Before I melted through the high pressure output hose, we managed to air up 14 tires in the same time it took axle to air up his four tires. As far as output I can't imagine getting more output from an electrical compressor over a belt driven set up. I have about a $100 for my set up, but I also had a lot of the parts sitting around the house. I would think that you could put together a complete system from scratch for $200 (plus the compressor) if you bought everything new.
