Huge numbers for water cooled and only a 9lb pulley.

Sweet....I have the 9lb pulley already.....where can u order the 2.95" supercharger pulley? Isnit worth upgrading the Supercharger pulley without or before the impeller upgrade or would u recommend doing it together? Also is there any boost increase by going with the 2.95" supercharger pulley alone?
