It was perhaps inevitable with the increasing numbers of small forced induction petrol engines appearing that this old technology would re-surface. Water Injection
We have all experienced how engines run better in dense humid air conditions so this may be a good thing. Claims for performance improvement and better mpg's may of course depend on where the comparisons are made when ambient humidity and altitude may influence gains made. i.e owners normally driving at high altitude and dry conditions are likely to experience better gains than others. Some might argue its just another engine "subsystem" to go wrong- while inlet manifold injection may be OK I don't like the sound of their fuel water metered emulsion system!!
