I had to get rid of the Mazda parts as they got in the way of the 750
CFM Holley.

A few more days work on the intake and the 3 rotor turbo compound could
run .

I need a Holley leaning block.

Amigo --
   I am completely unqualified to comment on any of this except to say
that it's looking very impressive and, I would guess, you're thoroughly
enjoying yourself with the project. I wish you all the best for a
highly
successful result as measured by a mind-blowing BSFC.

It will be because 50% of the waste energy suitable for  recovery is
dissipated by the exhaust valve.
Curtis Wright discovered that back in the 1940's and 50's.

The  rotary has no exhaust valves.

That puts Mazda in a unique position to build the most efficient
gasoline engines in the world if not more
efficient than even diesels. Eventual, with a few improvements, like a
variable area turbine nozzle and a
variable ratio turbine gear box it could exceed the efficiency of
even a
turbo compound diesel like the Detroit Diesel
DD15.

I wonder if piston engines with sleeve valves would have much the same
benefits. Sleeve valves were a bit of a manufacturing and tolerance
issues, as I understand it, but the Brits seemed quite taken with them
during WWII and before. I think they also had lubrication issues. Just
wondering.

They would and did work well in the Napier Nomad turbo compound.
However there are no sleeve valve engines in current production.
