Interstingly enough, the compressor is still being manufactured for OEM
applications. A company called Climate Control Inc. (CCI) in Decatur, IL
bought the tools years ago and their main customers are in the heavy truck
business (Freightliner, for example). It is big, hard to mount, noisey but
it is pretty efficient and it has an oil sump which the Sandens, Zexels,
Densos, etc. don't. This means, if you can keep the oil in it, it will run
forever (it is not uncommon to get 750,000 miles in an over the road heavy
truck.

The one in my 87 Coupe GT has 113,000k and is running happily and it too has
spent its life in Texas. The rest of the A/C system is a poor afterthought
on the part of Audi. Apparently, they finished development on the car and
said "Damn! now they want to sell our car in the colonies, we have to throw
an air conditioner at it".

And throw it, they did. It is under condensed so it runs very high head
pressures and the blower is so loud you won't hear the pounding of that 2
piston York.

So don't think about increasing performance without figuring out how to
dramatically inproving the condenser.
