Burnout (vehicle)

A saturation (also known as peel out or power brake ) is the practice of keeping the vehicle stationary and spinning the wheels, causing the tires to overheat and smoke because of friction.

History

The origins of burnouts can be traced to drag racing, where they have a practical purpose: drag racing tires perform better at higher temperatures, and fatigue is the fastest way to raise the tire temperature immediately before the race. They also cleaned the tires from the debris and laid rubber layers with a starting line for better traction. Drag racing tracks sometimes use a special-protected wet surface area known as "water box," ie this is because water is poured into certain areas to reduce friction to start "saturation," for this purpose.

Burnouts eventually became a serious form of competition and entertainment in their own right. Large prize money or goods are sometimes involved, and cars can even be sponsored or custom-made as "burning cars". The Burnout contest is judged by audience response, with style and attitude being an important factor. Contests of this kind are very popular in Australia but often occur in North America as well.

Burnouts also often occur in informal street racing, usually for show values. As with all street racing activities, blackouts on public property are illegal in most countries but the severity of punishment varies. In New South Wales, for example, police have the power to confiscate offensive vehicles for 3 months for the first offense. In March 2010, British Formula 1 World Champion Lewis Hamilton made his Mercedes car confiscated for allegedly blackout in Melbourne, Australia when leaving Albert Park Grand Prix Circuit.

Burnout is also often done by winning drivers at the end of the NASCAR race to celebrate their victory.

Practice

Doing a blackout in the front wheel vehicle is likely to cause damage to the drivetrain. This is usually achieved by using the parking brake to lock the rear tire and coat the gas pedal.

To perform a burnout on the rear-wheel drive vehicle, the driver must simultaneously use the accelerator and brake. The brake pedal will require modulation, since the goal is to allow the rear tire to spin while holding the car in place with the front wheels still not moving. At a certain point of balance, the front brake will prevent the car from moving forward while the rear brake does not have enough grip to keep the wheels from spinning, as engine power is transferred to the rear wheels only.

It is possible to make the rear wheel drive easier by installing "channel lock", a device that allows fluid pressure on the front brake to be maintained while removing the pedal to free the rear brake. This is very useful in manual transmission vehicles, which can be very difficult to manipulate the clutch, brake and accelerator simultaneously. The channel lock also reduces wear on the rear brake, a common problem if not.

Burnout is most difficult in four-wheel drive and all-wheel drive cars, as they have better traction than FWD or RWD vehicles. It takes a much more powerful engine to break the four tires at the same time, and the tires will spin just for a while before the four get traction.

Other techniques

Other saturation techniques are intended for cars with insufficient power to perform a burnout from a standing position. This involves placing the car backward, backing up at a higher speed than usual and then quickly putting the car into first gear and hitting the accelerator. This variant is to reverse at an angle which will produce two (for cars with limited slip differential) typical skidmarks of cars pushing forward - in the Arab section of the world, this trick is called "88", as skidmarks resembles two digits-eight in Arabic (" ? "). In the United States these signs are referred to as "fishhooks", a very accurate description of skidmarks as the car will leave a longer mark when the vehicle speed becomes aligned with the forward direction. During this action the vehicle always experiences an acceleration vector (not necessarily constant) pointing along the front of the car, but the velocity vector will reverse direction from initially pointing backwards, leaving the "hook" mark.

At least in the late 1970s in the United States, exhausted fans occasionally coated their steering wheel tires (usually back) with liquid chlorine bleach. This will produce a spectacular spark of white smoke during fatigue.

These and similar techniques are generally not recommended because they place a large load on the drivetrain component and can cause transmission damage. The effective use of steering wheel tires is shortened precisely.

Additional techniques that are sometimes used by those who celebrate race wins (such as in NASCAR) are positioning a racing car so that the nose sticks to the outer wall of the track, helping keep the car in place when the rear wheels are spinning.
