Can you really run windshield washer fluid in the place of stright meth mixed with water??? how safe is it?

Not really relating to your question but my washer fluid reservoir is tapped and thats where my alky suppy is. I run 90% rubbing alcohol when I cant get the good stuff...

Yes you can, but its not reccomended. Washer fluid becomes crusty when dried up, and you dont want that crap clogging your pump or nozzles..

Not really sure why anyone going to the trouble of setting up a kit and tuning it would run anything but 100% methanol... unless you're not going to spray that much and are looking mainly for IAT reduction, without the octane bump.

There is the fact that a methanol fire would be both big trouble and invisible, I guess. But then I look at all the fuel already plumbed all over my car and I think that point is moot.

I was told to mix 50/50 with water. Why is that, what advantage do you get going either way? how fast do you use it up?

a 50/50 mix is not flamable. (i think) the 100 straight will perform better.
water does help cool and clean also.

Actually, 50% methanol in H20 is flammable. You won't see the flame, but it burns.

Using 100% methanol adds a higher octane content fuel along with the cooling effect, further suppressing detonation. Depending on how aggressive you want to be, you can also add more timing under this cooler/higher octane condition to make some more power.

Adding water acts as combustion quencher. It will help tame the flame inside the combustion chamber, but at the same time wont hurt HP. I would run straight meth on the track and 60/40 water/meth on the street.
Plus when you spray water, it acts as a stream cleaner inside your engine, cleaning out all the carbon and oil and junk

Not sure I follow the combustion quenching theory, unless you are reffering to uncontrolled (read preignition) burn at the edge of the combustion chamber. Water injection accomplishes several things:
1. The latent evaporization effect of water on the incoming air charge is high. I am almost certain that the value of water is higher than methanol in that regards. I am still researching that though.
2. The energy released during the phase change from liquid to gas is enormous. I believe the volume increases close to 1600:1

Well, yes, in easier terms, the quench will reduce the heat of the flame, low enough to practically prevent any "hot spots" from forming anywhere in the combustion chamber

It's being done...I personally would rather not, but that's a personal preference. Fogoing Meth, I would use like a 75% isopropyl, 25% water...something of that effect.

am I better off running rubbing alcohol than meth?

check out devilsown.com....they sell the Meth kits and they clearly say you can run it 50/50 with washer fluid and water.

Water is the absolute best at controlling detonation. Hell, if you spray enough you can't even get ignition. With that being said, I run 100% meth in my kit. My IAT's post intercooler are too low to flash off water. Without instant evaporation, the potential HP benefits are lost. The meth has a much lower flashpoint, and still has a combination of high octane and high latent heat of vaporization. I have seen IAT's at the end of the 1/4 that were still 20* below ambient at 10#'s of boost. On the same day without meth, the IAT's were 60* above ambient. And if there is any confusion, methanol is wood ALCOHOL and ethanol is grain ALCOHOL. There are several different types of alcohol. I just get tired of reading "meth or alcohol".

all windshield washer fluid is, is 60% water 40% meth. as long as you make sure you get the right kind cause some have weird stuff in them. but walmart -20* is just water and meth so i see no reason why you couldnt run it. at least on the street, and then if you really wanna be safe run 100% at the track.

I just switched from washer fluid to a 50/50 mix of washer fluid and meth (there was some left in the Resevoir) and the car felt noticibly better not even tuned for it.

you run a t70/10psi with 36#injectors?

Water displaces fuel. In other words..Water takes the place of fuel.

Methanol is a fuel. Actually a very nice and CHEAP racing fuel.

You cannot tune to a percentage lets say 50/50 and then go to straight methanol without retuning. The higher the water content, the leaner it will make your mixture. And the higher the water content, the higher the heat present needed to "flash" the liquid being shot in. Water flashes at 180 DF. Methanol is 70 DF. Shoot water into an intake at 100 DF you will have droplets getting into your combustion chamber. Get really aggressive with the water, you will hydro the engine breaking pistons/rods/etc. This becomes more so a problem in winter conditions.

The use of windshield washer fluid in injection systems belongs on the ricer forums. Just like Apexi wings, mufflers, neon, stobes, etc. Next comes "What about the nitro stuff "

Go to www.corvetteforum.com and type the word Meth in the search engine. You be pressed to find to many running anything but straight methanol. Off course we're dealing in cars making more power using the same engine.

Why anyone serious with their vehicle would run a questionable liquid, is like getting 93 octane gas at the Quicky Mart and expecting it to be the same as BP/Mobil/Shell/etc.

Straight methanol user here as well. That water hurts power. Always has.. Too many dyno pulls, time slips, datalogs, etc.. to say otherwise.

you guys should read this. Taken off the camaroz28 website its a pretty detailed look at the water/meth idea.
