    60 psi @ idle and 50 psi @ 3000 is very acceptable, how low does it go @ WOT?

    I don't know how much clearance between the pan to pump and the pan has been cut and made little bigger only on the small end to hold couple more qts but has no tray except what over the pick up. With the cooler i put in about 8 qts 20-50w.I don't know how low it go i haven't been over 4000 rpm.
