How much horsepower does a trans am ws6 2002?

Answer 1

Factory rating is 325. People that have run their own dynes on stock engines have seen low 300's at the wheels. While it is way more complicated than making an assumption, for simplicities sake let's say an engine "loses" 15% of its horsepower through transferring power to the wheels. If you say that, then you could imply a rear wheel HP rating of 300 has an engine actually producing 345. Drivetrain power losses are way more complicated than that, but in a simple answer....the engine is rated at 325 but I feel there is enough anecdotal evidence to prove the actual number is higher.
