Dwight and CobraEd have hit the nail on the head. Pressure and volume are two different things. You want more volume but not pressure. It's the pressure that is hard on the gear. I have run HV pumps on everything for years without problems but have always made sure the pressure is about 65 psi max hot. HV pumps keep the pressure up at hot idle which is a good thing. I would like to hear more engine builders thoughts on this subject.
