1976 Porsche 934 "Turbo RSR"

6 times Le Mans in period, matching nos engine
Model history:

Using the 930 Turbo as a basis, Porsche built the 934 for Group 4 GT racing. It replaced the outgoing Carrera RSR.

Porsche built the 934 from a standard 930 body shell and production rear spoiler, but almost nothing else was left alone. The suspension was converted to solid mounts and nylon bushings with adjustable anti-roll bars. New brakes from the 917 were fitted along with stronger hubs and BBS centre-lock wheels which at 16 inches, were larger than the outgoing the RSR and required more drastic wheel arches. Inside the car was stripped and included an aluminium roll-cage as well as new gauges for fuel and turbo boost levels. A 120 litre fuel tank filled the front trunk along with a oil tank and battery. The oil tank fed a front mounted oil cooler which was fed from a huge cut-out in the spoiler. Beside these were ducts that led to the rear intercoolers. This system added nearly 45 lbs to the car, but was necessary since an air-to-air intercooler could not fit under the standard engine hood that was mandated by the regulations. Porsche took the standard 930/75 engine and fitted new pistons while the block, crankshaft and connecting rods were all production parts. Furthermore the standard ignition and mechanical injection system had to be used. With a large KKK turbocharger, around 485 bhp was possible at 1.4 bar of boost. 
The first 934 prototypes appeared in September of 1975 and it was instantly faster than the outgoing Group 5 Carrera RSR 3.0. This meant almost every team upgraded to the 934 including Kremer and Gelo. As a result the car was very successful in the European GT Championship that was won by Toine Hezemans in the Gelo car. The same could be said about the German GT Championship that effectively became a Porsche-only affair.
Later in production Porsche released a 934½ specification, which included a larger rear wing and updated 930/73 engine that could produce 600 bhp. These were primarily raced in Group 5 and many were used in America for Trans Am duty under the Vasek Polak banner. They dominated the 1976 season with George Folmer behind the wheel and in 1977 Peter Gregg won the championship. By 1977 the 934 was finally accepted by IMSA and many of those cars were updated to Group 5 spec. At Le Mans, the 934 was a regular fixture and competed against the Ferrari 512 BB LM. They took class honours in 1977, 1979 and 1981.
A total of just 41 934 cars were built; Porsche issued a small series of exactly 30 vehicles for the 1976 season (vehicle identification numbers: 930 670 0151 to 930 670 0180). Another factory-manufactured vehicle (VIN: 930 670 0540) followed later. The model was appreciated so much in the USA that Porsche manufactured another small series with 10 vehicles for 1977 (VIN: 930 670 0951 to 930 670 0960). Today, these vehicles are identified as 934 1/2 type.
Thus, a only total of 41 vehicles have been manufactured of the 934-type.

Specific history of this car:

930 670 0177 was delivered to the French Porsche importer Sonauto after having been ordered by Henri Cachia, he purchased it to take part in the 24H of Le Mans.

It was to be the first of six starts on the mythical straight of Le Mans, amazingly this car was never upgraded to 935 spec, something that happened to most 934s back in the days.  In 1981 the car even won its class (Group 4 - GT) finishing 17th over all!

Today the car is represented in the striking JMS racing team “Xray” livery that it wore during the 1977 24H of Le Mans event. The graphic design was sponsored and executed by 3M who showed off their skills and how the cut vinyl could create fabulous racing liveries without painting the car.

The ownership trail and the Le Mans entries of 930 670 0177 are fully documented with original weighing documents from the Le Mans archives, copies of the owners French road registration titles, customs documents and bills of sale.

The engine fitted inside the car is the original matching numbers engine * 676 2027 * which was recently completely overhauled and purchased in Portugal and it's now again reunited with 930 670 0177.

With its 1977 livery back on the car, 930 670 0177 was displayed at the 2016 Le Mans classic event in the concourse d’ellegance and it took home another class win.

Today 930 670 0177 is ready to be exhibited at the worlds most prestigious concourse and vintage racing events. The car is mechanically perfect and ready to be enjoyed at events like Le Mans Classic where due to its historical importance it will be accepted without any problem.

With only 31 vehicles of this type of pure bred racing Porsche built it’s a very rare opportunity to be able to purchase one, let alone one in this condition with such impressive racing pedigree.

6 times Le Mans with one class win.

Finding a car like this that has never been modified into a Group5 935 is also very rare and only a small percentage of the 31 cars have survived in this way, not having ever been majorly damaged is also a rare feat for a race car like this. Add on top the matching numbers engine and the possibility to have both engines the “blank case” race engine in the car to have fun with and the original factory fitted one on the side. It’s a unique package.

A great investment and one that will surely keep rising in value, as these 934s are still surprisingly great value for money compared to other Porsches that have sometimes been built in much greater numbers.
