What is optimal operating temp for JP engines ? 100C ?
I'm running 120C ( 90% humidity, 34C weather, 42C track temp, maybe less than 50 meter above sea level ).
With those ambient conditions it's Ok to have it at 120ºC.
Actually every engine has it's ideal temp. If your engine is delivering good power and doesn't loose that power over the run of several tanks, and the engine is puffing a good trail of smoke coming out of turns, and the plug's wire is not distorted, and is nice and shiny, then whatever the temp is, thats it.
Most top end engines today like to ruan at 120ºC for optimum power.
