HF 110lb Blaster questions

I am using the HF#68994, 20 lb blaster on the underside of my 66 Dart. It is working quite good. My compressor puts out 9.5 cfm @125 psi, and even with this blaster being small, the compressor still has to work a little to keep up.
I just sold (yesterday) a big new "Bad Boy Blaster", it would hold 100 lbs of media. I would get about 20 seconds of blasting in, and then I had to wait, 30 mins for the tank to fill up again. needless to say, I need a bigger compressor. That's my next tool.
