I had brief conversation with them last fall and they designed the gearbox with the intention of offering higher horsepower options:
"We do have plans for a higher horsepower engine. When we designed our gearbox we intended to do engines to about 225 hp from the start.
Our intent is to do a 155 hp normally aspirated 2 liter and a 200 hp turbo version"I did not mention a rotary engine specifically though.
