There's a spot when the rotating pinwheel slows and some resistence is noted (your finger tip can feel the spot). The other one spins freely and effortlessly. When you pluck the right wheel to spin, is slows down much faster than the opposite side. This points to some sort of internal resistence, possible a bearing problem. At 130,000 RPMs, TITs >1500, and being a critical component, I've decided to pull the turbo unit and send it to the manufacturer. Maybe this is overkill, but no one can fault me for being cautious. Am I over reacting? Jeff L LIVP (TSIO550E) -- New email address: liegner@embarqmail.com
