Actually, water injection just boosts octane by scavanging the free radicals. It does work (I put one on a Corvette years ago.) It doesn't directly produce more power but it would allow a higher compression ratio which does produce more power with greater efficiency. (Unfortunately, it also raises the oxides of nitrogen to an illegal level.)

Is it hard on the engine?

......."Actually, water injection just boosts octane"......

I don't think water has octane. It does, however, cool the cylinder, which alows a leaner mixture without ping. It also adds power by the steam formed. If your car pings, (unusual today with knock sensors), You might try a cooler thermostat, say 160 deg.

Actually the old water injection was first used on planes in WWII. Next the large diesel's used to power train's and other stationary generator's run about 850 RPM, consider that the piston's in one of these weigh's about 55lbs each. And to the other poster there never has been nor will there ever be a 100 mile to the gal carb like the old legend say's. Think air to fuel ratio and you will understand.
