Supercharger Pulley

[Lextreme II]

Recently I have been talking to Rob Welsh from www.boostedtundras.com and he agreed to send me a set of his custom pulley so I can study them. Needless to say, his design and craftsmanship is to dog. This pulley works as an add on to the stock pulley. I think its 6.9" in diameter. He also included a thermo fan adaptor/spacer and very good qaulity also. Here are some pictures. If you are interested in this product, please contact Rob and tell him Lextreme refer you.

damn there must be alot of cnc lathe time on one of those. are they alloy or steel? not the way id go about adding a pulley, but very nice none the less.
and i amagine the above 'to dog' is a typo for 'top dog'
