    I need a hull for this motor...

    Any suggestions? It's a 10 cyl. "long block". Output is approx 109,000HP.
    Looking to have it ready for racing this summer

    Believe it, or not, A BOAT.

    Oh, and it comes in a larger 14 cyl. block, too...

    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. The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.
    Some more facts on the 14 cylinder version:
    Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.
    Length: 89 feet
    Height: 44 feet
    Maximum power: 108,920 hp at 102 rpm
    Maximum torque: 5,608,312 lb/ft at 102rpm
    Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption). Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion.
    For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range.Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.
    A cross section of the RTA96C:

    The internals of this engine are a bit different than most automotive engines. The top of the connecting rod is not attached directly to the piston. The top of the connecting rod attaches to a "crosshead" which rides in guide channels. A long piston rod then connects the crosshead to the piston. I assume this is done so the the sideways forces produced by the connecting rod are absorbed by the crosshead and not by the piston. Those sideways forces are what makes the cylinders in an auto engine get oval-shaped over time.

    Probably a VLCC or ULCC.
