Supercharger pulley!!

[Dirty_D]

I was wondering if any one new the dimensions for the 10 or 11 lb pulley for my ford racing supercharger(roots style) or had any plans. I talked to ASP today and i need a size. They told me they custom make them. So figured if i could get the sizes and stuff( material type) i could have one made at the local machine shop.
thanks

I think my 9-10psi ASP Pulley is 3.3 inch
