Porsche 911 GT1
The Porsche 911 GT1 is a car designed and developed by German automobile manufacturer Porsche AG to compete in the GT1 class of sportscar racing, which also required a street-legal version for homologation purposes. The limited-production street-legal version developed as a result was named the 911 GT1 ''Straßenversion'' (''Street version''). History With the revival of international sportscar racing in the mid-1990s through the BPR Global GT Series (which then morphed into the FIA GT Championship) Porsche expressed interest in returning to top-level sportscar racing and went about developing its competitor for the GT1 category. Cars in this category were previously heavily modified versions of road cars, such as the McLaren F1 and the Ferrari F40. 911 GT2 Evo(Origin of Porsche GT1) Porsche originally modified the 993 GT2 into EVO version and homologated as a GT1, but it was completely uncompetitive compared to other supercars such as McLaren F1 and Ferrari F40.

Group GT1
Group GT1, also known simply as GT1, was a set of regulations maintained formerly by the Fédération Internationale de l'Automobile (FIA), for Grand Tourer racing. The category was first created in 1994, as the top class of the BPR Global GT Series, and was included in the 24 Hours of Le Mans. It fell under FIA regulation from 1997, after the BPR series came under the control of the FIA, becoming known as the FIA GT Championship. The category was dissolved at the end of 2011. The category may be split into four distinctive eras, from its debut in 1994–1996, 1997–1998, 2000–2009, 2010–2011. Early years (1994–1996) The class which was to become known as "GT1" was first debuted by the ACO (Automobile Club de l'Ouest) at the 1993 24 Hours of Le Mans, under the name Group GT. The class was first defined in the FIA Appendix J regulations, as ''Group GT'', in 1993. In 1994, following the collapse of the FIA World Sportscar Championship in 1992, BPR Global GT series was fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homologation (motorsport)
In motorsports, homologation is the type approval process through which a vehicle, a race track, or a standardised part is required to go for certification to race in a given league or series. The process of testing and certification for conformance to technical standards is usually known as type approval in English-language jurisdictions. The regulations and rules that must be met are generally set by the series's sanctioning body. The word is derived from Greek , . When a car loses the homologation form, that is, it becomes a historic vehicle, it can no longer be part of a competition and can only be used in historic competitions. Requirements In racing series that are "production-based", meaning that the vehicles entered in the series are based on production vehicles for sale to the public, homologation not only requires compliance with a racing series's technical guidelines (for example engine displacement, chassis construction, suspension design and such), but often i ...

Multi-valve
In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power. Multi-valve rationale Multi-valve engine design A multi-valve engine design has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for ''intake'' of air (and often fuel), and another for ''exhaust'' of combustion gases. Adding more valves increases valve area and improves the flow of intake and exhaust gases, thereby enhancing combustion, volumetric efficiency, and power output. Multi-valve geometry allows the spark plug to be ideally located within the combustion chamber for optimal flame propagation. Multi-valve engines tend to have smaller valves that have lower reciprocating mass, which can red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercooled
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines. Internal combustion engines Most commonly used with turbocharged engines, an intercooler is used to counteract the heat of compression and heat soak in the pressurised intake air. By reducing the temperature of the intake air, the air becomes denser (allowing more fuel to be injected, resulting in increased power) and less likely to suffer from pre-ignition or knocking. Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system. Many passenger cars use either ''front-mounted intercoolers'' loca ...

Water-cooled
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing ...

Porsche 993
The Porsche 993 is the internal designation for the Porsche 911 model manufactured and sold between January 1994 and early 1998 (model years 1995–1998 in the United States), replacing the 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 engineAutoTraderClassics.com — Article Finding Porsche's best road car — Porsche 911S vs 993. and only 20% of its parts were carried over from the previous generation. Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." Porsche's engineers devised a new light-alloy subframe with coil and wishbone suspension (an all new multi-link system, Weissach axle), putting behind the previous lift-off oversteer and making significant progress with the engine and handling, creating a more civilized ca ...

SARD MC8-R
The Toyota MR2 is a line of two-seat, mid-engined, rear-wheel-drive sports cars manufactured in Japan and marketed globally by Toyota from 1984 until 2007 over three generations: W10 (1984–1989), W20 (1989–1999) and W30 (2000–2007). It is Japan's first rear mid-engined production car. Conceived as a small, economical and sporty car, the MR2 employed straightforward design elements, including fully independent MacPherson strut front and rear suspensions, four-wheel disc brakes, and a transverse-mounted inline-four engine. The name MR2 stands for either "mid-ship run-about 2-seater" or "mid-engine, rear-wheel-drive, 2-seater". In French-speaking markets, the vehicle was renamed Toyota MR because the abbreviation "MR2" sounds like the profanity "merde" when spoken in French. Origins The MR2 derived from a 1976 Toyota design project with the goal of a car which would be enjoyable to drive, yet still provide good fuel economy – not necessarily a sports car.

Sports-prototype
A sports prototype, sometimes referred to as simply a prototype, is a type of race car that is used in the highest-level categories of sports car racing. These purpose-built racing cars, unlike street-legal and production-based racing cars, are not intended for consumer purchase or production beyond that required to compete and win races. Prototype racing cars have competed in sports car racing since before World War II, but became the top echelon of sports cars in the 1960s as they began to replace homologated sports cars. Current ACO regulations allow most sports car series to use two forms of cars: grand tourers (GT), based on street cars, and prototypes, which are allowed a great amount of flexibility within set rule parameters. In historic racing, they are often called "sports racing cars". Sometimes, they are incorrectly referred to as "Le Mans cars", whether they are competing in the Le Mans race or not. Types of sports prototypes Since the 1960s, various championships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dauer 962
The Dauer 962 Le Mans is a sports car based on the Porsche 962 Group C racing car. Built by German Jochen Dauer's Dauer Racing, a racing version of this car went on to win the 1994 24 Hours of Le Mans with the support of Porsche in LMGT1 group. The first road car debuted at the 1993 Frankfurt Auto Show. In total 13 cars were made. Changes to meet road regulations Dauer Racing (now Dauer Sportwagen) produced the 962 Le Mans from stripped down Porsche 962 bodies for modification. Components of the bodywork were replaced with slightly revised carbon fiber and kevlar panels. The under tray was replaced with a flat version for better stability at high speeds. A second seat and leather upholstery were installed in the cramped cockpit, as well as a video screen for DVD playback in later years. A small compartment was added to the front of the car to carry luggage. A hydraulic suspension system was also added to meet German ride height requirements for street cars. Specifications ...

SARD MC8-R
The Sard MC8-R was a modified and lengthened version of the Toyota MR2 (SW20) built for GT racing by Toyota's SARD (Sigma Advanced Research Development) works team. SARD heavily modified the original MR2 frontal chassis deriving with custom rear chassis in order to fit a twin-turbo version of the 4.0-liter 1UZ-FE V8 producing . This is the first car which only using the frontal chassis of production car was effectively a purpose-built semi-sports-prototype that successfully got GT1 homologation. The MC8-R lacked pace and was very unreliable in that makes it often at the bottom of the race and even the 'traditional' GT1 Toyota Supra also faster than it and let alone with the McLaren F1 and Ferrari F40. Since the custom rear chassis and numerous dedicated components will lead to significant differences from the original MR2, a homologation car had to be built. SARD built one MC8 road car in order to meet homologation requirements. This car disappeared from public eye within a yea ...
