Horsepower
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.
At the crankshaft your probably right around 400hp.At the rear wheels I'm told 337 hp. I'm owner of 2000 firehawk trans am with ole bumpy spoiler.
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
No you’re a little high but the LT1 firehawk is 340hp per the hood decals but I but the Fram air filter and a little booster I get about 365 horses mine is a 1995 car number 0315
