Tarf
The Tarf was a double-hulled record-breaking vehicle designed by the Italian engineer and racing driver Piero Taruffi and used in two versions from 1951 to 1954 for a total of 18 world record drives.
Tarf I
Pierro Taruffi applied for a US patent in October 1949 for a multi-hull record vehicle that differed from the later aerodynamic Tarf concept through a three-hull variant ("trisiluro"), which was never built. When zweirumpfigen Tarf I ( "bisiluro") the installation of a 500 cc racing engine was originally Bicilindrica of Moto Guzzi provided. The V-twin cylinder with a 120 degree cylinder angle developed 47 hp in the post-war period . As Taruffi 1953 in the operation of Race Director to Gilera returned, the more powerful racing engine was Gilera 500 four-cylinder with 65 horsepower at 10,400 min -1 in the right side of the hull of the Tarf I installed, the driver sitting in the left side of the fuselage. With the Tarf-Gilera , Taruffi achieved an hourly world record of 201 km in the class up to 500 cc on October 14, 1954 on the Montlhéry race track . The Tarf-Gilera can be seen today in the Museo dell'Automobile in Turin .
Tarf II
The Tarf II (also Italcorsa ) developed Taruffi for record drives in the sports car class up to 2000 cm³ displacement. Taruffi built a four-cylinder Maserati engine with a displacement of 1720 cm³ in the left half of the fuselage of the torpedo-shaped vehicle, while the driver sat in the right half. With two compressors, the engine is said to have achieved an output of 280 hp . The four-speed gearbox transmitted the power to the left rear wheel via a chain. It was steered by means of two control sticks; the two tail fins were adjustable by the driver to compensate for the cross wind. On March 20, 1951, Taruffi set a record over the flying kilometer at 298.507 km / h. On January 15, 1952, he set further records with the Tarf II , such as the 50-mile record (231.744 km / h), and on April 3, 1952, the respective 50-100-200 km record and the record for 1 Hour (217.414 km / h). The record car Tarf II , which received the engine of the Ferrari Dino 246 after a restoration , was auctioned on May 12, 2012 for 89,600 euros .
