150 HP turbine here.  Not a lot of power and virtually no torsional
variation.   This should be a minimal test of the gear drive, not worst

Good points.

30K RPM ???

If this is the turbine I think it is (saw it at Osh) , it already has a
built-in reduction with an output shaft speed of 6000 RPM, just right for
the Ross. At 30,000 the Ross would soon self distruct.  The Torrington thrust
bearings are at their limit at 6000.
