Restrictor Plates
A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles (e.g., motorcycles) for insurance purposes, but mainly in automobile racing, to limit top speed to provide equal level of competition, and to lower costs; insurance purposes have also factored in for motorsports. Racing series A few top classes like Formula One limit only the displacement and air intake mouth dimension. However, in 2006 air restrictors (as well as rev limiters) were used by Scuderia Toro Rosso to facilitate the transition to a new engine formula. Many other racing series use additional air restrictors. * Formula 3, 2000cc, 215 hp * Formula SAE, 710cc, 20 mm restrictor. * Deutsche Tourenwagen Masters, 4000cc, 470 hp * FIA GT Championship (now FIA GT1 World Championship) and other series using FIA GT regulations * Le Mans Prototypes used in American Le Mans Series and Le Mans Series h ...

Fédération Internationale Du Sport Automobile
Fédération Internationale du Sport Automobile (FISA) was the sport governing body for motor racing events, in particular Formula One. The organization's origins dated from 1922, when the Fédération Internationale de l'Automobile (FIA) delegated the organization of automobile racing to the Commission Sportive Internationale (CSI), which lasted until 1978 when Jean-Marie Balestre took over the reins and it was renamed FISA. A restructuring of the FIA in 1993 led to the disappearance of the FISA, putting motor racing under the direct management of the FIA.

NASCAR Cup Series
The NASCAR Cup Series is the top racing series of the National Association for Stock Car Auto Racing (NASCAR). The series began in 1949 as the Strictly Stock Division, and from 1950 to 1970 it was known as the Grand National Division. In 1971, when the series began leasing its naming rights to the R. J. Reynolds Tobacco Company, it was referred to as the NASCAR Winston Cup Series (1971–2003). A similar deal was made with Nextel in 2003, and it became the NASCAR Nextel Cup Series (2004–2007). Sprint acquired Nextel in 2005, and in 2008 the series was renamed the NASCAR Sprint Cup Series (2008–2016). In December 2016, it was announced that Monster Energy would become the new title sponsor, and the series was renamed the Monster Energy NASCAR Cup Series (2017–2019). In 2019, NASCAR rejected Monster's offer to extend the current naming rights deal beyond the end of the season. NASCAR subsequently announced its move to a new tiered sponsorship model beginning with the 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rev Limiter
A rev limiter is a device fitted in modern vehicles that have internal combustion engines. They are intended to protect an engine by restricting its maximum rotational speed, measured in revolutions per minute (RPM). Rev limiters are pre-set by the engine manufacturer. There are also aftermarket units where a separate controller is installed using a custom RPM setting. A limiter prevents a vehicle's engine from being pushed beyond the manufacturer's limit known as the redline (literally the red line marked on the tachometer). At some point beyond the redline, engine damage may occur. Operation Limiters usually work by shutting off a component necessary for the combustion processes to occur. Compression-ignition engines use mechanical governors or limiters to shut off electronic fuel injectors. A spark-ignition engine may also shut off fuel or stop the spark ignition and some just reduce the engine's power by changing the spark timing. In the case of an automatic transmissio ...

Power (physics)
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called ''activity''. Power is a scalar quantity. Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction force on the wheels, and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element. Definition Power is the rate with respect to time at which work is done; it is the time derivative of work: P =\frac where is power, is work, and is time. If a constant force F is applied throughout a distance x, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Group N
In relation to international motorsport governed by the FIA, Group N refers to regulations providing 'standard' large scale series production vehicles for competition. They are limited in terms of modifications permitted to the standard specification by the manufacturer making them a cost effective method of production vehicle motorsport. Often referred to as the "showroom class", Group N contrasts with Group A which has greater freedom to modify and tune the cars to be more suitable to racing. Both Groups may have the same or similar models homologated by a manufacturer. Group N was introduced by the FIA in 1982 to replace the outgoing Group 1 as "''standard touring cars''". At this time there weren't specific formula for production racing cars in competition. The World Rally Championship (WRC) for example only permitted Groups A, B and N cars to compete (Group B was banned from 1987). It wasn't until 1997 that the World Rally Car formula was introduced and other specific fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Rally Car
A World Rally Car is a racing automobile built to the specific regulations set by the Fédération Internationale de l'Automobile (FIA) and designed for competition in the World Rally Championship (WRC). The cars were introduced in 1997 as a replacement for Group A regulations used in the manufacturers' championship, and were replaced by Group Rally1 in 2022. Regulations 1997–2010 Between 1997 and 2010, the regulations mandated that World Rally Cars must have been built upon a production car with a minimum production run of 2500 units. A number of modifications could be made including increasing the engine displacement up to 2.0L, forced induction (including an anti-lag system), addition of four wheel drive, fitment of a sequential gearbox, modified suspension layout and attachment points, aerodynamic body modifications, weight reduction to a minimum of 1230 kg and chassis strengthening for greater rigidity. The maximum width was set at 1770 mm while front and rear t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Supercharged
In an internal combustion engine, a supercharger compresses 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 supercharger is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gasses. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and/or increase power outputs. D ...
