Saleen S7 Twin Turbo

[Anaema]

750 HP, mid-engine magic, super-car handling, 427cid, 5.5 PSI, non-intercooled. its a damn fast car. but i have a question; how in the hell does Saleen get away with an 11:1 compression ratio?

VERY low boost, 5.5PSI is not a lot in a turbo installation, even the Ford XR6T uses 6PSI and that has been knobbled so as not to beat the V8's.
