Refering to the loss of power due to the increase in exhaust pressure by
adding a turbo charger on your car. 
I believe that you have to look where you try to get the energy from.
As much as I remember my thermodynamics class (oh what a nightmare) it isn't
so much the pressure of the exhaust gasses as it is the combination of
pressure and the TEMPERATURE difference between what you have after it leaves
the engine and what you have outside. Hot exhaust gasses still have alot
of energy in them, which usually goes to waste. Turbo chargers try to use
some of this energy to press more air/fuel stuff in you combustion chambers.
Correct me if I am wrong.
