Graining (motorsport)
The following is a glossary of terminology used in motorsport, along with explanations of their meanings. 0–9 ;1–2 finish: When two vehicles from the same team finish first and second in a race. Can be extended to 1–2–3 or 1–2–3–4, etc. depending on a combination of racing series and team size. ;107% rule: Often used in Formula One or other racing series, it is a rule where the driver must qualify the car within 107% of the polesitter's time to be allowed to compete. Variations of this may be used to monitor drivers and warn them to reach the required pace or be parked (disqualified). Similarly, the IndyCar Series uses a 105% rule, and NASCAR has a 115% rule, mainly for performance on track, though IndyCar and NASCAR often adjust the threshold for tracks with very abrasive surfaces (such as Atlanta Motor Speedway) where lap times can be considerably faster with less worn tires. ;200 MPH Club: A lifetime "membership" awarded by the SCTA or another sanctioning ...

Motorsport
Motorsport, motorsports or motor sport is a global term used to encompass the group of competitive sporting events which primarily involve the use of motorized vehicles. The terminology can also be used to describe forms of competition of two-wheeled motorised vehicles under the banner of motorcycle racing, and includes off-road racing such as motocross. Four- (or more) wheeled motorsport competition is globally governed by the Fédération Internationale de l'Automobile (FIA); and the Fédération Internationale de Motocyclisme (FIM) governs two-wheeled competition. Likewise, the Union Internationale Motonautique (UIM) governs powerboat racing while the Fédération Aéronautique Internationale (FAI) governs air sports, including aeroplane racing. All vehicles that participate in motorsports must adhere to the regulations that are set out by the respective global governing body. History In 1894, a French newspaper organised a race from Paris to Rouen and back, star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprint Car Racing
Sprint cars are high-powered open-wheel race cars, designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Sprint car racing is popular primarily in the United States and Canada, as well as in Australia, New Zealand, and South Africa. Sprint cars have very high power-to-weight ratios, with weights of approximately (including the driver) and power outputs of over , which give them a power-to-weight ratio besting that of contemporary F1 cars. Typically, they are powered by a naturally aspirated, methanol-injected overhead valve American V8 engine with a displacement of 410 cubic inches (6.7L) and capable of engine speeds of 9000 rpm. Depending on the mechanical setup (engine, gearing, shocks, etc.) and the track layout, these cars can achieve speeds in excess of . A lower-budget and very popular class of sprint cars uses 360-cubic-inch (5.9L) engines that produce up to 775 horsepower. Sprint cars do not utilize a transmission but have an ...

PJ1 TrackBite
PJ1 TrackBite (formerly known as VHT TrackBite or simply VHT) is a custom formulated synthetic resin, typically black in color, used in drag racing to either increase the traction of a car's tires or as a sealer for newly ground and/or resurfaced race tracks. It stays sticky for weeks, has fire-retardant properties and is hydrophobic. It has been used in professional racing since 1972. The TrackBite that the National Hot Rod Association uses, is yellowish in color and is diluted with methanol for optimal effect. The compound originated as a high temperature coating made for NASA by the Sperex Corporation. VHT, a brand owned by Sperex, began offering it for sale commercially. It was taken up by drag racers, and Sperex soon began producing formulations specially made for the sport. Sperex was purchased in 1989 by businessman P. J. Harvey and is now part of PJH Brands. PJ1 in Non-Drag Racing Applications Oval tracks also use TrackBite to provide extra traction in the corners of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bleach
Bleach is the generic name for any chemical product that is used industrially or domestically to remove color (whitening) from a fabric or fiber or to clean or to remove stains in a process called bleaching. It often refers specifically, to a dilute solution of sodium hypochlorite, also called "liquid bleach". Many bleaches have broad spectrum bactericidal properties, making them useful for disinfecting and sterilizing. They are used in swimming pool sanitation to control bacteria, viruses, and algae, and in many places where sterile conditions are required. They are also used in many industrial processes, notably in the bleaching of wood pulp. Bleaches also have other minor uses like removing mildew, killing weeds, and increasing the longevity of cut flowers. Bleaches work by reacting with many colored organic compounds, such as natural pigments, and turning them into colorless ones. While most bleaches are oxidizing agents (chemicals that can remove electrons from othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Restrictor Plate
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 ...

Stock Car Racing
Stock car racing is a form of automobile racing run on oval tracks and road courses measuring approximately . It originally used production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originated in the southern United States; the world's largest governing body is the American NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Australia, Canada, New Zealand, Mexico, Brazil and the United Kingdom also have forms of stock car racing. Top-level races typically range between in length. Top-level stock cars exceed at speedway tracks and on superspeedway tracks such as Daytona International Speedway and Talladega Superspeedway. Contemporary NASCAR-spec top-level cars produce maximum power outputs of 860–900 hp from their naturally aspirated V8 engines. In October 2007 American race car driver Russ Wicks set a speed record for stock cars in a 2007-season Dodge Charger buil ...

The Big One (motorsport)
The Big One is a phrase describing any crash usually involving five or more cars in NASCAR, ARCA, and IndyCar racing. It is most commonly used at Daytona International Speedway and Talladega Superspeedway, although occasionally seen at other tracks as well, such as Dover International Speedway and Watkins Glen International. Coining the phrase Until the 2000s, massive crashes were referred to as "major"ESPN SpeedWorld – 1989 Winston 500, May 7, 1989,CBS Sports – 1992 Daytona 500, February 16, 1992, or "terrific"ESPN SpeedWorld – 1990 Pepsi 400, July 7, 1990, crashes. By the mid-1990s, competitors and media began taking note of the multi-car wrecks at Daytona and Talladega. In 1997, Dale Earnhardt described a final-lap crash at the 1997 Pepsi 400 as "the Big Wreck". News articles began using the term "Big Wreck" to describe such crashes in 1998, and by 1999, its use was widespread. Drivers began to openly admit they were apprehensive of its possibility.

Electric Eye
An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam. The device does not provide an image; only presence of light is detectable. Visible light may be used, but infrared radiation conceals the operation of the device and typically is used in modern systems. Originally, systems used lamps powered by direct current or the power line alternating current frequency, but modern photodetector systems use an infrared light-emitting diode modulated at a few kilohertz, which allows the detector to reject stray light and improves the range, sensitivity and security of the device. Examples Highway vehicle counter * In the 1930s, an electric eye vehicle counter was introduced in the US using two IR lamps set apart so that only cars and not pedestrian ...

Autotesting
Autotesting involves a series of tests, generally around traffic cones, to measure precision driving skill. The tests often include stopping with the front and rear wheels straddling a line, and always end stopping in a garage (usually marked out with cones). Sections of each test are usually completed in reverse. Cars involved can be standard road cars or ones specially built for autotest. In either case, the sport is cheap, with entries to events usually costing between £8 and £25.{{citation needed, date=June 2017 Autotests can take place on either grass or hard surface. Grass Autotests are popular for club events as they are more gentle on tires and transmissions. Many Clubs run their Grass autotests without any reversing. Championship Autotests in the UK are normally on a hard surface. Each event consists of between three and six tests, with each test completed twice with the faster of the two counting for the results. The tests are timed with a stopwatch, with penal ...
