1973 Porsche 911RSR 2.8L By Taylor And Crawley

Porsche developed the 1973 911 RSR as a pure racing evolution of the 2.7 RS Carrera only 49 were built in the Factory Racing Department after development of the R-numbered experimental pre-series. Above and beyond the production RSRs Porsche produced the highly developed works Martini liveried cars in Europe and in America the Brumos cars for Peter Gregg.

This included larger diameter shock towers to allow the fitment of the new titanium coil-over racing dampers and give the chassis more strength. Body panels including the roof and doors were made from a thinner gauge steel and a more powerful 3.0 litre engine became available during the season.

The authenticity of the car been confirmed by several Porsche experts including Jürgen Barth, it has a current F.I.A. passport and has run in major historic racing events all over Europe for the past few years. It would be welcome in the CER championship, Tour Auto and the Le Mans Classic. 2.8 RSR 911 360 0727 arrived in the US in April 1973 for delivery to the Jacksonville, Florida based Brumos team to be driven by Peter Gregg. It had been specially built by the Porsche factory for Brumos to win both the IMSA and Trans-Am series which were extremely popular both with the racers and the fans. Porsche had realised that there was huge marketing potential there and did whatever was needed for Brumos and Gregg to go home with the trophies.

The Porsche Racing Department built 2.8 RSR chassis number 911 360 0727 to the same specification as the R-Series and Martini Works RSRs giving a substantially stiffer chassis, less weight and a more powerful 3.0 litre engine with mechanical injection and slide valve throttle bodies. The results speak for themselves. Peter Gregg and Brumos won both the IMSA and the Trans-Am series in 1973 with #0727. Peter Gregg and Hurley Haywood were the class of the field but the serious advantage they had with the uniquely prepared Brumos RSR was paramount. In thanks for the great results achieved by Peter Gregg Porsche sold him RSR 911 360 0727 at the end of the season for just one Dollar.
