More meth means you get the fuel but not the cooling side of things...
So with a more even distribution with an emphasis on meth you get the higher octane, with the benefits of a cooler charge at the same time!

meth does not cool AS MUCH as water does... water is the most cost efficiant way and safe thing you can spray into ur motor and make it cool the best... water= best cooling for the money... alky and meth i beleave are still a liquid form which will help the blower cool down to if i am not mistaken but i beleave he is saying meth bumps up ur octain and water is more for the cooling( considering its easier to cool with water than meth/ alky).

Blueberry, whether or not methanol burns cooler then gasoline doesn't explain why the blower is cooled by the methanol injection.
Since it burns in the combustion chamber, and not the blower that would not explain why the blower is so much cooler with methanol injection.
The methanol flashes off in the blower, and that is what causes the temperature drop. So you get cooling and octane booster from methanol.
Why does it seem that the fastest people out there that use alcohol injection are running anywhere from 70% to 100% methanol, and not a 50/50 or 60/40?
You simply make more power with a higher methanol content.

Oh, and it sounds like you are claiming that water burns blueberry..

Oh for godssake....
::FACEPALM::
And I was one of those "FASTER" ones running 60/40 and as you go higher... you get more fuel allowing for more timing.
Do some research

you cant compare times because there are tones of diffrent facters... First off why would u want to do 100% meth when its proven that water is more helpfull in cooling over methanol?? Any awncer and if u need help Google meth / alky injection. ive used meth injection plenty of times on my Grandnational So i think i know what i am doing also... not saying ur rong but i did get to advance my timing but my ait did happen to get hotter which inturn made me loose t/q in my midrange and topend hp was also lost.. if i can find some dyno charts ile get them up ASAP but i am almost sure that i made the best with like 75-25( 75 Meth, 25% watter). might be diffrent for my GN but thats how it worked out 4 me..
Also just to clarify : the car was cooled down after every run
The temps never changed( outside)
Same day same dyno
idk my elivation( idk if that matter or not)

I agree with you, it takes experimenting but you make your best power somewhere between 70 and 100% meth.
At 50/50 or 60/40 you put too much water in, and limit the octane boost you are getting from the methanol.
I didn't ask for his 1/4 times, I asked for his trap speeds on an m62, preferably a non ported m62 on a stock engine, then I can give him a better comparison.
There are still many variables in trap speeds, but a lot less then in the 1/4 times, which have huge variances.
Kevin
I was trying 100% meth because my temperatures weren't that high, so I really didn't need to maximize the cooling, as I found it worked better to maximize my octane, and run higher timing.
I am going to do some experimenting with a larger nozzle, and an 80/20 meth water mix and see if that does any better.
