Yea, I'm starting to remember something about this now, as I was quite surprised at the time that the fragment from the exhaust turbine had gone back up into the engine. An intercooler won't help you there and a screen isn't possible either. But really what are the odds that this would happen (I mean for anyone other than John" Turbo Killer" Slade)? Was this just an anomaly or is this a common failure. Some of you follow some of the rotary auto racing lists, have you heard of this type of failure before?

As for strainers, I don't believe John's blown turbo had any damage on the compressor side. IIRC, he believes the turbine side somehow through a piece back into the engine.
