Devil's Own Methanol Injection Kit - Single Nozzle?

[Zero Tolerance]

Can somebody familiar with methanol injection tell me the advantages and disadvantages between double and single nozzle? I'm about to have my system installed and the installer just let me know I have a single nozzle setup. Maybe I should just buy another system. Let me know.

Thanks in advance.

Triple nozzle for your setup!

[Zero Tolerance]

Is this something I can get from Devil's Own or do I need to go order an Aquamist system? I see I can get a "double" nozzle upgrade from Devil's Own but tripple? Really? Or is that some kind of sick joke? :p

[aysix]

I made a similar thread, but for an aquamist setup. A couple people including max@034 told me to do a triple nozzle setup.

[Zero Tolerance]

Okay. For now, I'm going to stick with Devil's Own and upgrade to Aquamist in the future. I can get this dual nozzle upgrade:

...and I have to choose nozzles from here - which I could use help with:

My kit came with a "7" and a "3" but I'll just buy two new ones if I need to. Any help would be greatly appreciated.

edit: The dual nozzle kit has been ordered (without additional nozzles) and will arrive at J-Spec tomorrow.

Where is the nozzle located?

Dual nozzles are usually placed in the up-pipes near the IC outlets, so you have one on either side. If you have a single nozzle placed close to the TBB, where the two airflows merge you'd just need to make sure you get enough liquid sprayed with the one nozzle.

Thank you. I'm finding out right now.

Ive heard varying debates on the distance a nozzle needs to be from the throttle body and from the valves. Usually people do a twin nozzle setup to get the injection to be 6 inches away from the throttle body, this is impossible with a single nozzle.

I got my kit from Josh @ J-Fonz that only came with one nozzle. I spoke with Pat from Coolingmist about getting the splitter and an extra nozzle, as most people here run two nozzles. He told me straight up that two are completely unnecessary, as he's done testing on both setups, and results showed no difference between the two except for cost. He turned down a sale that I was easily ready to make.

Does he know how the intake paths are for the s4? some people dont know we have 2 pipes, and might be just talking about nozzle size. :P

[Zero Tolerance]

Alright. When all is said and done, my installer won't be ready to get this done until tomorrow and the dual nozzle setup will be there by then. So I might as well just have the dual nozzles handling the methanol injection. No big deal. I don't quite understand the reasoning behind Devil's Own sending me one 3 GPH and one 7 GPH but I suppose there's a good reason.

If you were using a single nozzle it would allow you to somewhat adjust the fluid to fuel ratio.

[AudiSportB5S4]

I have quadruple nozzles.

[MikeyB3]

I have quadruple nozzles.

Srsly? Did you max out the pump? ... or are you just messing with me

Where do you put the three nozzles?

In his funnel.

You realize that most of the lines and fittings they send you are standard irrigation equipment? Just buy a 1/4" quick connect tee and split the main line off into two. Run these into your bi-pipes and be done with it. If you want a nicer setup you can use AN fittings and stainless steel lines but you need some knowledge about the fitting sizes to do it without getting ripped off.

You don't need to buy another system because you only have one nozzle, those pumps usually do 150-200 psi, plenty for 2+ nozzles.

This is only for Aquamist. Aquamist uses smaller nozzles, which helps resolution and control over flow better. Running 3 smaller nozzles is easier to fine-tune compared to one big nozzle, and helps with atomization.

For Devil's Own, you couldn't even run a single nozzle until recently as they only had up to D07 for quite some time, and I used two of those for GT's and my big single. They simply didn't have a single nozzle big enough. People also run the dual setup because it can be difficult to position a single nozzle before the TB but after the bipipes, although there's no reason you can't just one a single nozzle in one bipipe; everything is mixed in the plenum anyways.

Aquamist's smaller nozzles also allow more fine tuning of the actual peak flow, since you can run 3 different sized nozzles which gives you even more options. Aquamist nozzles also max out pretty low, so a big power car may max out the flow capability of two nozzles on an Aquamist.

We will be offering a "bolt on" AEM meth kit soon with dual nozzles and everything you need specifically for the S4, including a totally plug'n'play harness. No lines to splice or anything. The AEM is similar to the Devil's Own, but with some great extra features.

Dual nozzles just because thats pretty much the only way to set it up on the bi-pipes keeping sufficient distance from the throttle body for the fluid to atomize. Most cars dont have this, they have other reasons for dual nozzles.

+1 for Devils Own, they were really helpful, great customer service. I bought my kit "used" from a friend who never installed it on their Jetta before selling it. I was able to send in the two included nozzles(which werent the sized I needed) and they exchanged them for a pair of matching D03 nozzles, and replaced my check valve and nozzle mounts with the newer style ones for basically free, all I did was pay shipping + the cost of a Wye fitting and second nozzle mount.

How much distance is needed is need to atomize the fluid? I thought it came out of the nozzles atomized.

Lol totally messing. I have dual #7s from DO. I also have their braided line setup, it's purdy. With my ERs, those big nozzles, Piggie's phenolic spacers, my IATs are 5* above ambient during most of my pulls. It's crazy.

Well yes, technically they come out atomized, but they need time to mix with the air. Its debatable exactly where they should be placed. Mine are about 1/2 way down the bipipes. Heres a terrible photo

Guys, am I okay with one "3" and one "7" nozzle? Or do I need them to be the same size?

Get 2 the same size... and size them based on your desired flow/power level.

This is probably a stupid question but is there some sort of chart that specifies sizes based on flow/power level? Otherwise, I really have no idea - and didn't realize I needed to do so much research on this before making my purchases. This appears to be the most complicated part of the build process.

Individual nozzles, approximately... Double it for having two ... :)
250 - 350 RWHP: 175 ml/min nozzle.
350 - 475 RWHP: 375 ml/min nozzle
475 - 600 RWHP 625 ml/min nozzle

[temanuele]

I would try to get two nozzles in the range of 225 ml/min to 375 ml/min each.

[Zero Tolerance]

Thanks, guys. I'll be placing another overnight order in the morning...

[bigern45]

good idea!! just have the one nozzle going into the driver side bi-pipe, and when the different temperatures combine at the throttle body it will create a tornado like twister!! pulling in as much air/methanol as possible!!!

were not in kansas anymore toto!! HOLD ON!!

[4ringAR]

or, if it actually does create a "twister", the turbulance will restrict air flow into the engine

[bigern45]

^^ nope, this one is magic, its.. like the weather.. physics dont apply..

lol.. no doubt... ours didnt even give an "overall winter" outlook this year since they were completely wrong about last year.. and the past 4...

[martin0079]

Why not go for 6 nozzles direct port meth injection

[Zero Tolerance]

Thanks, guys. I'll be placing another overnight order in the morning...

And my second #7 nozzle will be at the shop tomorrow morning. It costed me an arm, leg and a nipple for Saturday delivery. I should have thought of this yesterday.
