I'm not talking about just one motor but 2. A modded .21 and a tuned .28.
Both were broken in using differant methods. Yet both tuned and ran virtualy the same. The temps at race tune for both engines was in the 225-235 range. I tuned for preformance, not by temp, and both were slightly rich. Running the engines rich enough to get the temps down below 200 degrees is just not practical. I don't know what I am missing. The preformance was fair at best with slightly rich setting I was running them both at. The engines did run flawlessly through out. No suprizes at all.

I'm not going to go into how each engine was broken-in, but it was differant for each engine.
