The last holdouts formed CAT (Can-Am Teams) in 1986 to take over sanctioning as part of the SCCA. Two plans emerged, one keeping the Formula 5000-based cars, and others who favored using old CART machines. Bill Tempero led the Indy-style effort. CAT held one race in 1986, and folded after a short 1987 season. Tempero broke off and started his Indy car series in 1988, with the cars powered by 5.9-litre stock block Chevrolet engines. As the series began to slowly gain competitors, the teams were allowed to run a choice of two powerplants. The aforementioned V-8 5.9-liter Chevy stockblock, or a V-6 (best known as the Buick/Menard) in turbocharged or normally aspirated configuration. An equivalency formula was determined to provide for competitive balance amongst the different engine combinations. The chassis utilized consisted of used March, Lola, Reynard, Eagle, and Penske from CART competition. In later years, G-Force and Dallara cars from IRL competition were also used. 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「American Indycar Series」の詳細全文を読む スポンサード リンク
