Left side - oil pressure at oil filter housing. Right side - oil pressure at Mains Gallery. Using this example, the oil pressure at the Mains Gallery is ~85psi @ 80ºC. This is acceptable. But you'll need to check the pressure when you're pushing on the track when the oil temp is 120ºC. I wouldn't recommend less than 70psi at the oil filter housing at any temperature or weight oil. This was done with 5W30.
