This is an awesome mod and I'm eager to see what kind of UPS drop I can get.
I play Warptorio2 mod and have a tiled quad nuclear steam engine setup.
Heat Exchanger > Steel Pipe > 4 Steam Engines > Pipe > 4 steam engines > Heat Exchanger
I have a noticeable UPS hit when I enter my Boiler Level.
Probably because of 1000+ steam engines all running at the same time.
