I don't have my new car yet, but I have calipers I can go measure it with when I do. The stock crank pulley is supposed to be 133mm diameter or so, eyeballing it the stock water pump pulley is something like 105mm
The MWR pulley is still slightly smaller than the stock pulley, so 5"=127mm is probably a greater diameter than the MWR pulley.
I believe the stock pulley is steel since every picture of an old engine has rusty pulleys, so it should be more than strong enough to hold a plastic or aluminum sleeve.
The MWR pulley is aluminum, but thicker than the stock pulley (as it should be). The guy who runs MWR got back to me and said they only went 6% because clearance is tight, so I guess that means I should attempt to make this a cost saving exercise hehehe. @Daox are you interested in some carbon fiber infused filament?

Superchargers typically need quite a bit of torque to drive, are you sure a plastic pulley is a good idea for that? I would go metal for peace of mind.
