Engine/Transmission (1998.5 - 2002) What about water mist systems?

[Morepower]

I noticed how much cooler my exhaust temps were when it is raining and extra high humidity and then started thinking about what if I was to add a water mist system. Do people use them in competition during tractor pulls and drag racing or to clime a big hill with a heavy load?

 

[Steve St.Laurent]

I have heard of them being used for sled pulling. Wouldn't work for drag racing though - the track officials would not appreciate you wetting down the track! Most tracks use VHT (a liquid that's sprayed on the track) to help with traction and it becomes slicker than snot when wet. Another fopaw many people make at the track is running their air conditioner (shame shame) and dripping water on the launch area.

 

[jkern]

it is also about power...

water injection in diesels is not new, alot of sled pulling tractors and trucks use it. its use is two fold, mostly for added power and then cooling. when you inject water into the combustion chamber the detonation of the fuel charge and subsequent "explosion" turns the water into steam. i don't know the actual numbers, but a very small amount of water will make a exponetally huge amount of steam. the steam then acts just like the fuel charge, expanding as a gas creating even higher combustion pressures than the fuel alone thus more force on the piston which we all know equals more power. a by product is actuall cooling because the steam will carry heat away and then condense back into water.

 

[JWhitcomb]

Are we talking about water injection internaly or spraying the radiator? Years ago I made a spray system for the radiator and it worked well and recently I saw an ad for a setup that does the same.

 

[Morepower]

I was talking about after Turbo water mist in the tube before the intake manifold. It sound like what I would be looking for. Under full power you could pull down the 1400-1600 exhaust temp range a couple hundred degrees and keep from melting pistons for a little longer.

Check out Aquamist,

I am currently installing the S1 on my truck now.

Jerry,

Where did you go to buy your Aquamist System 1S kit?

I checked out the website and it didn't make any mention on dealers in the USA.

It looks like the website is in the UK.

How much did you pay?

Ivan

 

[Rob Thomas]

Ditto, I would like to know also Jerry.



Later, Rob

Aqua Mist System

Found a site in USA. the S1 system is $425. 00

Here is BKA's e-mail ,he answered me :AquamistBKA@aol.com

Great!

I have another thread that someone posted to check into "POWERSNORTER" but have not been able to find any thing on this unit.

Benifits listed by http://www.duramax.bizhosting.com/My_Truck/water_injection.htm

Key Benefits

Reduces IAT [Intake Air Temperatures]

Improves power output of engine

Improves fuel economy

Reduces combustion chamber deposits

Helps keeps engine oil cleaner

Easy install using common tools

OEM [original equipment manufacturer] quality and compatible weather resistant connectors.

OEM style wire loom, looks like a factory setup.

Hi-pressure system uses a pump not turbo boost, this ensures proper 'spray pattern' which is easy on the turbo blades and mixes with air better.

Unlike boost pressure powered systems, water will not continue to inject in the case of a solenoid failure, in fact only the second stage of our 'dual stage' system uses a solenoid, but that is after the pump, so if the solenoid fails open you will only get full water injection at boost pressure when the engine is running only and maybe waste some water.

Industrial grade and quality hi-pressure pump

Long lasting pump, [not a cheap windshield washer pump]

Pump can run-dry, but not recommended.

Optional tank with low water level indicator

Optional tank for various applications

Optional tanks are not steel and will not rust

Optional filter to keep nozzles cleaner.

Dual-stage system avaialble for additional cooling.

First stage for most benefits

Second stage for added benefits at higher boost levels and loads, such as when towing or going up hills.

This kit designed is specifically for the GM 6. 5L Turbo Diesel.

Other kits available for other vehicle / engine applications.

MADE IN THE USA.

Single stage kits from Only $4XX. XX without tank

I found this website a while ago, this system sprays water on the outside of the intercooler, pretty neat. http://www.autospeed.com/A_0827/page1.html?src=suggestions

do it your self!

Hey, I did this and it was only about 100 bucks. I tried to lower the trans temps in my 98 auto by installing a mister system on the trans cooler then added sprayers to cool the intake system too. It is easy! No need to spend 4 c-notes on this. You need a water supply, 12v power, a pump and hose and misters.



Tank: Used rv supplier, 26 gal $40

Pump: Used rv supplier, sureflo demand $20

Mister hose: Home depot, $20

Drip irrigation sprayers 180 degree pattern: Home depot, $3

Misc hose and fittings: Home Dept, $20

Switch: Auto parts store, $3



Mounted tank on plywood in the bed with pump attatched to wood, plummed to tank. Put in a "T" at pump with shut-off valves(drip irrigation stuff) installed garden hose fitting on one side of "T" so I can run a hose to fill the Trailer, the other side of the "T" went to the engine compartment with flex hose then connected to the mister hose. The misters that come with the hose are worthless for cooling. I added drip irrigation sprayers (180 degree pattern) by pre drilling the hose and screwing in the sprayers. So very easy... You might want to add a shut off valve under the cab so you can reach it and stop the radiator shower when you want only the hose in the bed to work. I've used the hose with a nozzle to clean fish, deer, elk, wash the truck, feed a portable sink, ect... I'll try to post some pics if I can find them.

If memory serves me, the expansion rate of steam is 1600/1.

I set up a water injection system a couple of summers ago and it works!!!! It does drop EGTs and seemed to add more power. I had it spraying water preturbo.



Here is some of what I learned...



With water injection you better have a working waste gate. With all that expanding steam boost climbs super fast right to the waste gate setting. I ran it only once with a non gated 16 CM2 housing and at 3/4 throttle and 20 PSI turning the water on shot the boost to 45PSI I never had the guts to try it at full throttle.



You need a big tank, it goes through alot of water. Any of you that know Aston hill out of Idaho Falls heading to Wst Yellow Stone, I ran a 1/2 gallon container dry about 3/4 s of the way up it pulling my TT. The neat thing was I was able to maintain speed and had actually backed out of the throttle some and my EGTs dropped almost 200 deg.



The first time I used it there was major black smoke. It cleans the combustion chamber right out.



To much water can be really bad. Hydro-Lock:--)



Good luck and keep us all informed... .

first impressions

I can see a significant drop in EGT (200+-)

cant get over 1350 deg.

much quicker spool up.

HP/TQ, some gain

not sure how much yet.



there is a guy in bastrop TX,. His name is Shane Lowrance

P. M. me for a phone #

He is giving the TDR members a good price brake. He mainly worked with gassers until about three weeks ago. I took him for a ride in a 7500# lead sled and changed his whole outlook on diesels. crawling out of the truck the only word I under stood was (damn!)

I am Sold and now can't wait to try it out. The Aquamist S1 kit website information had the best explanation and resource information. I have a heavy 40' fifth wheel and DDIII injectors and am looking for extra insurance to climb long inclines. It sounds like a cool solution. I am surprised how few threads on the subject and seams like a untapped source of extra safety margin on EGT with added benefits.

Jerry how many other systems did you look into before you decided?

NXS, is this guys system post turbo?

I looked at two or three different systems. the systems that use a windshield washer pump seemed a little week. I don't know how they can atomize the water properly to get a good uniform vapor pattern



Patriot



the answer to your question is post intercooler.

pre turbo is not good. Over time it will cause erosion on your compressor wheel. pre intercooler, can make the water vapor condense in the intercooler as the compressed air is cooled.
