more than 215 i would hope because i raced a guy i know in his 2002 lexus and specs on it show they have 215 hp i dont know about the torque though..i know its bad to race but he never would leave me alone
The only way to get the exact numbers, would be to put it on a dyno and stop your guess work. You can have two stock 98 GT's, and on the dyno they'll give you two different numbers. It all depends on how well it was maintained, and just how many miles on the clock. If you were close enough, I would put you on the dyno just to get your numbers, Mike. SCT Tuner.
225 is the base for 98 at the engine. 265 is for the PI cars. Like theyve said, to find out your actual wheel hp youd have to toss it on a dyno.
(Oops its 225 for 98 not 215)
Thats at the crank. so dont be suprised when the numbers are lower on the dyno. I think its like 5-10% loss through the drivetrain.

They will vary but the official reading is 225 (up from the 215 of the 96-97's) and 285 on tq (same as the 96-97's). I think it is said that a slight exhaust tweak allows for the extra hp. As has been said, the best way to find out for sure on yours is to strap her to a dyno. The mods are good engines even in first generation form but higher mileage examples will be a bit tired and won't show factory numbers.
my 98 GT mostly stock, just exhaust and intake put 222 to the wheels. with heads and cams and a few other small mods I put down 305RWHP! Also depends on where you are! Temp, and humidity can play a big role in performance (San Diego CA.)

-1998 Ford Mustang GT (4.6L 2V V8 Automatic, PI Head Swap, 4:10 Gears, 78MM BBK Throttle Intake, CAI, Flowmaster American Thunder Catback Exhaust, A/C Replacement Pulley and a tune.) Summer Car:kooky: Ran 13.84s 1/4 mile with street tires.
Definitley get a dyno tune for your mustang.
I belive a 98 GT stock rwhp numbers are more like 190-200 rwhp
and 230-240 rwtq but,every mustang is indeed different.
Dyno your mustang and find out where you are at!
