Sprint Car Specifications

With engines producing upwards of 800 horsepower, these 1200 pound rocket ships combine the thrill of raw power with the heart stopping action of non-wing sprint car racing. Dirt rooster tails, wheel stands and three wide racing are the norm when these bad boys come to town. Sprint cars also run on paved tracks and any driver with aspirations of a championship must be able to negotiate both dirt and pavement.
"I think the most challenging racing for a driver is Sprint Car racing on short dirt tracks. When you get a powerful sprinter on a short dirt course you've really got your hands full".
-- Two-time USAC National Sprint CarChampion, Parnelli Jones

"Sprint Car racing is one of the most exciting forms of racing to watch in the world"
.-- Three-time Indianapolis 500 Champion Johnny Rutherford

Sprint cars are powered by 410 cu. in. V-8 engines with aluminum blocks and cylinder heads specially prepared for racing. USAC Western States sprint cars have a maximum of 360 cu. in. These engines use fuel injection and methanol for fuel. Sprint car races are normally held on 5/8 mile and smaller tracks; however, they sometimes make appearances at the 1-mile ovals. Some of the highlights on the USAC Sprint Car schedule are the "Little 500" at Anderson Speedway, the "Tony Hulman Classic" at Terre Haute, "USAC's Indiana Sprint Week", and the "4 Crown Nationals" at Eldora Speedway in Ohio.
