[GH85Carrera]

For those who haven't seen one before.....a cutaway of the mighty (British) Napier Deltic opposed piston, 2-stroke diesel engine. They were used in locomotives, boats, and FDNY's Super Pumper fire pump. Three crankshafts, 9 or 18 cylinders depending on model, and the 18 cylinder version was good for over 2000hp for short bursts. I think the continuous rated output was about 1800hp, with a 1000 hour life expectancy between overhauls.
