I would not say that a blower doesn't work at all. They do and did on 2-stroke Diesels. But I doubt that they work at crank-RPM unless they have a relatively huge diameter.
It would need some calculating (blowers can be calculated) before making the first chips.

The blowers on Detroit Diesels are positive displacement ( Roots type)
Large stationary 2-stroke Diesels(back up generators) start on their Roots blowers and run on turbo-chargers for better fuel economy.

This is an old thread but if anybody out there is listening, are the Lee Berger plans still available somewhere? RCM plans are long dead and the few places still providing them like RC Groups only seem to have airplane plans, no engines. I am fascinated by the 2-stroke radial engines Ralph Barnette and Lee Berger built. I have plans for a 9 cylinder engine using Cox cylinders and pistons but would love to find the Lee Berger plans using the K&B .65 cylinders.
