I think the crank requires 6 bolt mains though.

Rob,
Should be good for at least 400 HP. Where did you find those tiny mechanics?

Must be from the newest SUV. You had to figure someone would be bigger than the Ford Excursion someday!

Bet it gets something like 4gpm (4 gallons-per-mile) <img border="0" title="" alt="[Wink]" src="wink.gif" />

Rob,

You could make at least 10,000 HP in your car with that engine, but I'd bet the max speed on it is only 2000 rpm!

You had better keep that small block.

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 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 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 Yeah,baby!
Maximum torque: 5,608,312 lb/ft at 102rpm yes, that's 5 million lb/ft of torque!

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 it's most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour.
