I'm planning to have a run of 2.3" pulley wheels turned by one of our machinists. As most of you already know, these smaller diameter supercharger pulley wheels will allow you to obtain greater boost pressures. Many in this forum have seen success running the 2.3" wheels, though for those of us who want a slight increase, I'm thinking of producing a 2.5" as well.

I'm planning to produce this run from 4140 steel. However, we do have a nice round of 316 SS that looks destined for our government project. If you're interested in a wheel, please reply to this post. I'm confident that we can produce them for a reasonable price (Much more reasonable than those other boys, who will go unmentioned).
