Question type: General

I have a 2000 firehawk TA 5.7, any idea of
the horse power? People always ask and I
say around 400. Am I living in a fantasy
world?

The Trans Am 5.7 V8 rates 305 hp, but with the WS-6 performance package, revs up to 320 hp. Not the 400 hp you say, but not bad either, if you have the WS-6 version you can hit 0-60 in five seconds. The source for the information comes from my Pontiac Service Manual issued by General Motors and revised August 2000. Hope this helps.

Old lumpy spoiler, and I too have #250/741 slp firehawk. All I added was stainless steel long tubes. N had it dyno'd and tuned. = 323rwhp with 336 rw torque. ... which if it were bhp ( engine hp ) it would be in the area of 420 hp 435 torque at crank. Which is quick for a basically stock car from factory
