When putting more power through an engine you need to ensure that every part will perform at its optimum.
One of the motorsports favourite techniques to improve the durability of an engine is a process know as cryogenic treatments.
As you can guess from the use of the word Cryo – it involves the cooling and heating of the engine block to temper the metal changing its structure.

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.
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.
