Alcohol Injection Systems, LLC would like to personally address and answer any questions members may have about the use and effects of water alcohol/methanol injection. We found many of the responses and posts here in this forum to not be completely accurate.

Let us know what your questions are so we can help better inform everyone about water alcohol/methanol injection and how to tune for it properly.

Have a question and want to speak to someone directly about water alcohol/methanol injection. Give us a call directly at 1.801.447.2559.

which option is better alcohol or methanol??? ill be tuning soon so let me know.

AIS

Methanol is an alcohol. The word "Alcohol" is a generic term. There are many different types of alcohols available such as methanol, ethanol, isopropyl, etc.

Methanol is the preferred alcohol to use. Windshield wiper fluid rated for -32 degree below zero contains between 35-38% methanol depending on the brand. This is an affordable and easily accessible fluid for most and works great. If you add one bottle of HEET (12 oz. of 98.% pure methanol) to one gallon it will increase the methanol content by 10% giving you roughly a 50/50 miz of water and methanol.

We recommend a mix between 50/50 to 25/75 water methanol. We've made or best horsepower gains using a 25/75 water methanol mix.

When you inject water/alcohol the alcohol portion provides instant cooling (as it quickly evaporates), added fuel, increased octane (when used with pump gas) and burns as part of the combustion process while reducing combustion temperatures and EGT‘s. It should be noted that alcohol has a much lower latent heat of vaporization then water therefore it begins to evaporate instantly when injected into a hot air charge.

Water on the other hand has a very high latent heat of vaporization.

Definition of Latent Heat Of Vaporization: “latent heat” is the amount of energy in the form of heat released or absorbed by a substance during a change of phase. (i.e. solid, liquid, or gas), - also called a phase transition.

The energy (heat) required to turn water into a steam (to begin evaporating) is substantially higher then that of alcohol. When atomized properly water alone works well at cooling air charge temperatures. However, when compared to alcohol, testing has shown water does not have as great of a cooling effect on the air charge temperatures as does alcohol. When water does evaporate it turns to steam. This steam stabilizes and slows the combustion process acting as a anti-detonate (suppressing detonation) essentially making it an effective octane enhancer.

Together, water alcohol injection cools the intake air charge temperatures, reduces combustion chamber temperatures, thus cooling and protecting the top of the pistons and the top ring as well as lowering EGT's and cooling the exhaust valves.

does this system put the injection before the supercharger or after? and if after then how?

I noticed you guys are from Ohio... We have semi-annual meets in C-bus, look for the one in April we would love to have some of you guys come out.

We recommend installing the nozzle just before the throttle body. You will notice one of our customers placed the nozzle after the throttle body. It can also be done this way. When doing so, we recommend relocating the check valve from the back of the car to just behind the nozzle.

Let me know if you have any other questions.

Sounds good. Is there any event s coming up before April?

what does this do to the coating in the supercharger? how bad does it wear down?

AIS

The coating on the rotors holds up just fine when using a 50/50 mix. When using pure methanol it will slowly remove this coating. Even with the coating completlelty removed we have not scene performance effected much.

For example many of our Corvette customer with the Magnason superchargers run pure methanol as many of the Corvette shops who build these cars also prefer it as well. When you pull the supercharger apart the rotors are spotless with all of the coating removed. Kenne Bell, another supercharger manufacture, builds all of their superchargers without coatings on the rotors just to inform you.

Let us know if you have any other questions.

apart of the lots of benefits it gives, how safe is for the motor? can it damage it? if it does what does it?

AIS

No, our water methanol injection system will not damage the motor. It's important to understand we are only injecting a very fine controlled mist of water methanol into the intake of the supercharger. Much of this mist immediately vaporizes as it hits the rotors of the supercharger as it passes through it. Understandably we see the concern many have initially when they first hear about injecting water into their engine.

Most of our customers go through a tank (1.5 gallon) of water methanol in 3-4 weeks. This should help give you a better understanding of how much fluid is used.

With the use of a water methanol injection system we have actaully reduced engine failures of supercharged and turbocharged engines. To understand more why click on the link below.

Let me know if you have any other questions.

cooljake73

so mount the nozzle on the intake ur saying

is it only recommened for racing or ok for dailly driving to

Raven SS

its the best place to mount it reguardless of driving...if ur racing u might spray after the blower also but not recommended for dd...

i have a question...whos the best water/meth company?!? lol u are!!! haha cheesey plug for u rodney

cooljake73

so basically if i mount it on the intake im fine

Raven SS

yea thats where mine is

cooljake73

what do you use in ur mixture.....the red heet bottle or windshield fluid

Raven SS

boost juice is one alot of people use

do you guys offer a set up like my buddys where the meth does not kick on till a certian psi...cause my daily driving is alot of stop and go...

burntorange

I run pure methanol

forced_induction

i like that idea, save mix and money

Raven SS

thats what most kits do..they either kick in a WOT or the boost level u have it set for. the best thing about AIS is there progressive controller..its the best thing offered on the market! u can have ur meth set at min pressure at say 5 psi than by 12 psi its at max and it will slowly rise..no other kit offers that so u have to set it for like 13-14 psi so u dont dump meth into ur engine all the time...

AIS FTMFW

forced_induction

i like i like, i wanna get a water/meth kit come this spring, think i know what one im getting

splitimage

its tuned through the maf-t, snow performance uses the same technology.

i should add that through testing, the lsj reacts the best to a wide open spray, instead of a raped rate. When i was running mine before i sold the redline, with a 2.6 full exhaust intake 60's tuned and running 80/20 meth water on a 225 ml jet i hit 294 whp on the heaton!

I had it tuned to begin spraying roughly around 11 psi.
