Wastegate control

This quite simply controls the flow of exhaust gasses and therefore the speed of the turbo and resultant boost pressure.

The speed at which the assembly spins is proportional to the pressure of the compressed air and total mass of air flow being moved. Since a turbo can spin to RPMs far beyond what is needed, or of what it is safely capable of, the speed must be controlled.

We will take an indepth look at turbos and see what the best way of tuning them is.
