Richard Sohn one rotor. Two peice end housings. Half aluminum and
half stock cast iron to save weight. Total weight as you see
it with Hirth PSRU roughly 160 pounds as I recall. Less alternator.

Both peripheral ports and side ports. Lots of potential for
staging the ports to get the best of both worlds. Smooth
running at low speeds and high HP at high speeds.

Super simple ignition trigger system. Stock Mazda ignition pick up
removed from a stock Mazda crank angle sensor.

Richard has five hours on the test stand so far as I recall.

Correct me if I am wrong Richard.
