meth/water injection info

Use your nose. If it smells like Bacardi 151..it ain't washer fluid..

[cuda6666]

Whatever. Now what about the Arab/Israeli problem?

Can't see it from my house..

i think the only thing that needs to be said is anything injected into the motor is considered a fuel. using the word fuel will then have other rules that take over to say what is required for safety.

section XI
11. Fuel cell (tank) must be separated from the passenger compartment by a metal or composite bulkhead. All fuel and oil
lines passing through the passenger compartment must be either steel tubing or steel braided hose (Aeroquip, Earls,
etc.).

[breakaway500]

So all windshield washer fluid ("fuel")injection system cars, which have any windshield washer injection hoses running inside the passenger compartment, will have to be made of braided steel or solid steel lines? (stainless needed for water/alcohol) Seems like a costly solution to no apparent problem,to me.The stuff does not burn and is only toxic if you drink it. Does any other race sanctioning body consider windshield washer fluid as a fuel?

[nhsilversti]

not quite what i said....
anything injected INTO the motor is considered a fuel

scca considers methanol to be an alternative fuel which is not allowed at their events.

for me water/meth injection allows for the use of 93 octane versus 100+.

And when was the last documented case on planet Earth in which a water/meth injection system contributed to a fire?

[breakaway500]

Like I said,windshield washer fluid will become a "fuel" if injected into the engine,as you propose. It's not a fuel.It is an additive. An engine will not run on windshield washer fluid. Yes, many racing sanctions consider 100% METHANOL a fuel,because it is, in undiluted form. But, not as windshield washer fluid. Why all the fuss?

Windshield washer fluid burns just fine. Tried to help a trucker put out a brake fire once. The only wet stuff we could find was washer fluid ( or maybe antifreeze? ). I remember it burning as soon as it hit, so we resorted to shoveling sand onto his brakes...

I would think these setups are asking people to put in more methanol until they start winning. It just seems tempting to start adding more. So you should expect this to be quite flammable.

[breakaway500]

Windshield washer fluid will NOT support combustion. Neither will ethelyene glycol (anti freeze),however anti freeze will flash when sprayed on an open flame.You probably grabbed a gallon of anti freeze for that brake fire. Brake fluid will actually flash when sprayed on a fire as well. None of the mentioned fluids should be considered a fuel,however. Mazda injected anti freeze in early Rx7's as a cold weather starting aid. Not sure if it was to help combustion or help seal the apex seals.Maybe both. Rotary engines are so strange..

And nobody just keeps dumping in more methanol in hopes of getting more power. You have to tune for water/meth. It gets expensive doing dyno runs after every extra splash

from original post "Care should be taken to avoid skin contact.Methanol in a 50/50 mix with water is NOT flammable"

this is not true, 50 meth/50 distilled water does burn, rather nicely i might add. while it is a little harder to light, the point is it does burn.

[breakaway500]

I will have to try it.I can take one 12oz. bottle of Heet and one 12oz bottle of water,mix them,and see if it will support combustion. I like experiments!

Windshield washer fluid does burn. Quite well in fact. I just did it in my kitchen and think I should have used a much smaller quantity

Put it in a pan and boil it, stand back when you light it. An issue with the fuel aspect of this is that it is run thru hoses under pressure. If there is an accident, a hose or connection can be broken and the fluid pumped onto hot surfaces. Do these use actual injectors, so that they might be under pressure even when the motor isn't running? Say after an accident .

It doesn't sound expensive to add more meth and re-dyno. If you don't have a turbo and need more power, your looking at thousands of dollars. Here the problem is basically that you started with water, which is used to put fires out!

http://powermist.com/methanols.html the pure is what i use and mixed 50/50 it does burn but you might have to turn off the lights to see it. i had never tried to light washer fluid.

heet uses 99% alcohol not methanol unless they have changed.
