Formula Holden
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 Commodore (VN). 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
