THIS pic is YOUR supercharger rotors. The OTHER view. I highlighted the coating loss for you, and did it at exactly the same time someone else did. See page 3.
At least 5 people have now told you you have coating loss. You can believe you don't, or you can believe those here that have all said the same thing. You just saw the inside of yours for the first time.
Give a little credit to the members of this Forum for being a WEE bit more experienced with it.
Believe us or not, I don't really care. It'* not like you're going to replace your rotors, so what'* the point? You disagree with a BUNCH of us. Big deal. You think one thing, we think another, so we'll just go our seperate ways. Cool?
For the record, ANY kind of brake cleaner or carb cleaner is a BAD idea and is PROVEN by members of this forum to be a bad idea. You can damage the coating and it may not be obvious until after you install the SC and start using it.
