Vortech Superchager Pulley Sizing
Here is a chart I made to help determine the max impeller speed and approximate boost for each pulley size. Hope this helps you guys out.

Very nice! I expect your chart for Comptech to be up shortly! 
One question/note: I thought the crank pulley was smaller, 5"?

I can do the comptech chart, as long as I can get the following information:
Paxton NOVI 1000 specs:
Supercharger gearing ratio
Supercharger pulley diameter
Crank Pulley Diameter
MAX impeller speed
max efficiency impeller speed (optional)
Typical Boost level for each comptech supercharger pulley size

The comptech crank pulley is closer to 5" while the vortech oversized theirs to 6".
I knew that.

Now if only there was a chart like this for the comptech. I'd like to go ahead and add it to the description of the pulley's

From what I got from sideways going with the 3.8" on a AP1 and making 14psi really gives no benefit and just loses power due to the increase in heat and going past its efficiency.
