AIr Horns

[Peter Jones]

Yep, Arlec brand tank, I got that tank from Kmart for $40. They're setup to fill from a tyre pump but their stock fittings leak like a sieve. They're bigger than you really need but good value for the price. I fill mine from a compressor to about 130PSI.

The horns will sound down to about 40 PSI but if you can get 130 PSI to them they're unbelievable. (150psi is nuts)The manufacturer claims 150dB out of the horns.

I have a smaller 3 litre tank in my other golf which has similar twin horns. It seems ample for a few good sustained blasts. The pop up on ebay every now and then.

The horns are louder than the Connex metro trains, they sound more like the diesel VLINE trains.

My horns came from www.siegeengineering.com

There's more insane setups and videos etc at www.hornblasters.com

What do you use to activate it? Some sort of solenoid valve?

[Peter Jones]

That's right. There's a 12v solenoid right at the base of the horns, you can see it in the first photo. The solenoid just hooks in to the original horn circuit. The black tube coming out of the solenoid is the air line.

does that not cause other people to crash?

[Peter Jones]

Discretion is the key! I'm no road rager so they don't get a lot of use.

Mostly people just look around for the train! No-one usually suspects it's the 30 year old golf that just made that noise.

You are right about people changing direction when they go off. So it's best to use them as horns are supposed to be used, to alert people of a dangerous situation rather than as an expression of anger.

Of course if there's no other traffic about and I happen to be passing through a tunnel or under a bridge I might lapse and have the occasional toot.

Where did you get it?

[Peter Jones]

Mine came with the horns http://www.siegeengineering.com/
They also sell the solenoids on their own.

Kits pop up on e-bay all the time as well.

Like this one in Melbourne. http://cgi.ebay.com.au/BRAND-NEW-100...QQcmdZViewItem

Which is the same as the one on my other golf.

You can also get a manual valve like the truckies use with a chain accross the roof of the cabin. Pirtek or Enzed would probably stock those otherwise a truck wrecker might be worth a visit.
