Were it up to me, I would call this kit a "Belt wrap kit", not a pulley saver kit .... (I guess it is up to me : )
As you probably know, even in stock trim, there is a minor amount of Supercharger pulley slip. ... when members started increasing the load on the (belt to pulley contact patch of the) belt by increasing the size of the crank pulley and/or reducing the size of the SC pulley, this became a significant amount of slip (particularly with the reduced belt to pulley contact area inherent with the smaller SC pulley route).
The purpose of this kit is to eliminate belt slip (and thereby increase power) by increasing the contact area between the belt and the superchager pulley (by re-routing the belt so that it has more "wrap" on the SC pulley). Additionally, I also wanted to reduce the rotating weight (and load) where practical ... and the icing on the cake was making it look nicer than the steel (and plastic) pulleys that are found on this motor. Another consideration was to retain the stock length belt (which was achieved for this version of the kit). Relative to the load reduction, the alternator pulley is not only lightened a considerable amount, it is also re-sized to slow the alternator down by approx 15%.
hope that answers most of your questions. If not, don't hesitate to send me a note with any other questions you may have.
cheers,
