Using carh heat on the ground, with a carb temp gauge can
improve extreme cold weather performance. And the use of
baffles on oil coolers and cylinders is very important.

Heck,,, get out and go flying. The wings love the thick

motor really LOVES it too.

The engine will produce more power with denser air,
but
atomization of the fuel suffers in the cold and consumption
can go up.
Condensation in the engine is much more pronounced in the
cold, too,
and corrosion starts to set in if the thing isn't run until
the oil's
hot enough to get rid of it. Here in Alberta the engine
simply won't
get hot at -25°C; it'll barely get warm, and we've had some
hassles
with corroded cylinders on the coldest engines.
