http://en.wikipedia.org/wiki/Penske_Racing#Can-Am_Racing 1972–1973 Can-Am Porsche 917/30, in Stuttgart-Zuffenhausen Museum A rear 3⁄4 view of a 917/30 As the new rules for the 3-litre prototypes were not favourable to their existing low-weight, low-power Porsche 908, Porsche decided against developing a new high power engine that could keep up with the F1 designs of the competition's — at least in naturally aspirated form. In 1976 they would return to sport-prototype racing with the turbocharged Porsche 936 racecars after the engines were tested in Porsche 911 versions. After their successes with the 917 mainly in Europe, Porsche instead decided to focus on the North American markets and the Can-Am Challenge. For that series, larger and more powerful engines were needed. Although a 16-cylinder engine with about 750 hp (560 kW) was tested,[citation needed] a turbocharged 12-cylinder engine with comparable power output was ultimately used. The 917 chassis also had to be lengthened to accept the longer 16-cylinder engine, and drivers complained that this longer chassis did not handle as well. The turbocharged 850 hp (630 kW) 917/10 entered by Penske Racing won the 1972 series with George Follmer, after a testing accident sidelined primary driver Mark Donohue. This broke the five-year stranglehold McLaren had on the series. The further evolution of the 917, the 917/30 with revised aerodynamics, a longer wheelbase and an even stronger 5.4-litre engine with up to 1,580 horsepower (1,180 kW)[citation needed] won the 1973 edition winning all races but two when Charlie Kemp won the Mosport race and George Follmer won Road Atlanta and Mark Donohue won the rest. Most of the opposition was made of private 917/10 as McLaren, unable to compete against the 917 turbos, had already left the series to concentrate on Formula 1 and the Indy 500. The 917's domination, the oil crisis, and fiery tragedies like Roger Williamson's in Zandvoort pushed the SCCA to introduce a 3 miles per U.S. gallon maximum fuel consumption rule for 1974. Due to this change, the Penske 917/30 competed in only one race in 1974, and some customers retrofitted their 917/10 with naturally aspirated engines. The 917/30 was the most powerful sports car racer ever built and raced. The 5.374-litre 12 cylinder (90.0 x 70.4 mm) twin-turbocharged engine could produce 1,580 bhp (1,180 kW) in qualifying tune,[citation needed] with twin turbochargers run up to full boost, 39 psi (2.7 bar), though it usually raced with around 1,100 bhp (820 kW) at 7,800 rpm to preserve the engine. Weighing 1,800 lb (820 kg), giving it a power to weight of 1967.36 bhp/tonne in qualifying tune and 1369.68 bhp/tonne in race tune. The 917/30 dominated the Can-Am series during the 1973 season. The 917/30 could go from 0-62 mph (100 km/h) in 1.9 seconds, 0-100 mph (160 km/h) in 3.9 seconds, 0-200 mph (320 km/h) in 10.9 seconds, and on to a top speed of more than 260 mph (420 km/h).[citation needed] The high-level of performance and attendant fuel consumption of the engines, and ever increasing risk, has led to the 917/30 sometimes being cited as the car that killed Can-Am racing.[citation needed] The 917 was also the only championship winning car in Can Am not to be powered by Chevrolet. http://www.supercars.net/cars/5781.html http://www.supercars.net/Gallery?cmd=viewCarGallery&carID=5781&pgID=1

PORSCHE AUDI 917/10 CAN AM 1ST EDMONTON 1972 Origine 917 PA (PA pour Porsche+Audi) : grâce à l'encouragement de Vasek Polak, le distributeur californien de Porsche et d'Audi, Porsche décidait de construire une version groupe 7 de la toute nouvelle 917 groupe 5 pour participer à la Can-Am 1969. Cette voiture non-suralimentée n'allait obtenir qu'un podium mais elle fut déterminante pour la suite. La 917/10 non suralimentée de Jo Siffert arbore déjà la combinaison Porsche + Audi en 1971. Plus tard, les voitures étaient alignées par Porsche-Audi Inc. of USA. Il semblerait que commercialement Porsche voulait dissocier les agences Porsche et VW d'où l'îdée d'associer Porsche + Audi aux USA.
