take it apart...remove the rotors...then spray out the snout with brake clean...wipe the rotors off if you want to...then spray brake clean on a towel and clean out the case...but you might as well port that one while it is apart...
You still gonna ship me that case?![]()
You want to be real careful cleaning the inside of the supercharger. I personally wouldn't touch the rotors with anything. Many cleaners will weaken or remove the coating (epoxy for Gen III) on the rotors which will make them (and the supercharger) become very inefficient. The rotor coatings are fragile enough after 10 years of use. The buildup from the EGR will tighten clearances between the rotors and housing and in theory will improve efficiency similar to what water injection does when sprayed upstream of the rotors. If you clean the inside of the housing there are two bearings that need to be greased. They need proper grease. Some people don't use the correct stuff and claim there is no issue, but even then you need to not just stick any old grease in there. The rotors turn at very high rpm. Bottom line is, it might not be as harmless and simple as you first think.
more people talking stupid things about the rotor coating. great.
