To perform a burnout in a rear wheel drive vehicle the driver has to simultaneously engage the gas and brake pedals. The brake pedal will require modulation, as the goal is to allow the rear tires to spin while holding the car in place with the front wheels remaining motionless.
Cracks do occur in the belt in all circumstances. They can also be caused by localised stress induced by mechanical damage to the part of the belt that runs through it, for example from threading / crossing splices in the belt, or from belt bending induced by sudden or excessive deceleration or excessive G-loading. In some cases, cracks can be caused by impacts with other parts of the engine. Cracks can also be caused by thermal stresses. Cracks can occur near or in areas where the belt is subject to high tension, particularly in situations where the part of the belt that runs through the crack is subject to a large tension/compressive force. The largest problem with cracked belts is that they tend to break in large sections, and/or fail to grip the sprockets/idlers adequately.
If the crack is contained within a small region of the belt, the belt can usually be changed and the engine returned to service without too much fuss. If it is contained within a larger region of the belt, the drivetrain and/or other parts of the engine may need replacing. It is important to note that not all cracks are due to a problem with the belt itself; many other causes exist. The following are some of the common causes of cracked belts:
In general, cracks in the belt are not a problem unless they break the belt and the belt fails, in which case it can cause damage to other parts of the engine (excessive wear of the sprocket and/or teeth of the pulleys and idlers, which is the worst case scenario), and/or other failures (drivetrain, etc).
Sidacs are only used in the ignition systems of some engines, and are not widely used in the transmission and drive train. They are used in the engine to protect the distributor, reducing the risk of electromagnetic interference. 827ec27edc
