I was just over on the VAN's Airforce forum. Paul Lipps (Elippse props) was talking about using carb air heat @ wide open throttle to reduce power in cruise instead of patial closing of the throttle.

This Rotary group talks of reducing power and increasing efficiency by leaning @ WOT, which rotary engines tolerate better than piston recips.

Question for the group?

Would Charge Air Pre Heating be an additional benefit for the rotary?

 Paul was idenifying carb air heat @ WOT as a way to increase cruise efficiency for aircraft with fixed pitch propellers. I simply extended the idea to this group.
