Oil pump help - how to Increase pressure?

(1/3) > >>

luvemfast:
On the new Race motor, the oil pressure is VERY low at idle. To the point of the warning lights coming on, under 15psi.
I'm running the turbo pump, it's is meant to be higher volume.
I can recall reading somewhere that you can shim a spring and that alone, increases the pressure.
I've done a search, but can't find it.
Any help?

peter mc:
well simon u ask your engine builder

luvemfast:
Well, Peter has informed me that the shimming of the spring only increases the peak pressure.
The spring is part of the oil pressure relief.

The main issue is I'm used to stock engines. And this one is far from that.
Peter has suggested that I increase the idle closer to 1,000rpm and connect an actual pressure gauge and see where that takes us.

Peters very right, but it dont matter stock or race engine engine is still turning the same rpm, was the oil system primed and checked for presure prior to starting it, oil light only means 1 thing,  no pressure, or the tolerances have somehow become greater than they were when the engine was built, keep us informed, fingers crossed its a lazy oil light switch

Roberto:
What oil grade are you using Simon?
