Sorry if this has been kicked around before but I couldn't find anything in the search.

My oil pressure runs 75 to 80 psi using mostly 40 wt oil right now. Oil temps ran at 230F during my last flight at 8000' flying sportsman which I thought was high. The oil pressure drops to 20 psi and returns to 80 in about 2 seconds when I roll inverted. Should I lower the pressure to get better cooling?

Cooler is mounted on the baffle and engine is o-360 with the ps5.
