The 908 model reference applies to racing prototypes entered by Porsche in the 3-liter class. Its production ended in 1971. To support its successors with commercial models, Porsche re-engineered the high-end of their 911 and created in 1973 the 911 Carrera RS and RSR with 2.8-liter engine. In 1974 they push the capacity of the RSR to 3 liters.
The Porsche Turbo is also developed in 1974 with a 2.1-liter engine and a compression ratio of 1.4 which remain compatible with the regulations of the 3-liter class. Four Porsche 911 Carrera RSR 2.1 Turbo are built and two of them are entered in the 24 hours of Le Mans.
To everyone's surprise one of these two experimental Porsche Turbo driven by Müller and Van Lennep proved to be the only car capable to compete with the Matra of Pescarolo and Larrousse and finished the race in second position overall. The best Carrera RSR 3.0 non-turbo was seventh.
The same Porsche Turbo driven by the same works team achieves a similar feat in the following month at the 6 hours of Watkins Glen. Sold by Porsche after the end of that season, it is little used thereafter. Well preserved in an excellent original condition, it is estimated $ 6M for sale by Gooding at Amelia Island on March 9, lot 22. Here is the link to the press release.
The achievement of this 911 2.1 Turbo encourages Porsche to develop their turbocharged range. From 1975 the Porsche 911 Turbo with 3-liter engine also known as Porsche 930 becomes one of the best commercial successes of the great 911 range. In 1976 their 934 and 935 evolutions are approved for Groups 4 and 5 of the FIA.
