Triumph TR4
The Triumph TR4 is a sports car produced by the Triumph Motor Company from 1961 to 1965. As the successor to the TR3A, the car was based on the chassis and drivetrain of the previous TR sports cars, but with a modern body designed by Michelotti. In spite of its modern styling, a total of only 40,253 cars were built during its 5-year production run. In comparison, the TR2 sold 8,635 units in its 3-year run from 1953–1955; 74,800 TR3s in an 8-year run from 1955 to 1962; 94,500 TR6s in an 9-year run from 1968–1976,; and 111,500 TR7s over a 7-year run from 1975–1981.TR for Triumph, Chris Harvey, 1983, Styling and coachwork Code named "Zest" during development, the new TR4 body style did away with the cutaway door design of the previous TRs to allow for wind-down (roll-up) windows in place of less convenient side-curtains. The angular rear allowed a boot (trunk) with considerable capacity for a sports car. Advanced features included the use of adjustable fascia ventila ...

Triumph TR4A
The Triumph TR4A is a sports car built by the Triumph Motor Company at its Coventry factory in the United Kingdom between 1965 and 1967. The TR4A was an evolution of the Giovanni Michelotti styled TR4. The car had been favourably received for its overall performance and many amenities but criticized for its harsh ride. The TR4's Hotchkiss drive system was replaced with an independent rear suspension, indicated by an "IRS" badge attached to the TR4A's rear. Changes from the TR4 The new rear suspension was a semi-trailing arm system with coil springs and lever-arm shocks. This system more closely resembled that of the Triumph 2000 than the swing axle systems used in the Herald or Spitfire. The chassis was redesigned to accommodate the new suspension at the rear, with extensive changes to the side members and cross-bracing. The redesign had the desired effect, with reviewers commenting on the improved ride comfort, although some felt that the car's handling had not improved. The ...

Roadster (automobile)
A roadster (also spider, spyder) is an open two-seat car with emphasis on sporting appearance or character. Initially an American term for a two-seat car with no weather protection, usage has spread internationally and has evolved to include two-seat convertibles. The roadster was also a style of racing car driven in United States Auto Club (USAC) Championship Racing, including the Indianapolis 500, in the 1950s and 1960s. This type of racing car was superseded by rear-mid-engine cars. Etymology The term "roadster" originates in the United States, where it was used in the 19th century to describe a horse suitable for travelling. By the end of the century, the definition had expanded to include bicycles and tricycles. In 1916, the United States Society of Automobile Engineers defined a roadster as: "an open car seating two or three. It may have additional seats on running boards or in rear deck." Since it has a single row of seats, the main seat for the driver and passenger w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porsche 911
The Porsche 911 (pronounced ''Nine Eleven'' or in german: Neunelfer) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged.Corlett, p. 12 The engines were air-cooled until the introduction of the 996 series in 1998. The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models. In a 1999 poll to determine the Car of the Century, the 911 was fifth. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bob Tullius
Robert Charles "Bob" Tullius was born 7 December 1930 in Rochester, New York. He is best known as a race car driver and racing team owner. Early years Tullius considered a career in teaching after graduating from high school. He served a term in the US Air Force, and while there quarterbacked the Chanute Air Force base football team until a leg injury put an end to his playing. Tullius took a job in sales with Kodak, first in Rochester and later at Alexander, Virginia. In 1960 Tullius bought a Triumph TR3 for his wife. She rarely drove the car. Tullius took the TR3 to racing school himself, and won the graduation race. In 1972 Tullius was in Bangkok visiting a friend when he was struck in the street by a chauffeur-driven car and injured. Motorsports career Tullius' racing career began in earnest in 1961, when in his first four races he finished first or second, and won the points championship. For 1962 Tullius asked Triumph to provide him with a TR4 to race, promising to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kas Kastner
Robert W. Kastner (30 August 1928 – 11 April 2021), commonly known as R.W. Kastner or Kas Kastner, was a builder and tuner of racing cars, a racing driver, and an author. He also raced sailing boats competitively. At different times he was Director of Motorsports in the United States for both the Triumph Motor Company and Nissan. Kastner has been called one of the most influential Americans in the history of Triumph cars. He coined the maxim "Never be beaten by equipment." Early years Kastner was born in Batavia, New York. He graduated High School in 1945, then enlisted in the US Army for a two-year stint, during which he was stationed at Fort Carlson in Colorado. After his discharge he returned to Batavia briefly, where he taught himself to drive in a 1934 Plymouth. He soon returned to Colorado where he earned a living in a variety of jobs, including managing the pool-hall portion of a large bar, where he earned some extra money hustling pool. His next stop was working as a mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bias-ply Tire
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

Overdrive (mechanics)
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is ''over-geared'', and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM. The power produced by an engine increases with the engine's RPM to a maximum, then falls away. The point of maximum power is somewhat lower than the absolute maximum RPM to which the engine is limited, the " redline" RPM. A car's speed is limited by the power required to drive it against air resistance, which increases with speed. At the maximum possible speed, the engine is running at its point of maximum power, or ''power peak'', and the car is traveling at the speed where air resistance equals that max ...

Rack And Pinion
A rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear ...

Standard Wet Liner Inline-four Engine
The Standard wet liner inline-four engine was a 2,088 cc inline-four, inline four cylinder petrol engine produced by the Standard Motor Company. Originally developed concurrently for passenger car use and for the Ferguson TE20 tractor, it was widely used for Standard passenger cars of the 1950s, most notably the Standard Vanguard, Vanguard. Later it was successfully used in Standard's popular early generation Triumph TR, Triumph TR series sports cars. The water-cooled overhead valve engine featured novel advances for an immediate World War II, post-war design, which included thin-wall bearings with replaceable Plain bearing, shells and loose-fitted wet liners. Origins The engine's origins lay in the wartime production of Bristol Aeroplane Company, Bristol aero engines at the new Banner Lane shadow factory, operated by Standard in Coventry. From 1939 this factory produced Bristol Hercules engines, an air-cooled radial engine, with Bristol's typical sleeve valves. With pe ...
