His first task was successful and the Porsche 917 dominated the event in 1970 as well as in 1971, the first year Singer attended the great race.Singer was involved in the 911 Carrera RSR and RSR Turbo 2.1 from 1972 to 1974 Singer was then given the task of developing the Porsche 911 road car for racing, and in doing so he created eventually what is by far the most successful customer race car that Porsche ever produced: the Porsche 935 which won at the 1979 24 Hours of Le Mans outright, a remarkable feat for a modified 15-year-old road car design. Following this, Singer designed the bodywork of the Porsche 956 and 962 Group C cars which won 7 24 Hours of Le Mans titles  and three Manufacturers’ and two teams’ World Championships between 1982 and 1986 In the 1990s, Singer engineered the Porsche WSC open sports car which claimed two victories in 1996 and 1997. He oversaw the Porsche 911 GT1 project which finally put the 911’s engine into the middle, something that he'd wanted to do since the 935.
