Cool Charles, what kind of horn did you get?
</div></BLOCKQUOTE>

I found the manufacturer of this horn setup in China. The horn was rated for 100 PSI.

I talked to them real nice, agreed to buy 3 cubic meters of them if they would:

Make mine in 100% chrome
Upgrade the valving to handle 150 PSI
Guarantee 152DB+ (yeah, like I can actually check this number....)
And ship me a sample now!

The did all three... which is why my horn has black paint on the valve bodies.

I will have just a couple feet from the tank to the horn... and its 3/8 hose. It should hurt pretty good when it goes off. To get some extra slam I might replace the existing solenoid valve with a 1/2" valve I have here...

We'll see...

When I go home today I'll mount it up and see how it all looks...

In short: Horn- Chinese mystery Brand X "Ningbo Special"

Tank - Hoosier Tanks

Pump - "The Monster 150L/min" Southeastern Shanghai Custom Pump Works... some guy named Tony (No joke)

This thing better go boom...

Charles, remember Dan's set up?

The "Inner Tim Allen" in me has surfaced again. This time during an air horn installation.

The roots of this one lay in the end-of-trail event all H2 owners know: The 20-40 minute tire refill.

After blowing about 45 minutes airing up... I began the search for a better way. I found that most 12vDC air pumps only put out around 10L max.

Knowing there had to be a better way, I tapped into my friends in south china an found it. I found a shop in south china that makes a 150L per minute air pump. It runs on 12vDC and draws about 60 amps.

So of course... I ordered one.

Then I thought about it and decided that it would go even faster if I have an air tank.

Having just installed the Gobi rack... I had lots of space up top.

Knowing I was thinking of installing an air horn, I called and asked what size air tank was suggested. The horn vendor sugegsted a .5 gallon tank.

So I bought a 5 gallon tank. I figured a 900% reserve couldn't be a bad thing.

I also bought a Viair 145 psi pressure switch.

And a set of horns....

I spent the better part of tonight fabricating a mount to put the horns in a semi-protected place on the Gobi rack.

The black spray paint is drying on the new mounts right now.

I'm going to run 3/8 hose from the tank to the horn. I hope it can breath through that...



Report on the expected carnage tomorrow after parts are dry and installed....

Cool Charles, what kind of horn did you get?

A bigger tank is the way to go. Mine fills to 150psi and will start refilling at 120psi. A 3 second blast will get the compressor running so it really emptys out the tank fast. Having the tank close to the horn is good too. I think I lose a little flow through the 20' of line I'm using.

One of these days I have to pull the horns and retune them once and for all. They're good but I know they are not up to the 150db.

I'll keep you posted on the pump (You will get one cheap, very cheap...

It cost me about $10,000 for the pump design and first production run. I have a few cubic meters of them coming in about 2 months. First 2 prototype units will be here in 7-10 days.

I'll make sure you get one for "dirt" cheap if you want one. Just remind me once they get here... I'll hook you up. It's a real commercial pump. Wait until you see how I am installing it in my H2... its very, very trick!!
