Second turbo (TO4 hybrid run at peak EGT everywhere I went) lasted about 120 hrs, and now the third one (another TO4 hybrid but I keep EGT (actually TOT) below 900C - about 1600F) has been good for about 170 hrs. (400 total hours on the plane). I have a fresh one sitting in a box ready to install if/when needed. Dave Leonard On Thu, Jun 25, 2009 at 7:39 AM, Bobby J.
