Any pump can be made higher pressure, but only at a higher engine speed, by changing the relief spring.
A HP or HV regulated pressure can be set lower or higher for the MAXIMUM pressure.
The HV pump WILL deliver more pressure to the engine progressively up to the regulated pressure because of the larger gear set.
A high volume pump takes more power to turn, so wears distributor and cam gears faster.
10psi per 1000 rpm is still a good rule.
OIl flow though the bearings is more important than
oil pressure.
A tight clearance engine with a HV pump and thick
oil is a bad example.
