Dynomometer
(OP)
Is there a way to construct a dyno (for a 5hp engine) using an A/C generator? Looking for a cheap way to construct.

Yeah 2.5HP is even a stretch.

"5 HP motor" (sic) running from a normal 120 VAC, 15 Amp outlet.
There are many examples on the market.

And yes, I remember the first time I saw a SIX HORSEPOWER Sears air compressor. Noting the motor was about a third smaller than the 3HP on my home brew. Then I looked in the cooling ports to see that the motor actually filled only the front thrird of the the actual motor housing to boot!

The tricky thing is to be able to apply a good load to the alternator. What you do is mount it just like a commerical dyno is mounted. And read the torque output. Either with a load cell or scale against a torque arm.
