Read the suggested material. I have a hydraulic filter sitting right here. It has a Beta 10=2 (10um 50% nominal) the thing is rated at 4 PSID @ 10 gpm of flow with a 150 SSU fluid. Very few oil pumps operate at this rate of flow. I think my HV oil pump is rated at this flow @ 3000 rpm.
My 1um cotton wound filter (yes, 1um) has no bypass and only sees 2 PSID whether cold or hot.
We grossly, IMHO, overstate the interaction of the bypass valve in the vast % of our daily operational use.
When I had my dual Permacool mount on my jeep ..I used Chevy filters (no bypass). I saw the exact same oil pressure on the gauge.
When Bob and Grease did their studies, they used 30 weight oil at room temp. If they had used ATF or some light weight ISO fluid (hydraulic oil) it would have more closely resembled operational conditions. We tend to keep looking at the filter as the end all in the pressure/restriction heirarchy ..when I believe it's more something like an intermediate velocity reduction chamber in a long complex fluid circuit. Sorta like a shop vac ...X gpm in ...large chamber the stuff loses its velocity and comes to a relative crawl through it...X gpm out.
Look at it this way. Let's evolve the circular oil filter just like the circular air filter evolved to a panel filters. Stretch out your 150 square inches of media into a panel. Pipe in your (for the sake of example) pan sump tube to one side ..and your center threaded ID to the other.
How much velocity reduction will occur for all that oil going along a super highway and then coming to a vastly wider set of lanes ..and then bottle necking back on to the super highway?? Remember, it's always bumper to bumper from the time you hit the on ramp ..until you get off.
