air horn or train horns

[CumminsChick]

My understanding is that train horns are illegal, so check your local laws.

if you strip down mosta our trucks the list of whats illegal would prolly be suprising long... . its only illegal if you get caught

My compressor and tank are in my toolbox and my train horns are mounted below the box in the truck bed tucked just in front of the rear wheel hump. Works real well. I didn't want anything under the truck. We have salt issues in Chicago's winter wonderland...



I keep the pressure at 80psi and they are wired in with the stock horns off of a relay in the toolbox. 120psi is too freakin loud... 80 is nice... . Lets people know you mean business without drawing too much attention from the cops...

I finally mounted my K3LA the other day. They fit nicely above the driveshaft and exhaust pipe next to the fuel tank. The air valve is mounted in the center console next to the drink holder. A five gallon tank and an Air Zenith compressor will get mounted somewhere. I can at least "plug in" my truck to my shop compressor and blow the horns at this point.

It looks more cramped in the picture than it actually is. I've got chains/hoses/additives/tools and other stuff in this box and have no problems with any interference with anything in there. Works well for me.

I am now a distributor for a horn manufacturer and Viair compressors.



If anyone needs a set of horns shoot me a line...

You can hide the valve area of the horn handle behind the knee plate. That way you dont have to see the plumbing.

You guys are twisted, lol. Working for the railroad I have to hear those dang things, sometime right above my head. There is no way I would want them on or under the truck.

With the exception of the first week of fun, I never seem to use them anymore.

Since mine are fired by the stock horn, I use em' everyday. One day I disconnected the compressor because I was wiring up some other stuff, and I was out on the road and hit the horn... . and, well... the stock horn just plain doesn't cut it. Seems like I can barely hear it at all... I'm used to the loud stuff now...

I've been thinking of some big air horn's or train horn's, but don't want to use an air tank! I've seen in magazine's the set up that uses a little motor that instantly give's air to the horn's. I had a cheap set from Autozone when I was 18, but those were the cheap plastic horn's that were high pitched. This is the same style, but for big truck horn's. Does anyone have this set up or know if they work on train or semi horn's? I want that deep roar, not a squeek! :-laf

Beach,



It would have to pump an awful lot of air very quick to drive a set of horns big enough to get the sound you want. If that's possible, I'd say it would be pretty expensive. Just my opinion.

While train horns are probably the loudest, the setup, air supply/control is significant, and/or not convenient. Get a couple of used truck horns off ebay (mine are 22" and 24" Freightliners) and that will be plenty. I seriously doubt that you're going to blow your air horns at someone just to get their attention. You can see how I did mine, on my gallery...

My buddy drive's a customized Peterbuilt that he took the original horn's off! He said I could have both for $50. If I got those, what kind of air pressure does it take to blow them? Also how much p. s. i. do train horn's require?

 

[JFaulkner]

Semi's usually run around 120 psi, but the semi horns will blow with alot less. (just not as loud). I've got 2 sets of train horns and it's not so much the pressure but more the volume of air they require. You can use 1/4 inch line to the truck horns, where the train horns I have 5/8 which limits the valves you can use to blow them. (electric solenoid valves that size are expensive, so mechanical valves are your best bet. ) Here's one set of the horns.
