Test bench

After the accurate testing of the individual components and the following assembly, the engine approaches the cusp of decision. Here, the wheel of design, manufacturing and assembly turns full circle On the test benches, the components or the entire project have to demonstrate once and for all if they meet the high demands and are worth to represent the name of Spiess out there in the world.

Make-or-break!

Spiess uses five test benches, four of them being engine test benches and one a component test bench. Together, they cover the most different testing options, from air mass flow rate and pressure surveys to external weather determination and media supply. Every test bench is equipped with a Blow-By-Meter. In addition, there is an 'Indymaster AVL' indicating system available for the individual use at the respective test bench.

The test-bench results are permanently surveyed and thanks to the close cooperation of the different departments, it is possible to immediately respond to any potential detraction.

The dynamic test bench represents one of the most realistic testing options. Gear changes, brake points and throttle valve positions can be simulated appropriate to the real racing conditions. The entire engine has to cope with realistic driving situations and different environmental impacts. For the simulation of numerous racetracks, the respective circuit data can be adopted straight out of the car - or exactly according to customer specific driving cycles and parameters. Details »
