I want my pressure to be 65-75 psi at idle hot and..
What oil temperature and idle rpm is that pressure? And rated oil viscosity?
In my drag race car, I have never seen over 160 F oil temp, and typically it is 120-150 (and that is trying to put heat in the oil). On a street driven car, I believe it could easily be 200+ F and that will change idle (sub 1000 rpm) oil pressure significantly (viscosity vs temp). My street car doesn't have an oil temp sensor, but I can see the idle pressure change after driving 20 minutes.
