The
second turbo sent turbine fragments back into the exhaust port and took out an
apex seal.
This cost me a housing, a set of seals and a drive to North
Carolina.
Hi
John,
How
confident are you in this diagnosis? Did you actually find pieces of
turbine blade imbedded in the housing? Did Bruce says he's seen this
plenty of times before?
I've got to
admit that I have a hard time believing this could happen. As Ed
said, they're spinning fast, but the energy will be
mostly centrifugal force, with some forward momentum thrown in. When
you think of the angle that the exhaust hits the turbine, it just
seems really unlikely this could happen.
I've always
wondered if that failure didn't happen just the opposite.
If detonation broke an apex seal, it would go into the turbine. This
in fact happens all the time on the
cars.
Good luck
with your new turbo.
Rusty (new
kits are soooooo
nice)
