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.

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:

"The latent heat of evaporation of methanol is less then water. This basically means that less energy is required for methanol to go from liquid to gas state compared to water. During the compression stroke, as cylinder temperatures go up from compression, the methanol particles release from the water particles as they go from liquid to gas state. Once in gas state and at higher temperatures the methanol particles will ignite. This creates multiple combustion points distributed in the cylinder resulting in a more complete air to fuel 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?

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:
