An intercooler is effectively a radiator that allows the intake air charge to cool down before reaching the engine It is sometimes known as a charge air cooler, is an air-to-air or air-to-liquid heat exchange component used on turbocharged engines. It increases engine output through processes that allow more air and fuel to be combusted per engine cycle, increasing the power delivered by the turbocharger to the engine and making it more efficient.
The cylinder head is the metal casing which covers the engine. It seals the main cylinders of the engine and prevents oil and other substances from finding their way inside. It also contains a number of valves vital to the engine. Internally the cylinder head has passages called ports for the fuel / air mixture to travel to the inlet valves from the intake manifold, for exhaust gases to travel from the exhaust valves to the exhaust manifold and for antifreeze to cool the head and engine.
A turbocharger is a kind of supercharger for car engines. It is in essence a gas compressor that increases the density of air entering the engine to create more power. The turbocharger is a clever design innovation in that it is driven by the engine's own exhaust gases. The turbocharger usually sits on the front of the main engine block and has its own chamber in which the gasses are compressed. Because of the immense pressures and strains placed on turbochargers, it is important to only fit high quality turbochargers to your car.
It's your gearbox that enables the transfer of energy from your energy to the road surface through your wheels.
Gearboxes allow torque or transmission, produced by the car's engine, to optimise the engine speed for the road speed
It's vital that your engine operates at a proper working temperature. Car engines can get extremely hot and quickly suffer serious damage as a consequence.
Usually located at the front or side of the car behind the fan belt, it's the job of the water pump to squirt water from the radiator to the engine in order to regulate its temperature. Centrifugal force then forces water into the engine block on into the cylinder heads before draining back into the radiator ready to be recycled through the system
