View Full Version : Anyone know of 200+whp STOCK RX8s? I saw one today...
206hp...yup. Saw it...it's on film
Today a few NW RX8 ppl gathered for a dyno. MOST RX8s there spun about 185 at the wheels...very consistantly within a couple-few HP of one-another.
Until the Silver w/ Red/black leather went...198whp on one run...he hit 206 on another...His A/F ratios were in the mid 12:1 range; compared to my cars A/F's were were a solid point richer.
I'm not going to steal his thunder furhter, so I'll let him post up about it...
Thanks to all who posted up - I'll get pics/vids up before the weekend is over.
:D
No More Oldsmobiles 02-26-2005, 06:18 PM Uh-oh. More hp and it's silver.
DARKMAZ8 02-26-2005, 06:34 PM :eek: details pleez!!!!!!
truemagellen 02-26-2005, 06:40 PM variation is common...thus tuning can really make a difference with no additional mods
truemagellen 02-26-2005, 06:42 PM Uh-oh. More hp and it's silver.
haha!
The car is just a stock rx8 with 14K miles. nobody is sure why, but his car stays nice and (safely) lean...unlike ours which dip into 'pig rich' conditions.
When we get $, we're thinking about swapping his MAF/ECU into another car to see if those could be causes.
What flash is he on compared to you?
dannobre 02-26-2005, 07:15 PM Same flash as far as we can tell. It was quite a day. I have all the data on a CD...so when I get it organized I can send it to everyone concerned if they want it.
I have a problem with my car....for whatever reason it would max out at 130+/-. Ran it twice, six or seven runs each...with new gas in between...checked the plugs. It has run OK til this AM...and it crapped out on the way to Kirkland to the dyno ....after a fill up at a Chevron??
I ran it down to 1/4 tank...refiled, and dyno'd again...same thing
Anyone have any ideas......I also ran it with CZ on, off, out, reset. doesn't seem to be the piggyback it altered the A/F as expected, just no power. Coilpack??......By the way... the guys at Carbconn were great! www.carbconn.com (http://www.carbconn.com). I guess I'll have to take it in with the dyno graphs ( the stock ones :D) and get them to take a look
Xyntax 02-27-2005, 01:18 AM Cool! You guys had 8s running dyno too! Four of us did ours here in San Jose. Check out our results at the West Forum.
IZoomZoomI 02-27-2005, 01:24 AM dam 206 stock... where is this guy!? That's what rx8 should be. Wonder what mazda did right with his car.
Xyntax 02-27-2005, 01:43 AM ^ Probably screwed the ABS interference in the ECU thus freeing his RX-8 to run the way it should on a dyno :D
Nemesis8 02-27-2005, 01:44 AM How about a teaser vid of our day. This was the highlight of our day. Click on the teaser.wmv (http://www.hausers.com/nemesis8/videos/teaser.wmv) file. It's 3186KB

Finally, we got the counterexample. All us owners are going to owe you big time. How are you dynoing the cars? Everything Canzoomer said to do? Avoided limp mode?
IZoomZoomI 02-27-2005, 01:51 AM straight through aye? who's car was this?
Nemesis8 02-27-2005, 01:53 AM How are you dynoing the cars?
Dynojet
DSC/TCS Disabled
5th Gear Pull
Wheel sensors left on the car untouched
Nemesis8 02-27-2005, 01:57 AM straight through aye? who's car was this?
That was a "Fastmike" mod to see what it would do. I missed the second pull flame. It shot out three feet! That was the third pull flame.
Were all of the dynos run in 5th?
Fanman 02-27-2005, 02:02 AM So Nemesis, how much did you pull ? Was over at the So. Cal. meet met a few RX8 club members, had a good time.
jenkins-crew 02-27-2005, 02:04 AM maybe I missed it but what year was his 8?
MazdaManiac 02-27-2005, 03:58 AM ^ Probably screwed the ABS interference in the ECU thus freeing his RX-8 to run the way it should on a dyno
Myth. ABS (more accurately - TCS/DSC) does not interfere with dyno runs on this car.
Finally, we got the counterexample. All us owners are going to owe you big time. How are you dynoing the cars? Everything Canzoomer said to do? Avoided limp mode?
There is no "limp mode" - at least not for these reasons. It is documented in datalogs while on the dyno. The ECU does nothing to pull power just because the wheels aren't spinning the way it wants to.
The ECU can affect power three ways - through fuel deliver, ignition timing and throttle position. It changes none of these while on the dyno.
IZoomZoomI 02-27-2005, 04:21 AM my abs light did turn on after the dyno run, so did one other owner. Can you explain this?
MazdaManiac 02-27-2005, 09:29 AM my abs light did turn on after the dyno run, so did one other owner. Can you explain this?
Yes. Your ABS system didn't like seeing some of the wheels spinning and others not. This has been the case with ABS systems for decades.
However, it does not cause the PCM to pull power as others have claimed (provided your TCS is off).
why the loss from the flywheel?
It should be less than average with eletric steering/carbon fiber drive shaft, etc.
Nemesis8 02-27-2005, 10:41 AM So Nemesis, how much did you pull ? Was over at the So. Cal. meet met a few RX8 club members, had a good time.
Here are my pulls attached. The site conditions were: 59.86 Degrees F, 29.94 in-hg, humidity 45%, SAE: 0.96
One oddity I noticed yesterday...
All/most of us dyno'd about mid-140s lbs-ft of torque...that's about a 10% loss from the factory rating of ~160....I wonder why the car appears to lose much less tq thru the drivetrain as it does HP.

That's not loss, that's Mazdas new math formulas for calculating engine horsepower ;)

LMAO!! NICE :)
Fanman 02-27-2005, 01:36 PM Wow, 187.5 whp on your best pull. You guys were getting some great pulls up there. I wish I was getting that stock (w/ cat back, instaed I got 179 whp) & that guy with 206 whp...WOW. I guess he doesn't need a CZ unit to tune his car.
On the dyno being variations I think these are the best dyno pulls I have ever seen. I think the tq # (159 lb.-ft.) might be more realistic than the hp #. It seems from our 0-60, 0-100, 1/4 mi., & other hp dyno #'s & this car actually runs around 220 hp (not 238 hp), or closer to the European specs (stated 228 hp) if the dyno #s are correct.
Nemesis8 02-27-2005, 01:58 PM It's amazing what a properly tuned Renesis is capable of on a bone stock car. The 206 pull had us all amazed. Dannobre has the data log for the 206 car. We are waiting for him to post it.
I'd like to see Racing Beat fix this PCM one day...
rx8wannahave 02-27-2005, 03:05 PM From what I hear RB is starting to tune the ECU? Is that true...if so, when do you guys think they will have something.
I'd like to see the guy send his ECU to RacingBeat - to see if they can duplicate things. :)
dannobre 02-27-2005, 03:23 PM Just got home...I'll post an excel graph off the Canscan log of his car inn a bit
I wish I had more time to log a lot more values...to see if anything was different.
dannobre 02-27-2005, 05:06 PM Here's the pics of the Dyno Graph for run 3...don't have the 206HP run...might have been on the all gear run?? Also the CanScan Graph with timing and A/F values.
Note..the 12.05 flatline values over 75K are all righer than that......it stops reading at that value.....could be a lot richer. Renwar1...post a copy of the Picture if you have it from the dyno
This is in 5th gear.....
since you posted a graph first, he can't get mad at me :)

neit_jnf 02-27-2005, 06:15 PM i don't understand that last dyno... :confused:
going through the gears?
truemagellen 02-27-2005, 06:20 PM i don't understand that last dyno... :confused:
going through the gears?
instead of a single gear dyno you run through the gears to the top
ie 1st gear up to 9k shift to 2nd
rev 2 9k, shift to 3rd, and so on
Nemesis8 02-27-2005, 06:31 PM Close, but we went thru 1-4th to get up to about 2500-3000 RPM, then shifted to 5th and gave the thumbs up to the crew and put it to WOT. Then we watched the RPM's and Canscan to know when to let off and shift into nuetral....
We also did a couple of spirited dynos by rapping out each gear to see what the data logs would produce on dan's laptop canscan. It seems 4th gear pulled the highest doesn't it...
Is that right Dan?
Where's "renwar1" when you need him??
dannobre 02-27-2005, 07:39 PM Looks like 4th Gear gives the highest results on this car. dmp did an all gear run...his maxed out in 3rd/4th....so I think 3rd and 4th gear dynos will be better to run....less wear and tear on the car...and on the dyno

I dyno'd my car with all of those guys, but I brought my S2000 rather than the RX-8. My torque was 145 corrected, 152 uncorrected, which was not all that much higher than most of the RX-8s ran, but my HP was 210 corrected, and 219 uncorrected. Since the engines have very similar torque curves, and both rev very high, (and are rated very similarly--my S2000 is rated 240 hp and 162 ft-lbs of torque), I don't understand why fairly similar torque numbers translated into such different HP numbers.

Yup...doesn't make a lot of sense. :(
Great meeting you, btw :)
abbid 02-28-2005, 01:26 PM I could have sworn that PoLak was pulling something close to that.
bump - anyone care to offer opinion on the % lost ?
e46328 02-28-2005, 05:45 PM Yup...doesn't make a lot of sense. :(
Great meeting you, btw :)
Man,,, I wished I could've gone to the dyno. I will try to Join next time!!
BTW, I think S2000 has more HP since S2000's torque in the high RPM range doesn't drop as much as ours.. HP = (Torque X RPM)/5250....
So the difference in HP between S2000's and RX8's can be explained by how much torque you have at the peak HP rpm... etc not how much peak torque you have :)
PoLaK 03-01-2005, 07:01 PM Hummmm not to down play your results BUT in my experience the higher the gear the dyno is the more inaccurate the results are because of the higher wheelspeed and for some reason the inaccuracy always favors higher horsepower numbers. This is just a piss in the wind but if rotarygod or mazdamanic could explain why?
Abbid my best dyno was 187rwhp in 3rd gear. I did a 5th gear dyno once but it was on a different dyno it resulted in 187, the 3rd gear on this dyno was 178 so I may be on to something. Don't have a soft copy of it; I did it to see what the leanest points for gas mileage were.
Now lets also remember that the Rx-8 runs different maps in each gear due to increased load on the engine. For example the point at which you start getting lean in 3rd gear is much later then the point you start getting leaner in 5th gear.
Not sure how but this may be helping you, but it may be a possibility.
Did you remove the mufflers? If not what the hell is that thing shooting flames, if you remove the mufflers of course you’re going to make more horsepower, then normal.
Also was a 2004 or 2005 Rx-8, although it’s not that big of a deal because ITO did Dyno 196 or 198 on his 2004 stock car.
PoLaK 03-01-2005, 07:20 PM After watching the 15MB video Im going to go under the assumption that you removed the exhaust system.
Quoting racing beat:
3. Mufflers – muffler & connecting pipe - 2-3 HP.
4. Removing the muffler from the car (engine) – about 4 HP.
5. Remove catalytic converter and resonator from the engine completely, and replacing with "cat" replacement tube – max benefit 8 HP – regardless of what muffler is used (or even no muffler).
So if you removed everything back from the headers you should see about a 15HP increase, subtract that from your 201 or 198 run and you get to 186/183 which is where my car is. You still have a GREAT car just not that GREAT
Maybe slightly more then 186/183 because im unsure if racingbeats numbers are talking about wheel horsepower or crack as they have an engine dyno.
As stated, only one car - the flamethrower, had it's muffler removed.
The further away from a 1:1 Gear ratio, the more innacurate the results. ;)
I'd say all of the cars are 2004 models.

Bad assumption to make ;) See above. The 206whp ran full exhaust...full everything...100% 'off the showroom' (except for springs and clear corners and some dirt. He may have had some CDs in the car... :p)
The Car with the flames - again - the only car who ran sans muffler, (Midpipe and cat were left in place) got in the low 190s.

5th gear!!!! ahh, so thats why it sn0wed a foot here yesterday - people actually decided to dyno in the right gear!
Polak - 5th gear dyno's higher not because its inaccurate, but because your lowering drivetrain losses by keeping the drivetrain acceleration down and in some cases using a straight thru arrangement in the tranny. When people quote the "normal" drivetrain loss of 15% thats referring to the drivetrain loss in the 1:1 gear.
funny - this thread didn't have anything to do with 'Aftermarket Performance' nor 'MazdaSpeed'.
Weird...oh well...looks like it has a new home :)

PoLaK 03-01-2005, 08:12 PM Well to test out your theory on 5th gear dynos, I'll try again, I'll be heading over to a dyno for a RxTuner article within the next 2 weeks I'll do both a 3rd gear and 5th gear baseline.
Btw for anyone curious as to what were doing, first im going to the dyno to get a baseline, like I said 3rd and 5th gear. Then im heading home to pop the car on the lift and install my Racing Beat flywheel and Mazdaspeed clutch yes I'll do a really detailed DIY, Then im going to the dyno to see what difference these two parts made.
Then I'll install the Racing Beat Exhaust in the shop, the double tip not the single tip racing one they have. Dyno again and finally install the RB intake and dyno again.
Moving to tech garage. (omi what were you smoking)

I don't think you're interpreting those numbers correctly, though I could be way off. I think what RB said is that with everything removed, you would see an 8 hp gain. They mention no muffler, no cat, just a replacement tube and from there you'd see a gain of around 8 hp. One of the more enlightened should easily answer this question though.
A 5th gear dyno with a fw won't show measured gains - at least according to math :)
hehe

Nemesis8 03-01-2005, 09:49 PM Can't wait for the review in RXTuner.
Hey dmp - wanna go watch me dyno this weekend in Tacoma? I'm not going down to Portland, even though it looks like fun. Is TurboTech open on the weekends?
they are open by exception only - for group dynos. This weekend may not work for me - Mary's got surgery for kidney stones this coming monday; we'll be prepping the house (cleaning, mostly).
Nemesis8 03-01-2005, 10:03 PM Sorry to hear that - Lee, my wife, passed hers several years ago, and then pathology lost them! So we don't know what caused them! Her father had them also.
Polak, be sure to write up a review on the RB intake (green with envy) and the MS clutch. Im curious how the MS clutch is compared to stock.

Pressure plate is lighter then stock but its still somewhere around 25-30lbs, HEAVY. And that big round thing in the bottom right is the throwout bearing we all love to hate so much hopefully when im done it won't be making any noise.
Anymore questions start another thread and direct me to it.

This is just a piss in the wind but if rotarygod or mazdamanic could explain why?
I'd like to piss your party as well. I'd link to think that the higher speed the wheels can generate, the better the sampling rate the dyno is going to get. Thus, the LOWER the error % you'll get on your results. Of course, I could be wrong again...but then, you would have to talk to my Instrumental professor about sampling and using the right scale to measure & calculate. :p
Same thing applies to "fuel economy" if you can put the pieces together.
PoLaK 03-01-2005, 11:18 PM Two separate dyno places Turbo Trix and KD Rotary both told me they don't like to do high gear dyno's. TurboTrix said because its more inaccurate because of higher wheelspeed KD was because of that and not enough cooling on the oil coolers.
Only speaking from the experience of reputable shops... thats all.

I would only ask those reputable shops why are they so afraid of a 60 second, higher sample rate <<(keywords) dyno run.
Hey, and I am only speaking out of 3 years of dealing with electronic friggin' instruments and people bitchin' because sample rates were not adequately high enough! That's all. :D
At the end of the day, you want to get the most repeatable, accurate results you can get. Not the highest ones.

if your testing out gains from a flywheel, your going to see a good gain in 1st gear, less in second, less in third, bearly anything in 4th and nothing above
MazdaManiac 03-02-2005, 11:59 AM Gains? There will be no horsepower gains from a flywheel and a clutch.
However, the time to cover the entire rev band may be somewhat shorter.
Right - said another way:
The car should accelerate 'as if' it had 10? More HP in 1st gear...6 more in 2nd...and so on.
:)
r0tor 03-02-2005, 01:00 PM depends what you mean by gain...
will there be a gain seen at the crank - No
will there be a gain seen at the wheels - yes, as less power is consumed spinning the flywheel
if the car is in gear and it "revs faster" the only way its going to rev faster is if the car is accelerating faster, which means more power is reaching the wheels
MazdaManiac 03-02-2005, 01:33 PM depends what you mean by gain...
will there be a gain seen at the crank - No

if the car is in gear and it "revs faster" the only way its going to rev faster is if the car is accelerating faster, which means more power is reaching the wheels
Unfortunately, that is not how the physics work.
The actual change in mass is not where the gain is felt with a flywheel. It is the lessening of the inertial load that changes the response time and inertial moment during rotation.
The total mass reduction isn't anything as far as power is concerned - you would have to take 100 lbs off of the FW to have it show up on the dyno as power.
In fact, lightening the FW will reduce torque as it shows up on a dyno.

DARKMAZ8 03-02-2005, 03:06 PM Im getting real tired of dyno graphs.....real performance data will always be found at a track...dyno is only a useful tuning tool not a way to measure performance....imo
PoLaK 03-02-2005, 03:10 PM I'm under the impression that torque will only be lost slightly at lower Rpm and that there will be a slight increase in wheel horsepower due to a decrease in drive train loses, is this difference so small that it can't me measured by a chassis dyno or does it really not "exist"
Im getting real tired of dyno graphs.....real performance data will always be found at a track...dyno is only a useful tuning tool not a way to measure performance....imo
I agree its useful as a tunning tool or to compare if you're making gains with products your adding, you just have to do it on the same day, same dyno etc..... However, track performance its only as "real" as the driver so what good is that.

I believe the margin of error is greater with a dyno then a semi experienced driver.....trap speeds never lie ;)

DARKMAZ8 03-02-2005, 05:16 PM so thats what the Z06 traps in reverse......not bad ;) :D
r0tor 03-03-2005, 10:36 AM Unfortunately, that is not how the physics work.
The actual change in mass is not where the gain is felt with a flywheel. It is the lessening of the inertial load that changes the response time and inertial moment during rotation.
The total mass reduction isn't anything as far as power is concerned - you would have to take 100 lbs off of the FW to have it show up on the dyno as power.
In fact, lightening the FW will reduce torque as it shows up on a dyno.
unfortunetly it is how physics works as i worked out the physics in another thread about 3 months ago and showed the hp needed to spin the stock flywheel and the hp needed to spin a RB and MS flywheel in 2nd 3rd and 4th gears... and the difference matched gains reported by another forum member on a chassis dyno
I lined up with the Vette thinking "Uh-Oh...this guy has a solid chance to beat me)
Stage....Adjust helmet (The dude kept a helmet on the entire time).

GO!/Green!
I launch fairly well - 2.15 60ft, I'm banging thru gears - never noticing the flash of yellow Corvette I 'should' see in my periphrial vision. WOT into 4th gear now and BANG! I thought I spun a bearing...NO Power...Still no Corvette either...I put in the clutch - seeing the engine is still running and coast thru the traps to 14.5 @ ~85 or 90mph...still no Vette.
As I brake I Look over my shoulder to see him lazily driving down the track...16.7 @ 6x mph, iirc. Something like that.
The guy would just sorta meander down the track at every green, as if he was on a sunday drive.
(fwiw, I lost a coupling for my intercooler piping, if I recall - no damage to the engine)
MazdaManiac 03-03-2005, 11:00 AM That's a pretty sucky race.
Reactionary 03-03-2005, 01:10 PM I want to get back to dmp's real topic. Canzoomer or whoever gave the original phenomenon its name: "limp mode." I would like to name the new phenomenon: "HARD-ON mode." Remember, it all started here.
Reactionary 03-03-2005, 01:12 PM dmp, how can I get my car into hard-on mode?
dmp, how can I get my car into hard-on mode?
First you have to talk REALLY nicely to it....
DARKMAZ8 03-03-2005, 01:19 PM I wouldn't talk to snakes....especially one eyed pink snakes with darth vader helmuts....:p
124Spider 03-03-2005, 04:34 PM dmp, how can I get my car into hard-on mode?This is really too good to leave alone, but I will. ;) I'll give you a hint, however--My wife's RX-8 spends every night right next to my beautiful S2000....
xdrian 03-05-2005, 08:41 AM Hey p0lak, at what dyno are you going to do this? Turbotriz of somehwhere else ? i want to see for myself, what type of number you put down, maybe ill baseline dyno my car at the same place too.
PoLaK 03-05-2005, 09:08 AM I personally don't like TurboTrix kinda felt like they looked down on me because I wasn't driving a mitsu or a subaru.
I'll either be KD rotary (reading, PA) or AutoTeknik (Flemington NJ), but I have to speak with one of the two first.
takahashi 03-05-2005, 09:16 AM Interesting... is that what consistently you find???
Best dyno in 5th.
So I have been lying to myself with the low figure with the 3rd gear. Maybe there are actually 20whp more in my car I have not found?? :p
PLease confirm this and thx in advance :p Happy man ;)

You might possibly be spanking it too hard, which can cause premature choking. My suggestion is to relax and let it flow. Only then will you reach the elusive hard-on mode.

Yeah, they are always liek that, but thats becasue they are serious about thwir work, they dont want anyone just saying this and that and not doing it. My bro goes there all the time, once they get to know you, they'll be a lil friendlier. Well
let me know i want to check it out.
