   I agree with you.  I still feel that the best approach is the large
   diameter e-shaft concentric TC.  Once the bugs were worked out of
   that, then a custom casting integrating the redrive, starter/
   alternator combo could be made and that would really boost the power
   to weight ratio advantage that the rotary already enjoys.  I wish I
   had a billion dollars to pursue such fun.

Since the rotor gets to two TDCs per revolution, (three crank
revolutions) wouldn't a properly ported  single housing produce the full
two rotor displacement per rotor revolution? Off  of full throttle some
exhaust could be inserted into the compressor to reduce noise and allow
very lean mixtures. The compressor end of the two rotor would operate at
much reduced temps, and could have aluminum for one of the side plates.
Or, the front plate and say half of the center plate in aluminum with
just the rear iron as 100% stock.

Or, rather than blow down one side of a housing, blow down both sides.

Or, Blow down one side and use the other side as the compressor.

Or, have a very small two rotor used as the compressor, blowing down one
side of one housing and using three sides as the compressor.

Or, blow down both sides of one housing and use the other housing as the
compressor. A toothed belt would take power back to the Mazda engine. in
the case of the small rotary scheme.

Felix copied the drawings of a truck air compressor. It was a compressor
first.
