Thats pretty close, you can tell that extra 6mm is helping you up top. His falls off around 9200 and peters is pretty flat up to 10500. Thats pretty badass, but that would allow for traps higher than nhra wants to see.
10500, is just crazy, thats A LOT of stress on the crank. Peter assemble the motor, or have it sent to Jim Justice or some place?
peter builds and assembles all his motors....no one does but him. only thing that other people do is porting of head, cutting of valves, whatever the machine shop can do.
what would make u think he has someone else build his motor??? J/C
its racing... anything above stock is alot of stress

94 Supra= 500rwhp
Just wandering, i know most people that build motors for that kind of power don't assemble them themselves. I didnt know if he had opted to send it to Jim Justice or something.
Danny, I was just stating the difference in the turbo's from what the NHRA limit is. For the restrictions they have the 42R is the best. Peter is right at 540whp @6500, but i see what you are saying, its making 100 more whp.
Mike, you are not yelling at us to rev it higher, we arent the ones tuning the car..... Most dont rev over 9500rpm, powerband is an opinionated subject, especially since some engine managements allow you to launch at 20+psi.
yeah i think SFWD's limit is 70mm or was it 72mm
94 Supra= 500rwhp
if you hadnt asked I could have told you
The 4294 has the largest compressor wheel that they can use, 72mm.
the 4202 is a 74mm.

Fuck SFWD. TurboStreet is where it's at!!! hahaha j/k
I'm debating whether to go air/water or just regular front mount. I doubt I'll ever race at a NHRA event. They are mostly west coast events except for Moroso or Atco.
It's amazing the powerband of Peter's car and how it fast that big as turbo spools.
I have to rebuild shortblocks every once in a blue moon here at Nissan but when my block gets back we all know that Peter's assembling it!! I trust my work w/ a customer's car but just like many raceshops throughout the world THEY TRUST SOMEOONE ELSE TO BUILD THEIR RACE CARS!!
Now hopefully I'll be building my own streetcar motor sooner or later but NOT the racecar. I don't care what people say about me but I'm a realist as I've always said. Just keepin it real.
Quality Perfomance and Fabrication!!
Motor was asembled by Peter, so if it blows he can only blame himself.Also we dont plan on running NHRA races so for the Ndra the turbo is perfect!! He couldnt run NHRA if he wanted to the air/water intercooler
Ok compare it too this gt42r dyno chart car was fully tuned!

Danny, this goes to show you how illiterate you are...this dyno is on a gt4202r...WAY bigger then my turbo.
And Bee...I have a non dual BB 4294 now. When I went to Cortney's house to pickup my stuff and he showed me a dyno overlay between a gt4294r and the regular journal bearing gt4294 and it hit 827whp by 6800rpms. It spolls as fast a a t4 pt67. I seen the dyno and I was in doubt until I seen the dyno paper. Below is the dyno paper:
Really are you
