Ok I know there are prolly answers some wwherebut I just got a few. First, safe for daily driving? Second, is it actually safe in general in terms of reliability? And what's the best kit?

 

Ok... here are a few answers

1.) Yes... use mine for daily driving - actually you probably won't go through much meth just doing daily driving
2.) Yes... period
3.) You can use just about any kit on the market - they are sort of generic in that manner. It is all in what the read to control the meth flow.... I use snow performance. There is also devil's own and a couple of others.... go with a trunk mount system....

 

^ X2.

I love the meth on my truck. It helps out alot with towing. When the IATs get hi I turn it on. I usually don't use much at all while just driving around. Meth really helps when you are trying to run extra boost since it cools down the air charge, helps resist knock, and helps with a complete burn. I am definitely going with meth after I turbo swap next year. You will definitely need a tune with the kit.

 

ok well what size nozzle and i am already tuned by vince but my **** is running rich so i plan to get re logged when i get time anyways. so i will just put the meth on then. and i really wanna see someones setup in person. anyone live close to 43103?

 

Depending on the kit you buy, it should include nozzles. I prefer to have multiple small nozzles at a higher pressure rather than fewer larger diameter nozzles. The higher pressure nozzles atomize the water in the air better so it doesn't condense and coagulate in the charge pipe or throttle body. Just something to consider. The snow kit can be found here. I only put that because I used their stage 3 for my truck. It works well and is very reliable, I have had no issues with it. I'm not advocating that one but its just an option. That is the one that I'm going to go with unless they have something better by next year.

 

Ok now my next ? Is, does that kit include everything I need? And could I mount it in the engine bay bc I don't want it in my trunk. And I am not sure where the nozzle exactly goes. I think its some where in the chargw pippingbut not sure. And do i need aftermarket cp on the lower side. I have hot side but not the lower. Sorry for all the ?s but I'm a noob to meth injection and I don't want to fuuuck anything up by faulty installation.

 

Bump

 

most kits include everything. i have aems kit. they say not to mount the pump in the engine bay. duno y. ppl do all the time. installed my nozzle in the lower charge pipe 6 inch before the throttle body. u dont NEED after market pipes...i did thought. if u click my cardomain link in my sig i have pix of my install on page 4 i believe

 

also AEMs kit comes w.a controller so the meth only pumps when above a certain psi

 

how often could the nuzzels clug or something? i was looking into it but then people started telling me that its a gamble cuz you wont know when the nozzel clug...

 

^^^^^I would like to know that to. This whole thing sketches me out. It just seems like so much could go wrong lol

 

the only time i've ever heard of a nozzle some what clogging is when people add food coloring to the meth so they can see their level. Even then...I haven't heard anything bad. They come with filters that can be cleaned and/or changed out

 

snow stage 2 duel nozzle progressive here on my V8 **** works wonders

 

Ok... here is a little more info

1.) Nozzle size - that depends on what you have done to your car and where your tune is sitting. In my case I am fully bolted with a KO4+ turbo so I ended up going with a 225 ml/min nozzle. If you are not as modified, you will probably want to start at a 175 ml/min. You tuner (aka Vince) will be able to tell if there is knock on the low end once you dial in your start and full on. If there is knock on the low end then you insert a higher nozzle.

2.) The hardest thing about a meth kit is dialing in the start and full on. Once again it depends on the car, mods, and kit itself. It is highly recommended you start at 5 psi and go full on around 15 which in our cars is a little tricky since they spool so fast. If you decide to run a snow kit then you are working off of the MAF Hz which makes it more tricky. In my case the aggressive mode ended up being almost an 'instant on' situation - but I can regulate it a little better in the conservative tune. Also keep in mind that for the snow kit, since you are working with the MAF Hz, at higher speeds (highway) you will tend to trigger your meth much sooner (your MAF Hz naturally run higher at higher speeds). I think around 80 mph I can trigger my meth around 3 psi.

3.) Does everything come with the kit? Well once again it depends on the kit. Usually you get everything for a basic install (controller, pump, reservoir, etc.) and then you buy 'add ons' from there. However, you do get what you pay for. For example Aquamist tends to run about $700 for a kit but you get everything. Whereas my snow kit only cost about $400 but then I needed to purchase the gauge and a solenoid. So on the one hand you pay more for the initial kit but don't have much in the way of customization and on the other you can customize your setup completely but it is a pita to figure out everything you need.

4.) Nozzles. Here there isn't too much to worry about. As long as you keep your meth clean and don't install you nozzle backwards you should be fine. Nozzles come with filters on them to prevent particulate from getting through, but they don't build up. If you are getting a clogged nozzle then chances are your meth is dirty or you have bigger problems with things flaking off in your lines. One thing to keep in mind is nozzle placement. You will want to put the injection point in the cold side of your charge piping near the throttle body. They make special bungs that allow you to tap into plastic, but for this I do recommend changing the cold side piping out (metal just made things easier and it seems to hold up better.)

One thing I recommend - get a safety shutoff. Snow makes a safe inject that I like (one of the reasons I went with them). You can probably get by without a low level indicator - believe it or not - but the emergency safety shut off is a must. You should also get a gauge.

Meth isn't as scary as some people make it out. Most times problems arise when tuners decide to set up a car that is running meth on the edge - simply because meth gives you a margin that you can push the car to. In fact you do not have to tune for meth. The thing is that you don't get any octane boost unless you tune for it. Instead all you get is the cooling effect.

Installing meth isn't necessarily a quick job (especially if you want a clean install). Your engine bay is cramped, leaving you only the fender well. You will need to remove your bumper. Dialing in takes a bit of patience and time as well. Then you get to tune for it which takes a while.

Do I recommend it - yes, but only for certain cars. If you plan on going bigger turbo then this is something that you will want to invest in. Otherwise you aren't necessarily going to get the hp gains that would make the time, hassle, and expenditure worth it (some people will probably argue this point though). I think all told my meth only gave me 15-20 more horsepower.

Oh and if you are going to go meth - make sure you look into getting a good meth source first. Some people like to use doctored windshield washer fluid. That was a little sketchy for me so I ended up buying a 55 gal drum. You will go through a lot of meth initially when you are dialing in your car and figuring out your nozzles.
