h20 injection is not mainly used to reduce intake temp but to prevent detonation. A small amount of vaporised h2o in the combustion chamber will prevent a nonsparkplug arc from creating combustion (preventing knock). Water in the quantity of 30% of the fuel that is being injected is what is recommended and has been known to be beneficial. Any more or less reduces the benefit. By just adding water does not improve horsepower, you have to either advance timing or increase boost.
Brad is the expert in H2O injection for saabs though. So maybe he can help you.
