One thing I forgot to mention in my post above - if you get your supercharger rebuilt, definitely request the Eaton internal parts (bearings, gears, seals). The whole Lysholm, Autorotor, Whipple, Eaton twin-screw thing is confusing - they're basically the same units but individually licensed for their own application, and in the case of Eaton, it's an OEM application that had to pass very stringent long-term durability tests. Eaton spent a LOT of money designing internals that wouldn't kill the auto manufacturer with warranty claims, so their parts tend to be a bit better.
Edit: Talked a guy I know at Kenne Bell and he said my info above was wrong - in their opinion, Eaton is a whole different application and of lower quality than the Autorotor and Lysholm units. For what it's worth, they have a service where they'll rebuild any twin-screw supercharger for $699 ($949 if you ran it dry on oil). They say that their parts are superior to anyone else's - but who knows... At least it is another option for those who live near Rancho Cucamonga. Just my $0.02 - I have no relationship with KB other than having used their products in the past with good results.
