Water is effectively infinite octane. It can never detonate. If there is too much water then there will be a slight reduction in power, but that would be more water than would be reasonably used in an injection kit like this.
Alcohol does reduce the tendancy to knock, primarily because of it's cooling properties on the incoming air, but also because it has octane. Octane cools and slows the flame travel, thus reducing the instance of pre-ignition.
On one hand water and alcohol do the same function, it's just that a small amount of water is more effective at quelling detonation than a large amount of alcohol, while alcohol, on the other hand is more effective at adding fuel. If your fuel system is up to the task, there is no real reason to use alcohol, IMO. What you're really after is to be sure that high compression, coupled with low octane pump gas, doesn't get detonation started.
That said, I use alcohol in the mix because I think it's effective at offsetting any minute power loss associated with too much water (as added safety). Also covers over any bad pump gas.

If the fuel system is up to the task I would think you could get away with just water. You would just have a lower ceiling for power. BUT it would still be very reliable at that lower level I would think.

Guys, I thought the same . . . that you could use just straight water. I have not dyno tested these theories yet, but I'm leaning towards 100% alky nonetheless . . . maybe if I have tons of time I will dyno test both approaches.

Click on link below. Click "car album". Click "water/alky" on the left hand side.

I'm thinking about taking that Idea and going a step further. Since we have such a large and oddly shaped windshield washer resevior anyways, why not cut it in half, and use one side for H2O/alky and the other for WW fluid?

have been talking with Steve on the phone several times. I think he and I have come up with a pretty slick design very close to what jrios has. I'm really happy cause the last thing I want to do is clutter up an already tight engine bay. I'll post pics when I get them.
But so far Steve has been great to deal with. very willing to go the extra mile for the business.
