Engine/Transmission (1998.5 - 2002) Water/Methanol injection

[monkeyman]

I just intstalled about 300 miles ago a Snow Performance water injection/methanol. I have the Banks High Ram intake mainifold which I taped for the jet.

I mounted the pump under the front bumper on my Sport.

I mounted a six gallon water tank in my bed as it uses alot.

Winshield Washer fluid is 50% Methanol and water and a little food coloring so its cheap. Here is what I found out. After fine tuning and having injection start at about 19-21 lbs boost. I found exhaust temps down about 200 degrees. Performance up about 15% or more. You can feel the kick. Less smoke, seems to be smoother.

Did tests from start to 90-MPH. I think for the money you can't loose. Contact Matt at :www.snowperformance.net He returns...s of puting a Diesel section on his Web Site.

Windshield Washer fluid is 50% Methanol and water



Don't think 50/50 is correct, all the MSDS sheets I've found on windshield washer fluid is 25-30% Methanol, I like the 6 gal tank though, I use the windshield washer tank.



Matt's system is nice and can flow large amounts of water, 200 degrees is about right for EGT reduction but I haven't tried more water yet, nice system and I really like the nozzles.

Six Gallon tank

In my business we use the same fittings that Matt supplies (Jaco)

So ibought a six gallon water tank from Pep Boys ($10. 00)

Put a Jaco Fitting on bottom, starpped it to my LP tank. And ran line along frame. You can see the liquid level through the tank. I turned down the pressure on the pump so the amount of water would be less.

Could someone explain to me how this works?



$300 for 100 HP is REAL cheap, considering that the average going rate per 10Hp is $100.

 

[HillCountrykid]

To get any hp gains with water injection, you need to be putting more fuel in the motor that it can burn. One benefit of water inj. helps burn the extra fuel. But unless your seriously overfueled, you won't see big gains. A lot of people run water to reduce egt's.

It's actually real easy, it cools the air (water alone) going into the motor and when you add the methanol it cools better but adds BTU's (fuel) for more power.



Some things I will talk about openly on the internet and some I won't remember this thread https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=77501&highlight=694/1179



Some things I will talk about, I started the deal on my truck about 5 months ago and noticed some big gains in power and big drops in EGT's but I was having to shoot allot of water to get the effect, so while talking to Matt at www.snowperformance.net we both agreed that his nozzles were much better than the ones I was using so a changed over to his setup and noticed immediate gains looking at lower air intake temps and the same EGT reduction with 1/2 the water of the old system.



If you do your homework on the TDR you'll remember when I ran 12. 70@113. 8 with my stock pump and everyone was wondering how I made so much power out of a stock pump (Custom plate, Laser DV's and 4K's with 370 injectors) The fact of the matter was I was running 13. 10's@107 on straight fuel and ran a best of 12. 70@113. 8 with the old set up, so what did it make on the dyno 60hp/90 ftlbs back to back runs. That's about all the info I'll put out right now but it give you the idea of the affect, and one last tid bit on the dyno runs I dropped 70 degrees of air temp at the hat with the old setup.

HMMMMM me tinks this might be good for heavy haulin

I'll give it a go & see how it does

$300 not too bad, that could be a night @ The Red Rock West Saloon in NYC

Jim,

Which water setup do you suggest for street truck in the 500hp area?

Which setup are you running?



--Justin

 

[Jim Fulmer]

Justin, I would go with the big pump and two nozzles, I run a pump like Matt's but his pulls less amps than mine and I turn mine on via hobbs switch at 30 psi of boost, Matt's setup turns it on at low amp... slow pump speed at lower boost then on full later as boost get's higher this type of setup is good for both us and towing, if I were to use it towing I would just shoot straight water but that's me. Right now I run (2) 675ml nozzles but just made provisions to run 3 nozzles to see if it does any better.



This setup is probably the best you can do for the money and I feel like this is one of those (everybody is going to have one things) by next year. Any data that I have or will get Matt will have it as the Diesel thing was new to him just a few months ago, now I have him really interested in it, he said he has sold allot of kits for cars over the last few years.

nozzle location

Jim, where is it recommended to inject the methanol/water?



I have thought about a system like this to cool the incoming air and I was thinking about injecting it between the primary and seconday turbo to help cool the air before it goes through the intercooler.



I guess there is a chance that the intercooler will cause the vapour to turn back into liquid before it hits the engine.



Where have you got your nozzles located.





Thanks

[Jim Fulmer]

4 questions here so I will answer them in numbers.



1. In the manifold is what I have heard is the best but I don't do that.



2. I did the between stages and don't see a problem with it (it eats at the turbo blades though) but I never saw a greater reduction at the intake hat... . that is were it counts.



3. I ran water before the intercooler for a long time with no adverse effects



4. I had one in the pipe to the hat and one in the hat before, now I have both in the hat and have the other hole with a plug in it and will try that R&D and try another nozzle in the pipe later for a total of (3) and see what the gains (hp) and losses(EGT's) are like.

Water

Thanks Jim, appreciate the great info.

Jim

Is this the same guy that was at the LSTDR rally last year?

It seems like a good solution to EGT problems.

John

 

[Jim Fulmer]

Nope John this is a different system, the auqumist systems are nice but they don't have the same flow capablility, those systems seem to work fine on small cars were you don't need allot of water.

Jim,

I've not used water injection but have heard that it puts a strain on the head gasket, especially if you are running stock compression. The thought being that even small water droplets are not compressable so in affect, increase compression. Any truth to that? Larry

 

[Jim Fulmer]

Funny you mentioned that Larry, guess what I was doing when I took out the stock gasket... . racing/winning with water/meth on full board, the compression thing could very well do it and the 63 psi at say 500 hp could have done it too I like the new setup better though as it atomizes the water very well, once I get back to the dyno I'll do more testing and report the results.
