There are things that you will never forget once you see them. In my case, this is the rear view of the Jaegermeister Porsche 935 K3 suddenly appearing in front of me on a circuit. The orange bats running away at a blazing speed while making a swooshing sound surprised me. It has been 30 years since the great success of Group 5 racing cars in the late 70's. The impact of that time is still unforgettable.
Stuttgart annual classic car festival “Retro Classic”. In 2013, Cromer Racing's Porsche 935 K3 was displayed in its original design of the orange-shining Jaegermeister, which attracted the attention of the public.
The story of Kremmer's success begins in 1962 when Cologne-born Irvin and Manfred Klemmer step into the world of motorsport. For them they launched Kremer Racing, but since then they have specialized Porsche.
Manfred is in charge of maintenance and vehicle development, and Irvin runs the circuit and repeats the test. This division of work worked well, slipping the 911S into sixth place overall at Le Mans in 1970, and winning the Porsche Cup the following year. Since then, the gears of the Kramer Racing Team have begun to spin at full throttle, increasing their reputation in the racing world. The 70's was a time when their ideas and ideas for racing flourished at a stretch, and immediately incorporated them into the 934 Turbo that had just emerged.
K1 was the first 935 to launch ideas built for FIA Group 5 regulations. K1 is immediately replaced by K2. The K2 was a racing car that completely sublimated the ideas of the Klemmer brothers. In 1979, the Clemer Racing Team mastered Porsche polishing techniques. Klemmer Racing, which was just one of Cologne's garages, has already become a charismatic presence in race car making, and the third K3 of the 935 was fast enough to be recognized as the strongest 935 in history.
K3 was surprised to win 11 of the 12 races in the first season, but everyone was stunned to have suddenly won Le Mans in his debut race. What's in this car that no other car has? It was a topic of interest among Porsche engineers. Even the works' racing cars, which the professionals have pursued to the utmost, look hazy in front of Clemer Porsche.
Basically, the body of the K3 is the same as the production 935 turbo, which uses lightweight, aerodynamic Kevlar bodywork produced by Design Plastics. The 935 K3 can be said to have put all its efforts into maximizing downforce. Therefore, the front and rear fender parts, and the rear window area described later, are completely different. Inside the body skin, the mounting points of the roll cage and the front and rear suspensions are fastened with extension rods, which play one or two roles in improving the rigidity of the body. A single triangular strut bar extends to the right and left near the center of the vehicle body to increase the torsional rigidity of the vehicle body.
In other words, since the body panel is structured so as not to receive any stress, many of the body panels can be easily removed, and in fact, even if the mechanic needs to maintain it immediately after driving, If you remove it, you will be released from heat hell. The greatest knowledge that Klemmer gained from experience is the cooling method of the intercooler. The original 935 was equipped with a water-cooled heat exchanger, but had the disadvantage that the engine power was visibly reduced as the coolant temperature increased. Manfred Klemmer and his development team have narrowed their wisdom on how to keep the engine running at peak performance until the end of the race. The answer was clever and simple.
