The turbo will increase the amount of work that is required to expel
exhaust gasses. You know those MPG gains we get from running
free-flowing exhausts? Reverse that when you put the turbo impeller
in the exhaust stream. It's not *as much* of a drag as the
supercharger, but you cannot get higher pressure in the intake
manifold at zero cost, unless you have a solar-powered electric
supercharger.
