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.

The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.
If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power.
High performance valve springs
The valves are like the doorways into the engine and control the flow of the intake air and fuel and then after combustion they control the exit of the exhaust gases.
As you can guess the valve springs work incredibly hard, and as you increase the power of your engine the valve choice is vital.
TorqueCars will now take a look at the many considerations taken into account when selecting valve springs.

Under bonnet temperatures are one of the biggest performance killers around.
Quite simply, you want your engine to be sucking in cold air as this carries more oxygen and will allow you to burn more fuel.
The exhaust system is one of the contributors to under bonnet temperatures. You can therefore lag the exhaust to help prevent this heat soak into the engine bay.
