driving a supercharger

[rbohm]

mild cam with turbocharger? i just spent an hour reading though old posts, and looks like a short-overlap cam with same duration exh and intake is the way to go? any of mike's cams better suited to turbocharger?

sounds like i need to decide if i'm going turbo before i rebuild my bottom end.....

8) the reason you want to minimize the overlap with a turbo is because you want to build cylinder pressure at low rpms due to lower compression ratios to allow for boost pressure. lower valve overlap tricks the engine into thinking it has more compression than it really does. this doesnt hurt at higher rpms under boost though as at that point your engine can handle the higher cylinder pressure before getting into detonation. do however limit ignition advance though, and control your boost pressure as carefully as possible.
