What benefit does a High Pressure / High Volume Oil Pump have to a standard OE Oil Pump? I am looking to replace mine on my '97 Suburban and these seem to be the two options that I have, what difference does the "upgrade" make?

True high volume oil pumps are used on race cars, such as Nascar to pump more oil to the engine in stressful situations. Note that those engines are put together loosely to reduce friction(wore out) to start with and require a lot of oil.
On a stock engine in good condition, a high volume pump is not necessary, because high volume equates to high pressure. In the winter, it can make enough pressure to blow off your oil filter. I know of some 350 Chevies that were rebuilt stock and had a high volume pump installed that spun the rod bearings and locked the engine because pressure got behind the bearings.
Unless the newer pumps have some sort of pressure limiting device, I would not recommend it.

Hello, a High Pressure / High Volume Oil Pump is pumping more oil into the engine and keeps the engine a lot cooler than the OE pump. If that engine has been worked on I would use the high volume pump plus go with a high volume water puimp also.
