    Let's talk Water/Meth

    Guest-only advertisement. Register or Log In now!
    This is intended to be a living post, I will update it with information as I have it.

    There are a few of us experimenting with Water/Methanol Injection(WMI) now so I figured it was time to consolidate information.

    Overview:

    FAQ: (Source)
    Code:
    Is it safe to spray water methanol injection through my supercharger?
    
    Yes, its safe to spray water methanol injection through your supercharger. We have set up hundreds of systems for customers over the years who are doing just this. Furthermore, you can find countless others on the internet who are doing the same with competitors systems. Spraying through the supercharger is extremely effective way of cooling off the supercharger and its rotors and housing. So much that if you are familiar with how hot your supercharger is after shutting of the car just after normal driving. If you ever get the opportunity to watch your car dynoed in person. After they finish a pull. Walk over and cautiously place your hand on the supercharger. It will feel warm to the touch and sometimes almost cool. Where as without the water methanol injection, you wouldn't be able to touch it! I have found this to be a quick and easy way to tell if the water methanol injection has fired off during a run on the dyno before waiting for the data to display on the dyno's computer showing air temps. Try it out for yourself and you'll be surprised how cool your supercharger feels with water methanol injection.
    Will it hurt the bearings on my supercharger?
    No, the water methanol injection will not hurt your bearings. We have customers who have been running water methanol injection through their positive displacement superchargers, on daily drivers, for years without any issues. While we can not see inside the supercharger while the methanol is spraying. We can tell from looking at other information and signs. It appears the majority or entirety of the water methanol injection is flashing off instantly once it comes in contact with the hot rotor pack and housing. The water methanol injection is short lived and evaporates to quickly to make its way back and into the bearings.
    Will it pit or corrode my supercharger?
    No, spraying water methanol injection will not pit or corrode your supercharger. While it's a reasonable and understandable question since the supercharger rotors and housing are made of aluminum. The methanol is too shorted lived and evaporates immediately before it is allowed time to effect the aluminum surfaces. Unlike if you store methanol in a aluminum container where over a period of days and weeks it will eventually corrode and pit the aluminum.
    Will it effect the coating on my supercharger?
    Yes, for many of the superchargers, those which are not anodized, over time it will remove the thin coating on the rotors. If you were to ever remove the rotor pack after having ran the water methanol injection for a period of time. They will almost look like they have been polished. While the water methanol injection will remove this coating. It has not proven detrimental or effected the performance of the supercharger. This coating is designed to wear and will eventually deteriorate over time regardless if water methanol injection is used.
    For the most part you will want to stick with a "Stage II" kit as these allow for progressive spraying based off Boost.

    Here are the common companies listed in no real order: Aquamist, AEM, DevilsOwn, Snow, Coolingmist

    In addition to the kits above you will need some place to route the nozzle. Common places are at the throttle body spacer, intake, SC elbow and at the intake manifold.

    Here is a question I have since these cars seem to adapt, even to a tune. If you change from your 93 tune to a 104 tune many people have said they have to driver the car for it to adapt.

    That being said do you have to run a meth system on all the time to see the results. Meaning you can't just have it on a switch for situations where you going to get on it and want extra power and expect to see results.

    THEN THEN THEN Rinse & Repeat!

    Where do you order your meth from and do you premix into a container and store it until you need it, or do you mix it only at the point of needing to refill? Where did you personally install your reservoir and pump?

    Nvm, found it in another post of yours:

    Mine is on all the time now. Originally the plan was to put in a kill switch on only flip it on as I need it. Coming on at 8 psi I tend to not use a ton of it.

    I've been topping off my tank every time I fill up with gas. Usually, it is about 1/2 way down.

    When I went to the track a few weeks ago I burned through 1/2 a tank in the 13(?) passes I made starting at 5 psi.

    Even when I was turning it on and off like crazy it will adjust pretty quickly. (Assuming your fuel trims aren't way out of wack like they were with my old Revo setup )

    I have a few options:

    1. You can buy cans of M1/M5 at local performance shops, tracks or auto parts stores. The best I've found around here is 5 gal pail from a local performance shop.
    2. I've reached out to local chemical companies and they can provide me a 5 gal pail of pure methanol.
    3. You can buy jugs of pre-mixed "boost juice" online or in some stores.
    4. Blue anti-freeze and heet. (Widely available but kind of pricey for what you get)

    I mix up my batches of W/M in a gallon jug then dump it into the res. This way I always know the ratio. Technically you are supposed to mix them by weight not volume. I'm lazy and just do volume.

    I keep the extra in that jug until I empty it(it might sit for a week or two at the most). I have a corner of my garage dedicated to mixing meth like Walter White.

    My res and pump are installed between the firewall. I've posted pictures before but will do more once I type up a better post.

    Maybe Im not reading this right, but is this showing that the IATs with spray is better/colder, but the timing is actually better without spray?

    Nice thread. I think meth injection is a highly overlooked mod.

    A couple items to add to the IAT aspect. From runs last weekend, 71*F ambuent, 700ish DA, all 5 runs were consistent. IATs starting at 49*C and finishing at 69*C. This is with 500cc nozzles at the TB plate and 900cc on the intake tube right after the airbox, 1400cc total.

    I can't say whether or not one way or the other makes a difference. I can say that along with the cool to touch supercharger observation by Whiped, adding a nozzle on the intake tube makes the entire tube and throttle body pretty damn cold after a hard run.

    My setup:
    AEM 30-3300 V2 Kit
    ECS Boost Tap
    IABed TB Spacer (Contact Issam to make you one)
    034 90 deg fitting

    AEM has a pretty comprehensive installation guide you can find here: http://aemelectronics.com/files/inst...ns/30-3300.pdf

    I played around with different mounting locations but ultimately ended up placing it between the firewalls.

    Mounting the reservoir:
    I used some aluminum strips I picked up from the hardware store and bent them by hand.

    I sandwiched the strips behind the soundakator box in the middle of the firewall section:


    The res fits very nicely here but you will need to trim the cabin air intake a bit to make it fit correctly. I just hacked at mine with a Dremel. I then sealed it up using some random acrylic I had lying around:

    Mounting the pump:
    I relocated the alarm horn to the right of the reservoir using the bracket I made above and some bending skills. This freed up an existing standoff to use for the pump.

    Using this I then drilled a pilot hole for the other top mounting point and mounted the pump using a sceew provided with the kit. (There is a bunch of insulation behind the firewall so you aren't risking too much drilling here. Don't go crazy though)

    Installing the Nozzle:
    Pretty straight forward but I'll post a pic just because.

    Remove the TB.
    Using the Spacer figure out the orientation you want it to go.
    Install the nozzle and check fitment.
    Plug the other hole.
    Bolt the TB back on using the provided seals and bolts.


    Installing the Boost Tap:
    Just follow the guide on ECSs website. (I had done this before for my boost gauge)



    I just T'ed my boost tap line inside the cab to provide boost to the controller.

    Wiring:
    Refer to the AEM guide linked above for what wires go where.

    I grouped them together... Shit that stays inside the car. Shit that needs to go through the firewall.


    Remove the ECU and run the wires that need to go through the firewall that way. Using a coat hanger or some other contraption force the wires through the self-sealing gromet on the edge of the ECU box. Zip tie the wires down the ECU will still fit.



    Now run the wires to everything they are supposed to go to.

    I used the open terminal for the battery positive:


    The main ground for the negative:


    Piggy backed the soundakator fuse for the switched ignition controllor power. (I don't have a pic because my fuse box is a mess and would just confuse you) You can add a switch here to kill the system.

    Then plugged everything in and mounted the controllor in an accessible but not noticiable spot. (Near the ODB II port)


    Now follow the test procedure to make sure everything is working correctly, button everything up, add more zip ties than you think you need and you are done.



    Extras:
    If you are feeling creative you can install a flow sensor, I forgot to run a wire for it and have been too lazy/buzy to add it.

    I'll post some interior pictures later. I don't have them handy currently.

    That was my old tune that would bog when I started spraying due to massive corrections of fuel trim.

    This was with my Revo pump tune with the CW stacked 7-1 running E30. Fuel trims were 20+% and would bog when spraying.

    My 034 tune loves the meth and I am not even tuned for it. Spraying I see a massive drop in IATs and a 2+ degree increase in timing. (Increased timing, less knk)

    -----
    @nsantos, thank you for the info. I think I will step up to the 1000cc nozzle sometime in the near future. I'll run my setup as is on the dyno/track tomorrow.

    Also, post pics and I'll add you to the cool kid list.

    I heat wrapped my whole intake tube as it would get hot from the engine. It is cold to the touch as is the SC after a few pulls.

    If you let it sit for a while it will heat up though. Perhaps it is time for a KC setup for the staging lanes

    Why set the kit to shut off before peak boost? I assume you're making more than the 16psi the flow stops at. Is it to prevent a post-shift bogging issue?

    After 16 psi it is spraying at max.

    FWIW I usually see around 22-23 psi.

    Now I get it.

    What psi were you seeing on regular stage 2?

    18-19 with the CTS pulley.

    The only downside to spraying is it makes the SC quieter lol.

    Nice thread Geoff!

    I was contemplating running meth injection last year, but decided against it. Now after seeing matts crazy mph I'm thinking I will go ahead and add it this summer along with headers

    Any dyno charts of what 22-23psi looks like on your car?

    Hopefully tomorrow. 21lbs netted me 415awhp, I've posted the graph before. You can also check out my virtual Dyno thread, I'm curious how close it will be.

    They are the nozzles. Went from 500 to 1000cc

    My observations on nozzle sizing:

    91 Oct on EPL 91 file:
    -1000cc was way too much, ran super rich, but IATS were nice.
    -500cc was perfect. Lambda looked good, IATS were low and timing pull was almost completely gone

    Race gas mixes on EPL race files (e85, e85 blends or 100+ Oct)
    - any size between 500cc to 1400cc seems to work. I find that about 900cc was the sweet spot. Less timing pull, and no more than 20*C delta on 1/4 mile runs

    Logging is tricky with Meth as the tank I use is only large enough for about (5) 3rd gear pulls. Here's a shot of my reservoir setup. Window washer tank from Amazon and Devils own tank nozzle and level switch.

    Terrific thread Geoff!

    I keep telling myself I won't add a water/meth system to this vehicle ... but the dialed-in benefits are clearly there.... Hmmm....

    Couple questions as I am a novice on this setup. Is it worth the time and money for a DD? If it is what's avg cost for the setup? Thanks

    I daily mine, most the time it's not in boost so you don't consume much.

    I'm pretty sure I have around $500 into my kit all said and done.

    Around 500 as well, less meth refills.

    Great thing about running meth when you're not tuned for it, it doesn't matter if you run out!

    True depending on what octane tune the person is running..
    When I was running 91 octane on 104 file and meth
    I saw up to 13 corrections during a long hwy run when I was logging and ran out of meth half way through the pull.
    I'm only running e30 now since I found a local station that sells it at the pump..
    So I don't have to worry as much about that.

    Very true and good point brotha. My statement was assuming the user was running the correct octane and not relying on the meth to boost octane, only to help cool iats.

    Good to know and thanks for the advice. I may consider this option just to keep the iat down.

    I have studied this subject heavily and have also contacted several builders and manufacturers regarding this mod. There are hardly any if none at all negative side effects to this mod. It creates cooler temps in the upper plenum and intake air as well and leads to a cooler denser air feed into the turbos themselves. It also lowers turbo temps. This leads to big HP gains respectively. The only downside I found from my research is this: if you only have your car tuned for a meth setup and accidentally run out of the go go juice it can cause problems and possibly damage to the engine. I was told that damage was a very low possibility though unless you were running a very heavy psi meth build. So as long as you watch your meth level its hard to find a downside.

    Figured I'd update this with some experimenting I did over the weekend.

    Switch to the 1000cc nozzle, using 50/50 w/m coming on at 8psi and maxing at 24. (My car only hits 23 fwiw)

    IATs were lower and there was zero timing correction running at the track. (See logs above for an example)

    I made 6 passes at the track and consumed roughly a 1/4 gallon.

    At this point, I think I am going to switch it to using 60/40 w/m coming on at 8 and maxing at 20.

    Since I am not tuned to take full advantage of the octane boost yet the extra water should aid more in cooling. Once I get things dialed in with 034 I will request a more aggressive tune and up the meth level again

The only downside I found from my research is this: if you only have your car tuned for a meth setup and accidentally run out of the go go juice it can cause problems and possibly damage to the engine. I was told that damage was a very low possibility though unless you were running a very heavy psi meth build. So as long as you watch your meth level its hard to find a downside.
