air compressor size????

This thread might help http://www.forabodiesonly.com/mopar/showthread.php?t=173756 My 5 hp Champion puts out 19.1 CFM at 125 psi, 16.4 CFM at 175 psi. I have an 80 gallon tank. It takes less than 5 min to cycle f/0 psi to 125 psi as that is where I have my pressure switch set. Here is a link to a compressor size guide http://www.jennyproductsinc.com/howtochoose.html
