Turbo #4: Stock T03 Used. Not rebuilt.
Installed while waiting for parts for T04 upgrade. On loan from Bob Tiley for "destructive testing". Mission accomplished. :) I babied the thing. Boost kept below 34 @ 5000'. Lost turbine blade during runup (this afternoon). Misbalanced turbine caused oil release into exhaust and intake. Lots of smoke. Runup aborted.

Turbo #5: Turbonetics T04-P50 - new
Sitting on the bench awaiting install. All parts now in hand. Hope to have it installed next week.

The failure modes are fairly benign. The airplane can fly straight & level with a dead turbo.

I know this is the experimental category, but enough is enough!
