10psi would need a tune for sure, probably a bigger fuel pump. Stock MAF would probably run out of flow resolution which is why I think they limit it to 7psi with a stock tune/ tune limitations. Centrifugal works well on the n/a ecotec because its gentle on the bottom end because they dont start to create boost till about 2000rpm (raptor) which means you dont get the high cylinder pressures at low rpm like you do with a PD style blower.So I've decided on getting a Centrifugal Supercharger kit and I was wondering on what I'd need to change in the car for it to run 10psi. The Raptor Supercharger kit states that no tune is needed with 7psi but how much more power would that produce as opposed to 10?
Would forged pistons/lower compression ratio and a different crank be necessary? What would need to be done to the ECU, what else is not necessary but would be good to add on? And the 4L60E is rated to handle 450Nm, would 10psi exceed that amount considering the L67 develops 380Nm at 6psi?
Thanks guys
