Who's running it? And does it really lower egt's substantially? Oh, and what about performance gains? Thanks

I installed a Snow Performance kit for a fellow who tows a 16,000 lb trailer with a '97.
Running straight minus 40F washer fluid lowers his egts 150 - 200° on the hills.
He wasn't looking for more power so I can't comment on that, but he doesn't have to downshift as much.
Best bet is to talk with Snow, if that's the system you are looking at, and tell him what you are after. He will match the nozzle sizes and pressures to match your goals.

Performance gain is in my sig. The pyro was pegged at 1600 degrees on the straight diesel run, water/meth dropped it to 1400 degrees. That was on 50/50 mix.

Thanks for the info. Yes, I was looking into "Snows" kit that they offer. As of right now, I have more power than I can utilize. I am blowing a little too much smoke while towing 10,000 lbs and egt's are higher than i would like. I was told that this kit would lower as much as 300 degrees and add about an additional 90lbs of torque. Also i'm thinking that these injectors might be a little much. Would a comp box help this? or do i need to start looking for other turbo options?

For towing, Snow's stage 3, in cab adjustable, regulator is the only way to go. A 6 to 7 gallon tank with windshield washer fluid, the pump set at 250 lb max psi, and 1 625 jet will do the job quite nicely. You can expect at least a 200* drop in egts, if you're not seriously over fueled, a small gain in power, and very smooth water delivery with this system.

Something to note is that methanol is a fuel and requires air to burn and creates more heat when it does. The water counters the heat produced by the methanol burning. If you are already significantly under-turbo'd, you may not see results as good as others are seeing. Some severely under-turbo'd people have reported an EGT rise verses a drop. However, if EGTs are your sole reason for using it, running straight water will lower EGTs no matter what. Just won't get much of a power gain out of it.

OK, that's all fine, but how do you get him on the phone? I've called 6 times and have yet to get anyone, at all. I have the smaller kit, but wanted a larger one. Now what?

Bart Timothy

That's a good question. Snow's been in the process of moving. Maybe it it will be a little better now.

One more thing to consider is that you should not use the water/meth as a band aid fix for a turbine housing that is far too small for your application. Your stock HY35 only has a 9cm housing and it is over fueled with an EZ and Jammer 3's.....trying to tow with that combo is only magnifying the problem.......while the water/meth will lower your egt, you may not find much of a power gain as the result of having excessive drive pressures because of the tiny housing.....more power and mileage could be had with a 12cm or even a 14cm HX35......then the water/meth will really help with power too.

I agree with AKRam/CTDNut. Your EGT problems are from your HY-35 and you won't be able to consume enough H2O/Meth to solve it.

I love mine, but I'm only running slightly over fueled. I have started running 25% Meth...so I can inject more, and earlier. Minor power increase and 200-300* drop when heavy in the mountains

I have the Stage 2, with 2 #625 nozzles. I start injecting about 18 psi boost.

The snow's system is a must, IMO for heavy towing with added HP, and a big aid for hauling heavy in the mountains... but at WOT, for me anyway, it slows the climb to 1500* EGT's but does not prevent it.

All info appreciated. I am suffering bottom end power while towing. Top end is great. At this point though, I was looking for a quick/cheap fix for the excessive heat problems I am ecountering. I was looking into going with twins for the bottom end fix. However, if a HX 35 is adequate/cheaper, then i might look into that route. Thanks again.

turbo thom

You don't need twins. Just install an S-300 and away you will go.

Are there any precautions to be aware of with water injection?

RowJ

I don't know that the Injection system will do much for you low end problems.
Precautions?
1-Take a lot of testing time to get it set up right for individual needs....not a plug & play BOMB!
2-Must allow for 5 min running time, after using the injection system, to clean out the cylinders in order to prevent oxidation/rusting.
3-Bringing in the injection at too low a boost setting will cause rough running and/or quenching of the combustion.
4-Using a lot or too much Meth can elevate cylinder pressures very quickly...it is a hot burning fuel. 50% or less appears to be ok. No problems at all with winterized washer fluid (20% Methanol, I believe).
