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.

Still could be done with two flapper valves and a fan.

I'm building a cozy MKIV, and I plan to use a heater core, which will
run
coolant through it all of the time, and act as secondary cooling. I
will
then use a flapper to either dump the output air from the heater core
into
the engine compartment, or into the cabin.

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.
