What about jet type boat prop?  A friend and I kicked this idea around about a
year ago.  You could bypass around the prop to get some load control.  There
are variable pitch models as well.  You need a water resovoir but an above
ground pool with appropriate baffeling could do the trick.  We also thought
that a houseboat model would be cool.  We'll build the dyno room on the boat
and go to the local lake.  We could butt up against one of the bridge pylons
for a test session in between cruising the lake.

Jet props are wonderfully ineffeicient and it should be no problem to get one
to eat 300 to 400 HP.  The pool might boil after a while but the lake would
provide a near infinite sink.
