I know that lots of companys make them, bd, jacobs, pacbrake. Which one makes the most noise? Do they all come with air tanks that can sufficently power mild... to moderate air horns, and fill up 40" tires?
The Jacobs is vacum operated. The BD is a great brake and really you need to decide how big of a tank you want to run. The PacBrake comes with a 2 (?) gllon tank. I may be wrong on the tank size, but I know it comes with one.
I have a PacBrake PXBR and it has a 1/2 gallon air tank, and a pump with a 20% duty cycle. It would operate air horns, but inflating a 40 inch tire would be asking a lot of it. You could add a larger tank I guess. You don't get a whole lot of noice like 18 wheelers, but you do hear it. I really like the sound of the air release when pulling away from a stop. Several people say they didn't know 2500 dodge's had air brakes.
I would think you would need a pretty big tank to fill up 40" tires as well as a 100% duty compressor.
