the part I find interesting is how the idea of water injection has once again come round to become a objective cure.
I remember back in the `70s when people were force feeding this crap and blowing up engines left and right. the only thing I can say the water does effectively is remove carbon deposits on the combustion chambers and pistons.
its negative effects are little more of a concern.
cast pistons can't deal with the incresed flex of the domes for long before they fail from fatigue. the other fine atribute of water in fuel is noted as "putting out the fire". the catylist will actually suffer on the long term because it can't make heat effectively. it will plug up and cost you more then any amount you saved. so fair warning on the "benifits of water injection".
