Superchips Dyno Testing: 1983 Porsche 956
Because of our impressive history with road and race cars, we're sometimes contacted with special requests. This 1983 Porsche 956 is the Mass/Bellof car as used at Le Mans, which visited us to use our dyno for a gearbox shakedown and ECU testing. This car uses an older Bosch Motronic ECU with removable chips, which we tested and provided spares for. This video shows a bit about how our Maha LPS3000 dyno can be used as a tool for more than just measuring flat out horsepower. The dyno was configured to run at a constant speed of no more than 120kmh. The car was then cycled through the gears, with throttle applied at the constant speed to ensure the rebuilt gearbox worked as expected. The dyno applies more and more load to ensure the wheel speed never exceeds 120kmh, allowing partial load testing. This also allowed us to swap the ECUs running the car for consistent results. A full power run was not required by the customer.
About Porsche 956
The Porsche 956 was a Group C sports-prototype racing car designed by Norbert Singer and built by Porsche in 1982 for the FIA World Sportscar Championship. It was later upgraded to the 956B in 1984. In 1983, driven by Stefan Bellof, this car established a record that would stand for 35 years, lapping the famed 20.832 km (12.93 mi) Nürburgring Nordschleife in 6:11.13 during qualifying for the 1000 km Sports Car race.
