoope 12-09-2006, 01:53 AM apv?
is that the aux. port actuator? aka, 5th and 6th ports?
yes,
if you need pics of what is happening in those ports let me know...
beers :beer:
guitarjunkie28 12-09-2006, 03:37 AM well i know we've got a code for that, but that's because the stepper is gone and they're blocked open.
but let's see some pics anyway--i like learning new stuff.
what's the main problem people are encountering with them?
