This form of motorsport has to be experienced to be believed. Exotic, custom-built machines with absolutely no limitations compete to determine who has the best combination of horsepower, chassis setup and pulling skill in several different classes. From four supercharged engines powered, ground shaking, 10,000 horsepower tractors to jet turbine powered, flame belching semi-trucks, this series is all about America’s favorite homegrown passion, HORSEPOWER.
