The Snow plastic nozzle holders will burst under boost pressure.
I just lost my boost side Snow nozzle holder to pressure.

 

wow that sucks..im not familiar with the nozzle holders you speak of tho. it should be a 90 degree metal elbow not plastic wtf?

 

Why would they use a plastic part there....wouldn't be my first choice in a kit

 

What part are you talking about, exactly?
The interface between the liquid tube and the metal nozzle?
That doesn't really see any pressure if you have the tube seated correctly.

 

it sounds like hes talking about the 90 degree elbow that holds the injector and attaches to the hose. but i cant belive that snow would make such a shitty part. possibly its the little plastic peice or "quick release" clip on the elbow. but i cant see how that could blow out..

 

That elbow shouldn't see any boost.

It's a plastic 90-degree elbow that accepts the quick-connect high pressure hose and then the metal nozzle screw into the elbow on the other side.
It should see no boost when you're spaying.

Besides, the pump puts out over 175psi (up to 225psi) which is MUCH more than any turbo car would see in the manifold.

I think you either have a faulty install or bad apple.

 

Not to mention that the boost would have to find its way back through the tiny nozzle!

 

still though a plastic elbow?? that's kinda shitty...

 

Well, all of the commercial water/meth kits use a plastic piece as a terminator.
But its not shitty on the AEM or Devil's Own.
I suspect its not shitty on the Snow, either, but I don't have one in hand at the moment.
It is likely that the original poster has a combination of issues that have led to his predicament.

 

what do you mean by terminator? cause the only plastic peice on my cooling mist nozzles are the tiny plastic quick release clips ... the elbow is all metal

 

I forgot about the Cooling Mist.
Yeah, they use a metal "elbow" on their "Stage II" and above kits.
Now that I think about it, so is my AEM. (its not an elbow, though - its straight.)

Now I'm not sure about the Snow kits contents.

OP - pics or it didn't happen!

 

Damn that sucks...And that is why I am putting in an AEM Kit on my car...

 

so far I have no mechanical issues with my Snow kit. It even included the tap for the nozzle!

The only issue is the controller not kicking in at the PSI level I set it at. I set it for 4psi and it wasn't swtiching on until nearly 8! So I kicked it down to 1 on the controller and now it turns on at 3.5psi.

 

yeah im surprised they would use a plastic nozzle holder...a metal elbow is such a cheap piece..i bet they could probably get them for the same price as plastic...its like identical to a plumbing piece except i think its nickel plated.

 

i don't see what the big deal is- the hose is plastic and it works just fine. Up to 300psi.

 

but it gets threaded into the intake tube..im not sure if there the same design as the metal cooling mist ones but i wouldnt want plastic if they are the same design

 

No, the nozzle part is metal.
The coupler is plastic. It just keeps the hose attached to the nozzle.
All of the water pressure is passed directly from the hose to the nozzle.
Conversely, all of the boost pressure gets applied back against the metal nozzle.

 

There is a plastic 90 degree elbow, the hose and all the fittings inside the 90 degree piece blew out.


Yeah, I can't believe it either, I am thinking of another brand of injection now, if I would not have seen it, or if I had been running straight methanol, or nitro

Wow, compare that to "The Devil's Own" nozzle holder.

 

Plastic 90 degree elbow wtf? , just purchased my unit and have it sitting @ the house, will check and confirm that plastic 90 degree elbow again, but last I checked there was no plastic and the whole piece was metal. Only thing plastic was of course the container and bulk heads

 

As a matter of fact there is a quick release type connection on the metal elbow (push on outer ring to release) for the nozzle .... No plastic here...

 

contact snow they have a free upgrade for people who have had problems with this nozzle holder. It is all metal. they told me that they had a bad bunch of holders and they then redesigned.
olddragger

 

I have already ordered new nozzles, holders and check valves from The Devil's Own.
The nice thing about DO is the nozzle size is stamped into the side of the nozzle.

 

damn man, even tho it is cheap plastic and id want metal ones, there is still no reason it should have broken like that..id be trying to figure out what caused that to break...how old are they?

 

Fixed

Here's a better comparison of the snow nozzle holder...

and as you can see there's even a quick release type connection for the hose..quality stuff here

 

It still shouldn't break. The bulkheads on the pump are plastic. So is the hose.

If Snow is giving them out as upgrades I'll get a freebie but otherwise plastic is no big deal
