LEts talk meth injection

[h22sparkle]

I havent seen this topic touched in a long time. okay theres different ways of making meth injection work for cars.

Theres racegas which you can use ethanol or denatured alcohol with 2 caps of oil from what ive heard which you can make race gas with.

Or you can go and use it through nozzles of an injection kits. most of the time alot of people will use windshield washer fluid the blue kind not the green or the orange. They contain a certain kind of icing agent and propyl glycol which is a certain kind of antifreeze.

You dont want that in the cylinders to get burned off this can ruin your engine. the proper way of making sure that doesnt happen is to not buy that and shake up the antifreeze it must be blue. And it must not contain excessive bubbles which indicate theres alot of deterdents in mix.

When making your own brew you have to make sure you tend to the lines to make sure there are no leaks. And also which i think is really important is to not use tap water.

It contains impurities which will gather and clog the nozzles overtime . Basically hindering the spray patter to evenly distribute the amount of pressure the pump is trying to maintain.

Now as far as the pump and meth mix. Others use 100% meth others use a 50/50 mix which contains half water and half methanol by weight. Geting in more technically the methanol is lighter than water. So you can measure them by volume you have to measure them by weight.

The 50/50 mix is more ideal as it cools the temperatures down its not so easy to ignite as to where methanol heats up when ignited and burns slower.


The 100% meth mix is good for tuners who tune their cars and if not careful it causes strain on the fluid injection pump. It wears away at the seals and the actual pump itself.

It also causes a very rich condition at that and if not careful you can wash away your cylinders,cause and even more rich condition,and a nasty backfire from all that unburnt fuel.

Will fill in more about water/meth injection tommorrow. If anyone wants to throw in more info from what theyve learned about water meth injection please feel free to chime in. Wikked and others

Okay basically the purpose of meth injection is to create power. It creates power through proper tuning. When you lean out the car you want something to supplement aside from fuel . You want to keep the combustion chambers cooler than fuel will allow it.

Thus thats where the water meth injection takes place. When a car is being tuned to make more power you want more slightly more air than fuel but not to much to a point where it can seriously damage the motor.

Its for naturally aspirated cars and forced induction cars alike. When the alcohol and water goes throught he cylinders it makes a bond down to a molecular level . The alcohol a cooling agent and water another cooling agent both keep the combustion chambers cool.

But the alcohol raises the octane which basically gives it less of a chance for detonation heling the fuel burn slower than usual. This is a double edge sword though. Without the power link with enough water to keep the combustion chamber from getting too hot because it works as a catylist and has a slightly higher boiling point it will work against you.

You dont want that because with just excess fuel only without something to keep the egt's down at the same time your raising the octane you can really mess shit up.

And you dont want too much overfueling in the system to where the point where your slower than usual thats like telling someone to have a drink and pouring a bucket over their head,basically drowing you out.

or
basically the trunkmount which you can tuck away with no issues

dude u are running meth injection tho. ive seen your car at the meet last year

[h22sparkle]

for example say your ening when its running notice how it feels really hot to a point where you can feel the seering heat eminating from it.

Well with cooling mist you dont. For example when the water goes into a fine mist like say from a set of irrigation lawngardening sprinklers notice the fine mist when it gets on your skin how your skin feels slightly cooler than when its drenched with water.

Thats how the system works. When its in a fine mist it works better The evaporation point where its at helps cool things down better the alcohol brings up the octane and the cooling effect of the water.

the only question i got is, how much hp can u make on 93 + water/meth before you need to switch to race gas?

Honestly id say to about 440 to 500 if your lucky to 500. but there are others who made more its all in the tuning.

yea. thats good tho.

i think we need a topic of e85 to. i wanna learn about that

If you look at it you can make your own race fuel if youd like but its a little tricky. Race gas is good but it gets pretty expensive if its yoru daily driver. If its not its still gonna hurt.

Race gas goes for damnnear 80 a pop out here. Thats not alot but it does get costly if your driving around with it not racing it.

But meth injection honestly in my eyes not saying its for everyone but atleast it gives you an option when its not in use you can use for your benefits of when you want it or when you dont want to use it.

true. what about 93 with striaght meth injection?

[h22sparkle]

Water injection has the ability to supress detonation. but the other benefit of all is damn near unlimited supply at almost near zero cost. Compared to most race fuels and lets not forget about shipping costs. Which costs more because its a hazardous material.

Detonation occurs when the flame in the combustion chamber doesnt burn properly instead it explodes. like a big as spike and im sure alot of people in tuning heard this sound before tink,tink,tink kinda like marbels being dropped in a aluminum pot.

When meth injection comes into play the water gets in the engine with a fine mist that takes the heat,then it evaporated and turn into steam that takes the heat too because it has a high tolerance for that and acts as a anti detonation front. So while the motor gets steam cleaned it keeps it cooler than usual.

You see unlike drag racing fuel which is 100 percent methanol has the ability if your not careful to wash away your cylinders and overcooling the motor basically overfueling it too.

But with methanol you cooling it cutting some methanol out to a certain degree and keeping the motor clean aswell.

For turbocars it works wonders. Especially in the sumer when its hot. For those with small intercoolers itll help out alot to a point where it would even cancel out the need for a bigger frontmount.

[h22sparkle]

true. what about 93 with striaght meth injection?

Well it depends on how much you intend to use. First you have to find out your injector size to distribute how much your going to shoot into the motor.

Id recommend 1 injector but 2 small daul injector help out aswell 1 before and after the iat sensor 1 closer to the throttlebody. And you can mix it yourself.

But with straight meth injection you had better have something pull fuel when you squirt it or your gonna hear a loud bang everytime its shot in like your overcooling if your running rich all the time.

[h22sparkle]

You can try the windshield washer fluid thing or mix your own you can use the blue winshield washer fluid like valuecraft.

But not the orange or green winshield fluid they have detergents in there that will mess up your motor.

[h22sparkle]

Usually theres no need for 100 percent thats if your tuning it seriously all the way. But if your wanting a balance in it the best mix is a 50/50 by weight not by volume like for example. Ill take 1 cup of water and 1 cup or alcohol.

Water is more dense so it weighs more than alcohol so you would normall add less water to the alcohol. because it has to mix in with both fuel from the fuel injectors when it goes into the motor.

[h22sparkle]

take for instance methanol which is a fuel that your car can burn. It burns half the time as gasoline. the good thing about it it has an octane of 120. So basically it more 3 times the heat than gasoline by itself.

And water mixed with it removes twice the head than gasoline. So now you got 6 the fuel the meth and the water. All absorbing heat letting the motor breathe.

you want to keep a balance with this kind of thing. If your using jsut straight meth your overcooling it to a point where it doesnt want to cool anything anymore and it will turn around and create heat
