Cody,
The most commonly achieved temperature was 45F, even after a 15-20  
min drive with the temperature 85F to 95F  during all the tests,  
never under
43F in the cool shop.  The sedan would cool the ducts to 42F easily  
within 5 minutes and the entire car would be comfortable if it had  
not sat in the direct sun.

I came to the conclusion that, since the noise with the new  
compressor installed was the same,  some of the noise comes from a  
different
source, fan bearing perhaps.   The a/c plenum seems to heat up more  
in the black avant also, so it takes longer to cool the ducts down.  I
might not have thought it was any problem if I wasn't used to the  
sedan working so well.  I had the new compressor and thought that it  
would
bring things into spec.  After 3 return trips it becomes apparent  
that the shop isn't going to improve things and I lose interest and  
move on to
things that are totally broken where I think the time is better spent.

I didn't know about any of the noise products, or how they work, so I  
will have to investigate.  I have a trip to a/c country next week  
(FL), and
plan on avant to haul all my trash, otherwise it will be spring  
before the a/c gets much attention.  Maybe it needs a break-in  
period.  :-)
