    Really big babbit bearings. Babbit bearings that require a crane to lower them into place. And, if you look closely, you'll notice that there is a series of permanent ladders built into the crankcase so mechanics can climb around to inspect things inside the engine.

    The scale of the thing is just astonishing. Over 100,000 HP @ 110 RPM! Most engines won't even idle that slowly.
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.

    Damn, how big is fuel tanks? And who mixes the oil with the fuel?

    It would be interesting to hear it run on a test stand. The thing is huge, but it only turns @ 110 RPM.

    You can get another 30K bhp by adding alcohol. It thins the mix to increase fuel flow but I have heard of using propane injectors. Only problem with adding alcohol though is that it breaks down the lubricating qualities of a 2 stroke system.
