The engine of the 1974 Porsche 911 Carrera RSR Turbo 2.1 was equipped with a KKK turbocharger and generated between 460 and 490 horsepower depending on the boost pressure. This was roughly the same performance as the engines in the three-litre prototypes it competed against, but the latter had aluminium monocoques or tubular structures, while the Porsche had a steel chassis, making it much more heavy. As data, the 1973 Porsche Carrera RSR weighed 930 kilograms and prototypes such as the Matra weighed around 650 kilograms. For this reason it was essential to try to reduce weight.
As there were no size limitations on the tires, wider 17-inch rear tires were fitted, which meant that the magnesium wheels of the 917 could be used. But of course many other aspects were modified in search of a lower weight. The roll cage was made of aluminium, as per regulations. The doors were made of a paper-thin fiberglass composite and weighed 2.25 kilograms each, including the window frame. The engine cover, front hood, and fenders were also made of composite materials. But many other details were worked on, such as the seat rails that were made of titanium, or the rear side windows that were replaced by plastic ones. In the end, the Carrera RSR Turbo weighed in at 825 kilograms, which was an amazing result for a production racing car.
The 1974 season began with a fifth-place finish at Monza for Gijs Van Lennep and Herbert Müller. In the next race, held at SPA, they finished third, followed by a sixth-place finish at the Nürburgring. All were very relevant results considering that the Carrera RSR Turbo was competing against prototypes from Matra, Alfa Romeo and Mirage. The next race, the 24 Hours of Le Mans, was the best result so far, taking an incredible second place at Le Mans, which could have been better if they hadn't run out of fifth gear with several hours of racing to go, and also the Porsche team itself repaired the gearbox (of Porsche origin) to the winning team of the race, the Matra MS670C of Pescarolo and Larrousse. The following races were also successful, with Müller and Van Lennep finishing sixth at the Österreichring and second at Watkins Glen behind a Matra.
Porsche finished the 1974 World Championship for Makes in third place, behind Matra and Gulf Ford. When the introduction of the new Group 5 regulations was delayed until the 1976 season, Porsche's racing program came to a complete halt.
