In Charge of Snacks
This is my point precisely. For 390 whp we are effectively requesting 480 hp at the crank or, in more critical terms, 127hp per liter. That's a tall order without forced induction. 130 per liter has been done, but not below screaming rpm levels with lunatic cash spent on balancing, oiling, windage, reciprocating weight reduction, etc. Still, I want cams...Oh and on the e92 M3s. I have a friend that had every possible bolt on and tune from AA and he only made 367whp.
