Interesting video posted last month from Powerstrokehelp http://www.youtube.com/watch?v=hioVGEIegTQ&list=UUQz2vFEc1m-WGKf6g-pz9DA&feature=share Not sure if it was posted here or not already but ...
This guy tore apart a turbo from a 6.7 PSD. Starting at this post he tries to smash, cut, destroy a bearing from it. He never could. Not sure how they are turning to dust as stated in the video. Looks more like the races are weak...
