Thanks to media outlets like YouTube and Autoblog, a good lap time in on the Nurburgring will get you plenty of positive press. The grueling track has become the yardstick by which any performance vehicle is measured, and if you can post a record time, people want to know about it. The engineering geniuses at Porsche have designed a special moving dyno to test g-loads in a virtual 'Ring. The system was used to test the upgraded dry sump oil system for the new 3.6- and 3.8-liter boxer engines powering the 2009 911 Carrera and Carrera S. The dry sump system now has a variable-flow pressure pump that needed to be tested extensively at the 'Ring, but the new system can perform the same task whenever engineers want, and at a fraction of the cost.
Engineers were able to get a near perfect reproduction of a lap on the 'Ring by recording the g-force and engine load during a live lap of the Nordschleife, and then feeding the data into the contorting contraption. Hit the jump to view video of the moving dyno in action. It's pretty radical, and it gives you a better idea of how crazy the 'Ring really is.
