Can you use the 90 deg filter adapter?
Also try removing the oil cooler to see if that helps, if larger lines do not so. You have a thermostat plumbed in?
Maybe oil pump "whipps" the oil like some water pumps do at high revs????
It doesn't seem like your pickup/ pan is a issue.
However; at higher speeds- more sucking- more vacum around the pickup and the pickup glue to the floor. There goes your lower pressure at higher revs.
After all your oil PSI looks OK even if it drops; doesn't seem too low. |
Water pumps are a centrifugal pump, oil pumps are a positive displacement pump, totally different pumping concepts/how they react, sorta like a turbine vs. an internal combustion engine. PD pumps won't "whipps" the oil unless they suck in air with the oil. (I'm reading all the old SBF posting and this looks like something that needs to be corrected for future searching referencing, feel free to ignore this if you already knew pump engineering.)
