Use of Water/methanol injection

OK, so I have read a lot on water methanol injection uses in stuff like carb spacers and other places like that. I tried searching on SNS for a thread with any users and came up with little to speak of.

It seams like it would be a great way to make some instant power and all. Does anyone have any experience with it? I have some friends that have wondered about it as well but none of us know anyone who has ever sprayed in their cars.

Basically I'd just like to know more about it. Stuff like:
Power gains, applications, installation, pros/cons and any other general information about it.

Thanks Guys,
Charles

It's primary use in on boosted engines. Look up Snow Performance.

I had a snowperformance.net system on my supercharged NSX. Loved it - lowered intake temperatures under boost by about 150 degrees, allowed me to run more timing and no predetonation. Not sure if it would be a big advantage using carbs, but their website is full of information. Cost was about $500

Charles, I had several buddies running water/meth injection on Chrysler LX platform cars (Charger, 300, Magnum, Challenger) back when I had a Magnum. They saw some decent gains on NA cars, as well as forced induction cars. I don't know how much it would help, but it wouldn't hurt. For the money, you would see better gains with N2O, though.

It's mostly out of curiosity that I ask, but I don't like all the pressurized crap that comes with n2o. Mainly looking how to squeeze a couple extra ponies without breaking the bank. And i know that you can run windshield washer fluid in place of snow performance's "boost juice" which is a cheap way to gain some hp. Im also kinda curious about cryogenic cooling fuel rails (run on CO2) but I haven't heard much about them either.

2 guys that run it locally up here, both use it with supercharged engines. I don't know much about it though.

Water/methanol is not a power adder.

It is added to poor fuel to slow the burn IE: increasing octane rating. It saves cost of High octane racing fuel.

I used it years ago on my turbo boat, it helped lower temps and allowed pump gas. It was much faster on racing fuel.

FYI

the use is for high compression or engines under Boost conditions requiring a high octane fuel.

http://www.alcoholinjectionsystems.c...icle_info.html

Water methanol injection has become a tried-and-true proven way for users to effectively increase their 87-93 octane pump gas. Depending on the amount injected and the type of mix used (pure water, pure methanol or a mix of the two), gains up to 10-25+ points in octane can be achieved. Thus making 91 octane pump gas act like 105-116 octane racing fuel in their engines. Thereby eliminating our dependency for notoriously expensive racing fuels, which can cost upwards of $8.00-$12.00 per gallon as so many of us have reluctantly had to use in the past. Costing only pennies to operate when using 100% water, its also a far more effective, affordable and convenient to those expensive octane booster fuel additives as well.

Here is a general explanation about octane.

Its known as a "chemical intercooler". Ask anybody that runs class race that prohibits mechanical intercoolers and they will tell you it adds power by decreasing IAT's substantially. These guys are already running C-16 or Q-16 race fuel. On boosted cars of course

OK so it will work something like having a strong racing gas in your car versus having pump gas right? So wouldn't that mean more power if the fuel is more volatile when it is compressed and combusted?

newbie here how does this system actually work and i mean in detail cause alot of people can use this if it extends the gas milage by a positive percent. and does it do any damage to the engine.?

Ask your self a simple question.

Is water combustible? Does it burn?

==============================================

You have to understand what octane rating means and how fuel burns under compression.

imho
