My brother and I did this to my '89 Sidekick, using the stock A/C compressor. It works quite well. We used an inline oiler, like what air tools use, to keep the pump happy, then run the compressed air through the condenser to cool it. After that, the air goes through an oil removing filter, then air line splits into a small tank, a pressure switch (on at 90psi and off at 110psi, I think), a pressure releif valve (125psi), and lines to a quick connect and an in cab pressure gauge.
We largely left the A/C plumbing stock, and used all the stock A/C wiring, so the electric fan tuns on when the compressor is running, keeping the compressed air cool. The pressure switch we used even fits into the stock wiring harness.
If I remember correctly, with the engine held at about 3000 rpm, the system will take a 30x9.5 tire from 12psi to 24psi in about 15 seconds.
Unfortunately, we didn't take any pictures of the install or final product.
