[Vwdiesel] Grenaded turbo!!!! OH! OH!

[James Hansen]

sometimes blades just fail.  Very very very rare, but on occasion, they 
do.  Sucks but <shrug> sometimes things break.
I have  a few used compressor turbines I was given to play with... they 
are surprisingly tough- VERY good alloy.
I wonder if surge would be enough to shatter the vanes?
