World of Outlaws

World of Outlaws Sprint Car Series

The body sanctions a national tour of high power to weight, custom fabricated sprint cars called the World of Outlaws. The race cars feature large adjustable wings on the top and large rear tires that transfer their power to the dirt tracks they race on. The series travels primarily the United States, but has sanctioned races in Canada, Mexico and Australia.

The series was founded in 1978 by Ted Johnson, a former midget racer from Madison, Wisconsin. At the time sprint car racing in the United States lacked a true national series. Johnson organized the World of Outlaws sanctioning body and established a national schedule, a set of rules and a points system to crown a champion of his series. Today, the 2016 season will feature 91 races at 54 different tracks in 25 states and one Canadian province. Select events are broadcast on Dirt Vision, an online subscription based streaming service, while other select races are broadcast nationally on the CBS Sports Network.

Sprint car specifications

A World of Outlaws Sprint Car is a purpose-built open-wheel race car that must weigh at least 1,400 pounds with the driver in the car. The 410-cubic inch engine is fueled by VP Racing Fuels methanol. The cars produce over 900 horsepower and transfer it to the ground through Continental Tire, the series' specification tire . The World of Outlaws and Continental Tire will designate the legal compound types, as each circuit differs in which type of compound works for a circuit. The series' cars have a large top wing with sideboards that face opposite direction to help produce a great amount of downforce to plant the car on the track and help the car turn and maximize grip, both in the corners and on the straightaways. All racecars must weigh a minimum of 1400 pounds with a driver fully prepared to compete in the car throughout an entire event. The cars also have smaller nose wings.

Sprint cars use quick change rear ends. This allows the teams to quickly change the gear ratio for different size tracks. Most cars use a torsion bar suspension system. Different size bars either soften or stiffen the suspension. Torsion bars, and specialty shock absorbers are the key ingredients in the handling of sprint cars. That coupled with the wings, tire stagger, light weight, and enormous horsepower make these cars one of the fastest race cars in the world using a horsepower-to-weight ratio. The monstrous power-to-weight ratios of Sprint Cars can exceed that of Formula 1 cars.

Sprint Cars have a very distinct stance since they have two very different sized rear tires. The right rear tire on a sprint car is 105 inches in circumference. In contrast, the left rear tire is only between 90 and 98 inches in circumference, depending on the track size and conditions. The difference in the tire sizes is called stagger and the more stagger the car has, the easier it turns into the corner, but at the expense of straight line speed.

Sprint Cars do not have starters in them, so push trucks are used to fire the engines. Sprint Cars only have an in/out direct drive, no reverse gear and no clutch.
