The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (the efficiency of the engine at drawing in air) although forced induction is the most effective method of upping compression.
In computer games we just tick a box, and within seconds our car is fully turbocharged and running much faster. In the real world things are very different.

Power gains from a sports catalyst
Catalysts are a vital component in our modern tree hugging environmentally conscious society. First TorqueCars will look at what a catalyst does and how it works.
A catalyst is actually a term used to explain anything which accelerates or performs a chemical reaction. In a car the exhaust fumes are fed through a matrix of ceramic honeycomb lined with precious metals.
Blow off valves, dump valves and screamer pipes
Blow off valves and dump valves.
When the throttle is closed (when you lift off the accelerator) in a turbo driven engine there is a build up of pressure as forced air is still coming from the turbo. Lifting off the throttle is a lot like putting a plug in the sink – the flow through is stopped and water would just build up and overflow the sink.
