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.
