100,000 hp *you think I'm kidding*
12 cylinders of course and no it's not the newest dodge viper...
displacement owns
redlining it at just a hair over 100RPM LOLOL!
how loud do you think that bad boy is?

The military destroyers that use turbines for speed use regular diesel engines for cruising. The same with the Atlantic-crossing-record boats. I think the typical turbine is closer to 0.60lb/hp.hr BSFC (or higher), with an efficiency of 25-28% for constant speed applications, and lower in mobile applications (compared with over 50% for this diesel).
Another disadvantage of turbines is the speed at which they change speed. Not so much a factor in big ships, but turbines greatly prefer constant speed applications.
As an example of the advantages of even a gas engine over a turbine, look at the Orenda aviation engine http://www.mrrpm.com/
So, is that the Curtiss-Wright (formerly John Deere) rotary (the big one)?

I'm pretty sure Caterpillar makes straight 12 engines, too, for generators. My dad would know for sure. He works for them.
And wouldn't it be great if there actually WERE little tiny mechanics? You could have them fix problems while you were driving!

So, did anyone notice that there are ladders that lead down into the bottom of the engine (look on the walls of the crankcase).

But even their largest in-line is an 8 cylinder... the big beasties are Vs.
