Zakspeed 841 History
The car was powered by a four-cylinder turbo engine developed by Zakspeed. This was considered the first Formula 1 racing car since the Porsche 804 of 1962, which had been completely developed in Germany.
Erich Zakowski entertained since the 1960s in Niederzissen a Ford representation. From 1968 he took part in motorsport events with Ford vehicles, which had prepared his own company. In the 1970s Zakspeed was a regular participant in the German Racing Championship , which won the team several times. Zakspeed received increasingly factory support during this time. At the beginning of the 1980s, Zakspeed's motorsport program was broad: the team was engaged in modified Ford vehicles in Group 2 and Group 5 . In the late 1970s Zakspeed became a "pioneer Turbo": As of 1978, the team put forward self-developed supercharged four-cylinder engines in racing based on Ford blocks. The over 700-hp Zakspeed racing cars, based on Ford-based production models such as the Capri , were among the most powerful vehicles in their series, and Zakspeed's experience in handling supercharged racing engines grew.
At the beginning of the 1980s, Erich Zakowski hoped to get from Ford the order to develop a turbo engine for Formula 1. Ultimately Ford gave the contract to the British subsidiary Cosworth , which had the engine ready in early 1986. Erich Zakowski then decided in the summer of 1983, on his own responsibility and without financial support from Ford to move up to Formula 1. Zakspeed developed in the following months, a turbo engine to Formula 1 rules and its own chassis, the prototype was ready in the summer of 1984. The Formula 1 debut took place only half a year later in the 1985 season.
Zakspeed was the only team besides Ferrari and Renault to produce the chassis and engine itself. The 841 was the first monoposto engineered by Zakspeed . The development was led by the former Chevron - March - and Maurer -Staff Paul Brown , aerodynamics developed longstanding Zakspeed technician Helmut Barth. At its debut, the car was perceived as befitting of the times.
The chassis had an aluminum core with complementary carbon fiber components. It weighed 26 kg. The wind tunnel tests were carried out at the facilities of the University of Aachen ; Zakspeed claimed that the team spent 600 hours of research in the wind tunnel. The front suspension consisted of double wishbones . The shock absorbers supplied Koni . A special feature of the 841 was the division of the radiator: The water and the oil cooler were in the right side box, while the intercooler was housed in the left side box. The transmission involved Zakspeed from Hewlandbut modified the case.
Zakspeed's engine was a four-cylinder, developed under the leadership of Norbert Kreyer . At times, the Italian engineer Gianni Marelli , who had previously worked at Ferrari and Alfa Romeo , worked for Zakspeed in an advisory capacity. The engine had no connection to Zakspeed's earlier turbo engines, which were based essentially on Ford engines. The cylinder block was made of aluminum. The two overhead camshafts were driven by gears. Kreyer used a turbocharger purchased from KKK ; the intake manifold injection provided puffer fish, Initially, it was a purely mechanical injection; It was only at the Grand Prix of Great Britain in July 1985 that an electronic control system developed by Zakspeed itself was ready for use. The ignition was an in-house development by Zakspeed. The engine weighed 125 kg without turbocharger. Compaction was initially 6.5: 1; during the summer of 1985 it was raised to 7.0: 1.
For the performance of the engine, there are different information. Zakspeed himself speaks retrospectively in a publication from the year 2011 of 700 hp. Zakspeed made numerous detailed modifications. Among other things, the oil tank was increased from 8 to 12 liters, which required an extension of the wheelbase by 80 mm. zakspeed used fuel from Shell ; the tires came from Goodyear .
Zakspeed made two copies of the 841. The first vehicle was ready for use in the summer of 1984, the second only in May 1985. The 841/02 was slightly warp-resistant than the first copy, but nevertheless lighter. The weight was given as 565 kg.
