water method kit

Does anyone run a water meth kit on their 6.0. Deciding on getting it but don't wanna cause any problems or much strain on parts that it can't handle. Any input would be great thanks.

Re: water method kit

The title is supposed to be water methane not method.

water/methanol injection can be used to lower intake air temperatures (think of it as 'chemical intercooling')...or as a power adder.

be warned that high(er) concentrations of methanol can cause significant engine damage.

for reliability reasons, *we* don't run any methanol...straight H2O

since a diesel doesn't have any spark plugs...the combustion/explosive event in the cylinders is controlled by fuel injection timing...

since methanol is a fuel...which would be aspirated through the intake valves into the cylinder...there is no way to control when the combustion of that fuel occurs...

you'd essentially be trapping a fuel (methanol) in the cylinder after the intake valve closed...then the piston traveling up to TDC is squeeeezing the volume of that cylinder @ 17:1...

if the methanol begins to light off before the piston reaches TDC...you'll have a serious spike of cylinder pressure even before the fuel injector fires...which can lead to bent/broken connecting rods.

(straight)water on the other hand is generally benign...as long as you don't begin injecting the water until 11-12psi of boost pressure.

injecting water into the engine at low boost levels may not allow the liquid water to evaporate (cooling the intake charge), and similar engine damage can occur (from increased compression ratio/water volume taking up physical space in the piston bowl/cylinder)

depending on your application (larger fuel injectors? towing, race/sled pulling), we have put together a very nice kit using Cooling Mist components.

Custom high pressure water injection - Swamps Diesel Performance

but on an otherwise 'stock' vehicle...water injection should probably be well down your list of upgrades.

If you do run W/Meth *I*'d recommend no more than 10% methanol, to keep things reliable. There are far safer ways to add power than increasing methanol %.

Re: water method kit

good info, thanks. I have run the Snow pre mixed stuff alone and -20* windshield washer fluid alone. do you know what the meth percentage is for the Snow pre mix and the -20 washer fluid? thanks.

I don't know...we don't run/recommend any methanol for the reasons above.

Re: water method kit

We run a 50/50 mixture and have seen no problems as yet. Have it set to come on at 12 psi. and use it strictly for towing on our 7.3. Have put on 20k miles so far. What concerns are there for long term engine wear?

Re: water method kit

I've had my kit on for about 20k and have been very pleased with it. There is both a noticeable bump in power as well as drop in egts depending on the % mix I'm running. My system is set to come on at 13 pounds of boost and I believe I'm running a 16gph nozzle but will have to double check. With just washer fluid (about 35% methanol) there is a small bump when it kicks on but egts climb much slower and will level out at about 1400 even with a load and at full throttle. (stock sticks, hot tune to both ficm and ecu, mtw stage 1 turbo) at a 50/50 mix there is a much bigger jump when it hits but of course much less of a drop in egts.
