Over the last couple days, I pulled the Alpine supercharger from the 2001 Kaiser VX I purchased. The truck has been s/c'ed for ~80k miles. I must say I was pretty impressed.
The other 5 chambers look exactly like this: spotless. Pay no mind to the particulate in the corner, it's just a little dirt that I got in there pulling off the s/c'er. I shot some compressed air in there after I took the pic to clean it out. VX and s/c'er are both for sale, BTW
