Dan Duncan had gotten up past 13,000.  He said he was balancing his
engines quite a bit tighter than the factory did it.

Consider the source :-)

The problem is not balance. It is centrifugal load on the rotor bearing.
That is why we run 150 psi oil pressure in the TTC engine.

What's the story about Dan Duncan and the doctor in Oklahoma ? Never heard about it.

Steve Carlisle

I don't have all the details but I think he was convicted of mail fraud and then
disappeared into Mexico I think. Many years ago.

Wow! What a sad story about Dan Duncan -- and we thought testing
the rotary engine might be dangerous.
