also power, but several head gasket failures meant that Porsche had some home work to do for 1978. The works 935/77 qualified sixth at the 1977 24 Hours of Le Mans, behind the Renault Alpines and the 936s, but engine troubles ended their race early. As in 1976, a 936 won after the turbo powered sportscars chased each other into troubles. This time, a customer 935 finished third overall. 935/77 The 935/77 body style was used also for winning one race in the small 2.0 litre Div. II of the DRM (predecessor to the DTM), to prove that Porsche could also compete in that class. In Div. I, the customer 935s raced each other, and German TV announced that at the Norisring, it would thus cover only the Div. II race. Porsche engineers were sent to the drawing boards to reduce the capacity of the air-cooled flat-six to 1,425 cc. The power output of the engine was . The weight could be lowered to according to rules in this class. To achieve this, large parts of the chassis were replaced by a tubular aluminium space frame. At the time, Zakspeed-Ford and Schnitzer-BMW were in transition from the naturally aspirated 2.0 L 4-cylinder engine rated at about to 1.4 litre turbocharged engines rated at an excess of . These engines would later move on to Formula One, with the BMW powerplant winning the 1983 F1 Championship, and becoming the strongest F1 engine ever, producing up to in qualifying trim. In the first outing at Norisring in early July 1977, both the new car with Jacky Ickx behind the wheel had problems due to overheating. Skipping the Diepholz airfield round, Porsche sorted the car out for the DRM support race of the 1977 German Grand Prix at the fast Hockenheimring (long version). In changing weather conditions, Jacky Ickx set pole by almost three seconds and won with 50 seconds, setting fastest lap in the process. With its mission accomplished, the Porsche 935/77 2.0 (chassis 935/2-001) was retired to the Porsche Museum. 935 L1 Following the factory effort of the 935/77, Porsche privateer Jan Lundgardh wanted to enter the 935/77 in the Deutsche Rennsport Meisterschaft and World Sportscar Championship, but Porsche was reluctant to provide him with a factory 935/77 chassis. Lundgardh with the help of Porsche engineer Eberhard Braun managed to procure an original engine from the 935/77 project which produced .
