BMW GTP
The BMW GTP was an IMSA GTP sports racing car built by BMW in 1986. Four March 86Gs were rebuilt by BMW North America into the BMW GTP, and fitted with a Formula One-derived BMW M12/14 turbocharged straight-four engine. Like the F1 cars that used the M12 engine, the BMW GTPs were fragile, and often retired from races; however, when they did complete a race, the BMW GTP was usually classified in the overall top ten. For longevity purposes in endurance races, it usually ran around . However, in qualifying trim, was feasible; combined with the aerodynamics the 220+mph top speed was limited only by gearing. Design and development In 1986, BMW North America decided to enter the GTP category of the IMSA GT Championship. Using a modified March 86G chassis (the company had purchased four of these), a modified version of the turbocharged BMW M12/14 Formula One engine was fitted. Unlike the 1.5-litre capacity used in Formula One, the GTP used a 2-litre variant of the engine, capabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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" ve ...

12 Hours Of Sebring
The 12 Hours of Sebring is an annual motorsport endurance race for sports cars held at Sebring International Raceway, on the site of the former Hendricks Army Airfield World War II air base in Sebring, Florida, US. The event is the second round of the WeatherTech SportsCar Championship and in the past has been a round of the now defunct World Sportscar Championship, IMSA GT Championship and American Le Mans Series. In 2012, the race was the opening event of the FIA World Endurance Championship. History The track opened in 1950 on an airfield and is a road racing course styled after those used in European Grand Prix motor racing. The first race was a six-hour race on New Year's Eve 1950. The winning car is currently on display at the Edge Motor Museum in Memphis, Tennessee. The next race held 14 months later as the first 12 Hours of Sebring. The race is famous for its "once around the clock" action, starting during the day and finishing at night. From 1953 to 1972 the 12 Hour ...

Grand Prix Of Miami (sports Car Racing)
The Trans-Am Series, Rolex Sports Car Series, and American Le Mans Series have all held races in the Miami area. IMSA Promoter Ralph Sanchez brought auto racing to the Miami area in 1983. A course at Bicentennial Park featured the IMSA GT Championship and the inaugural Grand Prix of Miami. A circuit was laid out on the park roads and Biscayne Boulevard. The 1983 event was a failure both competitively and financially. A severe rainstorm flooded the circuit, and stopped the race after less than one-sixth of the distance was completed. Despite not being obligated to, Sanchez decided to pay the entire purse to the competitors, absorbing a $1.3 million loss but earning great respect from the racing fraternity. A year later, the event returned, and grew into a huge success. IMSA races were held at the first Bicentennial Park from 1983 until 1985. In 1986, the event moved to a new layout, also located at Bicentennial Park. The new Bicentennial Park circuit was a semi-permanent layou ...

Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolutions Per Minute
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is a unit of rotational speed or rotational frequency for rotating machines. Standards ISO 80000-3:2019 defines a unit of rotation as the dimensionless unit equal to 1, which it refers to as a revolution, but does not define the revolution as a unit. It defines a unit of rotational frequency equal to s−1. The superseded standard ISO 80000-3:2006 did however state with reference to the unit name 'one', symbol '1', that "The special name revolution, symbol r, for this unit is widely used in specifications on rotating machines." The International System of Units (SI) does not recognize rpm as a unit, and defines the unit of frequency, Hz, as equal to s−1. :\begin 1~&\text &&=& 60~&\text \\ \frac~&\text &&=& 1~&\text \end A corresponding but distinct quantity for describing rotation is angular velocity, for which the SI unit is the ra ...

IMSA GT Championship
IMSA GT was a sports car racing series organized by International Motor Sports Association. Races took place primarily in the United States, and occasionally in Canada. History The series was founded in 1969 by John and Peggy Bishop, and Bill France, Sr. Racing began in 1971, and was originally aimed at two of FIA's stock car categories, running two classes each; the GT ( Groups 3 and 4) and touring (Group 1 and 2) classes. The first race was held at Virginia International Raceway; it was an unexpected success, with both the drivers and the handful of spectators who attended. For the following year, John Bishop brought in sponsor R. J. Reynolds, and in 1975 introduced a new category: All American Grand Touring (AAGT). In 1977, the series went through a series of major changes. IMSA permitted turbocharged cars to compete for the first time, as well as introducing a new category: GTX, based on Group 5 rules. In 1981, after Bishop decided to not follow FIA's newly introduced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula One
Formula One (also known as Formula 1 or F1) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The World Drivers' Championship, which became the FIA Formula One World Championship in 1981, has been one of the premier forms of racing around the world since its inaugural season in 1950. The word ''formula'' in the name refers to the set of rules to which all participants' cars must conform. A Formula One season consists of a series of races, known as ''Grands Prix'', which take place worldwide on both purpose-built circuits and closed public roads. A points system is used at Grands Prix to determine two annual World Championships: one for drivers, the other for constructors. Each driver must hold a valid Super Licence, the highest class of racing licence issued by the FIA. The races must run on tracks graded "1" (formerly "A"), the highest grade-rating issued ...

Sports Racing Car
Sports car racing is a form of motorsport road racing which utilises sports cars that have two seats and enclosed wheels. They may be purpose-built prototypes or grand tourers based on road-going models. Broadly speaking, sports car racing is one of the main types of circuit auto racing, alongside open-wheel single-seater racing (such as Formula One), touring car racing (such as the British Touring Car Championship, which is based on 'saloon cars' as opposed to the 'exotics' seen in sports cars) and stock car racing (such as NASCAR). Sports car races are often, though not always, endurance races that are run over relatively large distances, and there is usually a larger emphasis placed on the reliability and efficiency of the car as opposed to outright speed of the driver. The FIA World Endurance Championship is an example of a sports car racing series. A type of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this style is often associated ...
