RAM Air Induction
Ram air device can also provide forced induction. When the car is travelling in speed, air will be forced into the engine manifold through the ram air inlet which usually locates on the top of bonnet. That create a slightly higher pressure than normal aspiration.
In fact, you can see ram air devices whenever you watch motor racing. The air box in every formula 1 race cars and the roof air inlet of GT race cars are all ram air devices. A Formula 1 engineer said a typical air box can gain 20 horse power when the car is running at 200 kph.
