It has been a frustrating 7 month, trying to get the single rotor
dynamically balanced. After a lot of fellows on the lists trying to
help, I called Mazdatrix, and as of last week I got the parts back from
them balanced. The engine is going back together right now for
continuing testing.
The main effort is now designing and testing the [p-port] intake and establishing
a performance baseline.


I made some changes on the outside of the engine. For example the lower
engine mount points are now on the front of the engine to provide
mounting areas for radiator and oil cooler. The location is much like
with a Shertz Beam on the two rotor.
The third mounting point is on the oil pump cover at a location similar
to the 12A front mount in the car. I don't have pictures yet, but the
castings should be here any time now.
I am also working on getting a magneto ignition in.

The e-shaft in the picture was taken before hardening and grinding. The
cooling oil jet location is clearly visible in the original location.

I hope to be able to do shorter update intervals in the future.

Thanks Richard and thanks to Dave Lemon at Mazdatrix.
I think this engine will eventually be good for 120 HP at 7500 RPM.
That will make its power to weight ratio more than competitive.
