I accidentally did some "research" on that several months ago.
I don't know how hot it got, but the element did explode quite loudly about 15 seconds after being plugged in without being submerged first. Had to rebuild it right after that.
As far as burning the plastic goes, I had that concern too when I first built mine. I don't think it will hurt anything if it touches the plastic as the water acts as a coolant. I got around the the possibility of that by using a plastic plumbing elbow instead of a straight pipe for the handle. This keeps the element parallel to the bottom instead of the heatstick resting on the element on the bottom of the bucket. The gadgets article in the latest Zymurgy magazine also shows that construction, but I first built mine a couple years ago. That guy must have stolen my idea!
The instructions for my heatstick came from this site.
