Oil filter bypass

[vette427-sbc]

by your description your oil pressure looks fine.
Increase of 10 psi per 1000 rpm.

However you should be running a higher capacity pan with that higher volume pump. It will suck that 5 quart pan dry at 5000rpm. Edit* Big block HV pump will suck it dry at 4500 rpm.

The only thing the oil bypass does is bypasses the filter if it becomes clogged, it does not create or increase pressure in any way. Your oil viscosity, oil pump and bearing clearances do.

My oil pressure is fine when its not under load... 25lbs at 6000RPM is obviously far from ideal though.
Im thinking that this bypass valve is opening at a pressure way lower than it is supposed to due to a weak or broken spring. This is giving the oil the chance to flow through a perfectly good filter AND this bypass. Thats my my guess as to why it is dropping anyway

I appreciate the help guys
