First off the Pump.

This pump will be for a setup running nothing stronger then a 50/50 mixture of water and methanol, for anything stronger then that you will need a different pump.

Here is a link explaining why: http://www.srtforums.com/forums/f218...thanol-240309/

So first you start out with the pump itself, this is the biggest thing. The shurflo 8000 series is what you want, pretty much anything from that series will work. They are all rebuildable and modable for more pressure ect.

- The cheapest option will be something like this which i found on eBay, only a few left though.

- Here is the same pump for sale at northern tool for a little more: http://www2.northerntool.com/grounds...tem-342811.htm

There are other deals to be had on similar pumps if you look around. long as it is an 8000 series pump you should be fine.

- If you want to step up to a better pump and one that can take 100% meth you have these kind of options: http://www.alcohol-injection.com/pumps-40/

They also sell upgraded seals there if you get a cheaper pump and want to upgrade later (along with many other sites).



Once you have the pump, you need fittings.

If you will be using the factory washer fluid reservoir you will need the below parts. If this is not the case then you can find pre-made reservoirs with the fittings already installed pretty easy.

This part of the list is what both supercharged/turbo guys and NA guys will need, it has all the fittings you need to make it work. I will make a separate list the different switches you will need depending on if you are boosted or NA.

- You will need 2 of these fittings for the pump in/out: http://www.mcmaster.com/#51495k117/=99xou3

- You will need 1 of these for the bottom of the washer fluid reservoir, i used this and had to make sure it was installed exactly where i put it for it to seal (there are reinforcement ridges on the side of the tank that will keep it form sealing if installed in the wrong place). Do the same and you should be fine. http://www.mcmaster.com/#51495k253/=99xrxt

- I have a 5gph nozzle picked out, which on a 50/50 mix or washer fluid should be about right, you can also adjust the pump pressure to adjust the flow rate as well: http://www.mcmaster.com/#3178K75

- Fitting to attach to the nozzle: http://www.mcmaster.com/#51495k262/=99z5yh

- The tubing you will need to hook everything together: http://www.mcmaster.com/#5112k53/=99z68f min order of 25 feet

- Relay (any will do, this is a good price for a relay with pigtail though and you might order something else from them anyways: http://www.alcohol-injection.com/30-...-relay-16.html

- LED: http://www.radioshack.com/product/in...ductId=2062569



That all the basics, total so far is about $90 for everything minus basic wire/connectors ect which you can source locally from Harbor freight/northern tool/pep boys/home depot


You then need electrical switch to turn the pump on.

First off the supercharged/turbo way of doing things.

- Pressure switch: http://www.mcmaster.com/#3460k21/=99z7pm

For a supercharged/turbo that is what you need + a T Fitting and Barb adapter (actually cheaper to get that from home depot) for the vacuum line



For N/A you will need a switch hooked up to either the gas pedal itself, or the throttle body. This will take some DIY work but is not hard, look up how guys hook up WOT switches for nitrous systems for inspiration. Basically you will get some bar stock from home depot and bend it into shape so you can use a switch like this if you go with the TB:

http://www.mcmaster.com/#7658k11/=99zcv6

Or this if you go with the gas pedal:

http://www.mcmaster.com/#7090K37

This part i can't really guide you in since everyone will do it differently, basically just find a way so that switch comes on whenever your foot is to the floor (or wherever you want it to).



Thats all you need to have a meth injection system. Although there are places you can upgrade if you have the money.


- The better pumps listed above obviously is 1 place.

- Other things i would look into would be a low fluid level sensor, for obvious reasons: http://www.alcohol-injection.com/sel...switch-71.html

- Another pressure switch, this one a high pressure switch, this will be to put in the high pressure line of the meth injection, so you can see when it actually has pressure in the line: http://www.mcmaster.com/#3460k61/=99zgkk

- you will also need an adapter if you do that: http://www.mcmaster.com/#51495k143/=99zid0 & http://www.mcmaster.com/#9171k71/=99zjlx

- I would also really look into an upgraded nozzle, i really like the devils own nozzles: http://www.alcohol-injection.com/out...zzles-135.html & nozzle holder: http://www.alcohol-injection.com/met...tting-284.html

- Upgraded bulkhead fitting is nice too: http://www.alcohol-injection.com/fil...k-tap-274.html

- For the those that are tuning for the meth injection a check valve is a good idea, long as the nozzle is before the TB though it is not a must you will just suck a little fluid through the system while driving, no big deal. http://www.alcohol-injection.com/check-valve-64.html

- All of that is great and all but if you are just installing it for a boost in power/for safety and will not be counting on it, then the basic list above will be fine, can always add the other stuff later as well.

- Another option altogether is to just buy a complete kit to start with, here are some options: http://www.alcohol-injection.com/wat.../universal-19/ Stage 1 kits are just a on/off system, much like the DIY setup i have here and not much point going with those over the DIY really unless you like nice neat packages. The stage 2 is a progressive kit.



So once you have the parts picked out, all you have to do is hook it up.

The picture below shows how i will install mine pretty well and should be plenty for ya'll to figure that out. I am also here for any questions you may have. The electrical is also pretty basic.

The Positive side of the pump will be run to the battery though a 15amp fuse preferably. The ground side of the pump will be run to a relay that is switched by the switch of choice be it WOT switch or the pressure switch.

When the relay turns on it will ground out the pump thus turning it on and injecting the water/meth. when the switch turns off the relay turns off and it stops injecting. You can also wire up an manual switch if you want as well.

The Status LED will be wired in similarly, the positive side will be run to 12+ and the ground side either ran to the same relay as the pump, so when the pump gets power the LED does as well. Or if you got the high pressure switch you will run the ground wire from the LED to that and then the other side of that switch to ground, so when that switch sees pressure, the LED turns on, letting you know that you have meth flowing.

If you also got the low fluid level switch, you will need another LED (i would get a Red one) and wire it up the same way as the first LED, only running to the low level switch this time. So when that LED comes on you know it is time to fill up.

If you can install a radio or off-road lights you can install a water/meth kit. There is nothing complicated at all and can easily be done for under $150, $100 if you already have a wire/electrical connectors/relays ect laying around.

If you have any questions feel free to post them and i will do my best to help you out.
here are some pics i found

I have been looking into it for my NA, doing a lot of research and I can see that it can have some benefits. I have no nitrous, though. I am in NC and it stays in the 90's+ for many months. Even with just water timing wont get pulled due to heat and when in the combustion chamber the steam can help with torque (not hp). Plus, you may be able to add a little timing. With 50/50 water/meth the octane increase can allow you to add more aggressive timing. From what I've read it can give you 110+ oct with 93 in the tank. Boosted applications benefit much more than NA, but if you want to spend the money it may give you some pleasing benefits. I may start putting mine together over the next few months and am going for a trunk mount version with water only.
