1991 Mustang Gt ProCharger D-1B Setup?

Hey guys, so I just bought my second mustang last week. A 1991 Mustang Gt w/58k miles, 306 H/C/I and some sort of internals he said the compression is 9:1, 24lb injectors and upgraded pump. It came with a ATI procharger D-1B w/12rib pulley not installed yet...So my question is what do I need to get this thing installed? Can I keep my A/C? What type of power could it make? How much boost does it put it out? Please school me on this thing. Also any pics of this installed on other foxes would be great.
