I'm going to do something similiar for my tt setup and am wondering how long the water lasts.. my car will be street driven btw. I'm assuming you only inject under boost? how big of a cell do you have for the water/alcohol (or whatever) mix?

 

i'm useing my windshield washer resivor and it lasts around 2 tanks of fuel.mine only injects at full throttle.

I'm running a 5 quart container from a shifter kart, haven't really run out, top off now & then when checking oil & looking around under the hood. Mine injects whenever boost is at 3 psi with a specified pulse width and the pw increases as boost increases.

 

excellent..thats what I wanted to know.
