Anybody Ever Swap Vortech Pulleys?

[94GTLaserRC]

Per Wes's advice will probably swap the stocker 3.33 for this one:

SuperchargersOnline.com :: Product: 8-Rib, 3.12" Vortech Supercharger Drive Pulley (approximately 10-12psi on most applications)

With the low comp engine and high-flow heads, I should be able to gain 2-3 lbs without affecting the Vortech and maybe not having to change the belt.

Anyone ever changed theirs? From what to what, and how was the gain and/or feeling?

Any tips or suggestions?

Thanks
