Audis Receive Air Restrictor Adjustment Heading Into SPEED GT Finale
7-Oct-2004- TOPEKA, Kan. - SCCA Pro Racing Ltd. announced today a restrictor size change for the SPEED World Challenge GT class Audi RS 6, effective immediately
Stated in Tech Bulletin #13, the Audi RS 6 will go from a 49.4 percent restrictor prior to each turbocharger to a 41.2 percent (34.5mm) air restrictor.
“Prior to Road Atlanta, we made a substantial adjustment to the Audis, going from no restrictor to the 49.4 percent air restrictor,” SCCA Pro Racing Vice President and General Manager Mitch Wright said. “We needed to do this because, with every previous negative adjustment, the cars continued to get faster and faster. The last change was able to give us a baseline, as well as realistic power data to work with. This change will give back a portion of the power that was lost between Rounds Eight and Nine, and is designed to ensure a good, close race at the front of the field.”
The SCCA Pro Racing SPEED World Challenge GT and Touring Car Championships will be decided Sunday, Oct. 17 at Mazda Raceway Laguna Seca. Both the SPEED GT Drivers’ and Manufacturers’ Championships are up for grabs, and the drama will unfold live on SPEED Channel at (Eastern), locally.
The SCCA SPEED Touring Car Drivers’ Championship will be decided earlier in the day, airing at (Eastern), locally.
