Before the latest tune and the APS top mount, he was hitting 12.8 with not so great 60's. Not that I can do sh*z for launching. They think mid to low 12's I think. He also blew his tranny last time roasting all 4. 2nd gear byebye.....

pretty much what wrexr said....i hopin for low 12's...after my most recent tune and addition of that APS top mount, i noticed huge midrange and top end improvements....fourth gear pulls hard too redline...and i mean hard!!!! By the dyno plot you can tell it's carryin high boost all the way to redline....Next wednesday i'll be at Infineon attemptin to blow another tranny!!!

That is one sweet looking RS. How much did the motor swap, labor and motor cost you. I have a 2000 RS and am thinking about dropping an ej20 into it. You should get clear side markers for your car too.

wow a VF35 huh? i thought those were smaller than the 34s. does it still have the ball bearing center section? i just haven't hear much about that turbo. also, what boost are you running?
haha i was reading your list, saw the STi radiator cap and was like
there goes another crappy stock radiator, but then I saw that PWR and was like SWEET!! (yeah, i know i sound like a goddam valley girl, "like totally like sweet!!!"
)
you've got a nice smooth torque curve too, congradulations!! your car looks great (for an RS!! hahaha jk) and hauls some serious ****!!

thanks for the love!!!! The VF35 isn't ball bearing yet it is one of the newest IHI turbos using a divided thrust bearing!!!! it has the same compressor as the VF30 (i think) but has a smaller exhaust side for faster spool up...basically no turbo lag!!!!



how much more power can get out of that? do you have any plans to do any head work?
