DRAG RACING is a type of motor racing in which automobiles or motorcycles (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly ¼ mile (1,320 ft (402 m)), with a shorter 3/16 mile 10 feet (1,000 ft (305 m)) becoming increasingly popular, as it has become the standard for nitromethane-powered Top Fuel dragsters and funny cars , where some major bracket races and other sanctioning bodies have adopted it as the standard, while 660 ft (201 m) (1/8 mi) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing , and as an organized and regulated motorsport . This article covers the legal sport.

BASICS OF DRAG RACING

Before each race (commonly known as a pass), each driver is allowed to perform a burnout , which heats the driving tires and lays rubber down at the beginning of the track, improving traction. Each driver then lines up (or stages) at the starting line.

Modern professional races are started electronically by a system known as a Christmas tree , which consists of a column of lights for each driver/lane, and two light beam sensors per lane on the track at the starting line. Current NHRA
NHRA
trees, for example, feature one blue light (split into halves), then three amber, one green, and one red. When the first light beam is broken by a vehicle's front tire(s), the vehicle is "pre-staged" (approximately 7 inches (180 mm) from the starting line), and the pre-stage indicator on the tree is lit. When the second light beam is broken, the vehicle is "staged", and the stage indicator on the tree is lit. Vehicles may then leave the pre-stage beam, but must remain in the stage beam until the race starts.

Once one competitor is staged, their opponent has a set amount of time to stage or they will be instantly disqualified, indicated by a red light on the tree. Otherwise, once both drivers are staged, the system chooses a short delay at random (to prevent a driver being able to anticipate the start), then starts the race. The light sequence at this point varies slightly. For example, in NHRA
NHRA
Professional classes, three amber lights on the tree flash simultaneously, followed 0.4 seconds later by a green light (this is also known as a "pro tree"). In NHRA
NHRA
Sportsman classes, the amber lights illuminate in sequence from top to bottom, 0.5 seconds apart, followed 0.5 seconds later by the green light (this is also known as a "sportsman tree" or "full tree"). If a vehicle leaves the starting line before the green light illuminates, the red light for that lane illuminates instead, and the driver is disqualified (also known as red lighting). In a handicap start, the green light automatically lights up for the first driver, and the red light is only lit in the proper lane after both cars have launched if one driver leaves early, or if both drivers left early, the driver whose reaction time is worse (if one lane has a -.015 and the other lane has a -.022, the lane of the driver who committed a 0.022 is given the red light after both cars have left)., as a red light infraction is only assessed to the driver with the worse infraction, if both drivers leave early. Even if both drivers leave early, the green light is automatically lit for the driver that left last, and they still may win the pass (as in the 2014 NHRA
NHRA
Auto Club Pro Stock
Pro Stock
final, Erica Enders-Stevens and Jason Line both committed red light infractions; only Line was assessed with a red light, as he was -.011 versus Enders-Stevens' -.002).

Several measurements are taken for each race: reaction time, elapsed time, and speed. Reaction time is the period from the green light illuminating to the vehicle leaving the starting line. Elapsed time is the period from the vehicle leaving the starting line to crossing the finish line. Speed is measured through a speed trap covering the final 66 feet (20 m) to the finish line, indicating average speed of the vehicle in that distance.

Except where a breakout rule is in place, the winner is the first vehicle to cross the finish line, and therefore the driver with the lowest combined reaction time and elapsed time. Because these times are measured separately, a driver with a slower elapsed time can actually win if that driver's advantage in reaction time exceeds the elapsed time difference. In heads-up racing, this is known as a holeshot win. In categories where a breakout rule is in effect (for example, NHRA
NHRA
Junior Dragster, Super Comp, Super Gas, Super Stock, and Stock classes, as well as some dial-in classes), if a competitor is faster than his or her predetermined time (a "breakout"), that competitor loses. If both competitors are faster than their predetermined times, the competitor who breaks out by less time wins. Regardless, a red light foul is worse than a breakout, except in Junior Dragster where exceeding the absolute limit is a cause for disqualification.

Most race events use a traditional bracket system, where the losing car and driver are eliminated from the event while the winner advances to the next round, until a champion is crowned. Events typically use 4, 8, or 16 car brackets. Drivers are typically seeded by elapsed times in qualifying. In bracket racing without a breakout (such as NHRA
NHRA
Competition Eliminator), pairings are based on times compared to their index (faster than index for class is better). In bracket racing with a breakout (Stock, Super Stock, but also the NHRA's Super classes), the closest to the index is favourable.

A popular alternative to the standard eliminations format is the Chicago Style format (also called the Three Round format in Australia), named for the US 30 Dragstrip in suburban Gary, Indiana where a midweek meet featured this format. All entered cars participate in one qualifying round, and then are paired for the elimination round. The two fastest times among winners from this round participate in the championship round. Depending on the organisation, the next two fastest times may play for third, then fifth, and so forth, in consolation rounds. Currently, an IHRA 400 Thunder championship race in Australia uses the format.

The standard distance of a drag race is 1,320 feet, 402 m, or 1/4 mile. However, due to safety concerns, certain sanctioning bodies (notably the NHRA
NHRA
for its Top Fuel
Top Fuel
and Funny Car
Funny Car
classes) have shortened races to 1,000 feet. Some drag strips are even shorter and run 660 feet, 201 m, or 1/8 mile. The 1,000 foot distance is now also popular with bracket racing, especially in meets where there are 1/8 mile cars and 1/4 mile cars racing together, and is used by the revived American Drag Racing League for its primary classes (not Jr Dragster). Some organisations that deal with Pro Modified and "Mountain Motor" Pro Stock
Pro Stock
cars (Professional Drag Racers Association) use the 1/8 mile distance, even if the tracks are 1/4 mile tracks. An early example, a 1958 Fuel dragster (technically, a rail ), on display at the California Automobile

NORTH AMERICA

The National Hot Rod Association
National Hot Rod Association
(NHRA) oversees the majority of drag racing events in North America. The next largest organization is the International Hot Rod Association (IHRA). Nearly all drag strips are associated with one sanctioning body or the other.

Besides NHRA
NHRA
and IHRA, there are niche organizations for muscle cars and nostalgia vehicles. The Nostalgia Drag Racing League (NDRL) based in Brownsburg, IN, runs a series of 1/4 mile (402m) drag races in the Midwest for 1979 and older nostalgic appearing cars, with four classes of competition running in an index system. Pro 7.0 and Pro 7.50 run heads up 200 mile per hour (320 kilometre per hour) passes, while Pro Comp and Pro Gas run 8.0 to 10.0 indices. NDRL competition vehicles typically include Front Engine Dragsters, Altereds, Funny Cars, early Pro Stock
Pro Stock
clones, Super Stocks and Gassers.

The National Electric Drag Racing Association (NEDRA) races electric vehicles against high performance gasoline-powered vehicles such as Dodge Vipers

CLASSES

Caterpillar-sponsored dragster. Note wide slicks and high-mounted wing, to assist traction.

There are hundreds of classes in drag racing, each with different requirements and restrictions on things such as weight, engine size, body style, modifications, and many others. NHRA
NHRA
and IHRA share some of these classes, but many are solely used by one sanctioning body or the other. The NHRA
NHRA
boasts over 200 classes, while the IHRA has fewer. Some IHRA classes have multiple sub-classes in them to differentiate by engine components and other features. There is even a class for aspiring youngsters, Junior Dragster , which typically uses an eighth-mile track, also favored by VW racers.

In 1997, the FIA (cars) and UEM (bikes) began sanctioning drag racing in Europe with a fully established European Drag Racing Championship, in cooperation (and rules compliance) with NHRA. The major European drag strips include Santa Pod Raceway in Podington, England; Alastaro Circuit, Finland; Mantorp Park, Sweden; Gardermoen Raceway, Norway and the Hockenheimring in Germany. The major difference is the nitro-class distance, which is 300 meters at some tracks, although the NHRA
NHRA
and FIA are likely to discuss the distance change in the future. Pain Killer J/D. Note the driver, helmet off, is still in the car, which is under tow on the return road, headed for the pits.

There is a somewhat arbitrary definition of what constitutes a "professional" class. The NHRA
NHRA
includes 5 pro classes; Top Fuel, Funny Car, Pro Stock, Pro Modified and Pro Stock
Pro Stock
Motorcycle. The FIA features a different set of 5 pro classes; Top Fuel, Top Methanol Dragster, Top Methanol
Methanol
Funny Car, Pro Modified and Pro Stock. Other sanctioning bodies have similarly different definitions. A partial list of classes includes: Fuel dragsters

* Top Fuel
Top Fuel
Dragster (TF/D). The rail dragsters, or "diggers", are the fastest class. Among the fastest-accelerating machines in the world, these cars can cover the dragstrip in less than 3.8 seconds and record trap speeds over 325 mph. Top Fuel

* Pro Stock
Pro Stock
(NHRA, IHRA/MMPSA) Often called “factory hot rods” because of their resemblance to production-based cars (and because they must maintain a relatively stock appearance), commonly called "doorslammers", Pro Stockers can record quarter-mile times in the 6.4 second range, and speeds over 210 mph. They can rev to more than 10,500 rpm and make in excess of 1,300 horsepower. NHRA
NHRA
engines can be no more than 500-cubic-inch (8.2 L) displacement while IHRA/MMPSA cars can run a maximum of 820 cubic inches (13.4 L) (called "Mountain Motors"). Both classes require the motors to be naturally aspirated. * Pro Stock

Cars can run superchargers, turbochargers, or nitrous oxide. Cars running blowers are limited to 527 cubic inches (8.6 L) while cars with nitrous can run up to 740 cubic inches (12.1 L). This class is globally recognised, although the name differs between North America and Australia. * Top Alcohol Dragster (TA/D). Known as Top Methanol
Methanol
Dragster in FIA competition. Top Alcohol Dragsters resemble Top Fuelers, but have significant differences. They may use a supercharged methanol-burning engine or an injected nitromethane combination. They can run in the 5.1s at more than 280 mph. * Top Alcohol Funny Car

A typical Comp car.

* Competition Eliminator This is the NHRA
NHRA
class with the most variety. Each of its 88 sections is assigned an index based on what a well-built car should run, and races are handicapped according to those indexes. * Outlaw Series * Pro FWD * Super Comp/Quick Rod The quickest of the heads-up Super classes (8.90 index) is composed primarily of dragsters. Most cars are capable of running well under the index but use electronic aids to run close to it without breaking out.

Super Gas Probe.

* Super Gas/Super Rod Super Gas entries, which run on a 9.90 index, are primarily full-bodied cars and street roadsters. No dragsters or altereds are permitted. As in Super Comp, competitors use electronic aids to run as close to the class standard without going under. * Super Street/Hot Rod Racers compete on a fixed 10.90 index. All vehicles must be full-bodied cars and weigh no less than 2,800 pounds except for six-cylinder cars (2,000) and four-cylinder and rotary-powered cars (1,200). Engine and chassis modifications are virtually unlimited. Super Street Mustang

A typical Super Stock car

* Super Stock Super Stock vehicles resemble ordinary passenger cars, but are actually heavily modified. Entries are classified using factory shipping weight and horsepower and compete on indexes. The breakout rule is enforced. * Stock Stock cars are similar to Super Stockers, but rules regarding everything from engine modifications to body alterations are much stricter. Virtually any car is eligible to compete, and entries are classified using factory shipping weight and horsepower. * Sport Compact * Top Sportsman ( NHRA
NHRA
and IHRA) Competitors in these full-bodied entries may choose their own dial for eliminations, generally from 6.00 to 7.99 seconds. Full Tree starts are used, and the breakout rule is enforced. Cars can run in the sixes at more than 200 mph.

Blown Top Dragster

* Top Dragster ( NHRA
NHRA
and IHRA) Competitors in these open-wheel entries may choose their own dial for eliminations, generally from 6.00 to 7.70 seconds. Full Tree starts are used, and the breakout rule is enforced. Cars can run in the sixes at more than 200 mph. Cars can run any combination of motor: blown, turbo, nitrous or just all motor. * Top Fuel

Dragster. Juniors run as following: 12.90-slower for 8-9 year olds, 10-12 year olds at 8.90, and 13-18 year olds 7.90 and slower at a top speed of 85 mph). These cars race at 1/8 mile or 1/16 mile. * NHRA
NHRA
new class for Juniors is JR COMP running 6.90s at a top speed of 110 miles per hour (180 km/h) (1/8 mile or 1/16 mile).

To allow different cars to compete against each other, some competitions are raced on a handicap basis, with faster cars delayed on the starting line enough to theoretically even things up with the slower car. This may be based on rule differences between the cars in stock, super stock, and modified classes, or on a competitor's chosen "dial-in" in bracket racing .

For a list of drag racing world records in each class, see Dragstrip#Quarter mile times .

DIAL-IN

A "dial-in" is a time the driver estimates it will take his or her car to cross the finish line, and is generally displayed on one or more windows so the starter can adjust the starting lights on the tree accordingly. The slower car will then get a head start equal to the difference in the two dial-ins, so if both cars perform perfectly, they would cross the finish line dead even. If either car goes faster than its dial-in (called breaking out), it is disqualified regardless of who has the lower elapsed time; if both cars break out, the one who breaks out by the smallest amount wins. However, if a driver had jump-started (red light) or crossed a boundary line, both violations override any break out (except in some classes with an absolute break out rule such as Junior classes). This eliminates any advantage from putting a slower time on the windshield to get a head start. The effect of the bracket racing rules is to place a premium on consistency of performance of the driver and car rather than on raw speed, in that victory goes to the driver able to precisely predict elapsed time, whether it is fast or slow. This in turn makes victory much less dependent on large infusions of money, and more dependent on skill. Therefore, bracket racing is popular with casual weekend racers. Many of these recreational racers will drive their vehicles to the track, race them, and then simply drive them home. As most tracks host only one NHRA
NHRA
national event, and two or three regional events (smaller tours, car shows, etc.) annually, on most weekends these tracks host local casual and weekend racers. Organizationally, however, the tracks are run according to the rules of either the NHRA or the IHRA with regional points and a championship on the line. Even street vehicles must pass a safety inspection prior to being allowed to race. Blazing Angel Jet Dragster

HISTORY

The National Hot Rod Association
National Hot Rod Association
(NHRA) was founded in 1951, to take illegal racing off the street .

The organization banned the use of nitromethane in 1957, calling it unsafe, in part through the efforts of C. J. Hart ; the ban would be lifted in 1963.

* Back half—distance from the 1/8 mile mark to the 1,000 foot and 1/4 mile mark of the track. * Beam—starting line electric eye controlling prestaged and staged lights. * Bottle—nitrous system; also known as the jug. * Blanket—a ballistic cover, typically over the supercharged intake manifold assembly to contain shrapnel, in the case of an explosion. * Blow—see Blown. * Blower—supercharger (occasionally turbocharger ); in '90s, generally grouped as "power adder" with turbocharger and nitrous * Blown—supercharged, when describing a functioning engine; wrecked, when describing an engine failure. * Blowover—flipping of a car, due to air under car lifting front wheels. Commonly suffered by dragsters * Breakout—running quicker than dial-in; also "breaking out." In many classes (Competition Eliminator is the major exception), it is grounds for disqualification if opponent does not commit a foul start, cross boundary lines, or breaks out by a larger margin. * Bulb(ed)—jump(ed) the start, left before tree turned green. This is a loss unless the opponent suffers a more serious foul. * Burnout—performed to heat the tires up for better traction * Christmas tree (or tree)—lights used to start a race in addition to showing starting violations * DA—density altitude; a reference to qualities in the air. * Dial-in (bracket racing)—estimated of expected e.t. for a pass, set before starting, used for handicapping the start * Diaper—an absorbent containment blanket under the engine to prevent/reduce oil contact with the track, in the event of parts breakage * Dope—(Southern U.S.) car using nitrous or propane injection on diesels * Digger—dragster (as distinct from a bodied car or flopper) * First or worst —if both drivers commit a foul, the driver who commits the foul first loses, unless it is two separate fouls, where the loser is the driver who committed the worse foul (lane violation is worse than foul start, and failure to participate in a post-run inspection is worst). * Flopper—Funny Car, short for "fender flopper." Coined by dragster crews in the late 1960s to separate Funny Cars, which had fiberglass bodies with fenders, from dragsters. Erroneously attributed to flip-top bodies of Funny Cars. * Fuel—mix of methanol and nitromethane ("pop," nitro); race class using it * Fueler—any car running fuel or in Fuel class (most often, TFD or TF/FC) * Grenade—wreck an engine (the engine "grenaded") due to internal failure. Distinct from "popping a blower". * Heads-up racing—where both drivers leave at the same time. Used in all professional ("pro") classes. * Holeshot—getting a significant advantage off the starting line. The other driver gets "holeshotted" or "left at the tree". A "holeshot win" is any win in a heads-up class where a slower car beats a faster car because of better reaction time . * Hook up—good traction between tires and track resulting in increased acceleration and reduced slipping or smoking of tires. * James Bond—driver's reaction time (when he leaves the starting line) is seven thousandths of a second after the green light (.007). A "James Bond Red" is a reaction time of -.007 seconds (red light), which is disqualification unless the opponent commits a more serious violation. * Kit—turbo or nitrous kit * Lit the tires—lost traction, causing burning rubber * Meth—methanol injection used in conjunction with gasoline (non-leaded pump) * Mill—any internal combustion engine used in a drag car, or hot rod * Nitro—nitromethane (sometimes incorrectly used to refer to nitrous oxide) * Nitrous—nitrous oxide system; the gas used in such a system * Overdrive—ratio between the revolutions of the supercharger to the revolutions of the engine, controlling amount of boost; see underdrive * Oildown—when a car's engine or lubrication breaks during a run, leaving a streak of oil and other fluids on the track. This is punishable by fines, point penalties, and/or suspension. * Pedalfest—race won by pedalling; or poor track conditions that necessitate pedalling * Pedalling—working the throttle to avoid lighting the tires, or as a way to sandbag; "pedalled" it, had to "pedal" it * Pro tree—timing lights which flash all three yellow lights simultaneously, and after four tenths of a second, turn green. * Put on the trailer—lost (got "put on the trailer") or won (put the other driver on the trailer). From the obvious, losing drivers trailer their cars home. * Quick 8 (Q8)—quickest eight cars in a defined race. Rules appear to differ per location/race. * Rail—dragster (as distinct from bodied car or flopper). From the exposed frame rails of early cars. * Redlight(ed)—jump(ed) the start, left before tree turned green. This is a loss unless the opponent commits a more serious foul. * Red Cherry-jump(ed) the start, left before the tree turned green. * Sandbagging—releasing the throttle or using the brakes at the end of the track during a bracket race after dialing a purposely slow time. Considered a dirty trick or tantamount to cheating in amateur classes. * Scattershield—metal sheet protecting driver in case of transmission failure * Slapper bar—traction bar * Slicks—rear tires with no tread pattern and softer rubber compound, for increased traction * Slingshot—early front-engined dragster, named for the driving position behind the rear wheels (erroneously attributed to launch speed). * Standard tree—timing lights which flash in sequence five tenths of a second between each yellow light before turning green. Traditional form, before introduction of pro tree. * Struck the tires—loss of traction, causing them to smoke * Throw a belt—losing the drive belt connecting the engine's crankshaft to the supercharger * Top end—finish line of strip; high part of engine's rev band. * Traction bars—rear struts fixed to rear axle to keep rear axle from twisting, causing wheel hop and loss of traction; slapper bars. * Trap(s)—the 20-metre (66 ft) timing lights at top end of race track to measure speed ">
