CHARLOTTE, N.C. (AP) -- NASCAR is trying to even out the competition in the Nationwide Series.
Stock car racing's governing body is ordering all teams using Toyota motors to squeeze down their horsepower before this weekend's race in Indianapolis.
Toyota has won 14 of 21 races this season in the Nationwide Series, and all but one of them came in Camrys fielded by Joe Gibbs Racing. The exception was JGR driver Kyle Busch's victory at Charlotte in May in a car fielded by Braun Racing.
NASCAR recently sent 10 different motors for testing, and found that David Reutimann's Toyota was the best with an estimated 3 percent horsepower advantage over the competition.
