How much downforce does a Top Fuel dragster exhaust make?

Top Fuel racing 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.

How do dragsters do burnouts?

They also clean the tire of any debris and lay down a layer of rubber by the starting line for better traction. Drag race tracks sometimes use a specially-reserved wet-surface area known as the “water box”, because water is poured onto a certain area to reduce the friction to initiate the burnout.

A burnout means the car is on at a standstill while the tyres spin. But also the rubber can be burning while the car is spinning in circles. This manoeuvre is called a “donut”. Basically, a donut is a sharp corner taken at full-throttle.

What size engine does a Top Fuel dragster have?

A Top Fuel Dragster—distinguished by a supercharged, custom-built, 500-cubic-inch engine—boasts 11,000 horsepower and burns nitromethane. By contrast, a Top Alcohol Dragster’s output is about approximately 4,000 hp. Most alcohol dragsters burn methanol, although a few burn ethanol.

How do Top Fuel dragsters work?

How a Top Fuel Dragster Works. In Top Fuel cars, the engine is situated behind the driver, but Funny Cars put the engine up front. Funny Cars use the wheelbase of a production car from the model year 2000 or later, and then a fiberglass replica of the body is constructed to reduce weight. The rules for using production cars offer a lot of leeway.

Do dragsters use line-locks for burnouts?

I realized that dragsters don’t use line-locks for their burnouts; they roll through the water and just stab the throttle in high gear to get the rears spinning. The car doesn’t sit there stationary; it moves forward immediately and the driver is out of the throttle pretty quickly.

Why do NHRA dragsters use parachutes to slow the car?

Top Fuel dragsters use two parachutes to slow the car after a blistering high-speed pass. (Photo by Mark J. Rebilas/Geiger Media Global) Even though whoever gets to the finish line first is crowned the victor of an NHRA drag race, that doesn’t mean the winning car is necessarily the fastest. It also doesn’t mean that car is the quickest.
