Water/Meth injection

[challenger]

I have been doing a lot of research on this and I am not sure witch kit to get. I am thinking either CTSTurbo or Snow performance. I know CTS uses Snow performance so what is the difference in the kits? I don't know if the throttle pipe in the CTS kit is necessary if you are already running a FMIC but I could be wrong. Also, are there any DIY for this because I cant seem to find anyone that has a thorough install on this for our cars. If anyone is running these kits can you tell me your experiences with it and any problems you ran into if there was any.

The instructions that come with the snow kit (or from their website) were more than sufficient to do the install. Shane did a DIY for a W/M kit which is simply a rebranded kit with some extras thrown in. The CTS kit that you provided the link to also includes a TB spacer with a tap in it, which is not included with the Snow kit and is sold as an option. It also includes the cold side piping which is much easier to tap into without an additional grommet in your stock piping. You don't need the piping if you already have a FMIC, upgraded SMICs or hard piping.

I love the Snow kit I've got. I bought mine from Clay at CTS along with the FMIC. I see IATs within 5-10deg F of ambient while cruising and can see temps 20deg below ambient when on the throttle with the meth spraying. My injector is about 6" from the TB as per Snow's suggestion. I also plan on getting a TB Spacer and doing dual injectors someday too.

EDIT: Oh CTS's also includes the solenoid which is an add-on for the Snow kit.

Methanol injection doesn't work on the FSI engine. We have special programming in the ECU which compensates for the reduction in temperature of the intake air and variations in octane. The secondary intake by-pass valve will open and negate most of the effects. So it only kinda works.

What you need is a surge tank and secondary port injectors.

Isnt that more tune dependent? Ie, APR has different tunes for different octanes which leads me to believe that while there is accommodation in the ECU, there is benefit of W/m as long as you tune for it. Adding to a stock file or stage one file will help with IATs and maintaining timing advance but not account for the increased octane effect and map driven timing advance.

You are one of the ecu gurus so I am interested in learning more, especially if it means w/m is a waste of a mod.

[ericpaulyoung]

I was mostly just bullshitting him. :)

Honestly speaking:
1. If you are not knock limited and not tuning for a knock limited condition, then meth injection is indeed a wasted mod.
2. If you are knock limited or going to a tune that will be, then it is an absolutely great mod.

Don't forget that our valves are sodium filled, which means they will absorb all excess moisture not recognized by the maf and IAT sensors.

I thought the sodium filled valves were just there to season the exhaust flow? You know, so it smells better?

Do you recommend going with the one off CTS then? Also, could i just run one nozzle where the spacer provides it or do i need to locate it further away? or does it not matter.

It is definitely pointless to run without a tune but i plan on getting it tuned after along with my hpfp or should i just wait till stage 3? Also, isn't it good for carbon build up?

It depends on your setup and personal preferences. The further away from the TB, the more cooling effect. The closer to the TB, the more of an octane boost you'll get from it.

Meth will help with carbon buildup, but not completely eliminate it. The stock PCV system it a big reason why FSI engines get carbon buildup in the first place. Without replacing it, you continue to add to the mess.

Maybe ill just go with the dual nozzle set up to get the best of both worlds. I heard it helped some what but id also need to get a catch can to really help with the carbon build up. Was the CTS instructions specifically for the audi a4 b7 or for the vw? Do you have any pictures of the install by any chance?

Again, I actually have the Snow Stage 2 kit, but I did but it from CTS. IIRC, the instructions were for a 2.0T FSI and differentiated when there were differences. i.e. The MAF wire for one is purple and the other it's brown.

Very easy to do. There are only 4 wires to the entire MAF based system. 8 if you count LEDs.

Okay, Great thanks for the info! Definitely going to get it after my bank account is reimbursed from the CTS FMIC.
