but the CFM (Cubic Feet per Minute) it can move. It has to be able to make up
for the leakage. A slow pump that can acheive perfect vacuum will be less
effective than say, a powerful Muffin fan with some kind of wastegate flap.
In fact, you'll probably WANT a small gap so that your vaccuum cup isn't
dragging on the foor, and all the downforce is on your wheels.
