We had our oil pump run on Bill Miller's pump dyno. It had graphing capability, the ability to measure pump RPM, flow in GPM, and pressure of course. It also had software to calculate percentage of cavitation at a given RPM. Turns out he was rather impressed with the Peterson R3 belt drive we were using. It moved 43 GPM at the speed we were running it at. Very little cavitation. You might want to give him a call and discuss your needs. Seems like there used to be a short video clip of that pump dyno in use on their web site. Not sure if it is still up.
