Hey Rob;not to disagree with you but I was warned not to use cast or hyper pistons with a turbo by an engine builder. He felt that any kind of detonation would break the piston and cause it to shatter. Even though I would be using a max of 10 psi. Didnt many many factory motors come from chrysler with turbo's and cast pistons? I even think they had a 70 000 mile warrantee.
My plan was/is to build a mild 451 that makes about 550 h.p,which is childsplay yes. Then I was going to use mild boost to make another 150 h.p or so instead of nos.
So maybe the hyper would be too brittle in this situation? I think I'll contact KB and ask them what they think as well.
