Since there is a formula to determine how much power is required to turn the pump a given rpm, the goal is to make that amount of power, at wot, at that rpm.
It doesn’t really matter if that’s the engines peak power or not.
As long as the pump load and the engine output are equal at wot, at the desired rpm....... that’s as high as the engine will rev.
Right, but then you've built the wrong motor if the peak hp is at much higher rpm.
