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

[madmaxx]

I agree with the oil cooler they are useless but look cool and sell cars!! Surprised by the rp statement. My shade tree mechanic analysis indicates different, lol. The analyses rp performed showing flowrates vs pressure drops at 30cst were pretty thorough. To boot not that it matters in our world they filter to 20 micron at 99% efficency. I have cut them all apart and I know the rp uses synthetic media, not sure about the fl1 hp. I also know on same set up the rp worked perfect and I had 2 psig more pressure at 5500 rpm going down the freeway over the fl1 hp.

As far as the pressure drop lets see what happens with the filter change. The previous owner been driving like this for 4 years and 4 k miles with zero ill effects. I am 100% confident this spring been in their from beginning as builder dyno showed 58 psig now we install in car take with oil cooler and he has been running 50 or less since new.
