make sure to use 100 octane or you will probably pre-detonate.. and make sure not to put too much water in there because if it wont compress you might bend a rod.
edit: if you do the water injection :banana:

The amount of water injected is about 10-20% of the amount of fuel. No liquids compress and since there is a minimum of 5 times more fuel in the cylinder it will bend the rod first. 
Seriously though most don't understand water injection is not taking a hose and sticking it in the throttle body wide open. The amount of water injected to the total induction charge of air and fuel is only 1-2%. I know that small amount seems to provide a lot of benefit - but it really isn't that much in the scheme of things. There is significantly more water in the cylinder after combustion from the steam byproduct of burning gasoline than most would ever inject.
