I think you'll have trouble keeping those heads down at 25 PSI.

i have hit 28lbs with my old pt88

There is no direct correlation with lifting heads and boost pressure.... Its a myth.

JoeNova

You're right, but seeing what he made power wise on 16 lbs, and with his given cubic inches and turbo size, one could possibly draw the conclusion that above 25 lbs his cylinder pressures will be quickly approaching the point where he may lift the heads.

Great power, I am hoping for around 650 RWHP, never got it dyno'ed this year, but winter upgrades should make it more reliable

Honestly, I think that is a little bit low. I actually just dynoed my car recently. With a 370ci, and only a cast S480-1.32, and still through a th400 and 9", I made 888whp on 16lbs. What cam is in it? Maybe it is the heads, as my car has AFR 225s.
