I haven't checked my psi at the filter but at the head @ 3000rpm I'm getting 38-42 depending on the temp.
Last time it was apart I took the relief valve apart and added a stiffer spring, problem is I add new main/ rod bearings (again) at the same time so I cant tell ya if I actually received an increase in pressure.
I'm also running a bypass system that I built, pulls off the second port back on the flange and returns to the plate on the front of the engine.
I used a brass nipple about 2" long and silflossed one end shut then drilled a small hole to regulate flow. My first hole was 1/8" and that was way to large so I re-welded it up and drilled a smaller hole, cant remember at the moment exactly what size
as for increasing pressure, would this kit work on a vw???
It is possible to have too much oil pressure. You'll wash away your crank bearings. In the early 1980's one of my first jobs was at Federal Mogul's research lab in Ann Arbor. I did tests on bearings where we simulated too much oil pressure. The test would eat through the bearing material to the steel backing plate in a few days. It was called "Capillary erosion".
what pressures where you running to get that result?

LOL ! I knew that was an obvious question. I do not recall what the pressure was. Thinking about the test machine, it was nothing out of sight. Since our mechanical gauges top out at 100 psi, I would imagine you would not want pressure near that level.
Well that probably doesn't cross over to our cars then.
In stock form we get 100 psi on start up and run 60 psi consistently so...
