good numbers man, i just got my 03 gt dynoed today but he weird thing is the dyno told me that my car was putting only 191 to the wheels and 228 foot pounds anyone else think thats a little low even for a mustang. My gt is a 5 speed and has a k&n CAI and magnapacks exhaust

@gottshallsvt Seems quite a bit low to me, runs on the dyno did you make? you should honestly be putting down around the 230 mark.

im in Fayetteville NC and i dont know the elevation here but I took the car to the track last week and ran a 14.2 @98 mph in the 1/4, my car is completely stock including the ford logo mufflers traction control was on and i took off at 2k rpms. just to give ya a heads up

@johnknight1981 Good run, pretty descent for a stocker :)

i have a 99 gt with a kenne bell supercharger , even with the tune i dont belive i would see 175. im not a hater but that is a little high. i made 408 rear wheel hp at 115 mph. in a 1/4 mile run i dont think you would reach 100 mph, it would take a while to reach that speed.

@sinister99gt Not sure what my qtr mph would be, I have never had it on the strip. But remember that was on a dyno with no wind resistance.

@Tj1056 the 03 cobra have 390hp,the GT have 260

[NedacFilms]

@fightingscottish86 It is 260hp at the motor (flywheel), but by the time it gets to the rear wheelsm power is lost through the drive-train, and they put down around 230rwhp (rear wheel horsepower) "real world horsepower"...

Automatics lose even more power than the 5-speed cars.

[fightingscottish86]

@NedacFilms owners manual for my 2003 mustang gt says 260HP stock so i guess it depends on maintenance and octane and performance parts

[fightingscottish86]

@MR01cobrasvt i agree but just a little bit of performance. The GTs are good compared to other cars but there is so much potential I LOVE MUSTANGS !!!!!!! HELLZ YEAH!

[fightingscottish86]

@gottshallsvt hey man u can do all sorts of shit to ur car but if u dont buy a tuner for it then ur not getting your max potential. u can buy a new 2012 mustang and stick a tuner on it before you even leave the dealership and add 30-50HP Ford always gives u room to grow

[MR01cobrasvt]

If you have a GT at least run 91 Octane in it.. It boosts the performance a little especially for a Dyno run...

@gottshallsvt Probably just the dyno.

[NedacFilms]

@gottshallsvt some Dynos run low like that... take it to a Dynojet and you should see 230-ish

[NedacFilms]

@nickma71 and that's a good time for an automatic. A very good driver can break the 13.9 barrier with a 5-speed model.

[NedacFilms]

@Mustang4life321 260hp is the flywheel ratings... you lose power through the drivetrain, so by the time the power gets to the wheels you're going to lose a few ponies. 230rwhp is where these models come in on most Dynos. Some Dynos are high and some are low. I've seen them go anywhere from 220rwhp tp 240rwhp.
