94 Z28 with moroso cold air, BBK headers, Borla exhaust, its a 6 speed if that makes any difference

 

No way to answer that for sure. You should find a chassis dynamometer somewhere near you and get a objective measure of it rather than relying on guesses.

Could be as much as 280 to the wheels and as low as 260 with your mods. We can guess what you MIGHT have but we can't tell you exactly what you DO have.

 

260~270 rwhp is my guess. Chris 96 WS6's response is more appropriate though....

 

Isint stock HP advertised at 275?

 

Im not to sure, but that rating might be at the motor, not at the rear wheels.

Yes stock is 275, but that is for the motor. Wheels is different. He is probably making around 270 at the wheels with his mods. That would put him around 315 horsepower at the crank.

 

My 96 stock without those mods was 267 hp 300 ft/lbs at the wheels. I'd guess 295 hp 310 ft/lbs

 

I'm guessing 270-275rwhp and 300 TQ.

 

my guess is 265-275 the cold airs do wonders for our cars
