I've concluded that these discussions are nothing but a frickin' game for you in self ego massaging. Everything I say, which, btw, is based 100% on real physical events, gets ignored and can't be envisioned nor integrated by your mindset and stubborn need to see garden hoses where none exist. I keep looking for you to bring something to the table that falls outside this one dimensional view ..and see nothing. You insist on twisting it back to a garden hose with applied pressure over a variable resistance ..which is not how the system reacts.
You're the ego maniac here on this board ... I can sense it. You can't stand it if someone challenges your "supreme thoughts", and especially if they are right and you are wrong. You think you're always right, but there are plenty of things you don't quite grasp just yet, and frankly probably never will because you really do NOT understand fluid flow physics enough to see through your fogged up thoughts.

Oh, here's where you fail the test 100% of the time.
I've only insisted that a filter cannot alter the flow rate if the pump is not in relief.
You can read that statement, can you not?
How does a pump producing 12gpm have its flow altered? Assuming it is not in relief, the pressures can vary ..but not the flow (again, for discussion's sake assume near 100% efficiency).
How hard is that to see?
This is where you don't get it - I have never claimed that the oil filter controls the flow rate through it. My claim is THAT THE FLOW THROUGH THE FILTER CAUSES A PRESSURE DROP ACROSS THE FILTER EMEMENT. When I say the words "FLOW RESTRICTION" I mean the filter is adding RESISTANCE TO FLOW. It does NOT mean that the filter is making the oil pump flow rate go DOWN ... you ARE ASSUMING THAT for some reason. Hence, this comes right around full circle with my claim (that you don't believe) that IF you put THE SAME FLOW RATE through a HIGHER FLOW RESISTANCE that the PSID across that resistance will INCREASE. Get it ???

Dude ... PLEASE re-read this stuff. See above ... you derailed some time ago it seems. I've ALWAYS CLAIMED that the MORE VOLUME YOU PUT THROUGH A FILTER THE GREATER PSID YOU WILL HAVE ACROSS THAT FILTER. Get a grip and learn how to frickin' read! And I'm NOT going to "hold your hand" and go back to point out every place I've described the physics. Instead, if you're so hot to prove me wrong, you can go back and find exactly where I've claimed differently.

You've found another exceptional circumstance to bolster a flaw premise..
Flow can be altered...
BUT NOT WITHOUT CREATING ENOUGH RESISTANCE TO CAUSE A RELIEF EVENT AT THE PUMP.
This is a way exceptional event in millions upon millions of engine that putt-putt around in ignorant bliss and never see an appreciable PSID event beyond start up.
Don't get distracted from the test results. There was NO relief valve in the test. The pump was turned up until the SAME FLOW RATE was put through each filter, and then the PSID was seen. Obviously, not all filers are the same ... and they CAN have a somewhat significant PSID depending on the FLOW RATE and oil VISCOSITY going through them. And to add (and the reason for this thread), if the bypass valve is not set correctly for a filter's application then the PSID will be high enough to get unwarranted bypass events. This isn't rocket science, now is it?
