Probably running alcohol. I used to see lots of rigs like that at Glamis running without sheetmetal and because alcohol runs cooler no fan/sheetmetal = more power. But I did not stay at a Holiday Inn last night so I could be wrong. ;-}

The owner said he had a paten on some type of coating that would make it run cool enough with out a fan, I say BS... I was really hoping Henry Schmidt would chime in, as I would like to know if he has heard of this & seen it. BTW, I did see it run...

Well, I guess motorcycles do not use a fan, so for racing it might be alright. I would not want to be driving on a tight canyon road/ hillclimb where there is not as much airflow, though.

This picture appeared in Road & Track in the 50's. I found the mag at a church rummage sale about 20 years ago and scanned it. The engine in on a factory dyno.

I wish you had a high res picture of that, that is the coolest engine pix that I have ever seen.. that would make a super cool poster...

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 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.
