Default Methanol mixing question

Ok,

I'm sorry if this has been covered at all and I did try searching the forums but I couldn't find the answer.

When I mix methanol and water, does there need to be a emulsifier need to be used? Will the meth and water seperate? also, I know to mix by density, so what final density will i be looking for for a 60/40 mix? Basically you need 1.27 times as much meth as water right?

so 1 gallon of meth to .79 gals of water would be good for a 50/50 so 1.1 gals of meth to .711 gals of water is 60/40?

just worried about water seperating thats most of it. thanks for the help anyone

Yeah Im very curious about the need for emulsifier too
so can anyone who mixes their own water and meth
chime in????

Thanks

Okay nvm well according to Methanol Wiki
water and meth are miscible
and will mix

OP - why are you concerned about density? I think you're being a little cerebral here: just mix it 50/50 (60/40, whatever) by volume and be done with it - that's what the rest of us do. And, yes, meth and water are 100% miscible, no "emulsifier" required.

Oh, btw..."boostjuice" is simply 50-50 with a colorant added. Mix your own and save big $$$.

cause volume mixing is wrong when densities are involved. Not the same amount of material, thats like taking a cubic inch of gold and a cubic inch of aluminum, mixing them and calling it 50/50 its not. thanks for the info on miscible or not

ok this is a valid point: however, I'm pretty sure your tuner isn't a chemist, and I'd warrant a guess that the guys making the "boost Juice" aren't either. while I don't know, I think its pretty safe to assume that 50/50 means by VOLUME. you can probably check with the folks who manufacture boost juice, but my guess is that they wouldn't know specific gravity if it jumped up and bit them in the @$$...
having said that:
specific gravity of water = 1
specific gravity of methanol = .792

if you make a mix that is 50/50 water/meth by volume, you will create a mix that is 45/55 water/meth by weight. This 5% increase in meth concentration will increase the octane of your mix slightly, and increase the corrosiveness and flamability of the solution very slightly. Since many people run mixes as strong as 30/70 water/meth, I think 45/55 is pretty safe.

Thank you. Let's leave the high school chemistry class out of this before this discussion denigrates into one about molarity, for goodness sakes. Boostjuice is a 50/50 volume mix, as are all the other mixes, period.

If you mix it, that is what matters. Mix it 1 gallon of each, and then get tuned for it. Or mix is 1.2858809547892893 galons to 1 gallon and get it tuned. Whatevr you do, just make sure you do it the same way next time, Your car doesn't know the difference of volume and weight, just the AFR.
