Re: Oil pressure, oil temperature and water temperature sender units question?

Most SBF run a mininum of about 20-30PSI at idle and a maximum of about 70-80 PSI at full song (relief valve usually opens @ about 70-80PSI). Your 40-45 seams OK to me. When you get it up to above 3500-4000 RPM you should be about 55-60 ish.
