Hey fellas, I have the Conductors Special with the 5 gallon tank, but my pressure switch went bad. While checking the site for a new switch I saw the Shocker S4 1/2" line upgrade. Is it worth it? Or should I just stick with the 3/8" line that I’m running now?
Thanks
I think the 1/2" means more airflow to the horns making them a good bit louder…am I right?
Yeah, I would be increasing the volume going to the horns, but the size/volume increase should affect the tone of the horn as well as the dBs. Im just wondering if its worth the 75 buckaroos…
If anything the tone would be about the same since they are hand tuned. Not sure about the dbs…i’m not an expert. I think they would sound better.
Anybody else?
It’s worth it… I did it and I love it!!!
1/2" upgrade FTW! Do it!
1/2 airline and valve will def make a difference… as will changing the psi…
Is the tone deeper now?
Im thinking about putting together my own 1/2" line kit but im having trouble finding a 1/2" 4 port manifold with a 1/2" inlet.
Also does the hornblasters kit run 1/2" lines all the way to the horns 1/8" inlet??
I just ordered my 1/2 line upgrade! Should be in this week, How much of a diffrence is switching from the 3/8- 1/2 line. I am also running 150psi.
When you find out…let me know. 
I’m still trying to figure out which fittings to use for the 1/2"ID rubber hose…Push-Lock or compression style
Here is the Push-Lock. These are what I use on my truck for my 1/2" Fuel lines…
But I’m not sure how it would with stand to 150+ psi… I know once there on, you can’t pull them off.
Are there any other style fittings that yall are using?
For rubber hose there are also regular barbs with several kinds of clamps.
For DOT tubing there are fittings called push-to-connect or PTC.
Thanks! EDIT: Fastenal carries the PTC fittings your talking about, standard barbed fittings and the Push-Lok fittings like I listed. Im gonna go with the Push-Lok fitting I do believe. They are simple and look good when its all put together.
I found a 1/2" to 1/8" bushing, so all I need is a 4 port 1/2" manifold with a 1/2" inlet and I can run 1/2" hose all the way to the horns.
Has any one done this??
Get PTC… They are awesome and easy to work with.
The Shockers use 5/16" OD tubing for the individual horns.
That is maybe a little over 3/16" ID.
1/2" ID hose is 7x more area - way overkill IMO.
If you want to continue with all rubber air hose, maybe upgrade to 1/4" ID.
McMaster Carr has air manifolds.
Yeah, I can see where you are coming from about overkill. :o I’ll just run 1/2" from the tank to the 1/2" air vavle, then the 5/16 to the horns. I’ll upgrade to 1/2" from the air valve to the horns when I find a good deal on some K5LA’s…
FASTENAL is the best place ever!!! They have anything and everything for the train horn guy. Manifolds, fittings(pust to connect, Barbed, Push-Lock), tube, hose…everything.
Im gonna redo my entire setup from how everything is mounted in my tool box down to the hose…I’ll snap a few pics of before, during and after if yall would like to see my setup.
Im going to run 1/2" ID hose from the tank to a SMC 1/2" 16mm orifice Air Valve to a 1/2" inlet manifold with 4 3/8" outlets and run 1/4" hose to the horns. I’m going to keep the length of the hose between the AirValve and horns as short as possible.
How does that setup sound for the Shocker S4???
Sounds like a great plan. And try to keep the 1/4" hoses the same length.
What did they have for hose clamps?
Sweet thanks.
I’ve been looking for t-bolt clamps and nobody has a size below like 1 3/8".
Fastenal has em - thanks.
