230/224 .576/.563 111LSA=2 much cylinder pressure for boost? Just curious as to how much boost I can run with this cam. In the interim I wouldn't be running more than 4psi w/ a turbo......after I drop the compression via 6.0L heads I'd consider a smaller cam.
Thoughts?

Re: 230/224 .576/.563 111LSA=2 much cylinder pressure for boost? I don't think the cam's going to be your limiting factor...aren't your heads milled for higher compression (11:1)? 91 octane doesn't give us allot of room for error either. You're probably better off waiting for the heads and swapping everything out at once.
On a side note, that cam is on a 112LSA, so it's got a fair amount of overlap...you might get a decent amount of blow through (which will limit the amount of boost your cylinders will see). I can't image that's much fun to tune though.
Again, just do everything at once and do it right. If you blow your motor now, you won't be back on the track until the spring/summer of next year...and we all know how much fun 100+ degree track days are!

Re: 230/224 .576/.563 111LSA=2 much cylinder pressure for boost? I'm at 10.8:1 compression....and the cam is on a 111LSA.
Thats why I was going to run only 4psi until I drop the compression. I guess I could always put stock heads back on.
