GZE pulleys NEW question

[Okami]

I understand some more now...

I want to buy 2 pulleys in the near future but would like to know all your input as I have not idea if these 2 would work together...
Maybe if I buy both - 1 of the 2 would cypher the other one out making the more boost undone...

1. 157mm crank pulley -

This was made by Endevor Engineering to exactly match the HKS 157mm crank pulley size specs, which is the largest sized crank pulley you can run on a 4agze without having to alter, or remove the timing pointer;

It is easily the simplest and least expensive method to increase hp on a 4agze engine, and will increase the stock sc12 supercharger output by at least 2 psi; that is a 25% increase from the stock 8 psi output, and will produce an approximate 20hp gain, from 145 to 165hp; it can be run with the original 4agze SC pulley belt, and it only requires a simple vacuum hose change, known as the 'ABV Mod', to take advantage of the boost increase; no 'Grunt Box', or other complicated mods, are necessary;

2. 103mm Clutched sc12 4agze supercharger pulley -

Bolt on modification, instructions included.
Pulley, Bearing, Magnet and Electronics are New
Will fit both sc12 superchargers
11psi pulley for 4agze engines with FMIC and std crank pulley.
TMIC more psi
