Not quite. Orifice size (which is the internal passage in the valve chamber) will be a factor. Orifice size decreases with the ability of the solenoid to handle larger pressures. In your case, you’ll obviously want nothing smaller than 12mm to match the inlet/outlet ports, but slightly bigger is better.
This one is a top choice.
Done! Bought! Ordered!
Whohoo :). Make sure you take lots of happy snaps when you do your install. That’s gonna be one scary bug!
Yes I know
Thanks for inputs…
Everything is going to be delayed because everything will be sent down here to south america Colombia!
Manual says to use a buffer tank
7. On extreme long runs, a buffer tank, located close to the horn, will compensate excessive pressure
drop. Pressure drop at the horn, should not exceed 15 psig (1 bar), when blowing. Install test gauge
at the horn inlet to check this when installing.

So how did you end up doing your install? Post some pics and details if you can because if that’s a K3, then something isn’t working out properly and you’re not getting anywhere near enough air through the horns.
Ok, that’s what I needed to hear.
They are installed directly to the oem manifold, using a 16mm ID hose.
At 90 psi, with an output restriction at the regulator of 1/4.
They are blown to the right side of the car.
I have installed the the on separate brackets under the car using this thread
But changing from
Quick Fit Elbows with a threaded end. I used 5/16 QF to 1/4" NPT instead of 5/16 QF to 1/8" npt
http://www.trainhornforums.com/showthread.php?t=5734
I will now drill through the first 3 QF couplers (right on the + manifold) because there is some restriction where the 5/16 hose stops, so there is a bottle neck there.
I have also ordered a fixed 150 psi regulator for the CO2 tank.
I’ll try to get someone to help me with the video, and after drilling the couplers, I hope it improoves!
Don’t overly focus on small point restrictions. For example you would’ve seen that the intake throat on the Airchime is really small (only a few millimetres). It’s the distance the air as to flow through the restriction which is where issues start to occur.
Air flow restriction will really bite you when you run through narrow line over a longer distance. If you’re running 5/16 line directly to each horn, make sure it’s really short, otherwise switch to 1/2 air line and fittings.
When I initially wrote the thread about the mounting blocks, I used probably around 2 feet of 5/16" air line. I’ve since remade them using 1/4" NPT to 1/2" QF. You can hear the difference if you look at my videos (e.g. the “Shocker vs. K3” is the 5/16" line and the “underpass” video is the 1/2" line. ). It’s not really a huge difference, but you can hear it. Even on the smaller line though it didn’t sound like your though.
I think in your case, there must be some other issues and I suspect it could be right up at CO2 outlet. What do you have attached on the bottle outlet? If it’s an adjustable CO2 regulator, perhaps try upping the outlet pressure a bit.
1/4" output at the regulator and set to 160 psi to 3/4" hose and 3/4 manual valve, then 3/4" hose to a + manifold, then 1/4 npt to 5/16(x3) and 3 3ft 5/16 hoses to the bracket blocks.
The regulator froze, and then it wouldn’t work properly.
I took it apart and cleaned it, and now it works better, but all I can feel is that they start loud, and after 1/2 second after there is restriction.
I’ll wait for the poly performance 150 fixed regulator to get to me (15 days probably) and just change that, make another video to compare.
Meanwhile, any inputs are appreciated!
Freezing is always a challenge with high pressure gas. Part of the reason why the regulators are specifically designed for different gas applications. Take your 5/16" lines out of the horns and then pull the trigger… are you getting any dry ice particles flying out of the tubes? If you’re getting buildup of ice in the air stream then they’ll plug the intakes on the airchime. There’s mesh filters to trap that sort of stuff if that’s the issue.
Did you get any flow rate specifications from Poly Performance? I thought those regulators are more suited just for tire inflation. With the K3 you’ll want about 80CFM flow out of the regulator.
That’s the best I found!
But if you can find any better, it would be great!
Just another quick thought… not sure how you have your bottle mounted, but make sure you’re not having it lying on its side (stand it up), so you don’t have liquid coming out of the bottle which freezes up your regulator.
ouch, my tank is laying on the side…
Where did you find this info? this is new to me…
What is the least angle it can be used?
although, do you think a 3 seccond honk will freeze the regulator?
Ages ago I had a home brew setup which used CO2 bottle. I remembered being told then never to lay it on its side to avoid problems with the regulator. Makes sense I suppose. Keep the liquid level below the valve so you only get gas coming through.
Apparently you can get an anti-syphon tube (or tank) which allows CO2 tanks to lay on their side. Basically a metal straw which extends into the tank and then arcs up to one side. Obviously the bottle would need to be turned so the tube points up.
ohhhhh, I’ll try some leaning angles to see if there is a difference
