By swinging the engine around, the test rig simulates the g-forces involved with a “stroll” around the Ring.
Porsche has created a engine dyno test rig which simulates driving the Nürburgring Nordschleife without a car. By swinging the engine around, the test rig simulates the g-forces involved with a “stroll” around the Ring. As a result, engineers can evaluate all engines systems as well as the new dry-sump oil system, which utilizes a variable-flow pressure pump, under the rigorous driving conditions of the Ring without actually going to the Ring. The big advantages of such a setup include the associated cost and time savings with track time and logistic requirements - not to mention dependence on favorable weather conditions.
In a trip to Porsche's technical center at Weissach during the introduction of the 2009 Porsche 911 Carrera. the folks at InsideLine.com were good enough to capture the rig in action. Check out the
the G-meter and the Nürburgring Nordschleife map locator at the bottom of the screen.
