Drag racing is a type of motor racing in which any type of automobile (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line for a small distance. 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)) used by nitromethane powered Top Fuel dragsters and funny cars along with some bracket races, 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.
People today do drag racing of bikes and cars and trucks along with other cars as a type
of street racing lawfully and illegally being an organized and controlled
motorsport. This post covers the legal Activity.

Top rated Fuel
Amongst the quickest-accelerating machines on the globe, ten,000-horsepower
Top rated Gasoline dragsters in many cases are known as the “kings from the Activity,”
and with fantastic cause. They’re effective at covering the dragstrip in considerably less
than 3.7 seconds at more than 330 mph. Powered by a supercharged and
gas-injected 500cubic-inch adaptation in the famed Chrysler Hemi
engine, Best Fuel dragsters can burn up to fifteen gallons of nitromethane
gasoline all through just one run. Produced of chromoly metal tubing and
carbon-fiber composite, Major Gasoline autos are 25 ft prolonged and weigh two,330
pounds in race-Completely ready trim.
Comparable to their Leading Fuel counterparts but by using a shorter wheelbase and
a carbon-fiber system that loosely resembles a manufacturing-primarily based
automobile, Funny Vehicles can operate during the 3.8-2nd selection and so are capable
of speeds in surplus of 330 mph. Humorous Automobiles are run by the same
supercharged and gasoline-injected five hundred-inch engines as Top Gasoline dragsters.
Amusing Automobiles are also just like Top Gasoline dragsters in that they don’t
use a transmission but fairly transmit electric power to the huge Goodyear rear
slicks by way of a multistage clutch assembly that is activated by timers.
Typically known as “manufacturing unit hot rods” as a result of their resemblance to
output-dependent vehicles, Professional Inventory autos are a few of the most
technologically Superior machines in drag racing. Developed all-around a
complex tube chassis and four-backlink rear suspension, Pro Inventory cars
will have to conform to exact measurements and weigh no under 2,350
pounds. Pro Inventory engines use electronic gas injection and spec
gasoline and are limited to the maximum of five hundred cubic inches. They will
make in surplus of one,300 horsepower. A competitive Professional Stock auto can run
during the 6.4s at greater than 215 mph.
Pro Stock Motorcycle
These remarkably modified automobiles, which might run below 6.8 seconds at extra
than 195 mph, attribute a reason-crafted tube chassis and a light-weight,
aerodynamically Improved replica of first bodywork. The category
capabilities lots of would make, models, and engines, together with V-Twin
entries from Harley-Davidson, Victory, EBR, and Buell and inline
four-cylinder-equipped Suzuki and Kawasaki products. Engine measurements vary
commonly, ranging from ninety two to a hundred and sixty cubic inches. Gasoline injection is
permitted, and spec gasoline is the sole gas authorized.
Top Alcohol Dragster
Top Alcoholic beverages Dragsters may seem like Top rated Fuelers, but they have
significant distinctions. Whilst Top Fuelers use supercharged,
nitro-burning engines, Top rated Alcoholic beverages Dragsters may possibly make use of a supercharged
methanol-burning engine or an injected nitromethane mixture. The
injected nitro autos don’t utilize a transmission, along with the supercharged autos
have 3 ahead speeds. Weights change In keeping with blend but
are generally involving one,975 and a pair of,125 pounds. Like Leading Fuelers, Top rated
Alcohol Dragsters are limited into a greatest wheelbase of 300 inches.
Performances could be during the five.1s at much more than 285 mph.
Top Alcohol Funny Car
Equivalent in Bodily visual appeal for their nitro-burning Humorous Motor vehicle
counterparts, Top rated Liquor Funny Automobiles are restricted to using
methanol fuel and also have A 3-pace transmission. Top rated Liquor Humorous
Autos feature in essence exactly the same chromoly metal chassis given that the nitro vehicles
and so are fitted with the exact same carbon-fiber replica bodies, while the
Leading Liquor Amusing Car or truck bodies will not want as much downforce and make use of a
Substantially scaled-down rear spoiler. Top rated Alcohol Funny Automobiles are capable of
performances inside the five.3s at greater than 270 mph.
No classification in NHRA Opposition attributes additional wide range than Comp.
Dragsters, altereds, street roadsters, coupes, sedans, front-motor
nostalgia dragsters, sport compact autos, and vehicles race in seventy five courses.
The engine combos are only as numerous as being the cars, from
turbocharged four- and six-cylinder engines to Professional Stock-style V-8s and
nitrous-oxide-Outfitted mountain motors. Most automobiles are classified using a
components that divides overall car or truck weight by cubic inches. Every class is
assigned an index depending on what a effectively-built motor vehicle need to run, and races
are handicapped In line with People indexes.
Super Inventory automobiles may perhaps appear like normal passenger vehicles, but
They can be remarkably modified race cars. The class functions generally
late-model sedans and vintage muscle cars and trucks, and entries are labeled
employing a process that divides manufacturing unit shipping and delivery weight by NHRA-factored
horsepower. Significant engine modifications are permitted, however the
auto should keep the right engine block, cylinder heads, and
carburetor. Automobiles are handicapped employing an index system, along with the breakout
rule is enforced.
Inventory autos are comparable to Super Stockers, but The principles about
every thing from motor modifications to system alterations are much
stricter. Just about any auto is suitable to compete, and entries are
categorized employing a process that divides manufacturing facility shipping and delivery weight by
NHRA-factored horsepower. Bodies need to be unaltered and keep an entire
manufacturing facility inside. Tires are limited to a optimum nine-inch-vast rear slick.
Engines should be suitable for that make and model automobile and will have to keep
inventory cylinder heads, consumption manifold, and carburetor. Modifications are
restricted to a fundamental balancing and rebuild with only some overall performance
The fastest in the heads-up Tremendous classes (eight.90 index), Super Comp is
composed generally of dragsters. Engine, chassis, and system modifications
are virtually unlimited. Four- and six-cylinder-driven entries could
Possess a minimum fat of 1,000 pounds; all Other individuals are unable to weigh lower than
1,350 kilos. Most Super Comp cars are able to functioning very well beneath
the 8.90 index but use several electronic aids, like a timer
and adjustable throttle, to run close to the index without the need of operating
more quickly than it, or breaking out.
Tremendous Gas entries, which operate on a 9.90 index, are mostly complete-bodied
cars and trucks and Road roadsters. No dragsters or altereds are permitted.
Principles relating to motor and chassis modifications are very liberal,
although the use of exotic fuels is prohibited. The minimum weight is
two,100 kilos except for four-cylinder-run cars and trucks, which can Possess a
minimum body weight of one,two hundred lbs. As in Tremendous Comp, opponents use
electronic timers and throttle stops to operate as near The category
typical without likely beneath. Also as in Tremendous Comp, races are staged
utilizing a 4-tenths Pro commence.
At NHRA Lucas Oil Drag Racing Collection races and select NHRA Mello Yello
Drag Racing Collection situations, Super Road racers contend on a hard and fast
10.ninety-next index. All vehicles has to be total-bodied autos and weigh no
less than 2,800 kilos except for 6-cylinder automobiles, which can Have a very
minimal weight of two,000 kilos, and 4-cylinder- and rotary-driven
vehicles (one,200 lbs). Engine and chassis modifications are practically
unlimited. Racers contend on a 5-tenths Professional Tree.
This group for whole-bodied vehicles features a qualified discipline of 32,
48, or sixty four entries. A standard bracket racing format is used having a
complete a few-amber Christmas Tree start out, along with the breakout rule is
enforced. Entries can run while in the sixes at in excess of two hundred mph.
group for open up-wheel entries functions a qualified industry of 32, 48,
or sixty four autos. A conventional bracket racing structure is made use of which has a full
3-amber Christmas Tree commence, plus the breakout rule is enforced.
Entries can run within the sixes at much more than 200 mph.
With the eclectic mix of cars that range between ’41 Willys coupes to
’sixty three Corvettes to late-product Ford Mustangs and Dodge Vipers, several courses
present just as much range and exhilaration. The motor choices are equally
as varied; competitors can use superchargers, turbochargers, or
nitrous-oxide injection and operate in to the significant-5-2nd zone at speeds
of a lot more than 250 mph. The NHRA J&A Service Professional Mod Drag Racing
Collection operates at 10 NHRA Mello Yello Drag Racing Collection situations.
