Well I put my JJ 1400 back together this afternoon and back in the plane for a couple of runs and the thrust is about the same as with the burned out CC, so a bit disappointing. Max thrust read today was 10 lbs 4 oz outside temp was about 55 but the humidity was way up compared to last time so not a real exact comparison. Also, remember that these numbers are with it in the plane so they will be a little lower than actual output if on a good test stand.

Anyway, I may still play around with the exhaust diameter (Todd? ET?) and see If I can get a little more out of it. I see that the new engines are still being shipped with the two piece cone so Joe must feel it does a better job.
