Porsche 911 GT2
The Porsche 911 GT2 is a high-performance, track-focused sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and then since 2010 as the GT2 RS. It is based on the Porsche 911 Turbo, 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine enhancements, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of an all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 (now GT2 RS) is the most expensive and fastest model among the Porsche 911, 911 lineup. __TOC__ 993 generation The Porsche 993, 993 GT2 was initially built in order to meet homologation (motorsport), homologation requirements for FIA GT2 European Championship, GT2 class racing. Because the cars were built to meet the GT2 class regulations, the road cars were named accordingly (but badged as the 911 GT). The ...

Porsche
Dr. Ing. h.c. F. Porsche AG, usually shortened to Porsche (; see below), is a German automobile manufacturer specializing in luxury, high-performance sports cars, SUVs and sedans, headquartered in Stuttgart, Baden-Württemberg, Germany. The company is owned by Volkswagen AG, a controlling stake of which is owned by Porsche Automobil Holding SE, usually shortened to Porsche SE. Porsche's current lineup includes the 718, 911, Panamera, Macan, Cayenne and Taycan. The origins of the company date to the 1930s when German Bohemian automotive engineer Ferdinand Porsche founded Porsche with Adolf Rosenberger, a keystone figure in the creation of German automotive manufacturer and Audi precursor Auto Union, and Austrian businessman Anton Piëch, who was, at the time, also Ferdinand Porsche's son in law. In its early days, it was contracted by the German government to create a vehicle for the masses, which later became the Volkswagen Beetle. After World War II, when Ferd ...

Twin-turbo
Twin-turbo is a type of turbo layout in which two turbochargers are used to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. The ga70 1ggte was the first inline 6 twin turbo in the world. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel In a parallel configuration, two equally-sized turbochargers each receive half of the exhaust gases. Some designs combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stroke (engine)
In the context of an internal combustion engine, the term stroke has the following related meanings: * A phase of the engine's cycle (e.g. compression stroke, exhaust stroke), during which the piston travels from top to bottom or vice versa. * The type of power cycle used by a piston engine (e.g. two-stroke engine, four-stroke engine). * "Stroke length", the distance travelled by the piston during each cycle. The stroke length, along with bore diameter, determines the engine's displacement. Phases in the power cycle Commonly used engine phases or strokes (i.e. those used in a four-stroke engine) are described below. Other types of engines can have very different phases. Induction-intake stroke The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine. It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion ...

Bore (engine)
In a piston engine, the bore (or cylinder bore) is the diameter of each cylinder. Engine displacement is calculated based on bore, stroke length and the number of cylinders: displacement = The stroke ratio, determined by dividing the bore by the stroke, traditionally indicated whether an engine was designed for power at high engine speeds ( rpm) or torque at lower engine speeds. The term "bore" can also be applied to the bore of a locomotive cylinder or steam engine pistons. In steam locomotives The term bore also applies to the cylinder of a steam locomotive or steam engine. Bore pitch Bore pitch is the distance between the centerline of a cylinder bore to the centerline of the next cylinder bore adjacent to it in an internal combustion engine. It's also referred to as the "mean cylinder width", "bore spacing", "bore center distance" and "cylinder spacing". The bore pitch is always larger than the inside diameter of the cylinder (the bore and piston diameter) sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engine Displacement
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole e ...

Air-cooled Engine
Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps. Air-cooled engines are widely seen in applications where weight or simplicity is the primary goal. Their simplicity makes them suited for uses in small applications like chainsaws and lawn mowers, as well as small generators and similar roles. These qualities also make them highly suitable for aviation use, where they are widely used in general aviation aircraft and as auxiliary power units on larger aircraft. Their simplicity, in particular, also makes them common on motorcycles. Introduction Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fl ...

FIA GT2 European Championship
The FIA GT Championship was a sports car racing series organized by the Stéphane Ratel Organisation (SRO) at the behest of the Fédération Internationale de l'Automobile (FIA). The championship was mostly concentrated in Europe, but throughout the years has visited other continents including Asia and South America. At the end of 2009, the championship was replaced by the FIA GT1 World Championship, which morphed into the FIA GT Series for 2013. Regulations FIA currently defines several categories of GT cars with the top two specifications being GT1, or Grand Touring Cars, and GT2, or Series Grand Touring Cars. Each category has an annual driver champion, team champion, and manufacturer champion. Both categories are based on production road car designs, which must be produced in a minimum quantity of 25 examples to qualify. Both types may undergo significant modifications from the road car they are based on, but GT1 allows the use of exotic materials, better aerodynamics, lar ...

Homologation (motorsport)
In motorsport, homologation is a testing and certification process for vehicles, circuits, and related equipment for conformance to technical standards, usually known as type approval in English-language jurisdictions. It confirms conformity to standards or categorisation criteria typically set by the sporting authority. At international and supra-national level, the Fédération Internationale de l'Automobile, FIA and Fédération Internationale de Motocyclisme, FIM mandate what must be homologated, the FIA in its International Sporting Code and appendices. National sporting authorities such as Motorsport UK must adhere to these rules but may enforce additional or specific homologation rules applicable to their series or jurisdiction, however, unaffiliated series may set their own requirements. The word homologation is derived from Greek language, Greek , . Requirements "Production-based" racing series require that racing vehicles are based on production vehicles for sale to th ...

Porsche 993
The Porsche 911, internally type 993, is the fourth generation of the 911 model of Porsche sports car, manufactured and sold between 1994 and 1998 (model years 1995–1998 in the United States), replacing the 911, type 964. Its discontinuation marked the end of air-cooled 911 models. The 993 was much improved over and quite different from its predecessor. According to Porsche, "every part of the car was designed from the ground up, including the engine"AutoTraderClassics.com — Article Finding Porsche's best road car — Porsche 911S vs 993. but nevertheless "only 20% of its parts were carried over from the prior 911". Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." The external design of the Porsche 993 was penned by English designer Tony Hatter. It retained the core cabin and body shell architecture of the 964 and prior 911 model iterations, but exterior panels were revised with much more flared ...
