Similar in concept (split counter-rotting crankshafts) to the Czyz GP motorcycle prototype project some years ago. Every rider who turned laps on it swore by its balance and power. I would have liked to see him succeed in that venture where he is now involved in e-bikes instead.

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S.

Until then, he has published simulated dyno runs of the Moment Cancelling engine, seeing a peak horsepower of 283 at 9,000 rpm, and a peak torque of 172 at 7,200 rpm.

Dang.

Yes, I understand that.
Even if it is 83 HP off that is still pretty impressive for what appears to be a two cylinder engine.

The 1931 Ariel Square Four had counter-rotating crankshafts as well as overhead cams. ;)
