'Rare Bear', Lyle Shelton's highly modified F8F-2 Bearcat returns from a practice run. The wet spot on the pavement beneath the tail is excess from the spray bar, which pumps several gallons of water per minute directly on the oil cooler in an attempt to keep oil temperatures from exceeding 100 deg. Celsius. The big R-3350 radial puts out over 4000hp, and it takes a lot of cooling to keep the engine from consuming itself: the Bear carries 40 *gallons* of engine oil. Race fuel is special-order 160 octane aviation gas at $10 a gallon; Rare Bear burns 10 gallons per minute at race power and and has a fuel capacity of only 180 gallons.
