Need some help - loosing oil pressure at high rpm's

[madmaxx]

Interesting i have alot of thinking to do it should pump the volume!!!! What do you mean by changing out the spring. The one in the oil pump. It has an adjustment and I did turn it in about 3/4 of a turn. I could have gone a lot further. To be honest I don't know how much it was engaged until I turned it in. So if the pump Rv is theoretically reset to 80psig will that solve the issue? Is it possible the pressure drop across the cooler will just grow with higher pressure/flow and never supply the engine.

As far as plumbing standard superformamce an 10 hoses and fittings identicle to my last one. My last one had a 7 psig drop across the cooler(stock SPF) I have a lot of data from my oil filter experiment a couple years back. By the way on this one I use 3.99 ford fl1a from walmart with Mobil 1 10w40 high mileage ( extre zinc/phosphorous.)

The fix = make a more efficient oil circuit, or change the spring in the pump. I have always ended up changing the spring.
