    Crank pulley, -mine went at 65k- check out the ATI Super damper- ATI seems to be popular. I have had no problems with mine!

    Wow, you guys are good, that was it!

    It all made sense in retrospect....

    All the symptoms pointed to the serpentine drive once you thought about it....

    No power - supercharger not turning
    Overheating - water pump driven by the supercharger
    No A/C
    No alternator output

    He also had a leaking thermostat housing - again! The dealer replaced it a couple of years ago when it was still under warranty with the new and improved version. Looks like it didn't hold.

    Yup. :idea:

    I drove a busted crank pulley home from the track. It was fine as long as I kept the AC off and the boost in the vacuum range, i.e. no load on the 'charger.

    Sometimes the issue is the gasket, not the housing. I just replaced the thermostat and gasket on my car, and it's a tricky bugger. The torque spec is really low, too, like 12 N-m. I lubed up both sides of the gasket with a little bit of Sil-Glyde to make sure it didn't bind when I tightened everything up.

    Hopefully it didn't get hot for too long.
