I have used remote oil filter for years on my circle track car. #10 Lines,HV pump and Kevco pan with 9 qts total in the system. Full groved mains with .003 and .0025 on the rods. Engine never ran under 4500 with a max of 6500. After oil was hot 280deg or more It only had 45psi at WOT. Thought for sure she would blow but it never did and took me to a track championship. I will also say that when i put a heaver oil in it to bring up the oil preasure it also made the oil temp go over 300. So i went back to 5W30 OIL. Flow is what u need NOT PREASURE. When i took the engine apart at the end of the season didnt see anything wrong with the bearings.
