Yes, I was routinely getting 10,500 -10,600 k on my TT .91s but if I said it was with 10% fuel, I was mistaken. I use only 15% or 20/20 in my engines.

The point is that the TT .91 will smoke most engines in its class other than YS. Yes, its a little heavier but most airplanes I built needed the extra weight in the nose anyway.
