I needed some custom pulleys made for a supercharger setup and based on Tobi's advice I picked Pulley Boys ( http://www.pulleyboys.com ). They own several CNC lathes and CNC mills and are very helpful. I just thought I'd share in case any of you all need to get any custom aluminum work done. Here's the first pulley that arrived today (sorry for the crappy pics, can't find my regular camera so I'm using the camera in my cell phone):

This is the new custom pulley next to a Motorvations pulley that I used to get the offsets right. It's bare now, but tomorrow I'll be dropping it off at a local place for hard anodizing.:

It cost $300 shipped, which included the CAD work and interrupting their production runs to program the machines for this one piece, not bad considering production pulleys from others cost $170. Turnaround time was one day, and the guys at Pulley Boys are very good to deal with. I've measured it and it looks like they got it exactly right dimensionally.

I would assume this guy can do custom Jackson Pullies? You don't have any laying around do you? Nice work!

They do custom blower pulleys, but this is the first alternator pulley they have made.

sweet looking! Hopefully it keeps the belt on now!

I think the belts will stay on after I get it back together. I've been running a pulley I got off of Larry Widmer (Endyn) for the past month that is designed like mine with the raised edges, but the offsets are way off (the belts are visibly strecthed sideways) and the belts haven't wandered yet, so a pulley with raised edges and the correct offsets should keep them on there even under track conditions. It's getting anodized now, but I'll have it back next week and hopefully my motor will be fixed next week too.

I was going to ask how the hydrolock fix is going. Good luck man!
