Thanks for the help and advice.
Wren e-mailed me and said you are correct about it being balanced from the factory. I put it in the engine like it was from the factory and got a bad vibration at around 25-30K then the engine stopped. Carlos balanced the turbine wheel originally so I sent the turbine, shaft and compressor back to him to dynamically balance.

Hal,
That seems very odd ! When did the vibes start ? On start or spool down ? There must be something else wrong with the motor . A component would have to be grossly out of balance to cause something like that at such a low RPM . I hope you get it worked out . Please report back with Carlos' findings.
