Can someone tell me how much
oil (%) is bypassed when the
oil filter bypass opens?
I noticed that a lot of filters have what I would consider low bypass relief. We run 35 to 70 psi on our street motor and the filter opens at 8 to 11 psi.
I took the second
oil filter listed as an example from Summit. I did notice the first one was a K&N with no bypass. Nice, I'll have to check into that.
