I am in the midst of being able to offer a far greater quality option out there for you guys with a dual crank pulley set up with a spacer inbetween. I'm still working on pricing with my machinist but as many of you know Dan had his spacer that came with his supercharger kit (manufacturer not to be mentioned) grenade on him. After taking mine off I found that mine wouldn't be too far behind his, 2 of the 3 dowel pins had already broken off. Just a word to the wise for those out there with a spacer that uses only the dowel pins I would be very cautious. My spacer will also be a bit of an upgrade to those using the spacer that has the 6 bolt holes going all the way through the spacer as well. Feel free to PM me if your interested in a new spacer complete with all hardware to bolt on and go. I'll update with a price once I get it nailed down with my machine shop.
