A turbo or supercharger acts as an air pump which allows the engine to put out it’s rated horsepower through different atmospheric conditions. A turbo is exhaust gasses driven and a supercharger is driven by the engine.

The turbo provides additional boost from the exhaust at higher rpms. The super charger provides additional boost at lower rpms. The intercooler makes your fuel to air ratio denser and richer! Most young drivers have no idea what sub components do on their own vehicles, yet they drive them and sometimes pay for them!

a turbo increases the speed of intake air into your engine. more air can burn more fuel. so for every intake stroke of a piston in your engine, a turbo puts more air in that it normally does, and your car can be set up to put in more fuel along with it. this in turn makes more power. The turbo does this by tapping into your exhaust to turn the turbine. as air moves faster and is compressed, it gets hotter. intercoolers take the air from the turbo and puts it through a radiator like device and tries to take some of this heat off. the octane rating on fuel dictates the fuel’s ability to withstand knocking. if air is too hot, you will need higher and higher octane to keep the engine from knocking. intercoolers help you generate more power without knocking. there is more, but you didn’t ask for a book.

Any engine needs 2 things to run and make power. Air and Fuel. A turbo charger is basically 2 fan blades connected with a housing for each blade. The exhaust side has exhaust gases pushed through it by the engine, its only job is to turn the intake or compressor side of the turbo, the intake side draws air in from outside the vehicle and compresses it, so that more air can be forced into the engine, allowing the engine to make quite a bit more power than it normally would. As you can imagine the exhaust gases heat the turbo up and this causes the incoming air to be heated as well. Hot air is unstable and will allow detonation before the air/fuel mixture reaches the combustion chamber, this is where intercoolers come in. The compressed air from the turbo is sent through an intercooler ( which works like a radiator would) bringing the intake air temp down to eliminate detonation.

Difficult to explain in detail because it is very involved. It is sort of like Jet engine theory (if you know how it works)
It takes exhaust pressure, spin a large wheel. The wheel is shaped like a cylinder, one side is wheel (pushed by exhaust pressure) and the other side is inside of a compressor to build up pressure. If that pressure builds up to a specific level, the air is pushed into the engine. That is why it is called forced induction. You are burning more gas, air (hopefully cold air, which compresses better) in confined space. that is how you are getting additional power because you are getting bigger bang out of each engine cylinder.
Because the turbine bearing uses the engine oil, and compressor heats up and contribute to the engine heat, you need some way of cooling the oil to keep the engine at a normal operating temperature. That is why you use intercooler. Basic idea is get the hot oil from the turbo process, run it through the radiator like fins to cool the oil and circulate back into the oil pan.
