Did it give any signs of letting go or did it just go boom
A few days before I noticed a slight, faint whine at higher boost levels. It never got worse and actually went away a bit. And then it just went bang on a second gear pull. Did you notice that the nut is still on the shaft?
Mine used to whine like a roots charger, then one day, it did the EXACT same thing...
no joke, SAME THING.. thought someone posted up my old pics for a second..
i actually abused mine for a LONG TIME before it finally went boom..
mine went boom 120 miles from home tho!!
my compressor wheel stayed slightly more intact tho, even after driving it 100+ miles without an intake hooked up to it
bearings and all 3 housings were wasted after that, and i darn near ran my engine out of oil as well..
