Competition Water Mist Injection on 400-500HP?

[Morepower]

It was raining today and noticed how much lower my exhaust temp was with the extra humidity. Is anyone out there using water injection combined with NOS and Propane during competition?

Frank, you coming to San Antonio for the drags?

Nowel,

A better question is, Are you coming?

If it were my truck... . I would be careful when using NOS and water injection simultaneously.



Chunks of ice cant be good for making HP or hard parts longevity... .

If you use water make sure it is distilled water. Tap water has deposits and chemicals that are not good for the turbo

There was a guy at the Kerrville Rally that had and Aquamist system set up on display, real nice equipment! We were talking about injection water right after the intercooler so the cooler does as much as possible, but the system only puts out 300 ML worth of liquid per Min, I need much more than that to cool the charge.

Jim,

How many ml were you looking for on your truck if 300ml is not enough?

 

[Jim Fulmer]

Heck I don't know, I guess any amount would be better than none, that's a coke can it a min, how about 3 times that much. If the system had the capability of pumping that much that would be cool then you can test, I can only imagine what my air temps are!

Hello Jim,



So how much water do you need? The 1. 0mm jet can flow 350ml/min. You can also run multiple jets off of one pump. Granted if you run two 1. 0mm jets you total flow will be more like 600mm/min instead of 700ml/min. If that is not enough you can stage multiple pumps off of one trigger.

What's up Shane, I haven't forgot you! It I could run a system with two jets on one pump then that might be ok, I'm not looking for Nitrous type cooling just want to drop the intake air charge, I don't like the idea of fly by night windshield washer pumps, that's what was so nice about your setup, it's high class stuff. I'll stay up with you, I have some cool ideas for installing it.

I want to stay drug free..... for now at least!

If I am using a 1. 0mm water jet, what mixture of distilled water to ??? would you use? Especially if you want to keep it from freezing in the winter.



Under 40lbs of boost and stage 1 nitrous kit with a . 055 jet, is it safe to use water injection? I would think under pressure that the air in the intake manifold is still above freezing water. Especially if it has been mixed with some additive to keep it from freezing in the winter. What do you think?

 

[Deezul1]

Mixing alcohol with the water will help keep it from freezing, dont know effect on Diesels of this combo but it worked great on my gasser and a mix should deliver a little more power than straight water. I used 50/50 on 11. 5 to 1 compression motor that I was stupid enough to think I could use for a tow vehicle also. The water injection was the only thing that helped that sorry combo.

 

[CTHOMAS]

The 50/50 mix helps a lot if you are dumping a lot of fuel,but don't have the boost to burn it. I guess a little like NOS. It can real keep the egt's down also in most cases.

Water Injection?

Is there any long term problems?



A lot of years ago this was popular with gassers; until some of the longtime users found that there was a LOT of crude in the lifter area (of a v-8), which was the result of WATER IN THE OIL . That caused mine to fall in the garbage can pronto. Just something to think about. The ctd is different, but...

Re: Water Injection?

The avgas airplane engines and turbine engines used a mixture of H2O and Methanol, about 60% H2O and 40% Methanol. The H20 added density to the the air charge and methanol added more fuel. In a diesel I would be concerned about what the mixture does to the combustion properties of the diesel fuel. To much water and you might have poor combustion and to much methanol or other fuel might have a major impact on the combustion properties, such as a very bad premature ignition.

60/40 at 1qt/40sec is a kick in the pants

methyl alcohol would be a better alternative. you can get it at a local drag strip or FS dealer. (the later being cheaper) water or alky injection is kinda like NOS it will just shut you down when you get too much you can run water, methyl or even Peroxide or rubbing alky they will vary in performance but will all cool EGTs.



a Hobbs (boost pressure) switch activated system is what i ran and had very good luck with it. you will want a high PSI (mine was a 220PSI i got from nothern tool, thanks Gonzo) pump to assure a good atomization and to not back feed the system. plus a good jet. I used the Gas (wet) jet from an NOS setup. i had it plumbed in the intake horn (elbow before intake on engine) on the bottom side out of view from inquiring eyes. a few guys run a boost fed system that uses the boost to pressurize the tank and pump the water out without a pump on it.



it will take a few EGT's off but what is nice, is you can enjoy a good 1 to 8 minute run(tank size vary), as apposed to a 15 second run before EGT's get out of hand.



OORRRR use it for pulling hills with the 5er and use AAALLLL your power to top it, instead of progressively backing out of it towards the top

 

[your mom]

Which will give the best performance and which will give the best egt reduction? What were the egts before and after?

 

[Morepower]

My New Aquamist system is shipped out and will be here in a couple of days. 220psi pump and a selection of jets. Thanks for the mixture tip of 60%H2O and 40% Methanol alcohol. I will find a fuel supply shop and buy what I need. It is nice to know that adding too much won't hurt anything. I like the Idea of instead of 15 Seconds of max power to 1-8 minutes and added performance with a cleaner burn. It should like cheap insurances running water so not to over heat the engine. What's next? Just when I thought I was done fooling around with upgrades. I guess it will never really end. Next is a set of good traction bars. I have my eye on RCD Stainless set. They are still not available for a Dodge yet and will have to check back in January. Cumming's Motors Rule!
