It's just a little turbo

[Speeddm]

OO the water meth debate. One vs 6 injectors. I see Leeaspin clearly doesnt understand how ineffective the RB plenum is. Good luck to you sir. If you would like to do it right for an RB take a look.

I would have trimed the lines a little nicer but thats just me. FIX IT S.D.

Holy mess, I would have tapped them from under for a stealthier look, but good idea.

[Speeddm]

So lets say you put them under the manifold. Then you change turbos and need larger jets? Ill let you reconsider you thoughts now.
O and thats an Aquamist HFS-6 system http://www.howertonengineering.com/Aquamist_hfs6.html

[leeaspin]

Which charge pipe is that?

I was thinking about mounting it after the intercooler either right before the plenum (upper charge pipe) or the one right after the intercooler.

I have it on the upper charge pipe about 6-8 inches away from the plenum

put what under the manifold?


....was on the phone didnt see your last comment about the 6 jets

If I was using meth for 100% reliabilty I would use 6 jets...i'm only adding meth for a safety factor...and seeing as how I have not seen or heard of any issues on an RB with this meth I will stick to my one nozzel for now...If you have legit proof of 1 nozzel harming the motor feel free to post it here....dont be a **** about this debate or leave your comments to yourself please...everybody has their own opinion and im going with the recommended requirements for the kit which is 1

Yes 6 jets is safer for sure but i've Know at least 5 rb26 with a single jet mounted where you have it "leeaspin" and no problems so far .

thank you sir!

whatever man. 6 jets is just asking for a problem which will gaurantee one cylinder goes lean if there ever is a nozzle issue (which is 6 times more likely than running 1 nozzle).

furthermore i dislike that picture above because there are zapstraps holding key components to the throttle bracket which looks like bad news waiting to happen. likewise with the 6 nozzles all having different length hose between the distributor and individual nozzles. initial delivery is going to be sporadic until full pressure is achieved. and the hoses are not wrapped so boiling and evaporation could occur and make the equal distribution even worse as boost comes on. i hope that your meth starts spraying very early

countless individuals run 1+ nozzles in the charge pipe and it works as intended. optimal 1-nozzle-install will be between the IC outlet and before the throttle plate. the bigger the nozzle you may want to put it slightly further from the throttle plate to give it time to atomize fully.
the goal here should be to cool the whole intake charge and surrounding area to suppress knock and increase octane for added timing.
if your goal is to supplement your fuel with 115 octane methanol then i do understand 6 jets, 1 per cylinder.

if you blow your motor from having 1 nozzle around 6" away (or where we would otherwise agree to be optimal) from the throttle plate then you likely had another issue at the same time.
i would aim your guns more at the tune, or figure out why this/these cylinders were getting less air than the other ones.
with 1 nozzle, if it fucks up you at least have all cylinders still running equal and perhaps your gauges or your ecu can detect the problem.
such probably will not be the case if 1 of your 6 meth nozzles develops an issue.
thats not what i wanna hear when boosting 24-30psi on pump gas.

for example if more air is reaching the #6 cylinder than the other 5 or whatever combo you dream up then methanol or no methanol you still have more air going to cyl #6..... so if this is the case and nissan released the car with uneven air distribution. then you should address that issue perhaps before ever boosting beyond stock levels.
same thing could easily happen with no methanol injection when you tune near the edge.

i would venture a guess that if lee's car has survived this long, with no signs of detonation or knock (he has a knock meter). then he will continue to boost within the safety margin if he gets his car tuned by a true expert.

you can argue with me all you wish. and i will appreciate facts, not opinion. im not a meth injection wizard. i just read alot. if you argue without facts im going to have to take your opinion with a grain of salt along with the other random dudes off the street that ask me why im running 1 turbo instead of 2. isnt 2 better?


if you wonder where the F i made all this crap up from, its time to do some reading.
here is a good start:

http://www.supraforums.com/forum/showthread.php?t=550320

read that thread if nothing else.

ill dig up some more if needed but i think that will be a good start. running meth injection isnt some new sliced bread. its been around quite some time now.

and dont get me wrong i will agree that 6 nozzles could be optimal. but i hope your meth system inspection is a very frequent task.

keep it simple on a street car. less complexity is less chance of something going horribly wrong.
also this post is a tad longer than i intended and i dont care to proof read it so hopefully it makes some kind of sense.

[edit] just so were clear, if your choosing between 1 or 2/3 nozzles pre TB, or direct port. i suggest you research the subject to the max and develop your own preference.
personally i would never do it to my street car but i probably would for a competition car that gets dissassembled often with strict maintenance.

i read the first 6 pages of that thread and i used to respect mike from AWD more than i do now.

[leeaspin]

Pretty sure this is a skyline forum....in regards to this an evo is not even remotely relevant to this subject.....so what if the post that you showed here in this link has wack stuff all over the piston in cyl #1, obviously a way bigger issue than just meth....its not a nissan and serves no purpose to me in persuation to get me to run 1-6 nozzels...

If this debate goes on there has to be clear and I mean CLEAR information including full documentation on a NISSAN that improper flow has tampered with the motor....and if you wana keep arguing about how many nozzels to run please start your own thread about it in the tech section or discussion session.

Like agm posted if i'm building a competition car that is getting torn apart frequently to be able to see the results and what needs to be changed then maybe I would be running more nozzels....but for now because it is for extra safety there is no reason to have 1 for every cylinder

[DJ]

There is one set up I like from a member on this forum i think its "crzyone"'s gtr they installed two jets under the manifold I belive the first at an angle that will spray to the first 3 cylinders and the second shooting to the last 3

[agm]

sounds shady unless you know the flow characteristics inside the plenum to dictate exact 2 nozzle placement. i'd rather use 6 nozzles in that case.
with it before the TB and after the IC, at least you know its going into suspension with the air charge which is already moving in that direction to all 6 cylinders.

which also cools the IC pipe and whole plenum on its way in. if your not getting meth to a cylinder--you're not getting correct air to that cylinder either so it will be making less power than the other cylinders with meth injection or not.
in which case you might wanna stay away from a dry nitrous system aswell unless you have some EGT probes in each cylinder to get a heads up on the random AFR's in each cylinder.

especially on a oem turbocharged car, i am not naive enough to believe that nissan didnt spend enough R&D on the intake plenum such that it doesnt flow equal to each cylinder....

[Super_Dude]

The point I'm trying to make is that direct port meth is the absolute best way to get even distribution. Anyone who a thing or two about meth will agree. I consulted a lot of meth experts and actually switched from a single nozzle aem setup to the direct port HFS-6. Arguing that there is a reliability issue with 6 jets is silly. It's just a port nothing fancy. If you really believe that switch out your x6 fuel injectors and just get a couple huge ones to improve "reliability".

About the unequal length of the lines, There is only liquid in the lines not gases. When you apply pressure and all the lines are full the all spray at the same time. I even tested this when I installed my kit so that is a mute point. My kit is also PWM (Pulse Width Modulated) which means it acts like an injector not just a pump that increases pressure (HFS-6 FTW)

I'm not saying that running 1 or 2 jets is a bad idea. I'm just saying it's not the best idea. If you want the full benefits of water/meth than direct port is your best option.

Sorry for going of topic.

Anyone who wants to run water/meth should do a lot of home work

http://www.aquamist.co.uk/vbulletin/ is a good place to start.

Super-dude you touched a very important fact in regards to one or 6 injectors. Both kits use a different delivery system. Andrew in running the AEM kit similar to lee's and he runs 2 injectors, 1 per 3 cylinders and he is pushing over 650whp on a mustang dyno with no issues of leaning out or detonating in the rear cylinders. The AEM I would personally say is the inferior meth setup compared to the Aquamist but still works fine. because it runs a variable voltage pump its hard to get accurate delivery of meth each time everytime and if a injector clogs or becomes partially plugged I dont believe it has anything to make the driver aware ? please let me know if it does ? The Aquamist kit like you mentioned above uses pulse width technology so like you said is essentially a water/meth injector so the delivery method is alot more precise.

Lee said he is using it for a safety more then a power additive so Im sure 1 will be fine, my question is if you already have the plenum off - and we all agree that is a c**t of a job - then why not run 2 nozzles like the high hp GTR guys are doing ? its a 20 minute job to drill and tap to nozzles into the plenum then if you need them in the future its done.

Cheers
