I'm going to do something silly here and assume you mean a water-methanol mix sprayed into the inlet manifold?

If so, go go go!

Do it do it do it do it do it!

It's like inter-cooling for an N/A engine. In-cylinder temps go down, wind in more advance, power goes up.

Who in the hell doesn't want MORE POWER?!?  ;D

Edit: Are you running forced induction? If so DO IT DO IT DO IT DO IT DO IT!!  :D

Just don't run out of water in the middle of the dunes is all. Only real negative.

Level gauge with a low warning light for the two gallon mix tank should solve that problem.

On steeps and such the tank needs to be very well designed also to prevent any possibility of the pump sucking air also.

It's pretty much just a smaller fuel tank. Make it tall and skinny, with the outlet at the bottom (of course!).

After a good talk with the dyno shop who tuned the motor I have decided to go back to avgas. I know I know.... we had a whole thread about it but worst case is I blow up a $500 long block. The motor was tuned for it and it ran on it for 3 seasons before I owned it. The price is MUCH cheaper than race fuel and its unleaded. $11.50/gal for unleaded race fuel or $3.50/gal for unleaded avgas. So if you boil it down:
-The motor was set up for avgas
-Dont need to spend extra for a water methanol system
-Dont need to spend anything to retune and upgrade for E85
-And fuel cost goes down
 
Either the water/methanol or the e85 conversion will cost more than $500 without a question. I might have no issues with the avgas for free. Seems like a no brainer to me.

17 LB of boost! Wow what kind of HP you running with that?  Who is your tuner and what ignition are you running? I would love to run stright avgas.  I can buy it all day long at the Dead Cow Airport in wichita.

AvGas is low lead, not no lead. So if your goal is to not get busted, you may still have an issue. A pilot told me when he pulls the spark plugs on his plane that face down, poppy seed sized lead balls fall out.

The Dead Cow is one of the oldest landing fields in the Wichita area.  It is right down town. If your driving on Pawnee Ave and a plane comes in for a landing your going to have wheel marks on top of your roof.  It will only except small air craft. No jets.  That's where the old twin engine airforce one came from they towed up to the Yard Store.
