Pretty cool project. Any idea what kind of power you can absorb? Can you actually get to peak power?
I have two methods to measure fuel consumption. The first is the megasquirt data... certainly very convenient but not completely reliable.

The second method is to run a fifth fuel injector into a vessel and at the end of a test the vessel would be weighed. The results then multiplied by four for total fuel consumption. The fifth injector would have its own driver circuit so it wouldn't load down the engine injector circuit.

The hydraulic portion of the dyno was originally intended for marine engines and can absorb 200+ HP. I had to change the pump and a few other things
but I suspect the dyno is still capable of absorbing 70 or 80 HP.
