My problem is: what do I use for a generator
  that will handle 50 HP or 37 KW.
  Also what do I use for a load.
  I could use 37 one KW electric room heaters.

  Anybody have any ideas?



   Paul,



generators
A good place to start looking is here:

And eBay. Stuff that is not in running condition will be cheap, most people
don't know how to fix'em, most have  IC engine failures, not electrical
failures. But you still need to be able to know the difference to make a
good buy.

Have you looked into renting a load bank? This is a common practice for
power system testing. They are modular so you should be able to pick the
size you need.

I recall when we tested small military generators for Libby some 15 years
ago we would grab electric heaters if the load banks were tied up for other
projects.


Also have a 100 amp 480 volt contactor if you need it - but I figure you
will need more than 1.

Thanks for all the ideas and help guys.
I am going back to the old standby of a prop dyno.
Much cheaper and less tech risk.
