As your engine RPM's increase, the stock pumps flows more oil in a reasonably
linear output (based on RPM) until a point
of cavitation. Your bearing clearances remain constant, therefore your oil
pressure increases relative to RPM.
A high volume pump moves more oil at lower RPM because of the

I to like to see higher than 7 PSI at idle, but most race engine builders
insist this is enough.
If they do, they're nuts. :-)))
I prefer a minimum of
