Let's look under the hood
Need for Speed is now showing on U-verse Movies. To get you pumped, check out some of the key components that make cars go fast. Click on the buttons for more info.
A supercharger is essentially an air pump that compresses an engine's airflow before it actually enters the engine. By adding more air, the engine can mix in more fuel, which results in more power. On average, a supercharger delivers a boost between 30% and 50% over the car's original output.
A turbocharger boosts an engine's horsepower. But instead of compressing an engine's airflow like a supercharger, it compresses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine spins at speeds of up to 150,000 revolutions per minute (rpm) — about 30 times faster than most car engines can go.
A cold air intake is an aftermarket assembly of parts used to bring cool air into a car's engine. Cold air intakes move the air filter outside of the engine compartment so cooler air can be sucked into the engine. The result? It allows the engine to breathe and offers a significant power boost.
The distributor is found in the ignition system of an internal combustion engine. It's a device that routes high voltage in the correct firing order to the spark plugs. Still following? Adding a high-performance aftermarket electronic distributor delivers impressive torque gains and a smoother idle.
A pulley is a wheel mounted to the engine that guides or drives a belt. This belt is part of a system that powers peripheral devices within the engine compartment, such as the air conditioner, power steering, and fan. High-performance undersized pulleys turn these components more slowly than standard-sized pulleys and use less power from the engine. The freed-up power allows you to drive slightly faster than before with improved fuel economy.
