Can I join two compressors together in order to increase size/cfm?

[BlueOvalStangGT]

After some research, I have found that I need a minimum of 60gal, and 10+ cfm at XX psi. My compressor is only 25 gallons, and ~8.2 cfm. I know I can join a compressor and a tank to increase capacity(what affect will that have on pressure?), but can I connect two compressors? in order to increase cfm/capacity?

Sure, you can do this. Duplex compressor systems are the norm in heavy commercial and industrial usage. They will be usually set up so the the turn-on pressure of the second compressor is less than the turn-on pressure of the first one, so that if the load is minimal, that only one compressor will run.
I have a couple of buddies that do this exact same thing in their shops. It will however, require that both compressors have relatively the same pressure capability. It does not work well if you tie a 1 stage and 2 stage compressor together. The CFM will be the direct sum of the two compressors at a given pressure, and it will have no effect on pressure at all given that both compressors can make the same pressure.
