Shim for increased Oil Pressure

[in2trux]

I talked with Gearhead allot about this when we did ours. He talked to a Cummins engineer and according to him the internals would take 120 psi.
There is a break point. Seals and gaskets will only take so much.

Do I really want to run that high? No but at 60 psi going down the road I'm comfortable. I never thought twice about oil pressure running a pre EGR CAT.

So why did they settle on 20 psi at idle?
I thank Top Ace for pushing this issue, personally I think 20 is way to low.

Oil is the life blood of any engine, any engineer, farmer or trucker will tell you that pressure and volume matter whether it's a 4 second run with a 10,000 hp top fueler,
a NASCAR engine running 500 miles flat out or a Quad 4X4 tractor pulling a 16 bottom plow. It all depends on application.
