Oil pump thread
 

Theres standard pressure
High pressure.
high volume,
high volume, high pressure

What would a fellow want that has spring oilers (16) .040 orifices stealing about 15 psi of pressure and volume?

10778 is what I've put in a few bigger power engines. Stay away from the anti cav, I took an engine apart that had one, kept having low oil pressure problems at idle. Bearings looked pretty good though.

10778 that,s what i run.

Mike you shimmed your pump or something right?

Along with spring ollers I also have piston oilers, so I run Titan pumps. They are adjustable to whatever pressure and volume you require.

yes,a thin shim behind the spring to increase the pressure a little.i have a oil pump dyno so i know what the pump is doing before it gets installed.

This is what we do to mine also, I have 75psi cold idle, 40 psi hot, I am a fan of good pressure and volume, one set of engines I did years ago I had standard volume and pressure, wiped mains in both in 3 hours.... after redoing with HV and shimmed pumps I never had an issue again.

How about the billet aluminum pumps? I really like them. I think I would want high volume with spring oilers.

depends on the oil pan...have to be careful on some high volume pumps as they can pump the smaller capacity pans dry...

Has anyone tried the CVR OPS45? I like the idea of the adjustable pressure, even though I'm not sure how your supposed to adjust it.. What kind of pressure are you seeing with the 10778 in a big block? I've got a 14qt pan so I'm not worried about sucking it dry. Ide like good pressure and volume though because I plan to run hard!
