Depending on the circles you run in, engine nomenclature runs to 2.5, 3.3, 4.0 or that other circle, 7.2, 6.8 and such.
Imagine the 25480.0 if you will.
The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel comes slimmed down as an inline-6 or maxxes out with fourteen cylinders.
With a cylinder bore of 38" and the production of 7800 horsepower per cylinder, this is one mean machine.
I wonder if a 25480.0 would fit on the back of my ride....
