...i see Harvey is using Mikes username again ROFL

Like i said i researched and all i am saying is...std comp or 7.9-1 and 32psi held on pump fuel aint gonna cause any issues as the engine is specced to do that.....i will admit the GT35 1.06 on pump may have been pushing the comp too far if i had tried to run max boost but then i remember saying that incar on pump i would run 500bhp and then with race fuel run it flat out Hence why now i have gone T4...the fact is std comp on optimax will run 550bhp reliably if you take the blinkers off...400bhp with blinkers on I aint no genius which is obvious but the people i get my answers from ARE
