I did a test last night with one of those temp guage in a radiator cap deals and an infrared thermometer. I idled it for about 30 minutes while testing and tuning other systems, never got above about 180, measured at the cap or on one of the soft plugs. Chrome head nut covers showed about 10 degrees hotter, don't know if that's because they were hotter or because they were shiny and that messes with a laser temp gauge. Those things are magic to me anyways.

The tailpipe temp still felt pretty hot, the pipe ended up being about 120 degrees at the very end of the pipe after the tuning session.


So i would thing getting one of these things to idle in a 70 degree garage (yes, door up) at under 240 shouldn't be an issue.
