Porsche 935/77 #41 (08/10/18):
The Porsche 935 was certainly one of the most iconic racing cars of the 70’s. A so-called “silhouette car”, it borrowed it’s looks from Porsche’s 911 (930) Turbo of 1974. Produced from 1976 to 1981, the 935 was one of the most successful cars of the Group 5 era. The chassis was of an unitary steel construction, and the engine was the famous Typ 930/72. At the time, a Group 5 car could have an engine up to 4 l and should weigh only 970 kg. So to keep things light, Porsche opted for turbo-charging. That meant that using the 1.4× turbo equivalency rule, the new engine could only have 2857 cm³. The engineering team then fitted a large KKK turbo hung behind the engine, mated to an intercooler. The resulting flat-6 delivered a massive 580 to 630 hp, depending on the tune.

Though the 935 obtained good results in 1976, by the end of the year Porsche was already working on its replacement. Many details were changed or upgraded, but the big difference would be the engine. One of the main issues with the 930/72 engine was the turbo lag caused by that huge single turbo. To address that Porsche used two smaller KKK turbos instead. With twin-turbocharging the new Typ 930/77 delivered up to 680 hp.

The 935/77 sports the “regular” tail – as the car received upgrades and enhancements, the tail changed a lot.

Kremer Racing had a very straight relationship with Porsche. From the team’s beginning in 1962, the Kremer brothers only raced Porsche cars. So Kremer was the first privateer team to adopt the 935 as their weapon of choice for endurance racing. The team bought this 935/77A #44 (chassis #930-8900012) new in early 1978. The car’s first race was at the 24 Hours of Daytona, in February 1978. Unfortunately it had engine troubles and DNF. For the 24 Heures du Mans of that year, Kremer counted on direct factory support from Stuttgart. They had three cars in the race, one 935 K2 and two 935/77A. Of the three cars, the pilots of #44 were the least experienced, and 1978 was their first race at La Sarthe.

Possibly Porsche’s most successful privateer car.

However, junior team or not, Cord, Busby and Knoop had a smooth race. While #46 abandoned due to engine failure and #45 lost too much time in the pits (and DNC), 935/77A #44 soldiered on. To the point that they finished in sixth overall and first in Group 5. In model terms, though, being from Spark, the car is a winner from the get-go. Rookie pilots notwithstanding the model looks pro, and was a great acquisition for the W-143 Garage.
