stevie_b Posted November 18, 2004 Share Posted November 18, 2004 Has anyone fitted air horns to a supra? In particular, what fuse should I use for the power feed to the compressor? I'm presuming I should tap into an existing fuse. Thanks for any help you can give! Quote Link to comment Share on other sites More sharing options...
absz Posted November 18, 2004 Share Posted November 18, 2004 its adviseable to use a seprate feed for the horns through its own relay as the horn pump takes up alot of current. if you use the feed from one of your fuses directly to the horns it will over load the circuit and blow the fuse or melt your wires .

merckx Posted November 18, 2004 Share Posted November 18, 2004 When I fitted an air horn to my van I used the existing wires at the horn to operate the coil circuit on a standard 30 Amp automotive relay. The main power supply was taken directly from the battery and goes to the air horn through the switched part of the relay. It was nice and loud! Not sure if they are a bit extreme for a car though.

I've talked about doing this to the Supra before Will you put up a recording of it when it's done? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted November 19, 2004 Author Share Posted November 19, 2004 Thanks chaps! I'll let you know how I get on. And yes, I think a recording could be arranged. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted November 19, 2004 Share Posted November 19, 2004 Supes horn is a bit Julian Clary isn't it. What we really want is one that lets out a lion or bear growl Quote Link to comment Share on other sites More sharing options...
geoffvalenti Posted November 19, 2004 Share Posted November 19, 2004 I've still got a set of "Dixie" horns lying around somewhere, although I don't think that, even if I was looking for the ultimate in bad taste, that there's enough room to fit them on the Supra Hopefully we're just talking about dual note, rather than musical horns in this thread Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted November 19, 2004 Share Posted November 19, 2004 There is somebody 2 streets over from me that has one of them and as the sound seems to be mobile its almost certainly attached to a vehicle of some sorts. Makes me gigle every time I hear it lol. Quote Link to comment Share on other sites More sharing options...
michael Posted November 19, 2004 Share Posted November 19, 2004 I'm going to be moving my horn to fit an FMIC panel this weekend and was toying with the idea of replacing it at the same time - what are the generic ones from places like Halfords like?

Sharpie Posted November 19, 2004 Share Posted November 19, 2004 Is there not 3 stock horns on the soop in total...? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted November 22, 2004 Author Share Posted November 22, 2004 There certainly are 3 horns! In fact, here they are (see attachment)... I can only find one out of 3, and that one's never worked properly. If I do the airhorn thing, it'll just be a 2-tone, not one that plays a tune!

Paul -C- Posted November 22, 2004 Share Posted November 22, 2004 Why are there 3 horns as standard? Edit: Just noticed it tells ya on the pic: high pitched, low pitched & security. Quote Link to comment Share on other sites More sharing options...

Good question: has anyone picked up a horn (either air or normal piezo) from Halfords? Quote Link to comment Share on other sites More sharing options...
absz Posted November 22, 2004 Share Posted November 22, 2004 just wondering if you if you keeping the original horn and fitting 2-tone on a separate switch ? as it will fail the mot if u have a 2-tone horn go off when the horn is used:conf: Quote Link to comment Share on other sites More sharing options...

The only horn I can find in my engine bay no longer works, so I want to replace it with something beefier. I think (pls correct me if I'm wrong) an airhorn is legal as long as it doesn't play a tune. I would think a 2-tone airhorn is similar (except much louder! ) to the combination of high frequency and low frequency horn fitted to the supe as stock items. Most airhorns I've seen come with at least 2 trumpets, giving 2 notes which sound at the same time. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2004 Share Posted November 22, 2004 I always thought 2 or more tone horns were made illegal ages ago? Quote Link to comment Share on other sites More sharing options...
stevie_b Posted November 22, 2004 Author Share Posted November 22, 2004 Just done a search on the web. Have a look at this: http://www.motester.co.uk/cog.html Under the horns bit, it reckons the horn is legal as long as not a sequential multi-tone, so no dukes of hazard stuff! As long as both notes sound at once. I reckon the stock supe horn should fail on the 3rd point listed anyway... Quote Link to comment Share on other sites More sharing options...
absz Posted November 22, 2004 Share Posted November 22, 2004 just make sure that the note is the same and continiuos i'm sure you can buy air horns with 1 tone with more than one trumpet. Quote Link to comment Share on other sites More sharing options...
toyo rob Posted November 22, 2004 Share Posted November 22, 2004 i bl**dy well hope there legalI got a set on mine. ok they aint the biggest in the world, and they aint the loudest, but they sure get me noticed, have a phobia about being missed so close to the ground, me other cars a Landy and i drive 17 tonne trucks. They do only do a single tone tho and they only really loud when the bonnets open but they sure work and, althoutgh i didnt install them, look to be fairly simple. the little pump type thingy is positioned behind the drivers headlight casing and the horns themselves in the gap next to the expansion tank for the radiator. They are blue, apparently colour makes a difference in the HORN world. Would post a pic but im cheap and dont have a digital camera yet. might try and post a pic tomorrow if i can find one!!

stevie_b Posted December 2, 2004 Author Share Posted December 2, 2004 For those who have fitted air horns already, how do you make use of a spare fuse socket in the fuse box (for the compressor's power feed)? I've had a look at those spare sockets, and I don't think they have any juice going to them at all. Quote Link to comment Share on other sites More sharing options...

JustGav Posted December 2, 2004 Share Posted December 2, 2004 If you get stuck chap, swing round and I'll have a look at it for you... Basically need a good inline fuse and a relay, and about 30 mins worth of time to get it put in properly. Gav Quote Link to comment Share on other sites More sharing options...
stevie_b Posted December 2, 2004 Author Share Posted December 2, 2004 Thanks Gav! Now I know what to get hold of, I'll give it a crack. I'm not used to working on cars though, so I wouldn't be surprised if I'll be making that call soon! BTW are you going to the party on saturday that you mentioned a while ago? Probably won't go myself, money and time are both in short supply Quote Link to comment Share on other sites More sharing options...

I accidentally pretended to sound like I knew what I was saying (my god that's a mouthful). I meant to type "why don't you fit an inline fuse.." or "you could just fit an inline fuse" I was kind of expecting a good reason why not really cheers!
