Quote from: "Niel"Quote from: "muddymesser"in the patrol we use a truck air horn which uses a compresser really loud (can feel the car vibrate when pressed) needs a bit of messing to fit but its great when finishedThats the way I'm going, got a tank, then the right sort of valve to find and it'll be LOUD. Twin truck/boat horn, tried it on 3 bar's of Nitrogen and was pretty loud, 4 bar and even with ear defenders it was too loud to sound for more than a second or two....Normal air horn compressors just won't make enough pressure so I'm looking for a high pressure one, but for the moment CO2 cylinders (out of date extingushers) may have to surfice ;-)in th patrol we have a small gas bottle under the bonnet with about 120 psi in . . . its a suprise it got frew th mot if u look at it a butane bottle next to th exhaust :) 60-70 cm chrome truck horn n a 2 tone train horn under the car 8)
