Turbo Systems United (TSU), an affiliate company, started to sell TPL91-B, the largest turbocharger in the world for marine diesel engines, in October 2004.
The TPL91-B, developed by IHI and ABB in collaboration, is already marketed by ABB in Europe and South Korea. This large scale model is targeted for super container ships of 8000TEU class for which demand has increased in recent years. The airflow volume is 55 cubic meters per second. ABB has already received more than 60 orders for TPL91-B and the first TPL91-B will be mounted on the large container ship built by Hundai Heavy Industries and was shipped from ABB in June 2004. TSU has started to sell the TPL series in Japan and Taiwan and has already received more than 500 orders.

That would go on something like, this:
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
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.
