For 370 rwhp...the car should run a LOT quicker than that. That body style car isn't light, but they aren't all that heavy. A buddy of mine has a '02 GT with full exhaust (longtubes, off-road h and one chamber flows), and 4.30's, and it's a 5 speed...ohyeah...he has CAI..and, he's trapping 103-104mph..on Nitto's...launching easy. And, his car should only have 255-260 at the wheels. With 370 at the wheels..the car should go 11's easy, at..I'd say 112-115 with ease. Are you running sticky tires? What are you launching at? Also-Do you powershift? I am a strong believer in powershifting...when my '91 GT was on it's stock motor, I went from [email protected], to [email protected] by going to 17" nitto drag radials, and powershifting the hell out of it. The car had 150K+ miles on it, and the only mods were longtubes, and cat back and 3.55's. Not bad, for a car set up for the twisties

I am launching at 4500 sometimes 5000 depending on track conditions. I am not powershifting I am afraid of breaking the transmission. I am also running Etstreets that are 11.5 inches wide (I know that the tires are slowing me down about 1mph.).
not powershifting is whats killing me.

IMO, your power level is down also. How much boost are you running?

With 339rwhp, I trapped around 114mph inn a 3370lb car with me in it.

id say you'd break the transmission faster with the et streets then really powershifting the car.

not that my car is as heavy as yours but when i had 340 rwhp i was trapping 113 consistantly
