The AC unit I bought from Walmart is a Goldstar. I gave it a hard break in,
running it wide open for 4 days until I made a decision which heat pump to
install. Never missed a beat. I paid $86 I believe.

There are variations in fuel controllers for different year airplanes,
then there are the weight disparities, some people removed a lot more
than others, then there is CG, if you are flying with more forward CG
then the others then you will affext your cruise speed. Also there
are discrepancies between different gauges.
I pulled and cleaned my fuel nozzles last year, they were heavily
carboned up, and it did make a difference in power and fuel
consumption.

Seen the discussion concerning the air conditioning problem. You might
want to also look at some of the air conditioning units being used by
the street rodding community. Specifically, www.vintageair.com
<http://www.vintageair.com/> might have something that can be adapted.
Space is usually a problem with most street rods.

So am I to understand Bob, that you are the mystery man behind this
air conditioning breakthrough??

Some more considerations:
The difference between VintageAir stuff and window units is the window
units are self contained. With the auto stuff, the compressor is
separate and generally run off a v-belt. On a piston aircraft that is
not a problem, but where would you attach a compressor on the L-29? Or
is there enough high pressure air available that you could use it? If
there is a continuous source of high pressure air, consider a Hilsch
vortex tube. No moving parts and no space required. However, you'll
need a LOT of air :). Another advantage is you can get both hot and
cold air from them, allowing the proper temp mixture any time of the
year and any altitude (within limits.)

I looked into vortex tubes, and there is no where near the bleed air
available to cool the cockpit. Obviously a window unit would need to
be disassembled in order to seperate the condenser/compressor section
from the evaporator section. refrigerant lines would need to be cut
and run through the cockpit.
Vintage air systems is what I originally experimented with, but they
rely on engine driven compressors, which is the main challenge in out
jets, not to mention cockpit airflow, and condensate removal. The
sandel 505 compressor coupled to a brushless 24v DC motor via pully
drive is the most practical approach.

On the L-29, there is two mechanical power source on the engine: the
first is for the high pressure pump, the second is not in use. Could
it be used for air coonditioning ?
