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.

That's truly sad about what happened to Dan Duncan. I really, REALLY
hope bad karma came back to that Dr, in a truly massive way. He
deserves it.

Dan G, I don't know why you are sticking up for Duncan, but be aware that convictions are based on evidence.  The "sad story" is what he did to his customers.

Don't feel sorry for Duncan, The Dr. was the good guy.  He was not alone, if I recall, he was working towards a class action lawsuit since there were many of us that were screwed over by Duncan.  It was fraud.  Duncan took thousands (in 1980s dollars) from me and my Dad and sent us nothing but a brochure before he ran away like the thief he was.  We sent letters to Duncan and had phone conversations, "your engine will ship next week", or "oh it's on the dyno", it was all BS.  Talked to one customer that was local who went to his place and took possession of a half-assed engine in a partial state (better than nothing) before Duncan split, he was glad to get that and did not get what he was promised.  Duncan=pant load.  Avoid this guy like AIDS.
