Is this a block mounted filter or does it have a remote mounted filter? If it’s a Ford filter it makes me think it’s a remote setup, but could be wrong. If remote is it possible there is another restriction in that system to at is driving pressure at the filter up? I’m trying to picture it in my head but if there was a restriction in the output line from filter to engine then that would increase pressure in the filter right?
As others have mentioned already I have also run the Wix Racing and at times the Fram racing filters on circle track cars that would see 80 psi cold and had no problems there with plugged bypass in the adapter. These generally don’t filter as fine as a street filter but they do flow more easily through the media.
edit… one more thought. Did it do this before or just after you put a new filter on? I know you said you did a full turn, have you tried going a little more? In theory it shouldn’t need it but maybe try another 1/4 turn or so? Also did you libe the gasket so it doesn’t deform when tightened, I assume so but thought I’d ask just in case.
