Following the Nationwide series’ Carfax 250 from Michigan International Raceway, NASCAR put 10 cars on the chassis dyno to check horsepower.
According to SceneDaily, NASCAR checked Roush Fenway Racing’s Fords of Carl Edwards and Greg Biffle; Joe Gibbs Racing’s Toyotas of Tony Stewart and Joey Logano; Braun Racing’s Toyota of Brian Vickers; JR Motorsports’ Chevys of Brad Keselowski and Mark Martin; Richard Childress Racing’s Chevy of Clint Bowyer, Phoenix Racing’s Chevy of Mike Bliss; and Chip Ganassi Racing’s Dodge of Dario Franchitti.
This test came following a Nationwide series rule change in which NASCAR changed the size of the spacer used to restrict airflow in the engines to limit horsepower.
SceneDaily is reporting that Joe Gibbs Racing will be penalized for attempting to manipulate the throttle so that the dyno testing results would not be accurate.
NASCAR spokesman Jim Hunter said:
What they did was not in effect during the race. They didn’t have an illegal part or engine during the race. They tried to do something involving a magnet so that we wouldn’t get a true reading on the dyno.
There will definitely be penalties coming.
For JGR’s part, spokesman Mike Arning said:
The parts and pieces that were on our cars [in the race] adhered to the rulebook. There was nothing out of the ordinary.
