huey45 Posted June 13, 2013 Share Posted June 13, 2013 Hi Guys has anybody fitted two tone air horns to above, if so how did you achieve it if possible I would like to make them switchable from existing factory fits Looking at my centre console there is a spare position for a switch, on righthand side but not fitted, although existing switches in console are oddly shaped ?

cuke Posted June 13, 2013 Share Posted June 13, 2013 Hi, begs the question why on earth, the Focus horns are hardly lacking... Quote Link to comment Share on other sites More sharing options...
FOCA Posted June 13, 2013 Share Posted June 13, 2013 Technically its easy to do, you could just leave the old horn on and just switch the air horns off/ on Quote Link to comment Share on other sites More sharing options...
huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 Hi guys I have had on a couple of times Pratt's pull out in front of me causing me to brake heavily, when questioned, their excuse was I never saw you, or heard me with louder horns if they don't see me will certainly hear me....

huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 I can assure you its not a wind up' I think most cars have feeble wimpy horns, far better be heard than accident Quote Link to comment Share on other sites More sharing options...
cuke Posted June 13, 2013 Share Posted June 13, 2013 Hi, im my opinion loud horns or not they still will not hear or see you, but the focus ones are loud enough. Besides isn't there a maximum decibel of a car horn? Quote Link to comment Share on other sites More sharing options...
huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 Hi I'm not sure of max levels of air horns that can be fitted, I supposed all ones supplied for UK market would be legal, I had on older cars Maserati twins they were never picked up on dreaded M.O.T, but worth checking with your local test centre what db,s your allowed to fit, before becoming illegal My understanding there is no limit to loudness ! They just must not have alternating tones like police, ambulance, fire brigade or any emergency services !!! Quote Link to comment Share on other sites More sharing options...
btmaldon Posted June 13, 2013 Share Posted June 13, 2013 The last time I fitted these was on a Mk3 Cortina. All I did was disconnect the wireing to the original horn and connect it to the air horns. No switches or relays, just a straight swap over. Quote Link to comment Share on other sites More sharing options...

Some may draw a bit more current than the old horn, it may be a good idea to add a relay Quote Link to comment Share on other sites More sharing options...
huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 Hi FOCA thanks for that info, I will bear that in mind possibly needing a relay, now all I have to do is find original Ford horns, as I don't have a workshop manual...

My engine/ car already sounds like a truck, i was already thinking about getting "truck" type air horns (but 12v) - the louder the better! - i think ite a great idea! - i would consider it a safety accident prevention device - the only reason ive not done it is ive been busy with other things and i don't want to add extra weight to the car, but for this - it would be worth it! i wonder if this one is road legal? - http://www.ebay.co.uk/itm/12V-110dB-Antique-Vintage-Car-Air-Horn-Truck-AHH-OOO-GAH-Truck-Van-Boat-Motor-/271163235026#vi-content Quote Link to comment Share on other sites More sharing options...

huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 I'm sure that would be legal as single tone, and 110db, I once found dual air horns rated at 117db, must do another search...lol Quote Link to comment Share on other sites More sharing options...

huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 Hi I'm going round my local MDC's at weekend see what's available, I think no compressor option is best ???... Quote Link to comment Share on other sites More sharing options...
FOCA Posted June 13, 2013 Share Posted June 13, 2013 Hi I'm going round my local MDC's at weekend see what's available, I think no compressor option is best ???... For you - probably, space may be limited and with the air horns you have 3 items - a 200mm/8" horn, a 150mm/6" horn and a 100mm/4" compressor can - its a lot of hardware to find space for, with the twin compressor-fess horns they would probably fit behind the grille How they compare sound-wise - who knows? (the dual horns are not actually air horns, but loud twin "conventional" horns, so may sound different from air horns) You should do a thread on fitting them you could buy/ try both (just kidding/ though they are only about £20 each ) 1 Quote Link to comment Share on other sites More sharing options...
huey45 Posted June 13, 2013 Author Share Posted June 13, 2013 Hi I read your article on your extensively modified Mondeo and being honest I was totally baffled in some items you described you must be very knowledgeable or clever also what you have done must have cost a small fortune I have heard that a free flow air filter will help with a little HP gain and possible water injection into intake manifold downstream of air filter to make incoming air a lot more dense..my focus goes like stink on a very wet day, but I chicken out on lack the of road grip.....LOL Quote Link to comment Share on other sites More sharing options...
ferretfloozy Posted June 14, 2013 Share Posted June 14, 2013 fit a 12v dc 5 pin relay connect the factory fit to the n/c side and the air horns to n/o ..when the relay is energized it will operate the air horns .. use an acc power to energise the relay via an indipendant switch and you can choose which horn to operate ..still using the sterring wheel push button Quote Link to comment Share on other sites More sharing options...
huey45 Posted June 14, 2013 Author Share Posted June 14, 2013 Hi ferretfloozy Thanks for that info, would relay be marked with n/c side and n/o I presume n/c is normally closed and n/o is normally open, I though tags/contacts just had numbers on them from memory ? acc power I presume is accessory power, thats first press of starter button, without depressing the clutch to start engine ? and for switch that's 3 position on/off/on ?

FOCA Posted June 14, 2013 Share Posted June 14, 2013 I was thinking about this, and i thought if you are driving along and you need to use the horn (in an emergency situation) you don't want to be fiddling around with switches etc one answer is to have the air horns normally switched "ready" to sound when the horn switched is pressed, Or a timer circut on the air horn, so by pressing the horn button, first the "regular" horn comes on, then, after a second or so, the air horns come on (just by holding the horn button down) , this way, you could "beep" the (stock) horn "quietly" or use the air horns, all from the regular horn switch, so it would always be ready/ without fiddling with extra switches, and no "non matching" switches in sight (a neater solution - the air horn/s would come on "automatically") I could make up a diagram timer circut - http://cindybob.com/halloween/circuits/timer.html 1 Quote Link to comment Share on other sites More sharing options...
