I am saying that with a 5 qt. pan and a hi volume pump you are sucking so much oil out of the bottom of the pan and under hard acceleration or hi rpm's.Another thing to think about is the extra load placed upon the dist.,gear etc. trying to turn the hi-volume pump.
Also where is the extra oil going to go?
It is also limited by the other oil passages in the engine.
If you don't mod. the oil passages "up-stream" what is the point?
A hi-volume pump is not required for any stocker style re-build.
I would never run a hi-volume pump un-less I had a 7+ qt. oil pan with all the baffles and trap doors in place.
In a 5 qt. pan how many qts. of oil do you think are in the bottom of the pan when he is turning 5,000 rpm's with a hi-volume pump?
How many qts. are trying to be pushed to the valve train and other oil- galley's?
P.S. Denny no one said you don't build engines.
