...true, you "boost" the HP by using super- or turbo-charging, but the water injection is there ONLY to keep the engine from "detonating" instead of "combusting."

...anybody remember the turbo'd Olds engines of the 1960's that had a separate little bottle of GM Turbo-water (H2O+ethanol)?
Back before intercoolers, knock sensors, and computers...
These days most people go to a mechanic to fill there windshield washer fluid, filling up turbo water is too much to ask of your customer.
