Just put my .21 trinity in my truggy. Located down in S. Fla, and its basically 80 - 90 degrees with about 80% humidity (closer to 95% after it rains, which lately has been every day at 3:00 PM).

Ran the engine with a ExTech Turbo Medium (TRI40112) Plug and when the car idled it just shut off.

So then I switched to Turbo Hot (TrI40110) Plug and that seems to have resolved the issue....verdict is still out until I can get a damn tank through before it starts to rain again. But at first glance, the car was just plain faaaaaast without any issues...had to lean both top and bottom, again, I suspect due to our world famous humidity down here.

If its clear and dry tomorrow, I am going out to our short track....anyone have any suggestions......Prior posts attribute plug failure/shut down to oil in the engine...ideas/suggestions welcomed...thx.
