    Meth in Airbox

    Ok guys i usually keep my dumb ideas to myself but i'm ready to move on this one so i'd like some feed back.

    my car is a 535xi fbo dci's and before anyone posted about cpe and ER intercoolers on the 535 i had a custom unit made although better that stock it's still not the greatest. Ive gotten by with map3 ww kit. but on hot days map 5 is outta of the question. i dynoed cobb stg2 with poor results and 160 iat's in the spring. map3 dynos fall in line hp wise.

    So I'm thinking about upgraded turbos and being able to run other maps and i already have a aquamist kit waiting and i've read here: http://www.alcoholinjectionsystems.c...icle_info.html

    pre turbo meth is a good idea so my plan was 3 nozzles aquamist says at least 2 i'd locate a third in the airbox post filter, and add a mr.5 setup to insure good flow.

    Buying a new i/c really isn't an option.

    Meth in airbox should lower PWM but won't do as much to cool your IATs as meth post IC. That is how I understand it anyway.

    I considered this a lot as well. if "I" were to do it. i think i would try a 5/7 split, 5 in airbox, 7 post FMIC and go from there, would also consider i high meth content to ensure max atomization/evap for pre-turbo shot

    Why? Doesn't CPE have a good option?

    are you saying 7 nozzles? and thanks for the input.

    well stick heres the deal, 535 guys that log and tinker a bit are hard to come buy so the guys that do have them have cpe/er setups arent really posting up useful data. im not spending another $1000 and front end mods to fit it only to find out its the same as my current setup.

    And id prefer to run my stock air box. basically i have all i need to run safely now, even on upgraded turbos . cpe maybe an option if i could pick one up on the cheap.

    When it comes to 535 intercooler options I think this forum has it covered pretty well. Not a robust subject due to the lack of options but I think you can top the IC you have.

    O gotcha lol. well I'm thinking that theres no real way to ensure equal distribution to the turbos... anyone see that as a legitimate concern?

    yes stick BB has the most info on 535 i/c's i was there when it happened, i had mine installed and tested before it happened. I may be able to top it with the cpe but i wouldnt know b/c theres no proof and contray to popular belief 335's and 535's are vastly different in some aspects especially in this area..

    They definitely are different but if you don't want to explore the IC then meth is logical.

    I'm a bit unfamiliar with Meth on cars other than mine so I may be totally wrong here and feel free to let me know that. However from my understanding spraying pre-turbo would lead the meth to go through the FMIC right? at this point wouldn't the FMIC act almost as a front mount "warmer" since the air blowing against the FMIC may be warmer than the air that's already been sprayed with meth going through it? With spraying into the airbox, wouldn't you worry about messing up your MAF sensor since Meth can be pretty corrosive?

    I would say just spraying as much as you can post-FMIC would be ideal, unless you have an electronic TB that is known to fail if too much meth is sprayed and not evaporated well enough prior to passing through the TB, like the VW TSI engines =/.

    We have electronic throttle, and no reported throttle failures caused by water/meth sprayed post IC. Also no MAF, just load calculated from two MAP sensors, one 2.5bar absolute pre throttle and one 0.25bar absolute inside the manifold (for sensitive idle and low throttle load measurement).

    From what I've read here you want water pre-turbo and meth post-IC.

    Spraying pre-turbo helps to stretch out the turbos efficiency and spraying post turbo is where you're going to be seeing the CAT reduction.

    Me personally, I would place a small nozzle in each intake tube immediately post air box and then two "normal" size nozzles post IC but as far from the TMAP as possible. Using a high meth concentration(~75%.)

    If you are shooting meth or water pre-turbo, you want to make sure your components are top-notch and that you check the spray pattern frequently. I've seen a lot of damaged turbines from little droplets of water hitting the wheel.
    From all the things I've lost,
    I miss my mind the most!

    Correction to my post above: Not a 0.25bar absolute - it's a 1.25 bar absolute pressure sensor inside the manifold.

    And I'm not familiar enough with water/meth injection theory and practice to mess with anything pre-turbo. I'm sticking with water/meth mix post IC only.

    That's why I recommended IMMEDIATELY post air box, small nozzles and high meth concentration.

    You guys are crazy with your 32 nozzle setups. One well placed nozzle (or maybe two if you need a lot, but want better atomization) is all you need. Injecting in the airbox will probably just cause puddling, as the air velocity is very low in the airbox (as compared to the charge pipe).

    FWIW I plan to test this on the RBs just for kicks. Probably dual 3s or 5s in the cone filters.

    I plan on buying a kit from you after I get a new clutch to do this with dual CM5 in the cone filters. Tired of dealing with E85 lean outs.

    I won't be running any post IC I think (doing this to lower WGDC as well).

    Well maybe this wasn't such a dumb idea.. This is happening for me I'll be drilling the airbox this week. @Terry I'm really interested in what you have planned.Thanks guys

    anyone doing direct port for fueling benefits? I think I seen that one guy who was going to go ST do it, but not sure if he put it on yet.

    It's popular on other platforms and could work but I have not seen any hard N54 data on it yet.

    yeah i have a spare intake manifold and all the needed items to get it set up on my VW, just putting off the install. But then again my TB is pretty prone to frying due to too much meth so we should only flow about 250cc/c on stock turbos so pre-tb spraying is pretty much just for lower IATs. I guess it's a bit different with the N54 engine
