I found a web site that has plans to make a steam injection system. They say that steam injection works better than water injection because the steam condenses into smaller droplets when it mixes with the air stream and the extra heat helps to vaporize the gasoline.

I don't consider their plan to be ideal. It uses vacuum to draw in the steam so it wouldn't work under full throttle. I think it would be best to have the system vary the water flow rate according to the fuel flow.

Here is the web site with the plan:
Better Gas Mileage with improved energy efficiency by water injection.

Here is one about water injection that includes some test results:
Water Injection By Robert Mann

Mother Earth News had an article about using an emission control air pump to power a water injection system.
WATER INJECTION WIZARDRY

Wikipedia has another article about water injection. It include links to some more web sites.
