Dyno numbers in, a little disappointed
After working on this car for a year now I finally got it on a dyno. It is a '01 GT w/ a '98 4v engine and a T76 hellion kit. It's been bored .020 over, mildly ported heads,Diamond pistons, Eagle rods running stock compression. It put down 460 hp and 513 tq. at the rear wheels on 15 lbs. of boost and 93 octane through a 4r70w tranny. I was really expecting more power out of it though. Any suggestions on what my next step should be to make more power without switching to race fuel? I'm thinking maybe some shorty headers would help since it still has the stock manifolds and next some custom cams. It will be a while before I do any more to the engine though because I have to get the rear suspension done and get my converter re-stalled first.
