Hello,
I was rummaging around on the internet and found this site:

Almost sounds like one of those cyclonic intake catalyst thingys. The science sounds like it will work nicely without many downsides, what could the downsides be?

There's nothing mystical and magical about methanol injection. There are probably a couple thousand diesel trucks in North America running one of these kits.

I've been running Snow's Stage 1 Diesel kit on my HDJ81 for a few months. It works. I would estimate that I gain 20% more power and definitely lower EGTs. Don't expect to see your EGTs drop by 200F when you flick the switch, but if you do some semi-controlled tests you will find that you can go faster up the same hills without an increase in EGTs.

If you're interested, I'm running the 225 ml/min nozzle with the pump regulator backed off 1/2 turn and that's the limit of what I can inject. I have mine set to come on at 5psi and max is set to 12psi (manual boost controller is set at 13psi). I only use it when I'm going up the big long highway hills that normally have me backing off the throttle because my EGTs are going through the roof. That, or if I want to gun it from a stoplight to get ahead of someone...

20% more power for $500 - how can you go wrong?
 
Adam B,
What are you using for your injection fluid. Some websites advocate using cheap windshield wiper fluid(no detergent), as an injectant. Wadda are you using?

I use 50/50 water/methanol. Once it's mixed it works out to about $5 per gallon.

Some time I'll try straight water to see what the difference is.

The cheap blue washer fluid (must be rate to at least -20 or it doesn't have enough methanol) is about $2 per gallon. It's supposed to be around 30% methanol. The thought of running blue die and detergent through the engine is a bit sketchy in my mind so I've only done it a few times. I wouldn't hesitate to do it on a trip if its the only thing available but not as a normal thing.
 
water injection?

Is this the same as pantonne systeme?
I looked in to this, but it is all a myth as far as I can see!
A friend tried with a camper and his mpg droped 20% so did the bhp!:confused:
 
Straight from Snow's website.....
_______________________________
Why Water/Methanol Injection?The Boost Cooler® is Snow Performance's latest generation water/methanol injection system. The primary function of water/methanol injection is to provide "chemical intercooling".


In gasoline engines, as with any intercooler, this suppresses detonation so more power producing boost and timing can be utilized. Water, with its high latent heat of vaporization cools the intake charge and combustion. Methanol cools the charge and combustion but also acts like an extremely high octane fuel (some researchers claim as high as 120 octane) as well as adding more oxygen to combustion.


In diesels, the effect is three fold: 1. The intercooling effect provides for more available air and all the benefits of a higher positive pressure ratio (more power giving fuel can be utilized safely without high combustion temperatures). 2. The combustion of water provides for more power on the power stroke. 3. Methanol acts as an additional fuel for more power.

A brief History:

Water injection was evaluated scientifically in the 1930.s by H. Ricardo who demonstrated that one can basically double the power output of an engine using water/methanol. The first widespread use was during WWII on supercharged and turbocharged aircraft. In 1942, the German Luftwaffe increased the horsepower of the Focke-Wulf 190D-9 fighter aircraft from 1776HP to 2240HP using 50/50% water/methanol injection. The allies soon followed by fitting the P51 Mustang and other high performance aircraft with water/methanol injection. Following the war, the turboprop aircraft industry used water/methanol injection and called it the "automatic power reserve system (APR)" for use in hot or high altitude take off. It surfaced again in the 60's when GM used a system on the OEM turbo Corvair. It was used effectively in Formula 1 before being banned for adding too much power.


The latest competitive use is in World Rally Racing (WRC) where virtually all teams use it in some form and in diesel truck/tractor pulling competition. It is important to note that in the fall of 2004, the long standing world record in the quarter mile for diesels was broken twice (now 7.98 sec) by two different vehicles; both using the Boost Cooler® water/methanol injection system by Snow Performance.

If you over-inject, you will misfire and end up with results like those. I have no idea what the effects on mileage are, since I don't run it continuously, but there's no question that my power gains are significant.
 
oh !

:doh:exuse my european ignorance,looks like some cool gear! Can it be used all the time? Not just when you need extra power.
 
Lots of people seem to use it all the time, but if you're going to do that you will be consuming lots of fluid and probably need to step it up to the Stage 3 kit (although I don't know if it works for low boost applications like ours). The Stage 1 and 2 kits inject based on boost level while the Stage 3 kit also monitors EGTs so it doesn't just max out the injection every time you're at max boost like mine does. If you're at max boost but only 800F it won't inject very much, but if you're at lower boost and higher EGT it might inject more. It's supposed to be much better for your consumption rate than my Stage 1 kit.

I can empty the little 1.5L reservoir they supply in about 15 minutes of 10-13psi driving up a long steep hill. From Vancouver to Kamloops I stop 2-3 times to refill the reservoir and I'm only using the meth on the big hills or when I need a sudden shot of power.

This was just a trial period for me, and now I'm convinced that it's a good thing so I'm going to convert my washer fluid reservoir so I'll immediately triple my capacity and free up some space under the hood again.

Compared to propane, I imagine this is cheaper and it's dead simple. I don't know much about the possible negative effects on a diesel but I haven't heard anyone on the meth forum talking about blown up engines like you hear of in the propane world...

now the question that begs to be asked is...can you run both PI and HM in the same engine at the same time??

Could be much . ?

We're tallking about the cost and relative simplicity of the system. I said "I imagine that this is cheaper and it's dead simple". Is a propane setup cheaper or easier?

from wha ti have read in your poist and from what i already posted (if you actually read all of it) the initial set up is a bit more expensive for propane ($300) but the end cost is more. of course if you want a tank under the vehicle then the cost of the propane is quite a bit more...

Downs are; Lifting the heads or blowing a gasket with to much water/meth mix.

Simple: one of the biggest advantages I see in water/meth is that any idiot can install it safely on their diesel. There's no tuning required, it's practically bolt-on and go
