Mine is about 55-60psi when cold idle dropping to 31/32 at hot idle ( 80 deg C plus oil temp ). Drops a couple of psi when fans kick in. That's on Silkolen Pro S 10W/50.
It runs slightly higher oil pressure if I run Castrol RS ( or Edge ) 10W-60 but there is a reason for that to do with the oil molecules
