Meth nozzle size for Post TB

[jerseybrian]

Wondering what size nozzles other people are using with their TB adapter plates.

I was using a DO5 nozzle pre TB with a REVO 2+ for quite some time, but I'm switching setups (not tunes as of yet) and wondered if the pre/post location would make a difference.

Thanks!

I'm currently running a dual nozzle setup and am running a DO4 nozzle post FMIC and a DO2 nozzle post TB with the INA Engineering (now iABED industries) TB plate.

Pmmember aluthman. he has a killer meth kit . He can advise you what works

Lol. Wait until aluthman responds ok ;)

Same exact setup here. Been working on setting up the post tb stage and think I'm close. Was experiencing some misfires after easing out of the pedal on a gentle pull but otherwise working great.

I could have sworn someone (of substance lol) posted that it doesn't matter where the location was, fluid is fluid. But trust me, I've thoroughly read Adam's and other's meth threads, I'm just not going dual injection right now so I was trying to compensate with my one nozzle

[aluthman]

It does make a difference where you inject it. Post FMIC nozzles do more to drop IAT's due to the increased distance/time to evaporate where post-TB nozzles due more to increase your effective octane rating since it will still be primarily liquid when entering the combustion chamber.

That is how I understood it, but I thought I read someone from Snow Performance stating what I wrote in another forum/thread....

At least I agreed with ya! lol.

I'm currently using a DO2 post Intercooler and a DO1 post TB, running the jhm stage 2 93 file. Its working great for me but I feel like there's "more left in it". I'm planning on moving the DO2 nozzle to the TB and installing a DO3 post Intercooler this weekend or next. Will report back with results then. The kit to run a second nozzle is like 20 bucks and a TB plate is like 80 bucks, well worth it, you'll feel the difference.

Looking for more info here aswell. I spoke to snow they had suggested a 375ml (5) and 175ml (3) nozzles. Hooked up to the "upgraded solenoid" and the stage 3 controller I bought it claims the nozzle are "higher output". So I'm sure that's just a bunch of sales gimmick stuff to up sales. But if so it would seem kinda close to the D02 (330ml?)/D04 (440ml?) if by chance this solinoid somehow increased output.

Side note I have 2 pumps, snow (in hand came w kit) 220psi and a Devils pump (in mail) 300psi. Is it safe to use Devils pump w the snow controller? Will it be much noticeable gains?? Kinda also allows someone here on AZ to pick up my leftovers (tank, pump, post tb spacer)

[jerseybrian]

In a perfect world, my final setup would be an IE intake mani with direct port meth injection to each runner along with the post TB tap. BUT that would be with a custom tune to actually utilize the meth more aggressively. I saw a guy from NY with that setup on his 2.0 TSI Golf R and he was running an aquamist kit iirc..

I'm using a VAST kit which is just a re-branded Devil's Own progressive controller with their 220psi pump from like 5 years ago lol.

I've read your thread multiple times as well jonjon ;) and yes, it's very tempting, but it's also a PITA to take that pipe out, find a tig welder, etc etc..when it's your daily... The post TB spacer is so convenient to install in a quick sesh if you already have a meth setup installed (and yes, I know a dual nozzle is only one more step LOL)

[jerseybrian]

Are these values still accurate for the Devil's Own nozzles?

http://www.alcohol-injection.com/for...ll=1#post12583

It says on their website that a DO2 nozzle is a 350ml/min nozzle and that doesn't jive with the values in the table... Unless they've updated their website to reflect the higher pump psi output?? ya think?

The number associated with DO nozzles is the flow rate in GPH and a set pressure (not sure what it is). I do remember their ml/min not jiving with the GPH ratings on some of them though. Do the math yourself and you'll find that some of the ml/min ratings are off.

[aluthman]

I also sent that meth tubing out. You should see it soon.

Exactly, if that's the case then a DO2 nozzle (2 GPH) only flows 126 ml/min which is less than both of their stated values (on their website as well as their forum post). But that's also at 200psi I assume and some of these pumps are 220, 250, 300.... idk... LOL.

Awesome bro, much appreciated!!! I am going to try using this 225ml/min snow performance nozzle I have laying around with a Devil's Own straight fitting. My concern is that the SP nozzle is longer than a DO nozzle and it might not fit in the fitting correctly. I guess we'll see! hahaha

were you ever running a DO2 nozzle post TB without compensating for it? (i.e. no change in tune)

I tuned the meth controller prior to doing any tune adjustments. It will run fine without changing the tune, but you will see large changes in your fuel trims while spraying. IIRC, you need to remove the filter in order to use the Snow nozzle on a DO fitting due to the length.

Thanks Ad, if anything I'll tweak my REVO tune a tiny bit after I get this setup running with my SPS switch and some VAGCOM logs

Do you have more info on this setup? I am talking with my tuner about doing that but would be curious to see what hardware ( nozzles, pump, lines, solenoid, etc) was used. Thanks.

Anyone see that JHM now sells the Meth kit. https://jhmotorsports.com/shop/catal...0t-p-3399.html

Going with Direct Port injection, I would definitely use some type of Safe injection module like SP sells since I assume you would most certainly be utilizing the meth in your tune. That being said, you would need a lot of dyno time to get the car tuned right especially since I haven't heard of many B7 owners with an IE intake manifold. As for hardware, it all depends on what brands/companies you'd want to use. The IE intake mani already has threaded holes in each runner for meth installation so that's already taken care of for you.

Pretty much the exact same setup that VAST used to sell, just re-badged.

[aluthman]

As a general rule, I've found that the Devil's Own stuff is of higher quality than Snow for anyone that may be wondering. The only Snow part that I ended up using from the stage 2 kit I bought was the controller. I replaced everything else. I did use the pump it came with also, but the pumps are pretty much the same with all the kits so it's not a Snow part. IIRC, they are made by Sureflo.

correct. do both of your nozzles spray at the same time/psi? or do you have a snazzy setup like jonjon ;)

[aluthman]

Yes, they spray at the same time and more or less the same pressure. There is a check valve on the FMIC nozzle that knocks it down by about 8 psi, but it's close enough to the same.

So you have a check valve on the post FMIC nozzle and a solenoid on the post TB nozzle?

And as you can tell, I've been cleaning out my dad's garage and low and behold, I found a brand new check valve and a dual nozzle fitting!! :) Now I just need to order some new nozzles and one fitting from Devil's Own and a solenoid.

How does the check valve lower the pressure of the nozzle?

Here's a basic diagram of my setup:


The solenoid is common to both nozzles. The check valve next to the FMIC nozzle prevents manifold vacuum from sucking the line dry between the two nozzles when not spraying. The solenoid prevents siphoning from the tank. The check valve decreases pressure to the FMIC nozzle because it has about an 8 psi crack pressure that the pump has to overcome to get through. There is also some flow restriction due to it not being an open flowpath.

Ahhh ok ok, I just finished reading jonjon's thread again and I forgot he was using 2 solenoids which got me all fuzzy
