i was actually looking at this one https://www.coolingmist.com/pagedisp...ure_key=diesel
not cheap though, i guess non of the store bought ones are.

 

Can you say DISAPPOINTED?

Made it to the track last night and ran an 18sec 1/4 mile at about 75mhp.

The good news is my EGT's at the end of the track were just approaching 1200! I have no long flat roads near my house to test my truck after I make tuning adjustments, so I always test it going up the same highway hill. Guess the fuel screw really has some room to be turned in, assuming I can then keep my foot out of it on hills. I also need to drop some excess weight like a topper/mattress frame, huge wood sliding thing built under mattress frame by PO, about 100lbs of chain I had back there, and an overbuilt plow mount on the front. All of this crap has to account for a good 500-1,000lbs of weight.

Smokin92: It was nice to meet you there last night. I really hope you weren't watching when I ran though. What did your buddies truck run?

 

It was nice to meet you to. I did watch the run, but you and i know that you could have run faster than that. His truck ran a 17.9 the first run and by his third run he ran a 16.7. His only mod is a zero fuel plate.

 

In my opinion the cooling mist system is better, not to say it really is but i like it better. They do claim a 300 degree drop, backed up on a dyno, so if egt are your only concern that alone is nuff reason.

 

So now that you have had water/meth for a bit, what do you like about it?

what don't you like about it?

How much water/meth dus it consume?

at what boost dus your system come on?

What kind of mix are you using?

 

I haven't really tested it yet enough to give solid feedback. To give you an idea, I've only gone through a 1/2 tank of water/meth and the tank is only 2qts.

I like the fact I could turn my fuel screw in another full turn and only gain 100* max EGT's. The EGT's seem to creep up slower under WOT than they did before too. I definitely didn't notice a massive 200* drop, but then again I was only maxing out at 1300* when I installed it. Someone who is seeing 1500* before install might actually notice a 200* drop. Overall, it seems like adding more fuel doesn't make the EGT's skyrocket like it did before.

I don't like the fact it's hard to tell when it's on. I installed an LED next to my boost gauge which comes on when the pump runs. I have another LED on the other side of the boost gauge which is for the clogged nozzle detector. The detector seems kind of inconsistent in it's operation. Sometimes it blinks when the system 1st kicks in, then turns solid. Other times it goes solid when the system kicks in, but then goes out after a second or two. Supposedly this is normal operation and it will stay lit after the system kicks off if you have a clog (it hasn't done this yet so seems to work). Oh, I also don't like the fact I'm injecting gallons of water with a 150psi pump into my Cummins...but I'll get over that eventually.

Seems to consume relatively large amounts under long WOT runs. I just haven't been able to test it enough to burn through a tank though. I could easily fill up the 2qt tank and drive to the track, take 3-4 runs, and drive home without refilling.

The system comes on at 18psi and maxes out at 30psi. The great thing about the controller is you can adjust those numbers on the fly though. You can also use the preset 10 position "Tune" **** to lower or raise the overall psi of the pump...all on the fly!

Still using the 75%/25% water/meth mix. My max boost is up to 34-35psi and my gauge goes to 35psi, so I'm trying to limit it to 35 (I know...I need a WG now and fricken Bill was right again ). I think a 50/50 mix would put my boost around 38-40psi and I would rather not go that high since this is a tow rig afterall.

Anyway, I'll post a new thread after a good long test. I want to do some towing with the system too and will let you know how that goes.

 

Bill, you gotta add that to your signature.

 

Well I reckon I'll be able to let you know in a week.

 

Where is this homemade version posted at??

I have been looking, but not finding.

Also, how do you feel that your set-up is going to bring down the EGT when towing heavy??

I am going to do one, or the other, soon, as I am getting tired of backing off on account of the pyro going through the roof.

Thanks.

 

Here's a link to the awesome thread by Loch: Link

I had a chance to tow my rockcrawler (5k total) for a couple hours yesterday and played with the controller a little. It seemed to drop EGT's a good 100* while climbing hills. I tried running with it off and then turning it on while pulling a hill and you could hear the extra power and boost (not too mention feel it) when the system kicked in. All this while the EGT's dropped steadily from 1100* - 1000* (pre-turbo).

Keep in mind I still only have 1 nozzle and 2 are definitely needed on our trucks. I have some extra ones sitting here that Coolingmist was nice enough to send me and plan to add a 2nd one in tomorrow. This should provide additional power and reduced EGT's I assume.

 

So dus this mean that you are glad that you when this route!?

 

Absolutely!

I hope to be even happier after I get the 2nd nozzle in tomorrow.

 

so how does the cooling mist story end anyway? I still dont see many people running that kit. I was told by snow that the nozzles for the cooling mist was a sprinkler nozzle? who knows probably just as good. its just water

 

I run the Coolingmist VARI-COOL system and am quite happy with it. Performs as expected.


"Sprinkler Nozzles?" Hardly. I've a smaller nozzle that I replaced with a larger and have taken it apart. High quality filter screen, finely machined gyrator plug thingy (imparts spin to the fluid) with equal quality nozzle orifice.

Sounds like your Snowboy is just bad-mouthing the competition.

 

I am running the Snow Stage II with a Stage III controller. You can switch the controller to work on boost only or for boost and EGTs. I have not towed with it yet but you can see it working if you leave it in the boost/EGT mode. The controller will show the W/M injection % based on these parameters. For normal driving I leave it in the Power setting which works on boost only. The controller shows EGTs, boost and % of injection. After tuning it on a dyno I have the adjustment dial set at 100%. RWHP increase with this setting was 100 RWHP using a 50/50 mix of W/M.
