I was running a sanden engine driven compressor, but the new engine fits so tight, there is no room to run a compressor off the engine.
The Puma is the replacement for that.
I found that I really didn't need the power that the engine driven compressor gave me - I only used it a couple of times for running power tools (and burned it up once..) and I also hardly ever fill tires with it. I mostly used it to drive the front ARB, so the Puma has enough capacity/power to do what I need. I will give up some tire on filling tires, but like I said I hardly do that so..
