Nozzle Location

[superskaterxes]

so jhershorin gave me an awesome link to an article describing all the +'s and -'s to nozzle placement in various locations.

Where Do I Position My Water Injection Nozzles

i havent decided if im going to go the PTP route and use the freeze plug or do it this way.





i am afraid the nozzle will clog with oil if i use the PTP way but i do agree that its a better location then pre TB. can anyone comment on my idea? will this mess up my BOV?

haha...thanks, mang... ya, i'm with grim: i think you should inject post-BPV. did you want to move it farther up the pipe just so it has time to disperse more before the TB? if so, don't even bother, because it will have PLENTY of time to disperse in the intake mani...=d


btw...you can delete your own posts, so you may as well just delete the posts yourself...i already got rid of mine.

no i moved it so that the nozzle would shoot directly at the TB itself instead of 90 deg to it.

OHHH...ya, that's true...=/

well if your gonna put it on your cold pipe then your gonna want it after the bpv.I still say the freeze plug is an awesome spot.

I was thinking cold pipe as well. I just bought an extra one to stick onto my ETS, that way if I have to return to stock then I can just remove the entire TMIC and nozzle, and put the stocker back on for dealership visits. I may have a machine shop drill and weld on a threaded mount for the nozzle so it points more or less downstream, and not blow directly at the opposite side of the cold pipe.

Ah, the things we do to make things work...

after talking to jordan ive decided to do the freeze plug. theres no way this nozzle is getting clogged.

skater, i posted this on the other site, and just copying here, cause i'm not sure where you hang out most anymore. I'd like you input on these thoughts though:

Just thinking more about this, and i still think either location (CP, or freeze plug) will work fine: I guess the concern is not getting enough w/m into one cylinder and more into the others, right? Well if spraying into the CP, with adequate time (pipe length) for proper atomization, then you can guarantee that all air entering the manifold has, pretty much, equal amounts of w/m. So if there is an imbalance between cylinders, then that same imbalance would exist with air, and you'd have some cylinders running lean, and other's running rich. I don't think this is the case (but who knows). When spraying into the manifold freeze plug, it seems like the direction of intake air would possibly retard injection in the first cylinder, like pissing into the wind, but i'm not 100%. I guess i like the idea of the CP because a). That's how i did it, so it must be superior, haha, and b). you can guarantee that all air entering the manifold has been properly mixed. Actually and thinking back to that ptp video with the injector mounted in the bottom, that was with the mani off the car, and no "breeze". I guess i'd like to see the same test with a compressor or something hooked up to the TB, blowing air like the turbo would be.

cold pipe for me, and his ^ explanation makes sense to me. How well it sprays with the mani off the car I don't think really means much.

Either way in the end maybe it wont make a huge difference either way. Cold pipe is a tried and true way that you know will work just fine

I would not mess with putting it in the freeze plug. Where you are wanting to put it looks fine.

BUH!!!! i might just do my own damm tests cause when PTP does it they arent doing the full scenario!!! god dam back to square one lol

Take pics or vid if you do. I know jmhinkle is on deck for WI, and he has a spare mani, so maybe he'd be willing to do tests as well. I'll ping him about it and see what he says. I'd hate to tap the mani and find out that it actually isn't the optimum feed spot, and have to plug it again.

if someone could lend me an xtra mani i would def do this. but i cant afford the downtime of taking off mine just to test this.

anyone in the NY/NJ/PA area have an extra mani i could borrow?

Its not really showing the whole picture. Its a valid attempt. I am actually the one at DevilsOwn that designed the nozzle being uses. We had to resort to using a supercharger dyno to properly test what is going on intake track. Shop vacs do not have anywhere near the power to replicate what going on in the engine.

if u used a leaf blower u would have plenty of CFM

What about putting it shortly after a FMIC. That way it has a chance fully mix with the air before passing the TB? Wouldn't it help to cool the air after the FMIC more before passing the TB?

read the article in the link of the OP. it has the disadvantages of this exact location.

is that big square thing were the bpv sits?if it is it would get recirced back into the intake then into the turbo,which is bad.I really dont think the nozzle will get clogged up in the freeze plug area,the pressure would just shoot it out if it even was.or you could just get a catch can and not worry about it.

lol yes thats my BOV flange from scratch haha. in my mind what you stated makes sense to me as those were my original thoughts but apparently thats not the case. i need some more input here.

i guess i'm a bit spoiled, because the cobb fmic gives me the clearance to put in that 4"-5" clearance before the TB even if i drill in post-BPV...
