I had it installed at Z1 last weekend. I did not dyno my car after the install because the guys at Z1 said it would not really increase hp. However, they said that it would allow my car to rev much faster and should feel the difference on the top end.

I have some other mods (CB, Intake) so it's getting harder to notice the differences in things. I would say that the AMS Pulley is much larger than stock though.
