How much Horsepower?

I have a 98 Z28 M6 with QTP LT headers, functional SS hood and air intake, LS6 intake manifold, Magnaflow True duals 2.5", Magnaflow X-pipe, high flow cats, ported stock throttle body. I was just wondering how much horsepower i am making to the rear wheels?

Stock: 290ish rwhp
Hood + CAI- 5-10rwhp
LTs- 20-25rwhp
LS6 intake- 5-10rwhp
TB- 5rwhp
Exhaust- 15-25rwhp

Sooooo....340rwhp or so would be my guess.

I made 340rwhp and 356RWTQ with Lid, Pacesetters, ORY, through the flowmaster catback. Thats a 2001 SS M6. Its so hard to tell cause every car is so different. It shouldnt be too far off what they said above. If you get your car dyno tuned you should squeeze out more than you have now. I got 23RWHP from my tune alone.

i would say your right. This is a 98. So the tune is horrible It probably has at least 4 degrees of knock at the top end. The heads are horrible. so around 330ish. I looks like your on the right path get some goods heads and a decent cam then you'll be surprized. You'll wake the car right up.
