Want to reduce oil pumping losses? Here is how I would do it.

1 like mechanic said, reduce the relief pressure on the pump.

2 intentionally put an undersized oil pump on the engine and an additional electric oil pump. The electric would run when the engine is cold and below a certain RPM so you don't get near 0 oil pressure at and near idle.
I almost did this with my suburban when I rebuilt the engine, put the undersized factory non-turbo oil pump back on the motor and back it up with and electric but I couldn't find an electric oil pump and filter I liked.

How about just put the biggest oil filter that will fit on the oil filter head?
