Ken,
That's a good thought.  I had only considered using outside air from an
armpit scoop.
I'm just ready to build the housing for the heater core, so I'll build it so
that I can also use the recirculate option, if need be.

Thanks for the tip.

Steve, that is exactly my system. It works very well, but Ken is right.
On very cold days when I go very high and it's even colder, the engine
is running so cool that there isn't much heat. If you live in the
Midwest you would probably need the recirculation option.
