hello....interesting subject....seems it was used(and maybe still by some) for 2 reasons what i have gathered(anyone with more knowledge can add and please do)-1 was to increase CR since water -when compressed makes steam-steam takes of space-so in a cylinder this can create more cylinder pressure so after the spark there is a BIGGER bang for more power....another reason was to add to turbo engines(maybe supercharged also) to help control detonation and preignition.....basically using water will increase power....if anyone else has anything here ,please share- i have always wondered why this water injection isnt on every engine out there---mmm must be to simple to be good huh? LOL
