Greetings all,

I have a Craftsman 15 Gallon, 150 psi electric compressor rated at 8.6 CFM. The output specs: 4.9 scfm @ 40 psi and 3.5 scfm @ 90 psi. I believe this may not be sufficient to use to perform a differential compression check on my '85 Warrior O-320 D3G. Does anyone know how far off I am? I've heard that a typical compressor to use would have to be rated at 15cfm and a minimum line pressure 125 psi. Is this a correct statement?

Thx,

Joe
