I got a PM about my engine driven compressor, so I figured I would share.
So check this out, my compressor is out of an older volvo, I want to say an 86 but I will get the specifics from my buddy as he is the one who set me up with it. When I purchased my truck it already had the EDC but I ended up throwing a rod in it and had to replace it.
This is what mine looks like...

... and its dual piston... Wooohooo
I picked it up at the wrecking yard for $50. you will have to do a few things depending on your setup. If your running a v-belt no worries the one I have come standard with a v-belt setup; however, I have a serpentine belt so I had to get it modded by a machinist, also run a longer belt.
Mounting is takes a little fab work making your own brackets, mostly out of flat bar bent to perfection.
This compressor I am running is 9.1 cfm @ 3k rpm. It kicks the shit out of the viair 380 in my car as it is .9 cfm constant when the engine is running.
Here is tons of information on EDCs
http://www.jedi.com/obiwan/jeep/york_id.html Look around... The website will describe a mod the will keep the oil from going into your air system as well as how to get the pully off without effing up the clutch system.
I will post some close ups of my setup tomorrow.
