help in compresser size

Like strokerscamp said, chk the cfm's at a minimum of 90 psi. Body work tools have the highest consumption of air. I have 2 sandblasters and my compressor 5 hp 2 cyl 60 gallon cant keep up. Also like smallblock said, get another tank that you can hook and piggy back. 2 stage is the way to go, but they are pricy....that will be what I get next.
