See the heat muff at the bottom of http://www.n56ml.com/corvair/airbox/ . What's detailed is for carb heat, but I put another one on the other side of the engine and piped it back to a cable controlled butterfly valve on the firewall that enters the cabin right between my feet. I love it. It's quick and simple, and will fry you if you open it all the way and the temperature is warmer than about 20F. I have gobs of flow, and it's probably due to me leaving the area around the elevators open so there's always a suction on the cabin. This makes the NACA ducts work great in the summer and the heater an awesome performer in the winter...
