With my industrial motors (out of a bus) I'm looking to replace these two items for saftey as they are cheap. However I can find any specs on the dodge motors. The part numbers are different. The spring for the regulator and the bypass are different (part number wise)

My motor states 65psi relief. If this was the case with dodge motors then I would think, we would see less of the "my oil pressure is high" as it would start to dump to oil pan after 65psi.

Building to make 350hp. While I have the motor in the stand replacing items now. One of those are oil pump, motor runs strong and came out of a bus. While searching I came across that the updated 12v oil pump is what's on the 24 valves and it flow more oil. Didn't say how much but over all more oil.

Is this basically a "stock" high volume upgrade? In gasser world high volume can suck a oil pan dry quick (only 5-8 quarts) vs the 12 we run.

You may want to post this in the performance section. Some of those guys may know more.

My take is with 2.5 gallons of oil and decent drain back galleys as well as the piston skirt nozzles which spray up under the pistons with unrestricted drain down...

It's still only 359 cubes with one valve cover straight overhead, not like a bb chev or ford with valve covers on the slant with 1/2" drain holes at the rear...the front ones don't do much at hard acceleration so I can see some oil starvation being an issue there...Never heard or read anything about the Cummins running dry, plus lower revs etc....
