Racing this weekend I my 20psi OP light went on at turn 5 a couple times. I was doing about 5krpm and my oil was between 1/2 and 3/4 over full. This was a bit of a surprise. I put in an additional 1/3rd quart and the problem went away.
I have the Metric Mechanic scraper and baffle. I’m not convinced that one scraper is clearly better than any other scraper, but the MM baffle is, in IMO, the best baffle available for us. There’s pics and discussion of it in other threads.
Later I’ll look at the data and see what it says for OP.
