Dino/Skip:
I wonder if the limited air is caused by the 1.5" input hose that Lancair
calls for? On my ES I used the 1.5" hose as the input to the first heat
muff, 2" to the second, and 2" into the cabin with an Aircraft Spruce SS
inlet box. I have not flown yet but to use a 2" input hose to the muff and a
1.5" output does not make good engineering sense. (PV=nRT)
It seems to me there are many places for the air to escape (>= to 6 sq in).
That is, unless you were to seal all the penetrations (aileron control rods,
flap control arm, rudder control, etc.) to minimize cold air flow. I don't
intend to seal openings until I fly to see how effective the heater is.

Dino,
I have the same low airflow problem with my ES's heating. One thing that
may be contributing to it is that I have a T fitting in the air hose to my
heat muff that diverts some air to my gascolator shroud. <<<
