I'm on the third turbo right now. The exact numbers are a little hazy without my logs, but the first one (pure stock off the car) lasted about 70 hrs. Flew N/A for about 50 hrs. Second turbo (TO4 hybrid run at peak EGT everywhere I went) lasted about 120 hrs, and now the third one (another TO4 hybrid but I keep EGT (actually TOT) below 900C - about 1600F) has been good for about 170 hrs. (400 total hours on the plane). I have a fresh one sitting in a box ready to install if/when needed.

Dave,
I thought your second turbo failed last summer at about 130 hours. Are you on your second or third turbo?

Eh, I still need a muffler. I use one and still got a noise complaint on Sunday. But the turbo is holding up so far.. 170 hrs on the latest turbo and still going strong..

Actually I wish you would get the bugs worked out. I might swap out my super charger for a turbo and intercooler and loose the muffler. My muffler is starting to loose "stuff" and make rattling sounds.

For you EE types, I have a question. I am installing a smoke system and wanted to use a relay to control the pump. I bought this relay from Mouser that I thought would do the trick: http://www.mouser.com/Search/ProductDetail.aspx?qs=sGAEpiMZZMtLEhJ5P%2fNsZ6bnrz6%2f%252b%252bJvA50eSiydqPQ%3d
The problem is that if there is any load (like the pump or even the 0.02A indicator LED I installed, then the relay will not turn off when I turn off the signal voltage. So either I do not understand how to use the relay, or I chose the wrong relay. I have checked my wiring in-so-much as to confirm that the signal voltage does turn on and off with the switch, voltage across the 'LOAD" terminals does disappear when there is no load but not when there is a load (current).
Is it possibly because this relay is designed for an AC load? Other suggestions? -- David Leonard Turbo Rotary RV-6 N4VY http://N4VY.RotaryRoster.net
