They brought their tools, and even took the 2.9L to a secret location and measured everything! I took pictures of everything that they were taking pictures of. Including them walking out of the trailer with the 2.9L in hand! They have custom gauges made for the rotor packs to make sure they weren't profiled. They measured the length and width of the rotor packs. They paid close attention to the gear that sits on the jack shaft to the main rotor packs and the main rotor pack gear. To disassemble it they did not need to pull it off but they did anyway.

Dave Ley and Pat directed to me which bolts to remove to disassemble. Then they measured the inside of the case, the rotor packs, the gears, and then took it to a secret location to measure the rotor pack profile. In one of the pictures you can actually see marks on the rotors where they used their gauge to measure the profile.

I'd suggest everybody scribe a personal something on the outside the superchargers from now on and document it.
