Most oil filters that I know of have the bypass open around 15-20 psi, and a healthy cummins puts out way more than that at start up. So it really shouldn't matter how much a filter media restricts flow, one should get oil pressure at about the same time. If I was rich I would run a stainless oil filter as a pre-filter, a regular filter, and a Frantz bypass filter. I would want the stainless because they flow a lot more and are much less likely to bypass, therefore they'd catch potential debris immediately instead of eventually.
