Water Injection
Haven't seen much on the site about using just plain water injection on our 6.0"s. I was thinking about the possibility of a simple spray injection system with a nozzle just ahead of the turbo. It would need a boost sensing system to turn on the pump only when the boost is at a high level. Water injection has been very effective in the gas powered system and was also used in turbojet engines many years back. It should be effective in reducing the temp of both the compressed air from the turbo and likely the egt's and just as a side might clean the compressor side of the turbo a bit. Any Thoughts???

My primary idea is to simply use the water injection (no methanol) as a charge cooling agent. Most of the systems I see via the net use very high pressure injection and are very expensive. My thought would be a simple spray / atomizing head mounted maybe just behind the air filter. As that is on the low pressure side it should not be necessary to use such high pressure pumps to inject with. A simple pressure switch attached to the boost side of the turbo (a tee in the boost gauge line should work) that would turn on a simple 12volt pump when boost pressure was above 10 or 15 psi. The water mist would then go through the compressor side of the turbo thus helping clean that area as well. Anybody tried something like this?? I seem to remember something like this was sold a long time ago for gas engines and had the nozzle mounted in the air cleaner cover spraying directly into the carb.

Using straight water to keeps temps down is great. 6.0's don't like meth.
Introducing it ahead of the turbo isn't the best idea. Even water will wear on the compressor wheel. In the intake elbow, or CAC tube leading to it, is the best spot for your nozzle(s)..
If you're going to make some kind of system yourself, make sure you have safeguards in place. I've read about guys trying to make things work and hydro'ing their motors. Then they realize their attempt wasn't foolproof and the cylinders got filled with water overnight.

experence states that when all 8 rods are bent at the same angle and the customer has a blank look on his face when you ask how the meth was.... it a priceless moment.

They are just being cranky and want to get shafted.
You know it is a real blank look when it is crystal meth.

Our set up was mounted to the carb up stream of turbo we used small jet and vacuum pulled the water and fuel at the same time no pump and it was controlled by the amount of boost. We used distilled water and only ran it for 30 sec from start to finish no problems with the turbo this way. Bike ran low 8 sec in 1/4 mile. still have that set up in the basement. Only held a pint of water.

With the ccv junk going through the turbo would not a minor spray of water help to keep some of that gunk from building up on the turbo? Yes I know a reroute would be the best but haven't gotten to that point yet and the idea of a reduction in the egt during towing and under heavy boost seems like a good one. Important part is to insure safeguards against excessive water flow and make damn sure you could never hydro the engine. Some sort of small venturi in the upstream intake area that would create enough draw to pull water through a nozzle might be just right. It will make a good research project.

Also, if you place the nozzle ahead of the turbo, it'll be ahead of the intercooler. The temp drop across the cooler and large surface area make for a perfect place to gather all of your water, without any benefit. Water is typically injected at ambient temp, so you rely on a pump and nozzle to make the finest mist possible, so that it is suspended in the intake charge, and disperses evenly . The closer you can keep it to the intake valves, the better.
If you're going to try and make a kit yourself, do more research with the kits already out there. Experimentation can be very expensive..
