NASCAR tested eight cars on the chassis dyno after the race to see if there is a measurable loss in power after a 500-mile race with the recent switch to unleaded fuel.
Cars tested were those of winner #48-Jimmie Johnson, #20-Tony Stewart, #17-Matt Kenseth, #99-Carl Edwards, #42-Juan Pablo Montoya, #2-Kurt Busch, #22-Dave Blaney and #44-Dale Jarrett.

Can’t wait to see the numbers. I’ll bet the 48 put out 20 more
HP than any other engine. Maybe it’s fuel additive!!
