Formula Holden was an Australian open wheel racing category introduced in 1989. ==History== Known during its development as Formula Australia, it was initially for chassis constructed from aluminium only, running a 3.8 litre Buick V6 engine as it was then utilised in the new versions of the Holden VN Commodore. Many of the engines used in the category were built by Perkins Engineering, who normally built Group A Holden Commodores and V8 race engines for privateer touring car teams, as well as company owner, multiple Bathurst 1000 winner and ex-Formula One driver Larry Perkins. Early in 1990, Perkins was reported as saying that his Formula Holden engines were putting out approximately . To make the V6 engines suitable for racing (in the Commodore road cars the engines developed ), a number of specialised parts were supplied by original series sponsor ACL (Automotive Components Limited). Second-hand Formula 3000 chassis were targeted immediately as a cheap source of cars in addition to local constructors, and under CAMS rules, all cars had to be at least one year old. Formula Holden also used a Dunlop control tyre in its early years. For the 1992 season cars constructed from carbon fibre were allowed. In 2006 an engine upgrade was made available to the 3.6 litre Alloytec V6 engine, although take-up of the Alloytec V6 was far from universal. The engines were usually mounted in ex- Formula 3000 chassis, a large number of which were sourced from the Formula Nippon championship in Japan, but also included cars from other sources and a few specifically designed for the class, like the Australian designed Cheetah, Elfin, Spa (designed by F1 designer Gary Anderson), and the Shrike cars which were designed and built by technical students at the Croydon Park Institute of TAFE in Adelaide. Formula Holden was in essence a budget form of Formula 3000, the main difference being the engines. As detailed, Formula Holden ran the 3.8 Litre Holden V6 engines. Formula 3000, as its name suggests, ran 3.0 Litre V8 engines including the Cosworth DFV and later the popular Mugen-Honda which were capable of producing over . As a guide to the speed difference between the two categories, television commentator turned race driver Neil Crompton tested a Mugen powered Dome Japanese F3000 car at the Phillip Island Circuit in early 1990. The Dome lapped the circuit in approximately 1:18 while two months later for the opening round of the 1990 Australian Drivers' Championship, the fastest qualifier was the Ralt RT21 of Simon Kane who qualified in 1:26.97.〔(1990 Phillip Island Raceway Dunlop Tyre Testing )〕〔(Phillip Island 1990 Formula Holden )〕 From its inception in 1989 until 2004 the formula was used to determine the winner of the Australian Drivers' Championship for the CAMS Gold Star, replacing Formula 2 which had been the Gold Star category in 1987 and 1988. From 2005 this title was moved to the Australian Formula 3 Championship. The first ever Formula Holden race was held at the Mallala Motor Sport Park in South Australia. Mark McLaughlin driving an Elfin FA891, designed and built at the Elfin factory in nearby Adelaide, won the opening race from former dual Australian Formula 2 champion Peter Glover in an Australian designed Cheetah Mk.9 with television commentator turned race driver Neil Crompton third in his Ralt RT21. During the race, television broadcaster Channel 7 claimed that a Formula Holden engine would cost approximately A$9,700..〔(Formula Holden first ever race )〕 From 1991 to 1995 the category was officially known as Formula Brabham 〔Once bitten......twice as good!, Official Programme, Transurban Australian Grand Prix, Melbourne, 7 to 10 March 1996, pages 104-106〕 in honour of Australia's first ever Formula One World Champion Sir Jack Brabham, the only person in history to win the World Championship in a car of his own design in . Sir Jack acted as the category patron for five seasons. In 1996 the name reverted to Formula Holden 〔 and from the 2003 season the category was officially called "Formula 4000 powered by Holden". The formula was also used for a 1993 Pan-Pacific series, several New Zealand Grands Prix, and Tasman Cup (Australia versus New Zealand) summer series. It was also proposed to be used for an Asian series based in China. With numbers dropping and the increasing prominence of Formula 3, the class was dropped by the CAMS sanctioning body after the 2005 season. In 2006, the category was run as part of the Australian Motor Racing Series under the sanctioning of the Australian Auto Sport Alliance (AASA) and at times the regular Formula 4000 field was complemented by vehicles competing in the new Oz BOSS category for open wheel racing cars. In 2007 numbers had dropped to the point they could no longer form races by themselves and were amalgamated into the OzBOSS category. As part of this amalgamation, the cars themselves were re-badged again as Formula 3000V6. The drivers in the series in the 2000s were a mix of older drivers who owned their own cars, or very young Oceanic or South Asian drivers looking to make a name for themselves on the international scene. Although technically using cars just a step below Formula One, the lack of competition in the series means that drivers tended to progress from Formula 4000 to a minor series in Europe (Will Power - British Formula 3) or North America (Scott Dixon - Indy Lights). Alternatively drivers moved to any of the Australian sedan based championships such as V8 Supercars or Australian GT. From 1 January 2012, Formula Holden cars with a competition history established prior to 31 December 1991 are eligible to compete in Group R "Historic Racing & Sports Racing Cars (post-1977)".〔 (CAMS Bulletin Number: B11/127 ) Retrieved on 10 April 2012〕 However, cars constructed with a full carbon tub are specifically excluded from this Group.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Formula Holden」の詳細全文を読む スポンサード リンク
