8 They Produce More G-Force Than A Space Shuttle Launch

Blasting off from the starting line in a Top Fuel dragster produces 5 Gs which is more than a fighter jet launch. The g-force produced from Top Fuel dragsters is also more than a space shuttle launch, which only produces 3 G's.

7 They Consume An Unbelievable Amount Of Fuel

Fuel is the most important part of a race car, bringing life to the fiery beast. These cars only race down the track for 3-4 seconds but burn gallons of the liquid gold during that time. Not to mention the burn-out and reversing the car back to the starting line.

6 Top Fuel Engines Are Basically Bombs On Wheels

The excessive amount of horsepower and fuel walk a fine line between perfection and disaster. This is a major reason the engine is rebuilt after each pass. If anything goes wrong inside the engine, fires and explosions are a high probability.

5 The Engine Produces 11,000 Horsepower

How long can a top fuel engine run?

Dynamometers that can measure the output of a Top Fuel engine exist; however, the main limitation is that a Top Fuel engine cannot be run at its maximum power output for more than 10 seconds without overheating or possibly destroying itself explosively.

How many injectors are in a supercharger?

In general 10 injectors are placed in the injector hat above the supercharger, 16 in the intake manifold and two per cylinder in the cylinder head. Usually a race is started with a leaner mixture, then as the clutch begins to tighten as the engine speed builds, the air/fuel mixture is enriched.

What engine is used in top fuel drag racing?

What Does Drag Strip Mean?

A drag strip is a straight section of road that is used for drag racing. The strip is a generally paved track or it could be a traditionally paved road but it must be straight so that the vehicles can be allowed to ‘drag’ over it without the need for corners or added potential for injury.

How Wide is a Drag Strip?

An official drag strip requires at least 25 feet for each lane. While drag strips can, theoretically, be only one lane with measurements taken, they are typically at least two lanes wide. Some strips may even have a total of four lanes for drivers.

Why Are Drag Strips So Sticky?

Drag strips are sticky because they use a special compound to allow for the most impressive launch. This material is typically PJ1 TrackBite or was once known as VHT. It’s designed to get vehicles with large horsepower to achieve a more impressive showing that could otherwise be a bit difficult.

Conclusion

When it comes to drag racing there are a number of factors to consider if you are thinking about racing or even going to watch a race. For those considering starting their own drag strip, there is, even more, to think about, including the size and the materials to do it.

How long is a drag strip?

A dragstrip is a straight, purpose-built racetrack, typically an eighth, ten feet longer than three-sixteenths, or a quarter of a mile long (660/1,000/1320 feet, 201/304.8/402 m), with an additional shutdown area to allow vehicles room to stop after crossing the finish line. Common features also include a 'water box' where vehicles ...

How many feet is a drag track?

Although a quarter mile (1320 feet, 402 m) is the best known measure for a drag track, many tracks are eighth mile (201 m) tracks, and the premiere classes will run 1,000 foot (304.8 m) races. The race is begun from a standing start which allows three factors to affect the outcome of the race: reaction time, power/weight ratio, and traction.

How long does it take to get a drag racer to go through the rules?

These can be found in the applicable governing body's rule book. Most rules do not apply until the vehicle exceeds a specified time, such as 10.99 seconds.

What is the water box on a motorcycle?

Common features also include a 'water box' where vehicles and motorcycles start their burnouts for tire clean-up and also to heat up their tires to improve traction. There is a set of lights known as a 'Christmas Tree' that counts down to the start.

How fast can a dragster go?

The fastest class in the National Hot Rod Association (NHRA) drag-racing series, these cars can rocket to 300 mph in less than 4 seconds. That seemingly physics-defying performance is why Jim Oberhofer, the VP of operations at Kalitta Motorsports, calls top-fuelers violence on wheels.

In the time required to take a sip of coffee, Grubnic's car reaches 248 mph. Some of the clutch plates begin welding together, pulling the engine to its lowest rpm, 6500.

What is a dry clutch?

A five-disc dry clutch is the only link between the engine and the locked rear end —there's no transmission. "The clutch is the lifeline of the car," Oberhofer says, because it regulates wheelspin by gradually engaging and slipping as the car moves down the track. A hydraulically motivated throw-out bearing operates off a simple timer (computer controls are illegal). The clutch is tuned according to track conditions. If it engages too quickly, the tires will spin, but if it's too lazy, the car won't accelerate as fast as possible. The discs get so hot that at least two of them are welded together by the run's end.

How do bias ply tires affect gearing?

The bias-ply tires also dramatically change diameter over a run, which has the effect of altering the overall gearing. At the start, the 36-inch-diameter tires squat as the sidewalls wrap around the wheels' bead locks. With increasing vehicle speed, the tires expand to a final diameter of 44 inches.

Is drag racing a race?

Many of them have likely been fans of the sport for 20, 30, 40 or more years. And many of them believe a drag race is not a race until every class, including Top Fuel and Funny Car, competes at the same length.

Top Fuel racing

Before their run, racers often perform a burnout in order to clean and heat tires. Additionally, the burnout applies a layer of fresh rubber to the track surface, which greatly improves traction during launch.
At maximum throttle and RPM, the exhaust gases escaping from a dragster's open headers produce about 900–1,100 pounds-force (4.0–4.9 kN) of downforce. …

Fuel

Since 2015, NHRA regulations limit the composition of the fuel to a maximum of 90% nitromethane; the remainder is largely methanol. However, this mixture is not mandatory, and less nitromethane may be used if desired. The exhaust gas from nitromethane combustion contains nitric oxide, an important intermediate in industrial chemistry, which is formed in combustion systems and can be generated by lightning in thunderstorms. In mammals, including humans, nitric oxide is a sign…

Top fuel engines

Like many other motor sport formulas originating in the United States, NHRA-sanctioned drag racing favors heavy restrictions on engine configuration, sometimes to the detriment of technological development. In some cases, teams are required to use technologies that may be decades old, resulting in cars that may seem substantially less advanced than the average family car. H…

Mandatory safety equipment

Much of organized drag-racing is sanctioned by the National Hot Rod Association. Since 1955, the association has held regional and national events (typically organized as single elimination tournaments, with the winner of each two car race advancing) and has set rules for safety, with the more powerful cars requiring ever more safety equipment.
Typical safety equipment for contemporary top fuel dragsters: full face helmets with fitted HAN…

History

In 1958, NHRA banned nitro in all categories; the American Hot Rod Association (AHRA) still allowed it, and Fuel Dragsters (FD), Hot Roadsters (HR), and Fuel Coupés (FC): this led to Fuel Altereds (AA/FAs), Factory Experimentals (A/FXs), and (ultimately) Funny Cars (TF/FCs).
Independent drag strips, not NHRA sanctioned, offered venues for the fuel racers. Smokers Car Club hosted the first U.S. Fuel and Gas Championship at Famoso Raceway in March 1959. Bob Ha…
