How turbo and supercharge works?

First of all, I read somewhere and they said it is impossible to make your car faster by simply installing a new chip. Well it can make it slightly faster but you wont be able to notice it. In order to make it faster, you need the engine to produce more POWER.

In order to burn more fuel, the engine needs more air (oxygen). No point putting in more fuel if the ratio is not right because not all of the fuel injected into the piston will be burnt. This result of wasting petrol and may damage your catalytic converter.

Simply taking air from inside is not enough because hot air does not contain enough oxygen.

There are three ways to increase air supply into your engine:

1. Turbo charge -common in Japanese cars (there is lag because it needs energy from the engine to work)

2. Super charge-common in American cars and useful for drag because there is no lag.

3. Nitro- temporary only

Another method to make your car faster is engine tunning. This means replacing the engine parts, making air easier to flow. However this is only for racing purposes because it makes your engine sound very loud...
