If you put together an engine that will suck the pan dry with a HV pump.......you put together a stupidly designed engine. Because that engine will lose oil pressure at high rpm with standard or HV pump. Either there is no oil in the pan to supply the engine or there is insufficient pump volume to keep the pressure safe. I use a HV pump in every engine I build and I oil the timing chain. Never sucked even a 4 qt pan dry and never lacked for horsepower. I like the extra volume potential.
I'm wrong. Pittsburghracer is wrong. Maybe we should go to a dry sump system in the engine because both other pumps are wrong.
As to my question.........At the same oil pressure with the same oil you cannot pump a greater volume through the engine with a HV pump.
If you use higher oil pressure with a standard pump than a HV pump, on the same engine, you are pumping more oil volume through the engine with the standard pump because you are pushing oil through the engine clearances under greater pressure.
