Just found this on the net but I can't vouch for the source:
- too hot = 120 degrees F. (48 degrees C.) Anything above this is scalding and can damage human tissue
- just too hot to touch = 107 degrees F. (42 degrees C.)
- comfortably hot = 90 to 100 degrees F. (32 to 37 degrees C.)
My coil routinely gets "hot" as in, I can put my fingers on it but have to pull them away after 4-6 seconds. This includes an American coil, a French one, a German one and now my new Pertronix Flamethrower coil (all 3ohm, oil filled). How's that for international?
