A traction control system (also known as TC) is a system designed to prevent the loss of traction due to excessive throttle or steering. The traction control system is typically an electro-hydraulic system and is somewhat similar with the electronic stability control. However, these two systems do not have the same goal. To prevent the loss of traction, the TC can shut down one or more cylinders or reduce the fuel supply to them. It can also brake one or more wheels and can even close the throttle (in drive by wire cars). The traction control system commonly shares the brake actuator and the wheel speed sensors with the anti-lock braking (ABS) system.

A turbocharger is a forced induction compressor. The turbocharger is in fact driven by a turbine powered by the pressure of the engine exhaust gas. All turbochargers are made out of a compressor and a turbine. The turbine’s wheels rotate because of the pressure of the exhaust gases via the turbine’s inlet. The resulted rotation of the wheel drives the compressor which starts to compress air. Optionally, the compressed air can be delivered through an intercooler system to cool it down because hot air degrades the performance of the engine resulting in a loss of power. The air is pumped through the air intake of the engine and because of the high pressure, the cylinder receives more air. So the objective of the turbocharger is to increase the performance of the engine by increasing the quantity of air the cylinders receive. All this additional air that the cylinders receive requires an increase in the amount of fuel being pumped. This means that a turbocharged system will output from 15 to 40 percent more power at high rotations, but at the cost of fuel. The turbocharger has some security features like the wastegate. This wastegate protects the engine from receiving too much at air at high pressure preventing preignition or engine damages. This system works by sending some of the air away from the exhaust turbine and controls the shaft speed.

Car audio refers to the audio system fitted on a car. This can be stock audio or custom audio. The stock audio is the audio system specified by the manufacturer when the car was produced. The custom car audio can mean anything from changing the radio to installing state of the art audio systems.
