Here we go. I was close.
NSU Wankel Spider 1964-1967
NSU road tested the Wankel in 1960 for the first time. Later that year they showed a preliminary version of the Spider, a descendant of the Sport Prinz at a Munich meeting of German engineers. Wankel spoke to the conference and won over the many skeptics in the audience.
Displacement 1 x 497 cc
Horsepower 50 bhp @ 5000 rpm, 54 bhp @ 6000 rpm
Torque 52 lb-ft @ 2500 rpm, 54 @ 3000, 57 @ 3500 rpm
Top Speed 95 mph
The Spider competed with the Austin Healey Sprite, which had 5 more horses, but the same top speed. It was about 4 % more expensive than the Austin and 16 % more expensive than the Fiat 850 Spider. About 2375 were produced, although figures of 3000 and 5000 have been reported.
The 1964 NSU Wankel Spider has been chosen as one of the Milestone cars by the Milestone Car Society, 12387 Ridge Dr., Camarillo, CA 93012 USA. Phone: (805) 491-2387.

single rotor engines, the ones in bikes and such, had a tendency to blow themselves apart due to a bad imbalance, thats why 2 rotors are smoother, better balanced.
but i think pettit has a single rotor with 2-300hp or something, one of the big companies has a powerful single rotor.

IIRC when i was doing my research on FSAE engines (i ran into the same idea and then shortly after re-read the rules as you did) back in the 70s there were a few single rotor powered FSAE cars, but they tended to kick too much *** due to their good power to weight ratio and were outlawed.
I still think it would be a cool idea...

If you could build it right wow.. using the front and rear plate you'd have both big secondary ports that you could bridge port and you'd have a very short e-shaft with no flex and bearings on both sides of the rotor.. can we say 15k + rpms.. and then do a p-port on it too.. whoo hoo.. Idle'd be aound 2k to keep it running, but who'd care with that kind of redline...
