water/ meth injection
 

ok so i was looking at the Diesel Stage 3 MPG-MAX™ Boost Cooler 5.9L Cummins for my 91 dodge intercooled and pretty much stock, my first question is will it work in my truck or am i just totally looking for the wrong thing? second is how hard is the install on one of these? ive never done one or even seen one? and third is is it really worth it? i have no egt gauge now and it has one built into the system so i really like that but will it really be worth the money and time?:tu::td::argh:

I have the Snow stage 3 kit not hard to install at all. It's basically mounting the tank, pump, running wires and drilling a few holes. 3 in your intake horn and one in your exhaust manifold. 2 holes are for injector nozzles 1 is for the boost you will need to tap all 3, easily done with horn off the truck. When you drill the manifold have the engine running this helps with shavings and don't center your hole or you will hit the divider plenum. Also the increases are immediately noticeable in power especially with a 49% meth mix and I gain 1-2 mpg on just water. :jump:

thanks and i will probably take out the maifold and turbo when i decide to install it because that seems a little safer to me i would rather just buy some new gaskets and do it that way the risk anything, and thats so sick to get better fuel milage with just water lol
:jump::rocking:

Yeah and drops egt's too! :tu:

ok so i got to thinking about this last night and was wondering how it works? where does the power come from? and how much does it cost to fill the tank/how often do you have to fill it? thanks. tanner:argh:

The water mist cools the incoming air like an intercooler does and colder air= more power. On the cost to fill it that's kinda up to you Snows boost juice is pricey 6 bucks a gallon from summit racing, but you can mix your own way cheaper. Just got to find a place that sales racing fuels they will have methanol it's around 3 bucks a gallon here and mix no more than 49% meth to 51% water and that makes it about 1.50 a gallon. You can also run -20 washer fluid just make sure it uses methanol. Wally world stuff works fine. From what I have noticed you get a little bump from just water 25-30 hp all the way to 70+ hp on 49% mix. :jump:

Oh and on how often you have to fill it depends on on how you have it set you can either suck it down or seemingly run forever on a tank I leave mine set for egt's I tow alot but you can set it to spray at boost levels as low as 12-15 pounds this drains it because its just to fun! a 7 gallon tank should last couple hundred miles once the new wears off

ok, and that will work with the intercooled 91 cummins with stock injectors and i wont be burning anything up?

There's nothing to burn. In actuality, you could increase your fuel because the colder air coming in will allow for it.

haha thats awsome these are just questions my dad is asking me about it before he will let me order it lol:argh: now its time for that and some bigger sticks/ over sized injector lines and ill be set lol that will be plenty of power for me thanks guys
Tanner:jump:

Skip the over-sized injection lines ~ waste of money. ;)

x2.

hey guys have you ever thought of buying a 55 gallon drum of methonol? if i calculated right it comes out to 17.7 full tanks in the 7 gallon tank that comes in the snow max kit shouldent that be about a years worth? and that is $3.09 a gallon for strait meth does that sound reasonable?:humm:

You just have to keep it clean and don't let any trash in it. Just be sure to go no more than 49% meth to a gallon and your good to go for around 1.55 a gallon. Oh and DON'T SMOKE AROUND IT!!!!!! :scare2:

Where do you get 49%? Just curious.

I run a 50/50% mix all the time. I've read of some folks running up to 70% meth but I expect they most likely have issues with pre-ignition.

It's been my experience that a 50/50% mix is relatively non-flammable (I've tried burning a mist of it. It only made my lighter wet).

:pca1:

Just in people I have talked to with the cummins you don't want to hit the flammable mark when your grid heater can come on. That would be bad:ouch: so just erring on the side of caution don't want a fellow 1st gen going down in flames

Mmm.... Water injected over long periods of low-load operation. :yum:

Is that a oil/water mix and where did that come from? Mine has never done any thing like that

I can do that at will on mine. Somehow it never happens to anybody else. I must be doing something special, can't figure it out though.

the 55 gallon drum if 98%meth but then i mix it with water to get my 49% 51% right? and ill proly go a little leener because i dont want to harm my truck, how do you know when the grid heater is on? and none in my family smokes and they are the only ones who will know where it is :tu:

Yeah you mix it with plain water. The heater cycles on and off in cool to cold weather and to know when it working just watch your voltage gauge lol

well that would work exept im to cheap to go buy a capacitor for my sterio so my voltage meter is always fluxuating when the sterio is cranked(all the time)

Begle, are you still making chocolate milkshakes in your crankcase? :s:

The more water I inject, the more milkshake I make. Still does it, happens on low pressure or high pressure, high load or low load. It all goes away after a couple hundred miles without water.


It may be exceptional atomization on top of worn engine, or just a worn engine. Blowby isn't visible except after an exceptionally hard run. Never tried using standard water injection nozzles. Then again, I'm also still fighting low coolant temperatures. Even with a new Cummins thermostat, open freeway driving with below 80 degree ambient temperatures never cause ECT's above 170 measured from the freeze plug on top of the thermostat housing. I don't know what my oil temps are, but it's feasible that they are typically below boiling, so I can't boil water out as well as other people that run at 180 coolant temperatures.

I have no doubt that any water injection system does put more water into the oil than you would have otherwise. But water is a major emission out of any engine, and water gets into the oil on any engine; usually oil gets hot enough to boil it off as it comes in. I still don't like the idea of water injected at low loads over long times though; even if you can't see it, you're watering down your oil. If you have oil analyses saying that it keeps looking good and your pH and viscosity aren't moving around, then I'm grudgingly okay with it. Sure doesn't work for me though.

thats crazy that your oil looks like really light mud! what water meth kit are you using? cus i dont want to do that with mine thanks for the heads up with that cus i want the stage three mpg max kit whitch injects at low boost levels also and if thats gunna happen ill find annother kit -tanner

Or it might just be too much water - too many / too big nozzles.

More is not always better. :nope:

You also mentioned something about "light load?" If you are injecting water below around 15psi that would also translate to too much too soon.

Below 15 PSI is what the "MPG Max" kits are designed to do. No matter how much I inject at low boost levels, I get milkshake. Those particular pictures were after about, oh, 6 minutes of injection above 15 PSI and 1100 degrees EGT; the prolonged low boost injection milkshake had extra whipped cream on top.

My system is totally custom.

Sounds like your system is totally wrong I start injecting at 5psi somtimes with no such results like your having you may want to rethink your custom system Is this straight water or mixed

I have doubts about the efficacy of injecting water at low load for MPG purposes.
