dynoed my GTP

[bayareagtp]

i only have horse power and torque specs . i am not sure if they knew what they were doing for a automatic it took them 2 runs to get the car to stick in 3rd gear for the dyno so hopefully this is correct . i think it sounds about right . the dyno machine was a model 248 . anyways hope this helps everyone out that is trying to figure out their own horsepower .

215 whp and 238 torque .

I've dyno'd my car twice now. I always had them dyno in 2nd gear and take it to 6K, per DuBob's recommendations.

Nice numbers! Still on stock pulley?

3rd gear will show the most accurate dyno. 2nd will show a slightly higher number than third, but it's not as close. Getting it to stick in gear can be kinda tricky though....you have to feather it, and then turn on performance shift when you are sure it can't shift down anymore.

Was it a Mustang dyno or a dynojet?? I did 215 on a Mustang dyno which shows about a 12% lower number then dynojet and I scored a 215. Stock pulley.

I think after the first pull, the operators that pulled my car in and were chuckling kinda shut up. :th_laugh-lol2:

yea those #'s are with the stock pulley and the mods in my sig. . i wanted to get a base line . next dyno will be with a 3.5 pulley , plog and crossover pipe .
