Mark,
I removed the turbo after about the third flight due to the turbo manifold starting to blow apart.
It was an after market manifold that I had slightly modified. However, it was not the modification that failed. Apparently, the manifold was just not up to the task as it was literally blowing apart at the seams and in the core steel. If I ever get more solid flight time on the engine, I hope to re-install the turbo with a better turbo exhaust manifold, perhaps with inconel. That is likely quite a ways off. I may have pictures of the damage manifold. If I stumble across them, I will share.
Chris

Chris,
Thanks for the flight report. So, what happened to the turbo?

Well, it took several months and countless frustrations following an engine out a while back; but I flew my N/A 13b powered Velocity SE today. Just one circuit at Pearland Municipal -LVJ (formerly Clover Field).
I have yet to notice any squawks and the engine seemed smooth and responsive. I had to coursen the IVO in-flight adjustable prop a bit as I noted engine speed a bit over 6500 rpm and prop kissing 2800 (not sure the exact corresponding numbers hoe the two cuz when I saw 6500, I throttled back and then noticed the high prop speed on the Dynon SkyView.
I need to down load the Dynon data log and see what I may have missed.
I figured some of y'all may be curios.
All the best,
