Lotus 34
The Lotus 34 is an open-wheel race car built by Team Lotus for the 1964 Indianapolis 500. Driven by Jim Clark, who qualified on pole, and Dan Gurney, tyre failure led to Clark retiring and Gurney being withdrawn. Development history The Lotus 34 was a very similar car to the 29. It differed principally in featuring a four-cam 4195 cc (255ci) DOHC Ford V8 with Hilborn fuel injection, producing , through a ZF 2DS20 gearbox. Race history At Indianapolis, Jim Clark qualified on pole, with Dan Gurney qualifying sixth. The Dunlop tyres failed during the race, leading to Clark crashing and Dan Gurney being withdrawn, much to Ford's displeasure. Later that year Parnelli Jones won twice in a Lotus 43 at Milwaukee and Trenton. In 1965 A.J. Foyt won three USAC races in a Lotus 34 on his way to second in that years championship, while Parnelli Jones finished second at Indianapolis behind Jim Clark's Lotus 38 The Lotus 38 was the first rear-engined car to win the Indianapolis 500, ...

Dunlop Rubber
Dunlop Ltd. (formerly Dunlop Rubber) was a British multinational company involved in the manufacture of various natural rubber goods. Its business was founded in 1889 by Harvey du Cros and he involved John Boyd Dunlop who had re-invented and developed the first pneumatic tyre. It was one of the first multinationals, and under du Cros and, after him, under Eric Geddes, grew to be one of the largest British industrial companies. J B Dunlop had dropped any ties to it well before his name was used for any part of the business. The business and manufactory was founded in Upper Stephens Street in Dublin. A plaque marks the site, which is now part of the head office of the Irish multinational departments store brand, Dunnes Stores. Dunlop Rubber failed to adapt to evolving market conditions in the 1970s, despite having recognised by the mid-1960s the potential drop in demand as the more durable Radial tire, radial tyres swept through the market. After taking on excessive debt Dunlop w ...

Pole Position
In a motorsports race, the pole position is usually the best and "statistically the most advantageous" starting position on the track. The pole position is usually earned by the driver with the best qualifying times in the trials before the race. The number-one qualifying driver is also referred to as the pole-sitter. The pole position, pole sitter, starts the race "at the front of the starting grid. This provides the driver in the pole position the privilege of starting ahead of all the other drivers" Grid position is typically determined by a qualifying session before the race, where race participants compete to ascend to the number 1 grid slot, the driver, pilot, or rider having recorded fastest qualification time awarded the advantage of the number 1 grid slot (i.e., the pole-position) ahead of all other vehicles for the start of the race. Historically, the fastest qualifier was not necessarily the designated ''pole-sitter''. Different sanctioning bodies in motor sport emp ...

Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ...

Fuel Injection
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake ai ...

Stuart Hilborn
Stuart Hilborn (9 October 1917 – 16 December 2013), was born in Calgary, Canada. Hilborn was an automotive engineer. He became interested in amateur racing on dry lake beds before World War II. After the war, he began experimenting with ideas for mechanical fuel injection, and tested them on his own race cars. Only a few years later, his injectors were adopted by professional racers with notable success, including the first to break the 150-mile-per-hour mark. Starting in 1949, Hilborn-equipped cars claimed dozens of victories at the Indianapolis circuit. Hilborn eventually started a company to sell his injection systems to the public, which became popular with the hot rodders of the 1950s and 1960s. A classic mechanical Hilborn injection system is recognizable by its distinctive flared velocity stack A velocity stack, '' 'trumpet, or air horn, is a trumpet-shaped device of differing lengths which is fitted to the air entry of an engine's intake system, carburetor or fuel inject ...

Race Car
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construc ...

Open-wheel Car
An open-wheel single-seater (often known as formula car) is a car with the wheels outside the car's main body, and usually having only one seat. Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open-wheel cars are built both for road racing and oval track racing. Street-legal open-wheel cars, such as the Ariel Atom, are scarce as they are often impractical for everyday use. History American racecar driver and constructor Ray Harroun was an early pioneer of the concept of a lightweight single-seater, open-wheel "monoposto" racecar. After working as a mechanic in the automotive industry, Harroun began competitive professional racing in 1906, winning the AAA National Championship in 1910. He was then hired by the Marmon Motor Car Company as chief engineer, charged with building a racecar intended to race at the first Indianapolis 500, which he went on to win. He developed a revolutionary ...
