Car tuning WikipediaAuto tuning redirects here. For the principle of automatic correction, see Self tuning. For the audio processor, see Auto Tune. Car tuning is modification of the performance or appearance of a vehicle. For actual tuning in the sense of automobiles or vehicles, see engine tuning. Most vehicles leave the factory set up for an average drivers expectations and conditions. Tuning, on the other hand, has become a way to personalize the characteristics of a vehicle to the owners preference. Cars may be altered to provide better fuel economy, produce more power, or to provide better handling and driving. Car tuning is related to auto racing, although most performance cars never compete. Tuned cars are built for the pleasure of owning and driving. Exterior modifications include changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, spoilers, splitters, air vents and light weight wheels. Cars have always been subject to after company modification. The golden age of car tuning was the decades between World War II and the beginning of air pollution restrictions. Both moderate and radical modification have been commemorated in the popular songs Hot Rod Race and Hot Rod Lincoln. The names of Abarth and Cooper appear on models styled after the cars they modified. Cosworth went, with support from Ford, from modifying Ford of Britain. English. Flathead engines for Lotus Sevens to dominating Formula One racing. In the 1. 97. 0s and 1. Japanese performance cars were never exported outside the Japanese domestic market. In the late 1. 98. Grey import vehichles of Japanese performance cars, such as the Nissan Skyline,1123 began to be privately imported into Western Europe and North America. In the United States, this was in direct contrast to the domestic car production around the same time, where there was a very small performance aftermarket for domestic compact and economy cars the focus was instead on sporty cars such as the Ford Mustang and Chevrolet Corvette, or on classic muscle cars. Because of their light weight and the increasing availability of low prise tuning equipment, economy and compact cars exhibit high performance at a low cost in comparison to dedicated sports cars. As professional sporting and racing with such vehicles increased, so did recreational use of these vehicles. Drivers with little or no automotive, mechanical, or racing experience would modify their vehicles to emulate the more impressive versions of racing vehicles, with mixed results. Areas of modificationeditThe essence of modification of a tuner car is an attempt to extract the greatest possible performanceor the appearance of high performancefrom the base motor vehicle through the addition, alteration or outright replacement of parts. Although this largely involves modifying the engine and management systems of the vehicle to increase the power output, additional changes are often required to allow the vehicle to handle this power, including stiffened suspension, widened tires, better brakes, improved steering and transmission modifications such as the installation of a short shifter. Although largely invisible from outside the vehicle, certain modifications such as low profile tires, altered suspension, and the addition of spoilers can change the overall appearance of the car, as well as adding downforce to increase traction. A stock audio system is one specified by the manufacturer when the vehicle was built in the factory. A custom audio installation can involve anything from the upgrade of the radio to a full blown customization based around the audio equipment. Events are held where entrants compete for the loudest, highest quality reception or most innovative sound systems. Some common modifications include higher quality speakers and sub woofers, amps, a better wiring system, etc. InterioreditAll cars competing in each class must adhere to a strict set of regulations. As in some well known racing events, like NASCAR and NHRA, sanctioned events often require a minimum vehicle weight. In such cases the interior is stripped, and the required weight is achieved by adding ballast that allows precise control over weight distribution. Along with weight requirements, safety requirements are present. Requirements differ for different classes. Roll cages, fire extinguishers, reinforced bucket seats, seat harnesses, and the like are some of the required safety modifications. Roll cages may be difficult to install when the original equipment interior is present. Some tuners will have gutted interiors, or omit features that many ordinary drivers would find desirable or necessary, such as audio systems, air conditioning and soundproofing in order to reduce vehicle weight. Engine tuningeditEngine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, Mass air flow Volume air flow, etc. Modern engines employ the use of an ECM to provide the best balance between performance and emissions. Via the OBD communications protocol, the electronically controlled aspects of the engine can be modified in the process known as mapping. Mapping can either be performed by changing the software within the ECU chip tuning via firmware modification, or by providing false data via plug in hardware. Mechanical components can also be replaced, such as turbochargers or superchargers. Other standalone engine management systems are available. These systems replace the factory computer with one that is user programmable. Improper, incorrect and poorly executed engine modifications can have a detrimental effect on performance. Emoticons For Yahoo Email. Mechanical and electrical components will suffer or simply fail as a result. An example would be the use of an air compressor such as a turbocharger to increase the volume of air used in power stroke of the otto cycle. In a typical chemical reaction, the air fuel ratio must be a minimum of 1. Stoichiometry. If higher ratios are used,clarification needed higher pressures and temperatures are observed in the cylinders, which can quickly push an engine beyond its intended design limits. Neglecting such operating parameters can lead to premature failure, such as warped cylinder heads and walls temperature related, disintegrated piston rings, cracked or bent connecting rods and crankshafts excessive amount of torque applied, total cooling system failure, engine fire, engine detonation, engine seizing, and even blowouts. This can all lead to very expensive repairs, as well as being very dangerous. Suspension tuningeditSuspension tuning involves modifying the springs, shock absorbers, swaybars, and other related components of a vehicle. Shorter springs offer greater stiffness and a lower center of gravity at the possible cost of unwanted changes of suspension geometry. Stiffer shock absorbers improve the dynamic weight shifting during cornering and normally have shorter internals to stop them from bottoming out when shorter springs are used.
