Aerodynamics: As applied to racing, the study of airflow and
the forces of resistance and pressure that result from the flow of air over,
under, and around a moving car.
Banking: The sloping of a racetrack, particularly at a curve
or corner, from the apron to the outside wall. Degree of banking refers to the
height of a track’s slope at its outside edge.
Chute: A racetrack straightaway
Drafting: The practice of two or more cars, while racing, to
run nose-to-tail, almost touching. The lead car, by displacing the air in front
of it, creates a vacuum between its rear end and the nose of the following car,
actually pulling the second car along with it.
Esses: Slang term used for a series of acute left- and
right-hand turns on a road course, one turn immediately following another.
Fuel cell: A holding tank for a race car’s supply of
gasoline. Consists of a metal box that contains a flexible, tear-resistant
bladder and foam baffling. A product of aerospace technology, it’s designed to
eliminate or minimize fuel spillage.
Groove: Slang term for the best route around the racetrack;
the most efficient or quickest way around the track for a particular driver.
The “high groove” takes a car closer to the outside wall for most of a lap,
while the "low groove" takes a car closer to the apron than the
outside wall. Road racers use the term “line." Drivers search for a fast
groove, and that has been known to change depending on track and weather
conditions.
Horsepower: A measurement of mechanical or engine power.
Measured in the amount of power it takes to move 33,000 pounds one foot in a
minute.
Interval: The time-distance between two cars. Referred to
roughly in car lengths, or precisely in seconds.
Jet: When air is sent at a high velocity through the
carburetor, jets direct the fuel into the airstream. Jets are made slightly
larger to make a richer mixture or slightly smaller to make a more lean
mixture, depending on track and weather conditions.
Loose: Also known as “oversteer.” When the rear tires of the
car have trouble sticking in the corners. This causes the car to “fishtail” as
the rear end swings outward during turns. A minor amount of this effect can be
desirable on certain tracks.
Magnaflux: Short for “magnetic particle inspection.” A
procedure for checking all ferrous (steel) parts (suspension pieces, connecting
rods, cylinder heads, etc.) for cracks and other defect utilizing a solution of
metal particles and fluorescent dye and a black light. Surface cracks will
appear as red lines.
Neutral: A term drivers use when referring to how their car
is handling. When a car is neither loose nor pushing (tight).
Oil pump: This device pumps oil to lubricate all moving
engine parts.
Pit road: The area where pit crews service the cars.
Generally located along the front straightaway, but because of space
limitations, some racetracks sport pit roads on both the front and back
straightaways.
Ride height: The distance between the car’s frame rails and
the ground.
Slingshot: A maneuver in which a car following the leader in
a draft suddenly steers around it, breaking the vacuum; this provides an extra
burst of speed that allows the second car to take the lead. See Drafting.
Trading paint: Slang term used to describe aggressive
driving involving a lot of bumping and rubbing.
