Midget
Car Specifications
|
Combine
an open cockpit and upright seat with a small lightweight chassis,
and then bolt on as much horsepower as you can squeeze into a compact
engine. The result is a pure racing machine built for heart stopping,
wheel-to-wheel action. These cars are at home on both paved and
dirt surfaces.
Midget
racing dates back to the 1930’s, and the basic concept has
always been the same. Place the greatest amount of power on the
smallest frame possible and put on an exciting show. The small size
of these machines, combined with their power-to-weight ratio (2.5
pounds per horsepower), makes them perfect for oval tracks that
are .5 mile and smaller in length. But, turn them loose on a larger
track, and the speeds can reach over 150 mph, making them attractive
for almost any racing facility of 1 mile or less.
USAC
Midgets must weigh a minimum of 900 pounds without the driver and
are limited to a wheelbase of 66 to 76 inches. Typically a midget
engine can produce between 325 and 350 horsepower. For the mechanically
minded, one of the highlights in USAC Midgets is the wide variety
of engine designs. Power emanates from normally aspirated, internal
combustion, four cycle, piston type engines
with a maximum of six cylinders. All engines are fuel injected and
burn straight methanol. From those basic guidelines, some of the
most creative engine builders in racing have placed their mark on
the sport.
Although
the cars are small, the costs associated with midget racing are
not. A basic car ready to race can cost between $40,000 and $60,000
without any extras.

USAC
Midget racing has been a proving ground for some of the nation’s
great racing talent, due in part to the variety of tracks and the
quick reflexes necessary for this type of racing. Former National
Midget Series standouts Jeff Gordon, Tony Stewart, Billy Boat, Ryan
Newman, Jason Leffler and John Andretti have turned a spotlight
on the series as a source of racing talent. Other notable drivers
who have made their way through the USAC Midget ranks include A.
J. Foyt, Mario Andretti, Johnny Rutherford, Parnelli Jones and Mel
Kenyon. |
