opinions on water-methanol
 

I would like to know how my fellow bombers feel about water-methanol injection is it worth the price and is it something I should be interested in or would it just be a waste of money performance wise?

Been Running It For Years
 

I run W/M on both my Dodges and think it's a great bang for the buck. Adds power if you use 505/50 mix, keeps EGT in check on a highly fueled engine and also keeps the pistons and combustion chambers clean. But the kits are overpriced, IMHO. 1/4" tubing is $.25/ft. at Ace Hardware. Fittings are a few bucks apiece at McMaster Carr. Pumps are around $100 on eBay. You can cob up a homemade system for half the kit price using just a hobbes switch ($25) if you can find something cheap to use for a tank. The progressive controllers are nice, but not really needed except to support towing. I upgraded the '07 to a Coolingmist CMGS controller a few months ago. Very nice unit, but pricey.

CSIPSD has a kit on his 7.3... He loves it.. If you are looking for something to keep your EGT's under control then it's a great mod.

Yes it's great, if you don't use too much meth. I'd stay at a max of 30% meth 70% water. I am going to be be building my own kit as well. I plan to use mostly water, to aid in EGT's when towing and to keep the combustion chambers extra clean when running on WVO in my case.

I wouldn't really use meth as a power adder personally, it's an uncontrolled burn, and that is the opposite of what we're trying to achieve.

Make sure you are mixing methanol and purified water NOT windshield washer fluid.

I been running washer fluid + heet = 50/50 W/M for four years. :w2:

A guy on another forum did oil analysis and found lots of bad stuff in his oil after running washer fluid but it was gone when he would mix his own distilled water and methenal.

You Ever Run W/M?
 

Or you wanna hear about my oil analysis? Or maybe tell us exactly what "bad stuff" you are referring to? Maybe some details about the particular oil in question like the analysis regimen itself in terms of sampling intervals, trending, OCI, type of oil, filtration, fueling, and the specifics of the W/M system itself as it relates to the sized injectors, pump, flow rates, init rate/settings, etc, etc? How was the truck being used, racing, towing, daily driver, what?

Because without those details your warning is meaningless.

I agree, I'd like more details please! :c:

i'll see if I can find the thread. I didn't pay to much attention because i don't run it...

Thanks everyone and mdub with the 50/50 you say u wouldn't recommend it bc the uncontrolled burnwhat is the risk or negative affects of that?

I can't find the thread. It was a guy with a D-Max van on PSN.

Melting stuff? It will light and burn when the piston is already travelling back down the hole. It's uncontrolled because it's just not stable and you really have no way of controlling when it will ignite. This may be acceptable on an older mechanically injected vehicle, but we have very precise injection cycles and can control that, adding meth seems to just take away from that. I'm not saying it can't be used in small doses, but it is my belief that you can over-do it too easy. I am planning on running a kit, but mostly for the water benefits.

TheStepChild has a dmax van, and he constantly posts about his w/m setup. He has a thread about how he's run 150,000 miles on it with no issues so not sure this is the same guy...

Actually just found the link you're talking about. He is just saying to use DISTILLED WATER, not tap water... obviously.

Control - What a Concept
 

It's not combustible below a 50/50 mix ratio. Injection timing controls when combustion occurs, regardless of whether it's the newest commonrail or the oldest POS 12v on the road.

Higher ratios tend to add an advanced timing effect which should be taken into account. That is due to faster, more efficient burn, not because of any mysterious alcohol-induced instability.

Injection timing controls when it's put into the combustion chamber, but does it truly control when it's burned? It ws my understanding that the meth burned AFTER the diesel fuel, and often times it would lite as the piston was already traveling back down and just create excessive heat. Thus why I said small amounts. I am by no means an expert on this subject, and you clearly have more knowledge on it than I do. Thanks for the input.:c:

It's a "Catalyst"
 

Diesels combustion occurs from compression heat in the presence fuel - diesel fuel or variant, normally. Methanol does not act as a fuel until it reaches a high enough ratio to become flammable (at or above 50/50 approx.). Notice I said "flammable" not "combustible" there's a difference. Up until that point, the only thing it has to offer the fire on your piston is some extra oxygen molecules and more complete burn:

Just still curious about something I have not much knowledge about yet haha .... so if M/W is non combustible then what is the point of injecting it with the water or is that the only way it could work?

---AutoMerged DoublePost---

Well I have learned some thanks everyone but still have some questions. So if W/M is non combustible. Under a 50/50 mix then what is the methanol needed for water injection alone would cool your temp down wouldn't it? :pca1:

It's not "flammable" under 50/50. Did you read the document linked in my previous post?

Oh yes I understand now I use my phone and didn't go far enough to realize a second page had been started but thanks for the help. Much appreciated, your efforts werent in vain! :c:
