Oil system myths

I don't agree on #2 or #3.

#2 - if you suck harder on the same size straw, it will pull more delicious (and less white) Coca-Cola into your mouth. So if you suck harder on a 3/8" NPT hole, you'll pull more delicious oil.

#3 - the HV pump will typically (not always) come with a 70PSI spring. The standard pump, 55PSI.

#2 - really important if you still run some 50 grade oil. Or you have the RPM up. Or both.

The number 1 biggest increase in gerotor oil pump performance is a bigger inlet. Always. That and a pan with more than 4 quarts in it.

You can’t get the pickup tube too big. We are lucky today because I can run a 0w-20 oil in my junk and make as much power as I want and not have issues. That 20 goes up the pipe much easier than a 40 or 50 or even a decent 30 grade oil.

That does take some load off the pick up. You can only get the gerotor to pull X amount of depression. You can’t necessarily make the pump “suck” harder on the inlet.
