2. Forced Induction System
Turbocharger
Turbo’s send compress air flow into the engine
More air in the cylinder will also increase fuel in the cylinder, thus giving more power from each explosion in each cylinder.
Typical boost provided is around 6 to 8 PSI, but then again you can boost higher around 10 or more.

3. How Turbo Charger Works
Ambient Air goes into the compressor wheel
Then flows down to the Intercooler where it becomes Cold
Then flows into the engine cylinder
Turns into hot exhaust gas and goes into the turbine wheel
It was then released to exhaust and waste gate

4. Most Powerful Turbocharger
For a 2-stroke engine
Low noise level
Compressor Ratio: 4.2
Efficiency: 70%
Compact Construction
Outputs: 20,000 to 25,000 kW per turbocharger

5. Fastest Production Car
Bugatti Veyron 16.4
0-62: 2.5 Seconds
Top speed: 253 mph
Cost: 1.1 Million Euro
Veyron Engine
W16 Engine: 16 Cylinders
4 Turbochargers
Power: 1001 HP (736 kW)

6. Turbocharged Motorcycle
Turbocharged are mainly used for cars but can be put on motorcycles.
The constant noise you hear after each gear shift is because the waste gate is being opened and closed.
