A cold morning start is really loud.

The nitromethane is interesting. I'll have to ponder the chemical reactions.

It's not meant to be serviceable. I couldn't figure out how to pull the impellers off non destructively but I did see a YouTube video on the procedure and if I didn't have a spare I would have taken the time.
