They really didnt say. That was kinda my point

Power!!
There ar a few turbo kits on here that make 330-370 rwhp and there is also a safer easier Pettit Supercharger that many people run 330 rwhp with about 220 rw lbs torque and with the SC the car gets to retain the factory redline of 9000. The turbo kits tend to die off at 7800 rpms
Properly sized turbos are making much more power and torque than SCs all the way up to redline.
There is opinion both ways so try not to make SC vs. Turbo type comments.

Having said that.. Whether you go SC ot Turbo if you plan on revving into 9k+ you'll probably also need a very efficient and large FMIC.

That's still a tall order because most CHRAs are spinning so fast by that time that the amount of heat they'll generate is gonna be of negative effect.

The Greddy unit runs out of breath up top because it's too small for our cars. It makes great low end boost and power though.

If i want to make power for what im doing, i would go and rebuild the engine, upgrade the Apex Seal from Esmeril if it ever comes out lol hope it does. and then Port the engine. Then slap on a turbo and tune it. hmm fly wheel and clutch for sure haha and also bigger injectors and upgrade the fuel system and ignition.

I still have yet to see a reliable 400rwHP setup. The esmeril thread kinda went:
"414RWHP!!..rabble rabble rabble...rebuilding the engine...rabble rabble rabble... now shooting for 500RWHP"
Not saying it cant be done, but nobody is currently driving around 400RWHP turbo'ed Renesis with months of trouble free operation as such.

The only reason we opened the fully operational engine (After a year running at 16psi, 400whp range) was because we needed to test our new apex seals...we didn't want to launch a product without testing it and I am sure people in the forum appreciate that.
I have never said you can't get to 500whp on a stock internal engine and keep it there reliably...you just cant make any mistakes in the tuning process. Once its tuned there is no reason for it to break unless you run out of gas while generating 500whp and it detonates. Regardless....and reliability aside, anything above 450whp would require higher octane fuel, built engine or not, because our compression limits the engine in that aspect. A switch to E85 is ideal since you can get it cheap at the pump...after that....even 500whp is surpass-able on stock internals.
Best regards,
Chris

I never suggested you said it caused the rebuild. I simply pointed out you never said it didnt either. Unfortunately with the few details you guys release I am given very little evidence to believe otherwise and am forced to make my own guesses as to the happenings between updates. I read that entire thread and that is the impression I got.

Search up on this forum on some of the boosted build kits and turbo sizing. There is a ton of good information on this already published on this forum in this section.

Has anyone tried using TII rotors on the renesis to lower compresion and allow for more boost reliably??? i know there are older 13B PP's running renesis internals for higher compression so...dont mean to thread jack just trying to find alternatives for this engine......

Horse Power: The naturally aspirated Pettit Built Renesis when properly tuned with ambient temps around 70-80F, using a header and open exhaust will produce 245+hp or 210whp @ 8800 rpm
The same Pettit Built Renesis with our forced induction system, (supercharger) running 8-10 psi boost and maintaining charge temperature of less than 135F and again properly tuned w/ a header and open exhaust can produce 365+ hp or 330whp @ 8400 rpm.
With Turbo charging @ 12-14 psi/boost and maintaining a charge temperature of <125F with a .8:1 or less backpressure ratio is capable of producing 200 hp / rotor, or 400 hp, sure more boost makes more power but then other factors like material strength and management errors become more critical and these variables can lead to unexpected failures.

that is a crazy silly guess.
stop trolling.. shoot us a note when you have a car..

I fully believe Petit can have a Renesis that does about 210 at the wheels. Nothing out of the ordinary about that. The engine can easily do it.
As for TII rotors in a Renesis, you can't do it. No need to get into details again. Just trust me. Don't try it.

Would you mind me asking when we said we were rebuilding the engine in order to attain more than 414whp? Or the fact that there was engine failure when generating that power on a stock engine?
The only reason we opened the fully operational engine (After a year running at 16psi, 400whp range) was because we needed to test our new apex seals...we didn't want to launch a product without testing it and I am sure people in the forum appreciate that.

Nice bump. Don't even pay attention to that post because he is full of ****. 500WHP on Renesis is a pipe dream, hell anything north of 400WHP for any decent length of time is a pipe dream, built or not. The turbo kit his company sold was the biggest failure of any RX-8 turbokit.
