The idea that you had is fine. The situation is like pulling carb heat during a decent. (everybody remembers to do that on their carbureted planes right?) Some intake preheat will help a NA engine. A bit of trivia, when the "Norton" wankel was first built, (AT BSA!) they passed the intake air through the rotors prior to putting it into the carbs to improve efficiency. I really like the high pressure system injecting into the combustion chamber. With that system eventually you could lose the throttle body altogether. Better efficiency would result. Ask Rolf about throttling losses sometime.
