38r with a 1.15 housing and hybrids I was pegging a 40# boost gauge and looking at 70psi drive pressure... Be careful unless ready to do studs...

And that was with PMR's...

What that means is the boost was WELL above the 40# gauge... closer to 45-46 I would guess... Drive pressure may have been 66-70... I was kinda busy...LOL

im assuming you have studs. and with the 38r and hybrids you only made 402hp? I thought it was to be in the 450 range? or were you detuned to save your rods?
