Message have any experience with shimming with washers the pressure regulator on the TT oil pump? I did my search and came up near empty on here .

I added three washers to my new oil pump regulator which amounts to 1/4 inch shim against the spring. Not sure how much more pressure that will add to the engine. I want to add 10 - 20lbs more oil pressure. I think Ash said he added 3/8 of inch and the "PeaceMaker" was making about 100 psi of pressure at 3000rpm. Not sure if that is the correct numbers.

I haven't attached the oil pan yet. I can change it anytime the amount of shimming.

Thanks,
