??? Methonal is alcohol. Look at the op 100% meth is gone over.

in the first post it says that methanol is a weak acid. i'm pretty sure methanol and all alcohols are very basic.

 

Yes but,

Just like a majority of all alky's, meth can act either acidic or basic in behavior. Its got a pKa of about 15, it will be a slightly weaker acid than water, yet it will still able to react with strong bases like hydrides, or with materials such as sodium metal. With meth it will attack the oxide coating that protects aluminium from corrosion. Therefore acting like an acid.

Again I'm trying to keeping it more basic and simple for the general public to understand.

this man has this thread to a science is this your own research?

 

Yes for the last 7 years I have had over 4 different Aquamist kits on my cars.

I am having trouble reconciling these two things. Which is better at cooling? The meth part refers to cooler intake air temps - does that translate into cooler in-cylinder temps?

Thanks!

 

Water has 2x's the latent heat value than methanol therefore removing 2x's more heat.

Methanol's viscosity at .59 and water at 1.02 its almost 2x's more easy to evaporate and atomize meth than H20. The process from going to a liquid state to a gas is when it removes the most amount of heat. Therefore water wont do as good of a job till its in the cylinder and is completely evaporated. Water injected at half the amount of meth will do a better job at cooling but it changes where the cooling is occurring either in the IC pipe or cylinder. Hence with a 50/50 mixture you get the best of both initially for most setups.

All this really depends on jet placement, and environment. Currently I am running over 840CC of 100% H20 on 87 octane with 2.0 Bar of boost from a GT35R HTA!! no knock and EGTS are below 800C

thank you, awesome article.....

 

Do the reduced EGTs with water come from running increased timing and leaner mixtures, or directly from the water? I'm setting up my HFS-5 and with 100% water I'm seeing no change in my EGTs with my usual pump gas tune. I've confirmed that it is spraying.

 

is there anything to purchase for 50/50.. or basically eye ball half a container with methanol and the rest with water? lol

 

My buddy never mix anything. He used denature alcohol from Home Depot.

This is what I use. I just add some to get to 25/75

 

denatured alcohol is roughly 50/50??

 

No. Denatured alcohol is essentially 100% alcohol, but ethanol rather than methanol.

 

Each setup is different. Depending on jet sizes, jet locations, climate and tuning methods will help effect egt's, mbt, ect ect.

100% H20 is a hard task with one jet as the distribution of it is a lot harder than with a 50% mix.
