The Green Monster was the name of several vehicles built by Art Arfons and his half brother Walt Arfons. These ranged from dragsters to a turbojet-powered car which briefly held the land speed record three times during 1964 and 1965.
The land speed record "Green Monster" won the land speed record three times during the close competition of 1964 and 1965. It was powered by an F-104 Starfighter jet engine with four-stage afterburner.
The first "Green Monster", in 1952 was a three-wheeled dragster powered by an Oldsmobile six cylinder engine, and painted with left-over green tractor paint. The name was applied on the car's first outing by the track announcer, Ed Piasczik (Paskey), who laughingly said "Okay folks here it comes; The Green Monster", and it stuck to all Arfons' creations. The car only reached 85 miles per hour (137 km/h), 20 miles per hour (30 km/h) short of the fastest car, but by 1953 the Green Monster Number 2, a 20-foot (6 m) long six wheeled car powered by an Allison V12 aircraft engine, was hitting 100 miles per hour (160 km/h) in the quarter mile.
Green Monster Number 2 was painted by Arfons' mother to resemble the World War II Curtiss P-40 Flying Tigers fighter airplane, with an open mouth showing large teeth. The top speed of the car was estimated at 270 miles per hour (435 km/h), and it could reach 140 miles per hour (225 km/h) in nine to ten seconds from a standing start. Running on passenger car tires, the car required four wheels on the rear drive axle to withstand the power. At the first World Series of Drag Racing at Lawrenceville, Illinois, it clocked the highest top speed at 132.35 miles per hour (213.00 km/h), and eventually a world record of 145.16 mph (233.61 km/h).
