    The picture of the bare cast block are wartsila 12V W46's the piston and con rod are for a wartsila 64 (most powerful 4 stroke engine ever made) the last picture is a crank shaft with big ends installed for a 18V w46

    Incase you wondered I work for wartsila this is one of our factories in Italy

    We make the most powerful engines on the planet (14 cyl Sulzer flex 96)

    How do you balance a crankshaft that size?

    By application of engine balancing theory, rather than by putting it in a giant spin balancer, I would imagine. Besides, an engine that size is a slow turner, so being a little off shouldn't be a huge deal.

    On the contrary. These crank shafts are static balanced. A lot of the calculation is done before but when a new design is made there are a lot of balancing corrections.

    The W46 spins @ 514 or 520 RPM depending on the application and these engine produce 1.25 Mega watt per cylinder and this is for a 18V so 22.5 Megawatts of output or 31,500 HP @ 514 RPM May not seam like much but in terms af relativity the piston speed is the same as most engines. 13,000 RPM seams like alot on a bike but when the piston only moves 50mm it really ist traveling that far Vs a large engine like this where the piston is traveling 600MM or like on a slow speed 2 stroke 2.5m

    This actually a competitors engine a bit smaller then ours but you get the idea

    Someone is already thinking about how to build a motorcycle around that.
