#1 the gasses come at the velocity of a rifle shot
How
fast do you think a piece of turbine wheel is going?
#2 I would go with fractured
apex, or blown corner seal.
There
were no missing parts of apex or corner seals. All were intact and in
place.
BTW John did not find any
corner seals left when Bruce opened the engine
It was
the little rubber things that were missing, not the corner
seals.
By the
way, just in case there's any confusion, we're talking about turbo failure # 2
here, not the latest one.
