Looks good but .54 BSFC is no great shakes :)

It needs a longer intake pipe.

Also offering a 2 rotor and heavy fuel (kerosene) versions!

Yes I noticed that. There are a few interesting features. The rotor is wider while Mazda
and Supertec are going to narrower rotors.  The face of the rotor is flatter reducing
the depth of the bathtub for a give compression ratio.

I am a bit disappointed that it does not have a pressure fed oiling system.
The roller rotor bearings will prove to be problematic.
Apparently it is also a charge cooled rotor type.

They should do a four rotor 130 HP version for the US experimental and light sport  market.
A turbo compound version would be fantastic but they would have to go with oil cooled
rotors and pressure fed rotor bearings. Top RPM would go up to 10K or more.
