Kenne Bell supercharger pulleys

[ETW]

Kenne Bells website lists a package of four different pulleys- 2 7/8, 2 3/4, 2 5/8, and 2 1/2. Can anybody give me the the boost levels and/or power increase for each pulley?
Thanks

Keep in mind that I don't think they recommend going any smaller than 2.75" if you plan on using pump gas.
