Hi volume oil pump vs standard volume pump

I got a few pump questions for y'all. I understand that all things being equal on an engine a high volume oil pump will produce a higher pump pressure as well.

On a rebuilt engine with a mild hop up with stock bearing clearances and maybe a 5,500 rpm rev limit is a high volume pump necessary? Does a high volume pump and higher pressure it produces actually hurt horsepower with its associated drag on an engine like this?

I can see a higher volume oil pump being used on a higher revving higher HP engine to protect its bearings, or in one thats got enlarged bearing clearances because its worn out and the high volume pump is being used to somewhat extend its life a bit.

Anybody else have any other facts on this? Am i off base with my thoughts on this?

Thanks
Matt
