I am running the Harrison rotary AC compressor in mine, 5 gal storage. It works great, and it is the stock model for my 4.3. I am unsure of an exact CFM, but it fills my 36x12.5 tires in under a minute. I have it adjusted to 130 psi with a 40psi differential. I am sure its around 6 CFM cause it runs my die grinder fine.Originally Posted by 4x4mike
I also have a CO2 tank, but I think I will leave that heavy thing at home now. I didn't spend the money on a powertank, I just bought a #10 aluminum tank, and a regulator, much cheaper. Good thing about CO2 is that the CFM is there right up till its empty.
