When factory development stops, tuner development begins. The best known iteration came from Kremer Racing of Cologne, Germany. These cars are identifiable by their unique body configuration as well as a potent, twin-turbocharged, 3.2 liter flat six-cylinder motor producing upwards of 740 horsepower.
Chassis #000 00013 shown has a race history beginning at the 1980 24 Hours of LeMans and ending at Sebring in 1985. The car has had various sponsors such as Jagermeister and Coca-Cola. It has been driven by the likes of Bob Wolleck, Bob Akin and Craig Siebert.
This car has an illustrious European and American racing history, beginning at the 1980 24 Hours of LeMans and ending at Sebring in 1985. It has been driven by the likes of 2007 Amelia Honoree Derek Bell, Bob Wolleck, Bob Akin and Craig Sebert. The 'K3' (this denoted that it was the third variation of the basic 935) was constructed by the Kremer brothers using a factory Porsche tub. Thirteen K3s were constructed by Kremer. The most important differences from other 935s include a 3.2-liter engine, air-to-air intercooler system, lowered chassis, high down-force composite body design, stiffened and extended roll cage, and larger KKK turbos. The Kremer Porsche compression ratio of 7.2:1 and 1.7 bar boost developed 800 hp at 8000 RPM. Even with the boost turned down to 1.4 bar, the engine developed 740 horsepower at 7800 RPM. The 935 K3 was capable of speeds over 200 mph.

It was sold to John Fitzpatrick Racing at the end of the 1980 season and was later sold to Preston Henn. Alegra Motorsports acquired it from the Preston Henn Collection in 2010.
The Porsche 935 K3 (Kremer) was the third variation of the legendary 935. It was created by the Kremer brothers using a factory tub and fitted with a 3.2-liter engine. Large KKK turbochargers were adapted along with an air-to-air intercooler system bringing horsepower to around 800 with 1.7 bar boost. With bar boost turned down to 1.4, a still very impressive 740 horsepower was created. Other differences between the 13 K3 models and the factory 935's were the lowered chassis and high down force carbon fiber Kevlar composite body design. The interior was given a stiffened and extended roll cage in order to handle the extra horsepower created from the finely tuned engine.

In 1976, Porsche introduced a racing version of the Porsche 930/911 Turbo which they dubbed, the 935. It was designed for FIA-Group 5 competition and was constructed in similar fashion to the Porsche 934, which was used in Group 4 competition.
The works team, with sponsorship by Martini, entered the 935 in the FIA World Championship for Makes with team drivers, Jacky Ickx and Jochen Mass in one car and Rolf Stommelen and Manfred Schurti in another car. The Porsche 935 was an evolutionary process, as its original nose was later replaced with more aerodynamic versions better suited to high speed competition. The bodywork changed and a large wing was added to the rear of the vehicle. The rear fenders were expanded and the car was given a wider axle. The Porsche 935 won all of the major endurance races that included LeMans, Nurburgring, Daytona, Sebring, and Watkins Glen.
Group 4 competition was created for production-based GT cars and the Group 5 was for race cars based on production models. For the 1976 season, the FIA declared that the World Champion of Makes would be won from the Group 5 class, which Porsche won with their 935.
For the 1977 season, the Porsche 935's were sold to privateer teams, such as Georg Loos and Kremer Racing. The single turbo was replaced by two KKK units and the body was again changed. The privateers were using the older cars while the factory raced with the newer machines. This left the privateers unhappy, but since the Porsche 935/77 machines were not as reliable, they could be beaten.
For 1978, the famous 'Moby Dick' styling of the Porsche 935 appeared. The Porsche 935/78 had a long tail, and a frontal area that had been lowered by 10cm. The car had been optimized for low drag and its appearance earned it the nickname, Moby Dick. Powering these cars were a 3.2-liter, water-cooled, four-valve cylinder head engine capable of generating 895 horsepower. The cars reached speeds of 360 km/h at LeMans and were capable of passing the prototype cars such as the Renault and their own Porsche 936.
Throughout the seasons, the FIA, SCCA, IMSA, and CSI continued to modify the rules, which had the teams struggling to maintain a compliant group of cars. The 935, over the years, came in many different configurations powered by a wide variety of engines that included a 2.0-, 2.2-, 3.0-, and 3.2-liter size.
Factory development of the 935 slowed and eventually stopped, and tuner development continued where they left off. The most famous iteration came from Kremer Racing of Cologne, Germany. They were powered by twin-turbocharged 3.2-liter six-cylinder engine capable of producing 740 horsepower.
In 1982, the FIA discontinued Group 5 competition. The 935 continued its racing career in the IMSA GTP category. They continued to race until 1986, though their racing career had ended in 1984. Privateers entered the car in 1985 and for two races in 1986.
From 1976 through 1984, the Porsche 935 won over 150 races which includes over twenty class victories. The 935 was the overall victor at the 24 Hours of LeMans, the 12 Hours of Sebring, and the 24 Hours of Daytona.

| THE UNDERDOG UPSET CHARLES DRESSING'S RETELLING OF SEBRING'S 1983 RACE | |
 | Americans love underdogs but hate losers. And we really love upsets because they turn reality inside out and generally make the mighty look weak. So when anyone demands a prediction, I try to hide because I always remember some races that didn't quite go the way the experts reckoned: the 1954 Sebring 12 Hours, 1955 Monaco Grand Prix, the start of the 1958 Race of Two Worlds at Monza (not the whole race, but the start sure was a great moment for sports car types). And then … there was the...[Read more...] |
