If you can think it up he can laser etch it. The rockers are only $5 and the switches range from $10-15. They are very high quality switches and worth the money.
Got’em in!!!

Awesome looking horns
Got done around an hour ago. Those last two hose bracket kicked my a$$. Here some pics and a video going through the Harvey tunnel.

Great install! Did you use the ball valve?
Love the video - sounds like all heell is breaking loose!
Yep. You can hear it in the video if you listen. That whole tunnel exhausted all but 25 psi out of 10 gallons:eek:

I think I might need some kind of check valve on the low side. When I honk, it sounds like its bleeding off. I think what’s happening is the low side is getting pressurized through the T and when I let off it bleeds back to the horn at a lower volume because of the ball valve. If I put a check valve there then it can’t get pressurize in the first place, thus quicker on/off on the high side.

That’s some pretty big hose and a decent amount of volume to get rid of - especially with 2 lines.
Couple things you can do… You can bring them back to a single line after the valves. and/or Move that whole assembly a lot closer to the horn. Basically reduce the volume between the valves and the horn.
I wondered about check valves on mine too, but didn’t know how to size the dang things.
That’s why I was saying to put a check valve at the T by the horn, then it would be like it had only one line running to it. The bleed off ( or whatever you call it) isn’t bad at all just trying to fine tune it. I know this, if I did put a GW in the cab and had the horn where it is now (about 16ft of hose) it would be way worse. The distance from the valves to the horns now is 5ft, so I don’t think that is playing a big part of it. I might do two check valves if I can find one that will flow enough for the high side like a 1/2 NPT 5/8 orfice.
On a side note, I’ve been playing with these all day long. Its so much fun honking at your customers as you pass them by and then they call you and say they like the new edition. One of them what’s me to sneak in their yard and wake this guy up that always goes to sleep.

What is the ID of that hose?
5/8†the id on the push fitting is 9/16â€
Sent while gathering Allison parts.
That is 3x the cross sectional area of the plain ol’ 1/2" DOT.
So your 10+ft of hose holds about equal volume to 30ft of 1/2" DOT.
Just saying - it helps to have the valve as close to the horn as possible within reason. And the reason is to combat exactly what you are experiencing.
Just trying to help…
I know you trying to help that’s the reason why we’re on this forum.
That is the closest I could put the valves to the horn without putting them on the horn.
I’m going to close the ball valve and see if that solves my problem that will tell me if a check valve will work.

That’s a really good quality install. It shows you’ve taken your time with it. Very nice! Just had a look at the vid and you gotta be happy with that performance. Once you get your dual line issue sorted that thing will be deadly - then again, what am I saying… IT IS deadly.
Looking forward to more footage.
Closed it off and it definitely comes on and off quicker. Here’s a video. Sorry for the back ground noise, it’s the dudes phone going off. That’s ok because when I hit the horns LIKE A BOSS you can’t even hear his phone and I’m about 100 yrds away.

What can I record it with that won’t distort like that?
Sent while gathering Allison parts.
Well that sure seems to have done the trick. You going to try and put in the check valve?
If you’re recording on the phone, try downloading a recording app that lets you set the mike sensitivity (i.e audio levels).
Most cameras with video recording work well. The problem with phones is the pick up microphone is so small it distorts the sound. For instance I have an older cannon camera and it works very well but not at night. All the newer cameras or most of them are HD so you get the best of both sound and video.
Rex.....Yep as so as I find out where to get one. I’m gonna call Grainger in the morning and see what they have. I stopped at the local hydro place and they have a Parker that flows something like 160cfm at 100psi, but they want $35 a peice:eek:
Doesn’t the GW flow only 90cfm?
Sent while gathering Allison parts.
Yeah, wow… just goes to show how cheap you guys get everything in the States. Over here that price would undoubtedly be a steal for a single Parker valve. I’ve had to pay that much for some push fit combos.
By the way have you ever put an in-line flow meter on the horns? I guess you have big lines leading to the manifold, but seeing it’s on your low pressure bypass side I wonder if they actually flow that much at a 100psi. Have to remember, you’re still restricted by the throat on the intake of the horns, which is very small.
