My Btt hasn't dropped its nuts yet (still hard to turn over when up to temp with gloves on and the plug in) and I am running around 230 to 240. Monty I think my Btt's nuts are so far north that they are at the RB factory.

Its got a gallon of break in and just over a half gallon of racing on it, including 2 15 minutes mains back to back with a 10 minute down time between with the heater on to keep it up to temp. Its got to be close as I have had to tweek the needles a little at a time the last few runs, but not 100% dropped yet. I can't imagine what she will do when fully broken in running around 250*. I think she'll be close to a 13 minute pit too.
