319rwhp sounds pretty close... that would be about 370 at the engine, figuring on a 15% loss through the transmission
who said the cat back was going to give him 85rwhp?? NobodySteve Jarvis said:The exhaust will not get him from 315rwhp to 400rwhp. Take it to the dragstrip or dyno if you want to know what it's really making. My guess is it would be around 380rwhp if it was a 6-speed. With an extra 5% drivetrain loss due to the auto, he should still be at around 355rwhp.
Wind resistance in real road conditions sucks down mega horsepower, especially at high speeds.billvp said:you are losing power due to drag
