As it was explained to me, a supercharger rebuild is all about tolerance stacking. You have to tear down the blower, put in new parts, and measure the final tolerance. Then you tear it down again, try different new parts, and measure the final tolerance. Repeat until it's within spec. At the factory, they have boxes full of new parts to use. A smaller rebuilder, who is only rebuilding one part of the supercharger, may only have a limited selection of used parts, hence the final tolerance will be greater. Stiegemeier rebuilt my rotors, but they arrived with a large scratch in the black coating - probably a used part.

For each rebuild, I drove around on the street just fine for about a week, but it blew up as soon as it saw sustained high RPMs on the track. If you're like me and you enjoy squeezing out all the air between the pedal and the firewall, get a factory rebuilt supercharger (I got mine from Jan). It's about four times the price and totally worth it. Or get a TVS900; then you don't have to deal with crappy rebuilds because the blower will last a lot longer. #OT
