A turbo what you might be asking? Well, a turbo RX-8!

Here's the abreviated story: (no need to Viggen me :)

The guy that posted here before that was doing a turbo on his WB car is local to me. So I gave him a call and since he was in the shop today, I stopped by his place to get to know him and check out the place. This is a pretty much dedicated rotary shop he's at. The stacks of housings, rusted rotors and other misc parts where a pretty good indicator. Of course, the Second Gen drag car, the multiple 3rd, 2nd and 1st Gens also hinted at it. I got a chance to check out his 3 rotor FD while there, etc. Basically, I'm saying the guy knows rotary's. SO I got to check out his Blue RX-8.

Upon opening the hood, it looks like he just has a K&N intake on it. However once you remove the engine cover you see there's some extra tubing there, and not a straight pipe from the air filter over to the cars intake. When you start getting on your knees you can see the intercooler in front of the radiator. The turbo itself is pretty much invisible, in the rear left quadrant of the engine bay. It's a super clean install. If you didnt pull off the engine cover you'd never know whats happening with the car.

Next, sitting in the car. The Boost controller is sitting in the ashtray location. The cr runs buttery smooth when cranked. I mean it idles better than stock IMHO. The noise is also very nice as it is almost stock (with the turbo manifold muting the intake so it isnt as loud as a short intake), with that distinctice turbione whistle in the background. Driving it around without going nuts is very nice. Not loud at all, and you only hear the blowoff valve doing it's thing. Car is very well behaved. But lay the hammer down and lookout! Spools up by 3500RPM with the current settings and using a G-tech, pulled a 12.3 1/4 mile. Same G-tech on a stock FD showed a 12.8 I beleive. The noise as it spools up is amazing, and the car just takes off like a bat out of hell. Traction control needs to stay on cause it really hauls ass now. The specs as it is running now is 6 PSI, everything stock on the engine with a custom built piggyback computer unit. This is good for about 100HP estimated. This is NOT the final tune however. Final tune is planned for 12PSI using a stock engine, just upgrading the fuel injectors. No Seals are changed, nothing else is done to the engine

Hopefully he will have the car ready by the end of the month. When he's done tuning it and finishes all the details (making the kit look pretty and such) I'll take some pics and post them up.

So I'll say this. Hot damn! Cant wait for my warranty to finish out, and save some money! This should be awesome. BTW, if anybody is in the SoFla area, he's a cool guy and isnt shy about showing it off. Let me know if anybody else wants to see/hear more about it.

sounds great now what company is the turbo from or did he make his own? price

:)

Thanks Genom. We won't viggen you, this time!

Yowza! 100HP at 6PSI is nice :). I'm not so sure about pushing it up to 12PSI, but it's good to know somebody is out there doing all of this testing for us!

Genom has been to the top of the mountain. And is it good.

that's awesome that there's a quick and running turbo out there...i have 234465432 questions, but i think now I need to make a trip down south!

are you anywhere near Sana bell Florida ?

im goin thier on vacation in a few weeks

Holy sheep dip, batman!!! 100 HP at 6PSI and a 12.3 1/4 mile???? OMG!!!

I definitely gotta get me forced induction!!! :D

For cryin out loud. Just when I think this car can't make me any poorer...... The worst part is, you know you have to get it when it comes out, no matter how much it costs. I can't wait.

more info.... :D

this has to be turobo8rennisis's set up right...ya know...the thread thats been "closed" for the last month....right?

Sweet! My folks are 2 minutes from Miramar, too :)

Damn you, Genom... green w/ envy here...
thanks so much for making my day though...

someone needs to get videos, im very happy to hear such a great 1/4 time, but it just doesnt seem that 100hp=over a 3 second drop in 1/4 time....just seems a little odd to me.

Was it a rolling start or dead start to the quarter mile G-tech run? If it showed 12.8 for a stock 3rd gen then it is a second too fast. A stock 3rd gen with a perfect launch does 13.8. I could estimate this RX-8 doing a realistic 13.3 or so which is GREAT!!! running with stock EVO's and STi's now...

There are 13B's running 16-20 psi and more with stock internals, just proper fuel and tuning and this is with 9:1 or less static compression ratio. I don't see any trouble on bringing the Renesis up to 12 psi as long as proper fuel and tuning is added as well... IT"S ALL IN THE TUNING!!!!

Great job!

Yep Its turborx8 aight.Ive spoke with Adrian as well and seems to be a sharp guy.He told me basiclly the same thing with one difference.He said that the 12psi setup moves a motor mount and will not be sold to the public.It will be and in shop install only for now.The 6psi he is running now will be sold and they are working on the motor mount thing to make the install easier.He will not be posting anymore here and i cant say i blame em.

I dont think he was selling anything as thier kit was at least 2 monthes out from his last post.People here scream for info and when he gives it he is expected to pay to do so?He would have been happy to pay for advertising when he had something to sell.Shows where the real interest of the owner of this site is.Sad :(

Man this is awesome!!! I am going to have to give Adrian a call and check this out.

LOL!

Man, that is classic. :cool:

The 12.3 time was with 10PSI, not 6. My bad, didnt explain myelf properly. The car has run 10PSI, just not too well since it still needs to be fine tuned. Thats pretty much all thats missing. That and polishing the manifold :D

Edit: Once the car is tuned to the end specs, I'll be getting some video's and pics of it on the dyno, etc. Some in car video's would be nice as well I'd imagine.

I'm interested, when can we make a run to his shop.

send him to the rx8web.com site so he can sprew the juicy details!!!

^^^^ Just let us know when he does!

Epitrochoid, guy321... you guys wanna caravan out to this shop one day??? Maybe next sunday? I REALLY need to check this out. 10 psi sounds like exactly what I need :) You guys up for it?

12.3 1/4 MILE !? You are halling ass there buddy. Evo's and such are 4 wheel drive and the 8 is known for wheel hop. I mean a 12.3 aint far fron a sub 12 1/4 mile time!
I'm not doubting what ya saw man and I appreciate the time it took for ya to get this info to us but its just hard for me to believe that this car has the possibility to do a sub 12 1/4 mile with the tires and rear end setup this car has.(in stock form). Still a working turbo and no ecu problems is great news! Keep us posted!
olddragger

Keep in mind those are G-Tech numbers, and from the benchmark he listed for a stock FD, it appears to be 0.5-1 second faster than reality. I don't want to downplay what he has going on there though...it is the best news we've had on the FI front yet!

jds

ive ran gtech for a couple years now, and whenever i go to the track its always dead on, or 1/10th of a second off....so i believe those if they are used properly

I would go, definitely.. but I'm going to be in NYC this coming weekend.... If the weekend after this one was what you ment.. I could be up for that.

That may be, but the stock FD was not a 12 second car. Most times are in the mid-13 range that I've seen.

i aggree. a 12.3 sec 1/4 mile with a 100hp increase from stock numbers doesnt seem right. i want to see this. Genom, can u take pics on the engine bay so we can see the set-up??

Im curious - get a camera and take some pictures

I will try to get there next week. This week is gonna be very hard for me at work. Soon as I can I'll take pictures and get the numbers again, since I probably mis-remembered something from oogling at the car so much :D

Have patience! I will get more info.

SA-WEET!

CANT WAIT!!!! :D

hope it wasn't the 1/4 times :)

Either way ANY improvement is a step in the right direction to soothe countless arguments against the 8.
I'll be looking forward to updates!!!

How's the fuel consumption?
Can it be done for the auto?
ahhahahahahhahahahahhhahahhahahahaa

The project car was A/T?! I didn't know that. Still, this is great news! If the gtech measured 1-second off, then a 13.3 sec RX-8 is still great news! Thanks for making my day Genom!
:D

It looks like I will have to contact Him and take some Pics this weekend.

You mean auto
If it's turborenesis's car then it is a MT.
Read his posts.

OMG I MEAN AUTO. MY BAD....

I livenear this guy. Once he offersa price on the turbocharger Ill take my auto downthere and see if he can do anything for me

any pic that is taken under the hood, and the intercooler?

thanks

my hope for FI has once again gone up.

All this car needs to be PERFECT is 350 WHP, and to be able to take STIs and EVO's... :D

I'm dying to see some dyno's / vids. I'm also very interested in what approaches they are taking to ECU / tuning on this item.

Acording to Adrian, it's their own home built piggyback unit.

Omicron, if 350WHP makes it perfect, get ready for some fun. The car felt incredible with only 6PSI. I shudder to think about what 12PSI is gonna feel like.

the only way the gtech would be a second off would be if the user set it up wrong

I wonder what kind of gas mileageit gets haha

I don't doubt that. My only point is, before anyone says "OH MY GOD HE'S RUNNING A 12.3" keep in mind he also ran a 12.8 in a 13.5 or so car. So, he's probably about 13 flat in the turbo 8, configured as it was for the G-Tech run. Which, by the way, I'd kill for in my car :D

Can't be too much worse than the 15mpg I get now ;-)

Yes, I'm a newbie but check here often for inspiring tips on ways to tune the 8. I would love to add boost to mine, but have to wait for MS to do something there. I have to start small and safe such as a new flywheel, that's my next goal.

I'll wait for a few more of you brave ones test out third party turbo kits and I'll read with envy for now...

still waiting...........where are the twins???

i would put money on it that no one would TT the 8..it's not feasible..

run exhaust from each rotor to it's own turbo ... then you can have a nice biturbo setup. Then you can tune each rotor independant of the other, and have DoD like rotarygod was talking about ...

mmm, one can dream ...

I thought this engine had 3 tubes going to 1 exhaust to begin with? Or was it the intake?

you sure about that exhaust there shawnio? i've never run any exhaust into a turbo before...i think you got it confused there buddy...:D

whatever happened to the formula: high factory compression+high psi forced induction+factory seals=damage. Is that wrong?

It's an RX-8 now. Your formula applied to the RX-7.

So who is this turbo by and what are the numbers? Is this legit?

The car felt incredible with only 6PSI. I shudder to think about what 12PSI is gonna feel like.


Boom?

im sure we will see twin turbo rx-8s 13b and 20b swaps hahahaha

That formula is based on a piston engine and it's usually weaker stock internals in NA form. It was notrhing to do with the compression. The rotors (be it high or low compression) have virtually the same strengths. The key ingrediant with FI on a high compression rotary is tuning. I know a 13b with 9:7 NA rotors that makes nearly 600whp. Personally if I was going to run 12psi on the high compression Renesis, I would most definetly install a water injection system to kick in above 7psi.

With a 100hp increase, say 280 RWHP she should at least be in the 12.5-12.8 range... Not bad...

Not bad... Or did you mean Bad A$$... I would love for my 8 to run 12's. That would definately shut up a lot of the little 17 yr. old punks in there camaro's and the mustangs that continuosly rev there engines at me at every frickin red light. No offence to the younger generation in this forum.

Just take one of those punks through a turn. Who will be reving their engine then?


I know the answer, because I made a camero ss look stupid on a banked freeway overpass. My Rx8 @ 106 holding the turn clean and his SS having to slow down at 85 or so because he was leaning and loosing it... hrmmmm

mmm turbo, I cannot wait!

I hear ya.. The twisties are a blast in this car.

What shop did the work?

Did anyone ever get any pics?

Ok....

Now I am ... conflicted.

Just installed my CZ Stage One with the M flash in place. Liked the performance improvement based on tests on a lonely stretch of Interstate. Pulled a 6.2 0-60... as best as we could figure but nothing conclusive. Just felt a lot faster.

NOW.... you guys tell me there is a turbo alternative. Damn.

Maybe I will move the CZ to my wife's car when this system is ready for prime time. :D

At the moment there is no turbo alternative and i think the drive in a turbop Rx8 is aload of BS. Don't waste our time with BS stories if you cannot prove the gains.
I think i speak for every maz 8 owner who want results not fantasies

Riiiigth Kimba2
so we DIDNT see the ssr turbo 8 or the sunflower supercharged 8. those where......ummmm........not really real. Just becuz the are not being produced yet doest mean they arent out there. I mean hell how could thy be going for dyno numbers wiht no turbo gimmee a break. Just becuz you havent riddin in onw doesnt mean no one else has either. and you cant prove he hasnt. and the way I see it is, is the burden of proof is on the prosecustion.(You) I rest my case

The fact is that I have a lot of things going on right now, and I dont have the 3+ hours to go get some pics, then the time to develope them and post them, just cause your impatient. MAYBE after my sister leaves town I'll have a chance to go over and get more stuff. But if I dont, then tough noogies. Look at my posting history if you think I'm full of BS.

You sir, earn my Idiot of the hour award. Think about that next time you call me a liar.

Come on Genom, cetainly someone with 14 posts should be given as much credibility as you, with only a mere 1400+ :)

I for one, would have to say that I believe Genom, Because he likes beer. Seriously though, he has no involvment in the company doing the turbo (That I know of) except that he lives in the area.

He went out of his way to say that he would get pics, his personal life does not allow it. Good for him, too bad for you people who EXPECT him to do it. He doesn't have to. If it were me I would not do it just out of spite. Of course I happen to be lazy, so that helps too.

Back to the point, Genom seems to be a stand up guy. I belive you.

(now will you pay for my turbo kit too? :) )

any new info?

Left the guy a couple phone messages, but havent heard from him so far.

Bottomline, you slap on a turbo on the 8 and this car will be uncatchable. When this kit becomes available please let us know.

A) a 13 is not uncatchable

B) The 8 still needs FI that way Neons and WRXs can't pick on you

C) No way in hell 100rwhp will take 2 seconds off a 1/4. Gotta remember that's peak power and you don't know how fat the curve got. I say a 13.3 is what you should expect and be happy with.

a 13.3? that is cookin, and good enough for me, then you can sand a chance against, stis, evo8, mustangs, firebirds, gtos, camaros....

and i also believe a 13.3 rotary would beat a c5 corvette (13.0) on the highway.



in a closed coarse of coarse :/

i like that on the highway (on a closed coarse of coarse).
i would love to take care of a cupple local cars my self. i have the only 8 for some distance ,helps when u live in the middle of nowhere,but i would love to swing by this guys shop whin im in FL in 2 months to check it out and think about getting one my selfeven though id prefer a SC.

Doubt it. The C5 has better areo and usually traps 110+. Plus it's modded to stock you're talking about. A simple intake/exhaust combo on the C5 would be enough to ensure victory. Plus you can buy them for 20k now (used of course).

But I would be more than happy to be a 13.3 in the 8 none the less.

But..the corvette is an ugly power beast...IMO..american muscle is so very ugly and that's all it is..power...

Can anyone confirm he blew it up?I heard through the grapevine 13psi and it went boom.I hope im wrong.

I wouldn't doubt it

13psi in a 10:1 rotary? I hope he was running 105 octane or sub-zero intake temps.

2mm seals - crack
thin wall lightweigt rotors - crack
It's a lot to ask of the stock RENESIS

Could you switch out the high compression rotors in teh 13b-msp for low compresion ones out of a 13b-rew? I know you may have to change out the stationary gears and what not. But i can' tfind anywhere saying that this wouldn't work... just not too many people have cracked open the engine, to mess with the internals. If anyone has a clue abou tthe internal swithability of 13b parts please give me a pm. thanks a lot guys.

thats a matter of opinion, the corvette is very attractive imo, and it handles great! stops great! and goes fast.
trans am has an awesome look to it, (ws6) the ss camaro is good looking also....

I haven't even finished reading the review by Seiji Tashima, one of the leading RE designers at Mazda, and I can already tell you it won't work. Why? The seals alone are entirely different for various reasons. One is becuase of the change to a side port exhaust instead of peripheral port exhaust. The Renesis isn't looking very interchangable with any other RE parts... lots of changes were made that seem to make it incompatible.

Actually I am wondering about the viablility of FI on the Renesis as well however...

what's wrong with 2mm seals? The 13B-REW has 2mm seals. Although the 13B-REW's apex seals are 3 piece instead of 2 piece like on the Renesis.

Instead of thinking about 13psi in 10:1 rotary... what is the effective compression ratio in a 13B-REW when you're pushing 20+ psi? let's compare that figure to the effective compression ratio we get on the Renesis at 13psi.

How reliable is an FD at 20psi? On pump gas with a good and properly tuned management scheme.

I have never built one, but I would guess that it would be on the edge any time you go WOT with it. Is it not fair to say that stuffing air into the engine at 20psi is for someone that is prepared to replace the engine at any moment?

I am talking about street application. I know that race applications go way higher than 20psi, but that is a different topic all together.

Wow, this all sounds pretty awesome. One of my friends on my ship is planning on getting a new 8 when we get back from deployment. I'm sure he'll be ecstatic to hear about this development. He might just be able to keep up with me then. :D

Any new updates?

Guys,
I hope not but is this just another collapsed turbo story? I mean, I believe Genom had the ride but it's been a month now and no info. If someone is succesfully running a turbo it seems the doors would have been beat down to get to them. I wonder if it blew?
olddragger

Welp, I've tried calling the guy a few times off and on with no results. I might be able to stop by the shop this saturday, but I'm guessing the 12PSI testing might have had some bad side effects (only reason I could think of the guy not wanting to sell a pile of these).

Keep trying Genom. Thanks for all of the updates..........
