Tommy Bryant Sprint Car Fuel

Listen as Tommy Bryant explains the fuel set up in a sprint car before and during a race. Typically, they are powered by methanol that is naturally aspirated and mechanically injected. The fuel set up is crucial and quantity is based off of weight and track variables. For a slick track, you want more fuel than you will need in the car for more control while racing. On a dry track, you want as little fuel as possible because you want the car’s rear to be light. Fuel quantities also vary based off of track size, For instance, a longer track requires more fuel.

Sprint cars are high-powered race cars designed primarily for the purpose of running on short oval or circular dirt or paved tracks. Sprint car racing is popular primarily in the United States of America and Canada, as well as Australia, New Zealand, and South Africa. Sprint cars also have a wing on the top of them which helps with the aerodynamics of the car when turning around the track. Wings also affect safety. Added downforce lessens the likelihood of going airborne. When cars do go airborne, the wings frequently break off or absorbing some of the impacts of the flip, lessening the impact on the driver. The wings also provide an amount of protection for the driver in case of an accident and are sometimes referred to as “aluminum courage.” The safety record of sprint car racing in recent years has been greatly improved by the use of roll cages, and especially on dirt tracks, wings, to protect the drivers.
