Well, of course you are absolutely right, if you increase pressure the
volume will increase.  I guess the bottom line is that you always need to
have more pressure and volume than can leak out of all the bearings,
lifters, etc. at all RPMs and temperatures.

Interesting discussion.   Wouldn't volume increases be limited to the 
passage diameters? And then by the amount of leakage at bearings, lifters 
rockers etc.. Or is it that the leakage points exceed the capacity of the 
oil passage?  Frankly I don't know.

It seems if  you have any oil pressure at all the oil passages must be full 
and then only pressure would increase volume. What I'm trying to get at is 
it seems volume and pressure have to go hand in hand and ultimately aren't 
independent of each other.  But, I guess (excluding the relief valve 
setting) a higher volume pump would ultimately have more potential pressure 
capability also.

  My mental reasoning is starting to seem like the gears in the oil pump. 
Regardless of rotation they keep meet up at the same point.
