I hit 27ish psi around 4200rpm, thats on a standard bearing center section, single ball bearing oughta drop it to 3800... the dyno shows differently mainly due to the boost controller i had on there at the time, with it i was spooling around 5k, with the profec-b it spools at 4200

the other thing you need to remember, I'm also running 7.8:1 first gen pistons, and a metal headgasket, which is probably dropping it to around 7.7 or 7.6:1

My built motor will probably have 8:1 pistons
