wow thats surprising... you should have way more hp that that...
nope not at all... thats a bs myth. It wont hurt you at all, you just wont use the full 75mm unless you have heads and cams, N2o, or FI.does anyone think the 75mm is robbing him?? pretty good numbers...i would have though a little more though....do with headers and mid pipe next...you will see nice gains with that...
