Yeah, Vortech pullies make more boost with larger sizes. ie. To make 10psi on a Comptech SC you need a 3.5 or 3.6" pulley as opposed to over 4" for a Vortech making the same boost. But, I think you're referring to the width and key holes of the pullies? If that's the case, I just don't know the differences.

Lots. They both have different ratios.

The comptech pulley has a narrower keyway but a larger shaft hole diameter.
