Just like the title says. Has anyone put a trainhorn in their MINI. Would there be any problems as far as space for the pump or the horn itself? Just thought it would be funny for such a small car to be packin such a loud horn...possible consider this for my MINI whenever i get one.

 

How big is the compressor? Is it about the size of a FIAMM airhorn compressor?

If so, you can probably fit it in the crowl space and run the hose into
the radiator area.

 

Lots of people have air horns of some sort... But a locomotive horn, given the size of a single sounding bell on a locomotive, plus the fact that most locomotive horns are actually made of multiple sounding bells, I'm not sure it's something that you could pull off.

If you want a loud air horn, there are lots of other options out there that are better suited for installation in a MINI.

 

There is a lot of space available under the cowl vents. It is exposed to rain, but that shouldn't be a big problem. I installed my road runner horn there, and you can see a big picture here: https://www.northamericanmotoring.co...ad.php?t=20842

I think all those thin metal pipes going into that thing on the left are for the DSC, so if you don't have DSC you might have even more space.
