what is the max boost, I can get out of a new Precision 67mm P-trim non BB, with 1000cc injectors. Will Soon be upgrading to a 71mm or 74mm. But for now I am 67mm. Also what realistic hp rating would I get with the set up I have, see sig. I have not had car dynoed yet.

What type of gas might dictate what levels of boost you will run. Mine with a 67 GTQ @ 24-26 lbs of boost (on 100 octane "pump gas") made 658 to the wheel. That is with a 6 speed. If I put C-16 in her, I'm sure I would have been able to run higher boost levels safely.

Roughly:
91 octane 18 psi
100 octane 23 psi
104 octane 26 psi
110 30 psi
C16 34-35 psi if p trim will flow this high. I have between a Q and R trim spssgt850w and have gone up to 34 psi and hp was still going up ~9 hp per psi.
