This is the issue we don't really have much data on whether or not this is normal. With the car running 0w20 from factory we already know oil temp ranges run from 190 to 225 on the street for a stock car. Spirted driving you can expect 230 easily which means preasures would always benin the 40-60 psi range based on your data.
Either this is by design or oversight. But I have to say when I had my 2-3 hour track session oil peaked at 265 with cooler, UOA was perfect.
So I can assume pressures were as low as your and no wear materials in oil.
We just need to get more people involved again. Maybe guys like CSG, Robi and Evasive. I know @
Dave-ROR had logged pressures as well. Lets see if we can get a bunch of data and make a FAQ post.
