Turbos and superchargers can run extra boost with a water/alcohol injection system as well. That is to make lots more power, again no improvement in fuel economy.

But if it makes more power.....than it's more efficient.....so it gets better mileage!!!!
It's just like when you put vortex generators on a wing of an airplane......it gets more lift.....so it flies faster with less power and gets better mileage too....so that's why we put Vortex Generators on cars.
