Will I do not want to come across as disrespectful, you know a heck of alot more than I do about superchargers. I just don't understand how the finish will flake off especially if its not dulled or tarnished, it would have to penetrate the coating to do what you are implying.
I decided to email Magnasun with this question, if they reply I will post it.

Sounds good, maybe some new information we can learn more from.

Please let us know when you get that information.

Toolmaker, you're not the first person on this Forum to use Brake cleaner on your rotors, and those that went before you had very negative experiences. Brake cleaner is KNOWN by us (who rebuild them) as opposed to Eaton (who builds them) to be very bad news.

In fact, the poster directly above me (boosty) is a victim of this himself. You can trust Eaton if you like, or you can listen to the advice given to you on this Forum that comes from experience.

Even Pontiac themselves will tell you that the collective experience on this Forum exceeds their own knowledge on several subjects.

I'm a show me type of guy, so if your right I will find out quickly.

Finished a few days ago, test drive went well no leaks and lots of boost.
I did not replace the needle bearings, seemed ok. I checked with a local bearing shop and the needle bearings are restricted to supplier. I also looked into the secret grease that they charge a arm and a leg for, can you imagine you buy a 5 gal pail and charge 10 bucks a spoon full what a scam.
I ended up buying what the bearing place suggested, -45 to 450 deg synthetic high temp, high pressure I think it was called Superlub.
ttfn

Oh forgot to thank Will for his help. Your write up for cleaning the throttle body was great!
PS lets see what happens to my rotors, the brake clean I used was made by LPS , its used in GM.

Glad to see you got it all done, I have my fingers crossed and hope it all works out for ya. Hope to see you around sometime in the next year, but I guess that depends on your schedule and where you live. Keep that Bonne alive.

So far so good no drop in the boost.

That'* a pretty significant rotor coating loss. Was that from before or after you cleaned them?

The bearings can be purchased pre-greased from several vendors that we use here. It takes about 30 minutes to replace them if you have a press available, and know how to use a grease gun.
