McLaren M16
The McLaren M16 was a race car designed and built by McLaren between 1971 and 1976 for American open wheel racing. It is the most successful car of the 1970s at the Indianapolis 500 with three wins in 1972, 1974 and 1976 and the last one to win with the Offenhauser engine. History 1971 The car was unveiled in January 1971 to replace the M15. Initially named simply M16, the 1971 version is known retrospectively as M16A due to the successive updates. The chassis is an aluminium monocoque powered by the omnipresent at the time Offenhauser straight-4 engine, which in its 159 c.i. (2.61l) version and equipped with a Garrett turbocharger limited to 24.6 psi (1.7 bar) delivered over 700 hp. Following a trend set by the previous year Lotus 72, the radiators were moved to the sidepods giving the car a wedge shape. Two cars driven by Denny Hulme and Peter Revson entered the Indianapolis 500 under the McLaren team and one more car run by Penske and driven by Mark Donohue Mark N ...

Turbocharged
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger,[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gordon Johncock
Gordon Johncock (born August 5, 1936) is an American former racing driver. He won the Indianapolis 500 twice, and was the 1976 USAC Marlboro Championship Trail champion. Early career Johncock began racing at Berlin Raceway in Marne, Michigan. Johncock began his USAC and CART/IndyCar career in 1964 when he drove for Weinberger Racing. He ran four races in 1964, and then went full-time in 1965. Johncock's first USAC victory was scored at the Milwaukee Mile in August 1965. In 1966, he went winless in nine starts out of 16 races, so he left Gerhardt Racing at the end of the year, to form his own team, Johncock Racing. His primary sponsor became Gilmore Broadcasting and Johncock was the only other "owner-driver" in IndyCar other than A. J. Foyt. Although Johncock's team won six races in a three-year period (1967-1969), things went downhill when Johncock lost the Gilmore sponsorship at the end of 1970. Between 1970 and 1973, Johncock went winless, his team shuttered operations, and Joh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotus 72
The Lotus 72 is a Formula One car designed by Colin Chapman and Maurice Philippe of Lotus for the 1970 Formula One season. The 72 was a pioneering design featuring inboard brakes, side-mounted radiators in sidepods (as opposed to the nose-mounted radiators, which had been commonplace since before World War II), and aerodynamic wings producing down-force. Development The overall shape of the 72 was innovative, resembling a wedge on wheels which was inspired by the earlier Lotus 56 gas turbine car. The shape made for better air penetration and higher speeds. In a back-to-back test with the Lotus 49, the 72 was 12 mph faster with the same Cosworth engine. Chapman's and Phillippe's efforts produced one of the most remarkable and successful designs in F1 history. Taking the stressed engine layout technique from the Lotus 49 and adding advanced aerodynamics produced a car that was years ahead of its rivals. To begin with, however, problems with the handling of the car had to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1976 Indianapolis 500
The 60th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 30, 1976. Polesitter Johnny Rutherford took the lead on lap 80, and was leading when rain halted the race on lap 103. Two hours later, the race was about to be resumed, but rain fell again. USAC officials called the race at that point, reverted the scoring back to the completion of lap 102, and Johnny Rutherford was declared the winner. Rutherford famously walked to Victory Lane, his second career Indy 500 triumph, having completed only , the shortest official race on record. Janet Guthrie became the first female driver to enter the Indianapolis 500. However, her team was underfunded, and she experienced numerous mechanical and engine problems during the month. While she managed to pass her rookie test, and ran numerous practice laps in multiple cars, she was unable to make an attempt to qualify. She would return with a successful effort a year later in 1977 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1974 Indianapolis 500
The 58th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana on Sunday, May 26, 1974. Johnny Rutherford, in his eleventh attempt, won the race from the 25th starting position, the farthest back since Louis Meyer in 1936. It was the first of his three Indy victories, and started a three-year stretch where he finished 1st-2nd-1st. The race was run relatively clean, with no major crashes or injuries, a sharp contrast from the tragic 1973 event. In order to increase safety, significant improvements were made to the track and cars. Wings were reduced in size, fuel tank capacity was reduced, and pop-off valves were added to the turbocharger plenums in order to reduce horsepower and curtail speeds. For the first time in Indy history, the race was scheduled for the Sunday of Memorial Day weekend. This ended the " never on a Sunday" policy previously held from 1911 to 1973. At the time, it was also the earliest calendar date (May 26) tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1972 Indianapolis 500
The 56th 500 Mile International Sweepstakes was held at the Indianapolis Motor Speedway in Speedway, Indiana, on Saturday, May 27, 1972. The race is notable in that for the first time, the cars were permitted bolt-on wings, and speeds climbed dramatically. Bobby Unser won the pole position at a then-remarkable speed of for four laps, breaking Peter Revson's track record of from 1971 by – the largest one-year track record increase in Indy history. The race average speed of was also a new record, which stood until 1984. Gary Bettenhausen led 138 laps until his car suffered ignition trouble on lap 176, and he coasted to the pits. Jerry Grant took over the lead, but pitted for a new tire and fuel on lap 188 in teammate Bobby Unser's pit - for which he was later disqualified. Bettenhausen's Penske teammate Mark Donohue won the race, after leading only the final 13 laps. It was owner Roger Penske's first of eighteen Indy 500 victories (as of 2019) and the first victory for a Mc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodyear Tire And Rubber Company
The Goodyear Tire & Rubber Company is an American multinational tire manufacturing company founded in 1898 by Frank Seiberling and based in Akron, Ohio. Goodyear manufactures tires for automobiles, commercial trucks, light trucks, motorcycles, SUVs, race cars, airplanes, farm equipment and heavy earth-moving machinery. It also makes bicycle tires, having returned from a break in production between 1976 and 2015. As of 2017, Goodyear is one of the top five tire manufacturers along with Bridgestone (Japan), Michelin (France), Continental AG, Continental (Germany) and MRF (company), MRF (India). The company was named after American Charles Goodyear (1800–1860), inventor of Vulcanization, vulcanized rubber. The first Goodyear tires became popular because they were easily detachable and required little maintenance. Though Goodyear had been manufacturing airships and balloons since the early 1900s, the first Goodyear Blimp, Goodyear advertising blimp flew in 1925. Today, it is one o ...

Longitudinal Engine
In automotive engineering, a longitudinal engine is an internal combustion engine in which the crankshaft is oriented along the long axis of the vehicle, front to back. Use This type of motor is usually used for rear-wheel drive cars, except for some Audi and SAAB models equipped with longitudinal engines in front wheel drive. In front-wheel drive cars a transverse engine is usually used. Trucks often have longitudinal engines with rear-wheel drive. For motorcycles, the use of a particular type depends on the drive: in case of a chain or belt drive a transverse engine is usually used, and with shaft drives a longitudinal engine. Longitudinal engines in motorcycles do have one disadvantage: the "tipping point" of the crankshaft tilts along the entire motorcycle to a greater or lesser degree when accelerating. This is partly resolved by having other components, such as the generator and the gearbox, rotate in the opposite direction to the crankshaft. Most larger, "premium" veh ...

Mid-engine
In automotive engineering, a mid-engine layout describes the placement of an automobile engine in front of the rear-wheel axles, but behind the front axle. History The mid-engine, rear-wheel-drive format can be considered the original layout of automobiles. A 1901 Autocar was the first gasoline-powered automobile to use a drive shaft and placed the engine under the seat. This pioneering vehicle is now in the collection of the Smithsonian Institution. Benefits Mounting the engine in the middle instead of the front of the vehicle puts more weight over the rear tires, so they have more traction and provide more assistance to the front tires in braking the vehicle, with less chance of rear-wheel lockup and less chance of a skid or spin out. If the mid-engine vehicle is also rear-drive the added weight on the rear tires can also improve acceleration on slippery surfaces, providing much of the benefit of all-wheel-drive without the added weight and expense of all-wheel-drive compon ...

Straight-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...
