I think the rotor is too narrow. That compromises the rotor bearing
and limits the RPM. There is a proper ratio of width to diameter for
plain oil pressure fed bearings. If this is too narrow the plain
bearing loses load capacity.

I spoke to them about it at AERO in 2009.

I think Dankwart worked for Felix Wankel as a technician.

Mazdas 10A was very successful in markets outside N. America once the
seal issues were solved. That happened early on. Those had 60mm wide
rotors and made 270HP with pports for racing. Then for the RX3 in N.
America and the RX2 they widened the rotors to 70 mm for the 12A
engine which gave even better success. The 13B and Renesis would have
done better with dual plugs side by side for four per rotor. Better
combusrion and BSFC.

Thje 10A and the 12A had much better bearing ratios than the Supertec.
