t Buchet was a French pilot, one of the most eye-catching race drivers France ever 
had. He started racing le mans in 1963 with a 356. In 1964 five 904/4s competed at the 
24 Hours and all five finished. The highest placed car the #34 finished seventh overall, 
winning the GT 2.0 class, after completing 4,344km at an average speed of 181kph. 
French pilots Robert Buchet and Guy Ligier drove #34 : Ligier would become famous for 
his own cars later in the Le Mans story.
In 1967 he won the 12 hours of Reims in a Porsche. In 1968 at le mans The Philippe 
Farjon team was one of the privateer teams with the upgraded 907 LH. Their only car 
was 907 LH #67, conducted by Herbert Linge and Robert Buchet. Unfortunately, 907 LH 
#67 had a problem with its starter motor and had to abandon on the 102nd lap.
After a big crash in 1968 R.Buchet decided to start his own team for le mans. 
He managed a Porsche dealership in France and started to let race a 3.0 RSR under his 
team and won the European championship GT cars and race in le mans in 1973-1974-
1975, in the top 10 overall and top 5 in class.

a RSR 3.0 was made in small numbers for racing. For the privateer in the mid1970s who wanted to go sports car racing, and in particular compete successfully at the 
famed 24 Hours of Le Mans, there was really only one viable option, the Porsche RSR. 
Introduced in 1973, the 2.8 RSR was a factory-built racing car based on the 911 chassis. 
These were not converted street cars, but rather purpose built competition models 
designed and built from the ground up for serious racing use.
In 1974 the factory made significant changes to the car including a new 3.0 liter engine, 
wider wheels with center lock hubs and improved aerodynamics. The result was a car 
that would dominate the GT category and challenge for overall wins around the world, 
and the 3.0 RSR would go on to become the most successful Group 4 racing car of its 
time. Its combination of low weight, immense Porsche 917 brakes, impeccable 
handling, and a 330+hp naturally aspirated flat-6 that gave the model a power-to-weight 
ratio that would humble even the most mighty offerings from Italy, England or America.
Compared to the 2.8 litre version used in 1973, the bigger engine featured a larger bore 
and a sturdier aluminium instead of a magnesium crankcase to cope with the additional 
forces. The Type 911/75 flat-6 engine had twin-plug ignition, high-lift camshafts, Bosch 
twin-spark fuel injection, a compression ratio of 10:3.1, dual megaphone exhausts, a 
dry sump oil tank, and the same 5-speed transmission from the RS. Power was 330 bhp 
@ 8000 rpm and torque was 232 ft lbs @ 6,500 rpm. The increase in power was great, 
but for racing the bigger benefit was that these changes substantially improved the 
reliability. Completing the drivetrain was a reinforced clutch and a five-speed gearbox.
Since nobody was using the 917 parts bin, Porsche went to down and took the 917s 
brakes and center-lock wheels, while flared wheel arches, a front airdam, and the now 
iconic “tea-tray” spoiler gave the car a very aggressive posture. As a result the RSR 
appears notably different to the RS thanks to these wide fiberglass wheel arches 
covering 10.5 inch wheels at the front and 14 inch wheels at the back. The rear arches 
include air intakes to help cool those 917 sourced brakes.
Fiberglass was also used in the bumpers, the engine cover, the front trunk lid, and the 
rear “Tea Tray” spoiler. Lightweight Perspex windows replaced the glass in the side 
windows for further weight savings, and the interior was stripped of all but the bare 
essentials – a single seat, pedals, a steering wheel, a shifter, and some gauges. By 
further reduce the weight from the already lightweight Carrera RS 2.7, while 
simultaneously increasing power without compromising reliability, the team was able to 
tip the scales at around 900 kg dry. With 330hp on tap, this lightweight Porsche 911 
Carrera RSR 3.0 was capable of a top speed of 179 mph and awesome acceleration.
