Paul,

If the 720 CID class is running about 700HP from the turbo O-520/550
recips
and an eight with possible 1,000HP; Would the 3 rotor be competative?
The RB
engine at 900HP with Al end housings should be lighter. When the
powers that
be governing Reno said rotaries would be limited to three rotors, was
there a
stipulation they had to be Mazda dimensions? Just thinking.

I don't have any details. It is just hearsay at this point.
I think with the right gear box one could get 1000 HP from
a turbo 3 rotor for 15 minutes. The Bell 47 final drive box might do it.
The aircraft it is in must be available to the public as
a 2 person aircraft so that pretty well limits the choice
to a Nemesis Nxt.

Sounds like folks have the racing itch!
Another alternative might be to adapt an existing airframe - a laminar
re-profile of a previous competitor such as a venture would go a long way.
Tracy's redrive may survive (inverse proportionally) with the increase
in HP.  Flexplate/AL rivet/damper upgrades come to mind.
ceramic/beryllium rotors!
