Supersucker ideas

So I have a 60g compressor tank laying around that I need to use for something. I was thinking hook it up to the vacuum on the ol IDI to draw it down. Anyone know how much vacuum the pump will pull? Or is it time for some testing?

how much time do you have to draw it down and to what level?

ideally draw it down all the way. I am also looking at refrigeration vacuum pumps. Pressure in Denver is only like 12 PSI, so I am limited there.
