There are ways to do
that, Greg.
But, Al had his 20B
on a dyno and could probably give you some “real world” advice on load
settings.
Al??

Loads
Finally in the dyno room building the
mount plate to begin testing. Tracy says that the engine should be tested
with the prop on, and this is kind of hard in a dyno room. We are
mounting the engine without the PSRU, so that we don't tear it up in testing,
and instead hooking directly to the shaft which is loaded by means of a water
brake. We can put any load on it that we want, problem is, how to
calculate that prop load in foot-pounds, at different settings. Talked
to Craig Cato, and he is leaving for Europe,
so doesn't have time to run the calcs, and I am just a dumb high country
nail-banger. Any thoughts?
