89's car way dynoed on a super flow dyno that reads pretty low, His car will put down 420-440 on a dynojet ( I think he is already planning to have it done at VMP). at 8-10 psi. My can also with a wicked conservative tune put down 490/492 (on a really hot day). Im not bashing in ANY way at the end of the day its YOUR car and if you are happy with those numbers great!!

at 7-8lbs around 420 or so. The TQ looks fine and it comes in quick, much faster than mine I think. Im running a custom setup my dyno in my sig was at 8lbs and im running 10 now.

Are you saying in the 3500 RPM range it should drop a bit more into the 11's. Whats is the magic number that is still safe for your air/fuel

The rule of thumb in calculating horsepower is if you double the amount of air ingested you double the power. Since atmospheric pressure at sea level is 14.7 psi, if you run 14.7 psi boost you increase power by approx. 100%. Run half that much boost, ie. 7.35 psi and you increase power by 50%. So a bone stock Mustang that makes 265rwhp should make ~408rwhp@ 8 psi and 530@ 14.7psi.

Dude your car sounds like a **** machine! Please do not blow it up! You are easily one of the luckiest people I know if your rods havent given out yet...do yourself a favor and invest in a forged rotating assembly
