Anyone ever tried water injection

[racing]

im wondering if anyone has ever tried water injection to keep the motor cool under high stress and heat like what sled pulling tractors use to keep there motors cool.

just wondering if anyone has tried it

I used a water injection system in my rally-race car. It was a turbocharged eagle talon. Basically, the water would spray the intercooler, thus cooling the air even more. Worked really well. However, I was running close to 6000 rpm for extended periods of time.



No reason it shouldn't work for a truck.

I know that was an early first genners trick for not having an intercooler, the trucks would get pretty hot. Some would just spray on the rad to keep it cool.



J-eh

I used water injection on my 99 Powerstroke.

Works great to lower egt's and gives a definite boost in power. I used to mix about a cup of methanol to a gallon of distilled water and the water injection was set up to spray into the turbo inlet.

That sounds interesting, can we build somthing like that ourselves or where do you go to get it. I would like to play around with that.

I used the stock washer pump with a manual floor switch(button) installed.

You need a coupla' feet of washer hose, a "horn" switch, some wire, and a washer nozzle.

I sprayed right into the inlet of the turbo.

It DEFINETELY worked. Felt about the same as a 50hp chip and lowered EGT's significantly when the motor was being really worked. I really liked it and would recommend it to any turbo diesel owner.

Aquamist sells a system for about $500. They have a high pressure pump that atomises the water better. It is also boost sensitive. You could try the window washer bottle method too with some form of boost switch.

ok now that we know it works it is on to the next question has anyone used water with an intercooler? what i am wondering is if u spray it right into the turbo inlet then would it condense in the intercooler and cause droplets to form (real bad thing) or would it stay a vapor/mist after being cooled by the intercooler

 

[Kentand]

May recommendations from racers are to spray just before it enters the intake manifold to maintain maximum misting effect other wise it may condense into larger droplets which is bad.

Check out "aquamist"'s website.

If the link works, go to it. We discussed this in depth a while back. This should aswer your questions.

That's a no-no...

I race a turbo car and have seen the consequences of this system. While spraying into the compressor inlet may decrease EGTs, it also wears the crap out of your compressor wheel. The compressor wheel is made of aluminum and the friction will wear the blades.



Food for thought,

that's why I wouldn't spray around the turbo. Also, with higher pressure sqyuirters, it is just higher humidity, not droplets.
