(Sim)racing terminology

Discussion in 'Other Racing Games' started by trobwal, Feb 4, 2015.

  1. If you're gonna sim-race, then you better know the lingo. Here are definitions of both legitimate words, slang words and phrases commonly used in sim-racing. Don't wonder about the meaning of these words ever again. tnx to www.rimcotech.com

    A-J

    A

    AERO
    Commonly used abbreviation when referring to the all-important science of aerodynamics.
    AERO PUSH
    When following another vehicle closely, the airflow off the lead vehicle does not travel across the following one(s) in a normal manner. Therefore, down-force on the front of the trailing vehicle(s) is decreased and it does not turn in the corners as well, resulting in an "aero push." This condition is more apparent on the exit of the turns.
    AERODYNAMICS
    The science of understanding different forces acting on a moving element in gasses such as air. The application of this study to racing is credited with much of the sport's recent progress as teams learn more about drag, air turbulence, and down-force.
    ADDING SPOILER
    This is a term used to describe the changing of the direction of a spoiler or wing on a race car. Usually adjusting the angle of the spoiler creates down-force and gives more grip on the race track.
    AIR DAM
    A metal strip that hangs beneath the front grill of a stock car, often just inches from the ground. The air dam helps provide aerodynamic down-force at the front of the car.
    AIR PRESSURE
    With the advent of radial tires with stiffer sidewalls, changing air pressure in the tires is used as another setup tool that is akin to adjusting spring rates in the vehicle's suspension. An increase in air pressure raises the "spring rate" in the tire itself and changes the vehicle's handling characteristics. If his race vehicle was "tight" coming off a corner, a driver might request a slight air pressure increase in the right rear tire to "loosen it up."
    ANGLE OF ATTACK
    The angle of an Indy car style wing. The angle is varied by track to produce optimal down-force and minimize drag.
    ANTI-ROLL BAR
    A lateral torsion bar used to resist or counteract the swaying force of the car body through the turns.
    APEX
    The geometric inside center point of a corner. In racing, a driver will often use a "late apex," turning into the corner a little later than normal in order to straighten out the last part of the corner. This allows the driver to accelerate earlier and harder, gaining maximum speed down the next straight.
    APRON
    The paved portion of a racetrack that separates the racing surface from the infield. It is usually flat in comparison to the racing surface.

    B

    BACK MARKER
    A car running off the pace near the rear of the field.
    BACK OFF
    To slow down; often said of a driver who is attempting to pass and realizes he can't make it, so he backs off to try again later.
    BACK OUT
    When a driver takes his foot off the gas pedal (all the way or part way), he "backs out" or "lifts off."
    BALANCE
    When a car doesn't tend to over-steer or under-steer, but goes around the racetrack as if its on rails, it's said to be in balance. See Neutral
    BANKING
    On oval tracks, the corners are often tilted inward to provide faster speeds. On some road courses, certain turns may actually be banked outward, a very difficult type of corner known as "off-camber."
    BANKED TURN
    A turn that's inclined so the outside area is higher than the inside area.
    BEND
    A shallow turn.
    BERM
    Raised sections of asphalt or cement which runs along the inside and/or outside of a turn, usually painted colors to offset it from the track. Primarily used at apexes and track-out points as a driver’s aid.
    BLACK FLAG
    The signal for a driver to come into the pits, usually to allow officials to inspect it to determine whether it can run safely after an accident. It may also mean that officials have already decided the car is to slow or too dangerous to continue running, as when it has a serious oil leak that makes the track slippery.
    BLUE FLAG
    This flag is displayed by corner workers around the track to signal to a driver that a faster car is either approaching (steady flag) or attempting a pass (waved flag). The driver being flagged has no obligation to do anything other than be alert, maintain the racing line and avoid intentionally obstructing the faster car.
    BINDERS
    Brakes. Used in the expression "jumped on the binders."
    BITE
    The amount of traction that a race car has at the rear wheels. Adjustments can be made to the car that puts more "bite" into the rear tires by adding weight or wedge to the car.
    BLIND TURN
    A turn in which the driver cannot see the apex or track-out until it is reached. Sometimes due to elevation changes, but can also be due to visual obstructions such as Armco, tire walls, or other barriers.
    BLIP THE THROTTLE
    To tap the accelerator pedal when downshifting in order to match the revolutions of the engine to the revolutions of the transmission to keep the drive wheels rotating smoothly.
    BLISTER
    Excessive heat can make a tire literally blister and shed rubber. Drivers can detect the problem by the resulting vibrations and risk more serious damage if they choose not to pit.
    BLOCKING
    Racing term for changing position on the track to prevent drivers behind from passing. Blocking is accepted if a car is defending position in the running order but considered unsportsmanlike if lapped cars hold up more competitive teams.
    BLOW UP
    Irreparable engine failure which ends a racer’s day.
    BLOWER
    A slang term for Supercharger.
    BLOWN ENGINE
    1. An engine that has completely failed.
    2. Slang term for a supercharged engine.
    BOBBLE
    A miscue by a driver.
    BOOST
    The amount of pressure generated by a turbocharger or supercharger as it forces the air/fuel mixture into a forced induction engine.
    BOW TIE
    Nickname attributed to Chevrolet based on the likeness of its logo.
    BRAIN FADE
    A lack of focus that can lead to making a mistake during a race.
    BRAKE BIAS
    In most cars, including street cars, pressing on the brake pedal applies a little more force to the front brakes than the rear. This is designed to take advantage of the fact that under braking, weight transfers to the front of the car. With lots of weight on the front tires, the brakes can be applied very hard without completely stopping the wheels from rotating ("locking the wheels"). At the same time, the rear of the car tends to get lighter, so the rear brakes must be engaged less than the fronts to avoid locking the rear wheels and possibly losing control. In a race car, brake bias is adjustable by the driver to compensate for changing conditions, such as on a wet track where there is less weight transfer to the front of the car under braking, or to adjust for a changing center of gravity as fuel is burned off.
    BRAKE FADE
    Loss of braking effectiveness, usually caused by overheating. Brakes transform motion into heat. The heat in the rotors of a car can reach 5,000 degrees F. When the fluid in the brake system exceeds its boiling point due to hard use, bubbles can form in the brake lines and calipers. Since these bubbles can be squeezed smaller by pressure from the brake pedal, the pedal tends to "go soft" and may even go to the floorboard without the brakes working properly.
    BRICKYARD
    Nickname given to the legendary Indianapolis Motor Speedway (IMS) which, although paved now, used to have a brick surface. The track hosts the Indy 500 and NASCAR's Brickyard 400.
    BURN OFF
    Burning fuel during the course of a race. As fuel is burned, the car becomes lighter and its handling characteristics change, challenging the driver and crew to make adjustments to achieve balance.

    C

    CADENCE BRAKING

    An advanced driving technique used to allow a car to both steer and brake. It is accomplished by pulsing the brake pedal to alternate between wheel lock-up and wheel rotation. This method is not as effective as threshold braking.
    CAMBER
    The angle that wheels are tilted inward or outward from vertical. If the top of the wheel is tilted inward, the camber is negative.
    CART
    Acronym for Championship Auto Racing Teams Inc., the sanctioning organization for the PPG CART World Series.
    CASTER
    Another measure of chassis tuning related to the front wheels. The front wheels are attached to the suspension at the top and bottom of the wheel assembly. The top attachment is typically set a little farther back than the lower attachment, creating caster. The more caster used, the more the wheel resists turning forces, providing stability. Too much caster makes it very difficult to steer, and causes the tire camber to change significantly as the wheel is turned. Not enough caster results in the front end "wandering," or trying to turn on its own.
    CENTER OF PRESSURE
    The point on a Indy car under-wing which receives the greatest amount of airflow pressure. This measurement is critical to setting front to rear balance, especially on superspeedways.
    CHASSIS
    The basic structure of a race car to which all other components are attached. Indy cars have carbon-fiber monocoque "tubs" while a NASCAR stock car has a steel tube frame chassis.
    CHASSIS ROLL
    The up-and-down movement caused when a car travels around corners at high speeds. The side of the car facing the turn becomes lighter while the extra weight goes toward the outside of the turn.
    CHECKED OUT
    Expression when the leader drives away from the rest of the field and will seem impossible to catch.
    CHECKERED FLAG
    The black and white checkerboard style flag which signifies the end of a race.
    CHICANE
    A man-made corner set up to reduce speed at a certain point on a road track. Also referred to as "esses"."
    CHUNKING
    A softer compound rain tire will shed pieces of rubber if a track becomes too dry.
    CHUTE
    A straightaway.
    CIRCUIT
    Any race track. Also refers to the entire slate of races on a season schedule.
    CIRCULATING
    Driving around a track with a damaged and/or slow car to accumulate laps and, more importantly, points and prize money.
    CLEAN AIR
    Air without turbulence created in the wake of other race cars. Clean air is found at the very front of the field.
    CLIPPING
    Minor contact between race cars. Also often refers to hitting precisely, or "clipping," the apex of a turn.
    CLOSED-WHEEL CARS
    The suspension, wheels and tires are mostly covered by the body. Production-based race vehicles such as NASCAR stock cars are examples of closed-wheel cars as opposed to open-wheel "formula" cars.
    COCKPIT
    The area where the driver sits in a race car.
    COLLECTED
    When a car is caught in an incident that they did not cause. If a car spins and is struck by a second car to a stop, the second car is said to be collected.
    COMBINATIONS
    Combinations of engine, gearing, suspension, aerodynamic parts, and wheel and tire settings which teams forecast will work under varying conditions and tracks. These combinations (also known as set-ups) are recorded and used as baseline when teams arrive at a track.
    COMPOUND
    The rubber blend for tires. In some series, teams can choose their tire compound based on the track and weather conditions. A softer compound tire provides better traction but wears out much faster than a harder compound tire which doesn't provide as much grip.
    COMPROMISE CORNER
    See Type 3 Corner.
    CONSTANT RADIUS CORNER
    A corner in which the turning radius is constant.
    CONTACT PATCH
    The small portion of the tire that makes contact with the racing surface. This is one of the more important elements of a driver’s success, different modifications to the car’s body and tires can help the driver get a good contact patch.
    CORNER WORKER
    Volunteers who staff corners to notify drivers of any dangerous situations in the area.
    COSWORTH

    DATA AQUISITION
    Teams use sophisticated sensors, transmitters, computers and software to provide information on what the car and the driver are doing. Everything from engine stress to the driver's heartbeat can be monitored. The information is analyzed to improve handling, performance and even driver technique. Data can be acquired by connecting a computer to the car or by wireless telemetry. In sim-racing, this data is recorded during a race and is accessible to be analyzed, sometime with additional software, much like in real racing.

    DQ
    Disqualified from the event. Usually for safety reasons, the car not meeting certain standards, or for negative behavior.
    DRAFTING
    The aerodynamic effect that allows two or more cars traveling nose-to-tail to run faster than a single car. When one car follows another closely, the one in front cuts through the air, providing a cleaner path of air and less resistance for the car in back.
    DRAG
    A term used in auto racing that relates to anything that causes wind resistance or affects the aerodynamics of air flow over the race car.
    DRIFT or DRIFTING
    A controlled, four-wheel slide through a turn, to get a car line up for a straightaway with a minimum of steering.

    PIT LANE
    See Pit Row
    PIT LIZARD
    Nickname for a racing groupie.
    PIT ROW or PIT ROAD
    The area designated for teams to set up temporary garages during races accessible to ("pit out") and from ("pit in") the track. Each team is allotted one pit area (or space) per car. Drivers pit so crews can refuel, change tires and make any other repairs or adjustments. Simply called the pits most often.
    PIT STOP
    An integral part of most racing series where drivers stop in pit row so their crews can change tires, refuel, and make repairs or other adjustments.
    PITS
    Short for pit row or a dejected driver. Also see hot pits for cold pits.
    PLOW
    See understeer.
    POINT PAYING

    POINTS RACE
    The overall competition to win the Drivers' or Manufacturers' Championship at the end of the season.
    POLE POSITION
    The favored position when the race begins. The pole position is located on the inside of the front row. The driver with the fastest qualifying time is awarded the pole position and the cars are lined up from the pole in order of the fastest to the slowest qualifying lap times.
    POP-OFF VALVE
    In Indy-style racing, this valve is connected to the plenum exiting the turbocharger. Many racing groups supplies these valves in order to restrict the pressure generated by the turbocharger.
    POWER PLANT
    Commonly used term for engines.
    PROVISIONAL STARTING SPOT
    Special performance-based exemptions for drivers who do not initially qualify for a race. A driver awarded a provisional spot must start at the back of the starting grid.

    Q

    QUALIFIERS OR QUALLIES
    Softer compound tires designed for qualifying only because they provide excellent traction but only for a very short amount of time.

    RACER'S TAPE
    Heavy duty duct tape used to temporarily repair hanging body parts which might hinder aerodynamic features and decrease performance. Most commonly used on stock cars (e.g. NASCAR Winston Cup) which use more paneling than Indy-style cars and are accustomed to more contact.
    RACING LINE
    See groove
    RAIN TIRES
    Softer compound with better tread for wet-weather conditions. In dry conditions, these softer tires wear faster than harder compound tires with less tread.
    REBOUND
    In shock absorbers, a rebound adjustment is a change to the dampening of the shock on the expansion stroke. Without rebound dampening, the car would tend to bounce as it passes over bumps on the track. Rebound adjustments can also affect how the weight of the car shifts around during braking, acceleration and cornering.
    RED FLAG
    When displayed at the start/finish line, a red flag signifies an immediate halt of the session due to a dangerous condition such as a flooded track or a car blocking the track. Corner workers around the track will display black flags when this happens, and all cars are required to stop racing and slowly return to the pits. The lap in progress is discarded, and the field reverts to the order of the previous lap when racing resumes. If the race has run more that 50 percent of the laps, the chief steward has the option to declare a complete race if track conditions are not expected to improve. If a race has run less than 50 percent, it will be concluded on another date.
    RED AND YELLOW FLAG
    This striped flag is displayed by corner workers to signify debris (oil, sand, water or some other substance) on the track.
    RESTART
    In sim racing, when a majority of the racers choose to restart, usually after a bad accident which puts most of the cars out of the race.
    RESTRICTOR PLATE
    A stainless steel plate used between the carburetor and the intake manifold to limit the amount of fuel and air reaching the engine. It is used to slow down the race cars on certain high speed NASCAR tracks like Daytona Speedway.
    RETURN
    A vertical flap attached to a Indy car wing for increased downforce. Please see Gurney Flap.
    REV
    To gun an engine. As a noun, "revs" is short for "revolutions per minute."
    REV LIMITER
    Modern engines are controlled by electronic "mapping" software that controls things such as fuel consumption and ignition timing. Rev limiting is used for two purposes: to keep the engine from exceeding its maximum rotational speed and exploding into bits of very expensive shrapnel, and to adhere to speed limit rules in the pit lane. Maximum rev limits are set by the engine manufacturer, while the pit lane rev limiter is controlled by a pushbutton on the steering wheel.
    RIDE HEIGHT
    The distance from the bottom of the chassis to the ground when the car is at full speed. This is regulated at a distance of two inches off the ground. The lower the ride height, the lower the center of gravity which improves handling. Lower ride height may also mean less suspension travel which can cause loss of control when driving over bumps.
    RIDING THE RAILS
    Taking the outside line around a turn.
    ROAD COURSE
    A race track with multiple left and right hand turns. Generally refers to permanent, purpose-built racing facilities. Can also refer to temporary street courses built on big city streets which were popularized in the 1980's.
    ROLL BAR
    Large, sturdy bars designed to protect a driver's head if the car rolls over. Very functional in race cars but used more for style in production cars. Most production and race cars use anti-roll (or sway) bars as part of the suspension to prevent the excessive rolling in corners.
    ROLLING START
    The race begins after the pace car leaves the track while the cars are moving. Formula One opts for a standing start where the cars start from a standstill.
    ROUNDY ROUND
    A slang term in NASCAR used to describe an oval track.
    RUBBING
    Racing announcers use this describe cars that make contact but don't crash. Also called "pushing and shoving."
    RUNNING ANYWHERE
    A car is handling so well, a driver can use any racing line (or drive anywhere.) Sometimes, handling problems lead to a preferred line where the car handles better.
    RUNNING LIGHT
    A car is running with little fuel. Teams qualify with a light load to achieve maximum speed.

    SHUNT
    British term for crash or accident.
    SHUT DOWN
