buy a liter of 100 proof vodka. lol

from the sounds of things, i think you should run something close to what a stock wrx would use (im not sure on this), youre not far off from one. The only thing to consider is the more dense air coming from the fmic.

50/50 seems to be the most popular for a number of reasons. It’s definitely the easiest to mix (dump 1gal denatured alcohol and 1gal distilled water into a 2gal container, shake well). 50/50 is also not flammable to direct flame. This is good if you’re storing it under the hood in your washer bottle. If you have another storage method (i.e. trunk or solid enclosure such as a fuel cell) then I would definitely run pure alcohol. You’ll see larger gains if you can safely store it. Obviously whichever blend you choose you’ll have to be tuned for it and stick with it.

70/30? still flammable?, i got the smc kit and it uses the stock washer bottle so yes it will be under the hood...

what type of alcohol, i was told it can be purchased at home depot, or use windshield washer fluid?

I use 1 gallon of denatured alcohol with 2 gallons of water. Works great for me.

Ethanol (Denatured Alcohol) is by far the easiest to obtain. You can buy it by the gallon at any paint store (i.e. Depot, Lowes, etc) its known use is for paint stripping and will clearly say “Denatured Alcohol” across the can, plus you can drink it (read: shine)

Methanol is the toxic grain alcohol (no drinkie or die). From what I understand Methanol can provide better gains then Ethanol, but it’s much harder to source.

It’s been said that at 50/50 mix of Ethanol and distilled water, combined with 93 octane pump gas, is the equivalent of 108 octane race fuel at full spray.

Are you trying to get someone killed ??
It is denatured that means it is poisoned by the addition of methanol or some other chemical precisely so it cannot be drunk. Otherwise you'd have to pay liquor taxes on it!!

PLEASE everyone do not even THINK of drinking this stuff

I was speaking generally of the difference between the two alcohols. One being the poisonous wood alcohol methanol, and the other grain alcohol ethanol. Distilled Ethanol in its pure form is otherwise known as “shine” and commonly available (depending on which state you live in ). As hotrod mentioned, Denatured alcohol is Ethanol with added adulterants that make it useless for consumption as an intoxicating beverage by rendering it toxic or extremely distasteful to drink.

Bottom line: Don’t drink either… Sorry to confuse…

www.powermist.com They're in Newton, NJ - they'll sell to you directly. You can get pure methanol or methanol blended with MTBE which will still cool your charge like pure meth but delivers higher BTU's. I think it runs around $35 for 5 gallons of their HoleShot Methanol (MTBE).

Methanol or ethanol are fine. Denatured methanol can be found at any hardware store for aqbout 10-12 bucks/gallon.
Also, the alky's injected to cool the charge temp...not for combustion.
You can use straight water (I did for a while) but you have to tune for it...more boost, bigger timing, that's what it gets you.

I have it on a stock turbo and it made a tremendous difference.

it will help since you can lean it out and add more timing.

Huh?

The Alcohol is used for far more then just cooling the charge. Yes it provides chemical cooling but Ethanol is also an oxygenating fuel, meaning it adds oxygen to the fuel mixture so that it burns more completely requiring less atmospheric oxygen, just like Nitromethane. This is why combined with pump fuel the octane characteristics of the mix are increased allowing one to tune for leaner (less pump fuel) and continue to run safely. You’re simply substituting a portion of the pump fuel injected, with the alcohol which combusts cleaner, cooler, and more completely.

while we're on the subject, anyone ever cut their alchy not with distilled water but rather with hydrogen peroxide?

more o2 = more betterer (providing you fuel it)

The only problem with that is finding H2O2 in a high enough concentration. Most of the stuff sold in stores is only 2-3% H2O2.
Also light breaks down H2O2 so storage can be a problem.
