I can see it producing 4 HP at a seriously sharp peak in the power wave, and for such an instantainious amount of time, it just barely lasts long enough to be considered HP. Actual, usable HP would most likely max out at a continuous load of like 1/3 or possibly 1/2 HP, if it's being pushed enough and someone sprays the overload with a fire extinguisher. Any more than that would for sure lock the rotor or trip the overload [W/O fire extinguisher's CO2 applied ].
I would like to see someone try to run a 4 horse pump from one of those motors! Boy, they would be mad! From the physical size, it looks like a 1/4 HP squirrel cage motor. At around 40 PSI, the motor trips it's OL!

My band has a 1000W PA, a 300W Monitor Amp, a 300W Bass amp, a 100W Guitar Amp, and several other peripherals like delays and reverb units that pull about 100W each.
But yet with ALL our devices plugged in and my trusty fluke meter measuring current, I see about 8 amps peak... This is with the signal on the board peaking...and loud enough to split atoms through resonance.
Another question (unrelated)... would speaker cable that is too small (16 gauge)cause an amp (300W per channel)and two woofers (300W each)to blow? This was in a 100' snake, so voltage drop and resistance may come into play here. (8 ohm speakers).
