1975 Porsche 911 Carrera RSR Replica
VIN No. 9115201219
A track-only version called RSR 3.0 was created to compete in the FIA Group 4 category. It was a development of the RSR 2.8. Its racing career began in 1973. In order to make the new car compliant with homologation rules, its aerodynamics had to be changed. Rear spoiler from the road-going version, commonly referred to as the 'ducktail', was replaced with a tail fin. On top of that, wheel arches have been flared.
Carrera RSR 3.0 was powered by a 3-litre, air-cooled, horizontally opposed engine. It was equipped with a mechanical fuel injection by Bosch, which enabled it to produce 330 BHP at 8000 rpm. Compression ratio was also increased to 10:3.1. Twin-exhaust was borrowed from the RSR 2.8. Coil springs in the suspension were made of either steel or titanium. They were hidden behind a hefty set of wheels, 15-inch at the front and 14-inch at the rear. Power was transferred to the rear axle via a five-speed manual gearbox, which was connected to the engine with a clutch made by Sachs. Several body panels and interior parts were made of aluminium for weight reduction. As a result, the RSR 3.0 weighed just 900 kg. Adding power and getting rid of unnecessary weight made it hugely fast. Top speed was 270 km/h, whereas 0-100 km/h was dealt with in just 5 seconds.
Porsche sold the RSR 3.0 to many private racing teams (i. a. Kremer or Gelo), which were successful in a number of prestigious racing series. Overall, just 110 examples of the RSR 3.0 were made. In the meantime, Porsche created a prototype of a turbocharged RSR 2.1 model, which finished second in the 1974 24 Hours of Le Mans.
