Stock rwhp and rwt for an '04 GT?

[GregGTStang]

Does anyone know the stock rear wheel horsepower and torque for the 99+ GT? 5 speed...

My wife's '04 GT put down 245 hp & 284 TQ with 4,000 miles on it. We have Offy X-pipe, Welded in MagnaPacks, & Accel Air filter with removed silencer.

that's with some mods....did anyone every do a 100% stock dyno run?

 

[Ryan02Stang]

usually in the 230's for horsepower. and 270s for torque

 

[trinity_gt]

When bone-stock my 02 put down 228.5rwHP. Torque was back calculated to be 272.5.

 

[decoy562]

Horsepower on average=220's to low 230's.
Torque= 270's.

My tuner told me that most stock '99-ups that he has done put down 225-230RWHP. Thats on a Dynojet if it makes a difference.

yes it makes a difference. The dynojets put out higher #'s then the mustang dyno do to the fact that the mustang dyno takes weight and some other things into calculation.
