Precision oil pump he deals will this all the time from cobra guys. He will give u the guidance u need.
(yes i am referring to the spring in the
oil pump.) ideally u would want to improve the efficiency of the
oil circuit (shorter lines, bigger hose, high flow cooler, etc.) but if that is not a direction u want to go then change the spring so that the pump will bypass at a higher pressure. Its a cheap simple fix. I have not seen the pressure drop increase. good point though. Let us know what he says.
