Haven't post much lately, so heres a question.



I have a rotor pump, before I did any modification to it, at idle, I get about 10psi, 30-40 at cruise, I think thats within specs from the factory service manual, but I think its a little low, so I put a bunch of washers between the nut and the spring of the oil pressure regulator valve on the oil pump, now it idles at 25psi hot and 55-60 psi cruising.



but the thing is, with the washers in there, it limits travel of the regulator piston, I dont know if it will affact anything, but so far I haven;t have any problems.



what oil pressure you guys have in you Ys? do you guys think that 25psi at idle and 60 at cruise is overkill for these engine? is there any high pressure springs out there that will fit the rotor pump instead of putting shims and washer in it?

Those pressures are REAL good!  What are they cold?
