This test was done when I removed the radiator and had lots of room to stick a drill on there.
Other test equipment used was a kill-a-watt meter for measuing power consumption, a varrac for fine tuning drill speed and an optical tachometer so I know what RPMs the drill was turning. There was a warm up peroid for the drill and P/S pump and mutiple no-load drill rechecks.
Why would anyone remove the pump and do the test?
There would be no point, it would take a lot more work and the test results wouldn't produce any kind of useable result.
Further back in that post I discribe how I would test it and calculated the max power draw off the engine to be some where around 2 to 2.5hp.
If I spun the pump up to 3000 or more RPMs it could very well come to a point where it reaches 2hp.
