Green Monster (automobile)

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 that briefly held the land speed record three times during 1964 and 1965.

The land speed record ''Green Monster'' set the absolute record three times during the close competition of 1964 and 1965. It was powered by a General Electric J79 taken from an F-104 Starfighter. The jet engine had a four-stage afterburner.

Early dragsters

The first ''Green Monster'' appeared in 1952. It 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 , short of the fastest car, but by 1953, ''Green Monster 2'', a long six wheeled car powered by an Allison V12 aircraft engine, was hitting in the quarter mile.

''Green Monster 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 , and it could reach in nine to ten seconds from a standing start. Running on passenger car tires 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 , and eventually a world record of .

The later cars had various paint schemes where green was not necessarily the dominant color. The six-wheeled ''Green Monster 6'' became the first dragster to break in the quarter mile. ''Green Monster 11'', Art Arfons' favorite, hit to beat Don Garlits.

Arfons used an Allison V1710 in several ''Green Monster''s.

Land speed racing

The Arfons brothers split up, and each became interested in land speed racing.

The most famous ''Green Monster'' was powered by a surplus F-104 Starfighter General Electric J79 jet engine, producing static thrust with four-stage afterburner, which Arfons purchased from a scrap dealer for $600 and rebuilt himself, over the objections of General Electric and the government, and despite all manuals for the engine being classified top secret.

The engine had been scrapped because of damage caused by ingesting a bolt. Arfons removed 60 blades out of approximately 1000 in the engine, removing broken blades and their counterparts at 180 degrees or the pair at +/-120 degrees to maintain balance. He tested it by tying it to trees in his garden, which drew complaints from his neighbors.

This car, painted in red and blue, set the land speed record three times during the close competition of 1964 and 1965 with averages of in the flying mile (despite blowing a tire on the last record run). It competed against ''Wingfoot Express'' (built by his brother Walt, who could not pilot the car himself, having suffered a stroke) and Craig Breedlove's '' Spirit of America – Sonic 1'', which eventually set the record at .

In 1966, Arfons returned once again to the Bonneville Salt Flats but reached an average speed of only . On run number seven at 8:03 a.m. on November 17, Arfons crashed his vehicle travelling when a wheel bearing seized. He subsequently built another ''Green Monster'' land speed record car but sold it to California rancher Slick Gardner without driving it.

Later vehicles

In view of his wife's concern over the risk involved in land speed record racing, Arfons instead turned his talents to turbine-powered tractor pulling with great success, fielding a series of ''Green Monster'' tractor pullers with his son and daughter.

However, in 1989, Arfons returned to Bonneville with ''Green Monster 27'', an , long two-wheeler. The car left the ground at , and Arfons rebuilt it into a less radical four-wheeled vehicle for 1990 but could manage only . In 1991, he tried again, but once again, he had to give up on handling problems.
