I used a diverted valve from A/S to divert the pilot's fresh air vent through the Ford Mustang heater core. Works good down to about 25 deg. outside air temp. Probably not enough for real cold climate.

For those flying with recirc. air do you ever have windscreen fogging like you do in a car on humid days in the recirc. position? I know in my Camry I am seldom in the recirc position due to fogging but then again my exhalation air is quite a bit closer to the windscreen than it will be in my RV-9A...

If at all possible I hope to be able to get by without running a fresh air supply to the heater core...
