just wanting to increase my knowledge/curiosity. What exactly is is and how does it help or increase power?

Water injection has a couple different ways that it can be presented. In any case the idea is that you inject or spray a fine mist of water either pre-turbo or post-turbo into the intake air where the water mixes with the air before going into the comobustion chamber. The added water effectively lowers your EGT's when the engine is burning so much fuel that the EGT's can't be controlled. Mostly used in tractor pulling for heavily fueled engines. <br><br> Most people inject the water post-turbo using a high-pressure pump with a fine misting nozzle and a water tank in the bed of the truck. Others who inject pre-turbo have the added security of the turbo it's self mixing the water/air charge. Downside is that if you don't carefully do this you'll end up eating the blades away on the compressor with the droplets of water. Another, cheaper, way to do water injection, (if your not in serious need of a LOT of water in a professional situation this is) is to run a water tank in the bed, run a copper line under your truck, and wrap the copper line around your exhaust pipe, the heat transfer from the exhuast to the copper line will turn the water to steam and the steam will go up through the copper tubing where you'd have it plumbed into the intake either pre-or post turbo. The second way of doing it is the cheapest obviously and uses a lot less water. Using a high pressure pump uses a lot of water and is mostly needed for those who are running so much fuel that they need a reliable source of water as to not damage their engine. Hope this helped.

to put it short- I don't need it unless I am heavily modified and can afford to change my motor and or turbo frequently. 8)

You got it.

Water is not like Propane where it's an alturnitive fuel. If used at the right times, and in the right ways, it can have VERY good results. <br><br>The idea is to &quot;kill the fire, but leave the burn&quot; in the combustion chamber. It works great for drag trucks also. <br><br><br>Andrew
