    Depending upon how hot. Normal driving 45-60 psi
    Coming off track, 30-45

    Of course I live in Texas and it’s hot with a side of hot here, so my temps tend run a little higher.

    Waking this up.

    I'm measuring oil pressure at my oil cooler sandwich plate vs where the factory measures it. I don't know which port I'm measuring from, if it matters.

    Right now I am seeing 15 psi at idle hot.....

    15 is OK if the oil is very hot, only at idle. This is mentioned in the 302S manual. Usually coming off-track, hot idle will drop under 30 PSI, usually I see around 20-25 hot idle after a 30-45 mins on-track.

    Same. Almost never below 30 PSI
