I'm thinking about setting up WI for individual runners and the intercooler outlet. Thinking about it, on the plus side there are the benefits of air chilling and also "direct port" water to combat detonation. On the negative side, I think this could be difficult to tune and I'm also not sure how to set it up properly.

I'm thinking a Y splitter with one fork going to the IC and the other going to the IM would work. Fork the IM Y again and then fork the fork for 4 nozzles for the runners. Use same sized .5 nozzles for the runners. Maybe use a .8 nozzle for the IC?

For tuning, I think it might be best to tune both the IC and IM WI separately to get food flow targets, then plug em both up and mess with the maps or the nozzles to get things right.

What do you guys think?

 

Useless...
Dont complicate things more than you have to.

 

Why useless?

 

i know of a couple guys who did individual jets on their MKV GTI.. they saw no diffrence between that and using just a single port. the effort to go about setting up the extra ports was a waste of time.. they said it wouldnt have been a total loss if there was any gain.

i know its not on a miata but they were doing the same thing.

 

Interesting. I want to do individual runner though to make sure each cylinder gets the same amount of water.

 

ya thats what im talking about.. they stuck a nozzle on the under side of the intake manifold in each one of the runner.. ill see if i can dig up some pics

 

cold side of the intercooler should get the cylinders damn near identical, the air is turbulent enough coming out of the IC, and there's plenty of distance before the manifold. A lot of guys aim jets at the throttle plate, and dont have any problems whatsoever

 

im still looking for another set up which showed how he used only T's for distrubiting the meth. but anyway heres one

 

Woahhhh WTF is THAT. I was going to use Ts or Ys but that **** looks much sturdier.

 

You can get distribution manifolds like that from a variety of suppliers. DevilsOwn has a few of their own, which accommodate standard 1/8 NPT fittings: http://www.alcohol-injection.com/dir...ifold-129.html

If you have a drill press and some scrap aluminum bar stock lying around, they're not difficult to make. While you're at it, you can switch from press-in fittings to screw-type compression fittings if you want. Check your local ACE hardware for the fittings- they're the same ones you use to connect icemakers and in-counter filtered water dispensers.

 

Your going to need individual ones. Because one nozzle WILL NOT cool all the cylinders easily. LULZ

 

Thank you! What is your opinion about my original question Joe?

 

??????????????? WTF does this mean? I'm guessing you're being sarcastic and don't know much on the topic?

 

BTW FWIW here's some post I found on an Evo forum straight from Mr Aquamist himself recommending my idea.

If there were a god though, he's not it so I am still interested in hearing other people's opinions.

And here is a post from mr snow performance recommending this also

My opinion is that I had six Mojitos with dinner, and it's a miracle I was able to walk the four blocks back to the hotel, much less log into the forum and post a link to the DO manifold. You don't want to be listening to anything I might have to say about nozzle sizing right now.

 

I don't really understand the idea behind having it in BOTH places.

Just makes no sense to me.

Either do 1 big nozzle or 1 small per cylinder. Why create a clusterfuck of potential failure points?

 

Yeah, that. Pretend I wrote what 18psi wrote, only with big words like "elucidate".

 

For what its worth, I strongly question the notion that evaporative cooling prior to the combustion chamber is the principle method of action of WI insofar as its anti-detonant qualities are concerned. I haven't done any original research on the topic, but a lot of what I've read of the old NACA studies suggests that the presence of water mist in the combustion chamber endzone during the compression cycle is where the real jello's at.

IOW, further away from the chamber inlet != better.

 

1 big nozzle. no need to complicate it... most meth/water setups are all kind of a wild *** guess anyways exactly how much you are spraying.

 

Sarcasm. Branching from arguing with Tom.
