My oil pump is shimmed about .050". I'm running German Castrol 0W40. On warmer days it is only @ about 50-52 psi at WOT and around 35 psi @ idle once it is warmed up. When cold it is about 60-65 psi @ idle. I do have a rebuilt/forged engine and the crank was polished and standard bearings were used so clearance is a little looser but not by a significant amount. I know the concensus is 7-10 psi per 1000 RPM so I'm not overly concerned. I just would to hear what others might have to say.

Ive always heard 10#s of pressure for every 1000 rpm. Ill have my newly rebuilt motor very soon, Im hoping my pressure will be allright.
