PFS tuned GT42R makes 643rwhp!!!!
 

--------------------------------------------------------------------------------

Went back today for some final tuning and Ray made some huge power! At 31psi it made 643.9rwhp and 520 torque! Holy shit, even if I can't drive, I gotta run 9's!!!! HUGE PROPS to Ray. The man is a wizard. This is all on a PFS street port and C116.

:eek:

Damn, that is a lot of power. Would you ever consider going 20B, Ernie?

holy hell, that is impressive and intimidating

wow that's impressive numbers.. sounds like you may have a hard time keeping it straight.... at 31pounds is their still room to grow? 35-40pounds??? just wondering when it will end..... congrads once again

There's alot more in it, but I only have a 3bar map sensor so Im at my limit right now with boost, but Im HAPPY with the power Im making now....lol....I can't imagine more. I need to get some seat time with this power level.

sweet lord.

Damn!

X...

crap thats alot of power!! I bet thats a hell of a ride

uh, this can't be driven on the street at full boost it would be insane. Imagine this on a 20b :D

Holy hell man....

HOLY GOOD GRACES OF GOD... lol.. i just wanna know one thing, if i ask for a plane ticket to MD for christmas, can i have a ride in your car?

Spectacular result.

WHOA!!! congrats!! thats kick ass!

Thanks guys, I just need to get it down the track in one piece now!

Nice numbers :cool: Have fun - as long as you don't break anything I look forward to reading about 9s :D

Egad!

Eh, that turbo is small and girly... it's gonna run outta steam around 825 rwhp at about 40 PSI...

heheheheh j/k :)

I wonder how many passes that engine is good for. LOL

Im not worried about the engine. Thats rock solid. Im worried about my tranny and other parts in the rear.

I don't have much experience with the Mazda trannys. I am used to LS1 swaps that use T56 transmissions. They are practically indistructable. However, even the V8 swap guys have to deal with rear end longevity. I have broken my TII rear once already with 360RWHP.

The trick to keeping the trans and rear alive is in the launch. You can't just side step the clutch and hope for the best. I have had really good luck with launching my FC by preloading the driveline at the line by lightly slipping the clutch. You need to have line lock or use the e-brake to do this.

Good luck!

LOOK OUT Tony Schumaker!! here comes ErnieT!

OH my god. I just saw this thread...and I think I just pooped my pants. Thats an ungodly amount of power. Post a vid of this thing...Please....You know you want to...

Great job man.!

Thanks guys. I appreciate the compliments. Hopefully this spring I'll be able to say I have a 700rwhp RX7! Thats the goal. Ray Wilson of PFSupercars is building me a bridegported motor with a few other goodies to be able to withstand 40 psi!!
