993 Oil Pressure

[Jack Olsen]

I just switched in a 993 motor to my 1972 tub after a decade with a 964 in there. My oil pressure gauge is PSI, not the newer style. But I'm hoping someone can confirm that I'm in spec with these. This is all with the engine at 185 degrees.

30 psi at 2000 rpm
50 psi at 3000 rpm
75 psi at 4000 rpm
110 psi at 5000 rpm
130 psi at 6000 rpm

I remember higher readings from my 964 motor, but I never wrote them down.

This is okay?
