Never experienced the steam myself, although I can't say I've ever tried supercharging the car at 5F. Coldest I've ever done it was probably in the 40s, which is plenty cold enough to cause that popping sound when it's pulling 250kW.

Oh yeah, the popping was crazy loud as well.

Thinking back to it, the battery must have been extremely warm at the time too, since that 5F was after two hours through a 2 lane mountain road (crossing the range).
