good point, are you running standard rods etc ????. also just for ref, turbo technics rate their stage 3 t3 turbo at 285bhp, but that might be running at full boost for which theirs is designed to run which is about 28psi.

if your only going to be running 14.5psi then youll be prob the lower limit of my estimate.........260 ish give or take i reckon. i would suggest you actually try being there for the power run though, that way youll know the graph your given was actually at the boost your cars at when you drive it away.
