ya I was surprised how quick it was, track was real good with no spin so that probably helped a bunch,.. haven't dyno'd the car yet but when I was talking with the guys at Suncoast who have done another with the identical mod's, they said 620hp crank!?!?.. stock k24's and wastegates, the best I can tell, plan on re-tuning next year to make it smoother and perhaps more conservative for track-use...
can't see it being hard for yours to hit 135 trap

car setup: -250 lbs a28 GT700 kit , rwd conversion 94oct pump , bridgstone 305/30/19 re-11 at 35psi no heat up so yeah tire spinning lol!!

track condition: flat track, 240 feet above sea, 75f, tailwind around 4mph ,pressure around 30 inHg, 70% rh

video link: http://www.youtube.com/watch?v=CS-A6...ature=youtu.be

your input is appreciateAttachment 276120
I'd be happy with this trap given setup.

seeing 1.1 bar consistently(say a 30 degree C day), up to 1.2 bar on a cold day. To best of my knowledge it is a EVOMS/GIAC stage 3, running plain old 94 octane pump. Horrible throttle control/surges especially at low throttle inputs so will probably check throttle-body for gunk build-up then otherwise re-tune it via UMW, EPL, etc...it pulls crazy hard, leaves my buddy's 2011 supercharged 5.0 Stang in the dust, 13mph faster down the 1/4 haha

It's possible. I just checked mine from my last car. I ran 130.76mph@11.39 on stock k24's, exhaust, tune and vp109.


Biggest thing I found is soft rear so it can squat. I dyno'd 420rwhp if I remember correctly.

that's nut! did you add vp109 on different map?you got some ETS before vp109?you guys still on your stock gt2 clutch ?

That is a good mph for your mods and on straight 94 octane no meth. Good job, keep at it, you'll get faster times and better mph.

pretty impressive trap and MPH for your mods. Anyone trapping 130 or more on straight K24's is unbelieveable...

Your car should be very smooth. PM me your VIN number and I can see how old the software is in the car to let you know if there is an update.
