Neil,
We have found that to idle well the rotary needs individual throttles. Rote= c makes a throttle body that doubles as a vacuum sensor for their fuel inje= ction. We use a similar FI now. We use our own butterflys. We will need a i= ndividual slide per rotor. Rotec's looks good though.

Neil,
I like his ports, not the same as ours but a good setup also. Ours are configured with the butterfly close to the inside. It really seems to help the idle. Our PSRU has an adjustable mesh and everything will idle down to 1100 engine RPM no problem. (while swinging a prop on the dyno.)
