93% noise reduction and 47% heat reduction  This is phenomenal!

Nothing really new as Rolls Royce built something similar.
What they are not saying is the weight of the engine will double
and the displacement is half as it becomes a supercharged one rotor.
The HP will go down. The size per HP may be closer due to the
supercharger. The HP per cubic inch of the one rotor would also  go  up due to the supercharger. It would be easy to make
a p-port version out of a two rotor Mazda 13B.

Yeah, I remember suggesting this with a 3 rotor a few years back....
2 rotors feeding into one.

Well I still think the turbo charger based turbo compound
rotary would be a lot lighter and more powerful. Both will need
an intercooler.

Paul Lamar

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.
