What are the stock dyno numbers of a 99-04 gt????

GTRACER88

Mine dynoed at 222 RWHP and 232 FTLBS of torque, in an automatic.

Adam03GT

Dynoed stock when i got her at 238 rwhp and 249 torque. Automatic

good numbers would be around 215rwhp - 230rwhp and 260rwtq - 285rwtq

these are just guesses.. take out 15% drivetrain loss for manuals and 20% for automatics.. that will give you a good estimate

My manual stock was 232rwhp/268rwtq

Great thanks for the quick replies guys. Just interested in the stock numbers. Our 3.8's are typically around 160-170 at the wheels but some of the new work I'm having done next week should put me around 190-200 but I'll need a bit more if I'm going to keep up with the 4.6's ha ha.

After my t56 swap, it dynoed at 236/274(jlt cai), after a mailorder tune from vmp w/91 oct I got 244rwhp/286rwtq(jlt cai/tune). I'll be taking it and having it dyno'd again after I receive my commando delta tuning program.

My '01 Bullitt dynoed 247 stock, can't remember the torque, I'll look it up when I get home.

WOW!!! some of these numbers seem quite high for stock cars. My car dyno'd at 225rwhp and 281rwtq and people were saying my numbers were really high. So i would say about 220 rwhp would be an accurate guess on average. With exhaust, easily over 240rwhp and tuned would put it over 250rwhp. So thats about where you would need to be to keep up with a relatively stock GT...especially because our power is made higher up than you and we have about 800rpm more to play with than you do with the same gearing and transmissions.
