Anybody any advice on air horns?

Hello all,

I require some advice on air horns.

We are doing a banger rally in the summer and I need to source some loud air horns. Does anybody have any experience of the ebay specials such as the one in the link?

For some reason I have doubts about how loud they claim to be.

Any other recommendations based on experience will help also.

Thanks

The last banger rally I went on everyone hated the one guy with air horns. Please don't use them non stop!

Thats a good point. It was only going to be used at certain points but I take on board what you've said and wont over use.

If that's truly 150 db that will be insanely loud. I used to have a Stebel Magnum on my old bike, which was supposed to be 139 db and was louder than most truck horns. Every 3db is a doubling of the pressure, so pretty much double the volume. 150 db should be enough to rupture someone eardrum if you point it at them

Depending on how and where you're fitting it you might want a relay as they can take a lot of power, and a lot of cars are designed to have pretty weedy horns so don't have the wiring for it.

I fitted this to my B5.5 Passat to wake up the MLMs when commuting on the M4 last year.

Horn runs at 120dB, and the compressor and tank required is 2.5l. Apart from the parts below, I also needed a couple of relays, a 12v solenoid to control the air flow to the horn and some hose and fittings. It probably ended up costing me about £250 and a weekend fitting in the end.
