BORGWARNER NEW TURBOCHARGER BMW N47C16 2011-

A turbocharger is a device fitted to a vehicle’s engine & is made up of two halves joined together by a shaft.

On one side, hot exhaust gasses spin the turbine that is connected to another turbine which sucks air in & compresses it into the engine. This compression is what gives the engine the extra power & efficiency because as more air can go in the combustion chamber, more fuel can be added for more power.

A wastegate is a valve in between the exhaust intake and the turbocharger bypassing the turbine to control the boost pressure.

To reduce the temperature a secondary radiator, or intercooler, intercepts the air before it reaches the engine.
