There is a lot to be said for alcohol hybrid fuel systems ( which is what an alcohol injection system is ) but I feel there is still a lot of performance still on the table with simple water injection.

It was demonstrated 50-60 years ago that with an optimized tune, you can double engine power output with just water and methanol. Running straight methanol on the other hand is only able to deliver about a 15% increase in power before you get back into detonation / pre-ignition territory. The problem is, that current engine managment systems are not very friendly to the type of changes you need to make to get to the high power outputs with WI and still provide a fail safe tune if the WI fails.
