This is an awsome engine:
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm

Now you've done it! Every bagger owner is gonna want one :>)

Those big SOB's are amazingly fuel efficient if you look at it in terms of tons hauled per mile ... but I still wouldn't want the fuel bill!

Lets see, a 10% increase in Hp would be ....... damn!

 Think thats in production for the 2010 Boss Hoss........

Imagine what it would do with a ported head, wood cam and a blower. 

How do they calculate how much power there is and so exactly?

Looks like a good sized industrial engine,appears to be 6 cylinder,and turbo charged. Wonder what it uses for fuel. Its probilly a walk in crankcase has well being so big. What factory is the picture from Don? Those big engines usually drive some big equipment,I have worked on a cpl of them that big.  Right now where I am working there is some big straight 6 and 10 cylinder engines driving compressors. Hydrogen gas 4000psi+. One of the straight 10's has a turbo does that old girl rock @ 300rpm. They all have 2 big monster spark plugs per head. They are just finishing up a total rebuild on a 10 cylinder one and installing a new state of the art electronic control system on a 50+ yr old machine. Them big old engines with 21st century controls,19th century design...lol..just like Harley.....Bob

Believe it or not, they use a BAD (Big A$$ed Dyno), likely something along the lines of the Froude Hoffman LS370:

The engine in the picture is the Wartsila-Sulzer 14 cylinder engine installed in a Maersk container ship.

Is this the same motor or just similar?

>>Is this the same motor or just similar?<<
Yes, same engine ... one BMF! I believe the first one to be installed was in the Emma Maersk (container ship).

Here is what that monster sounds like under load.

  Umm, not quite 

Imagine about 22-25 Union Pacific diesel locomotives lined up and just idling and that would be pretty close. Outside of the engine room it's actually pretty amazing how quiet they really are. Fascinating pieces of machinery, at least they are to me.

They usually run on bunker oil and its probably going in a ocean going vessel

Would these engines fall into the category that so many Harley riders like to refer to as "jap crap"

     The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient prime-mover in the world today.  The Aioi Works of Japan's Diesel United, Ltd built the first engines and is where some of these pictures were taken.
     It is available in 6 through 14 cylinder versions, all are inline engines.  These engines were designed primarily for very large container ships.  Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them

If you count the gas injection valveson Don's picture it looks like a 6cyl model the 14 gotta be some big monster....Bob

so I guess torque and HP dont cross at 2650 rpm on that thing huh?

Good catch! Here's a shot of the 12 cyl. version and some more detail on the 14:

What pipe would be better.  True duals or 2 into 1 ?
Aw ! forget it, You would probably have to use 20 inch culverts anyways.
