Not to :deadhorse:, but several pages back in this thread I mentioned that I wanted to take some temperature readings with my Kat's 1500 watt recirculating block heater installed. Well this morning I had the chance. Weather conditions at start of test: overcast, outside temperature 24...

I want to do this, but it will be next weekend before I'm home. Hopefully (or not, depending on your climate preference) it will be cooler than it is now. I was thinking of taking some pictures (or video :-) ) of the motor temps measured by the IR gun at different times (say every 30 minutes or...
