Rebuilt nathan K3HA. Air system is in the bed of the truck; 5 gallon tank, viair 480c to 200 psi, viair 420c to 175psi, water seperator, lots of fittings, etc. Hose is 3/4" OD 1/2", and valve is a 1/2" ID with 3/4" compression fittings.
I have been doing air horns for a long time and this is by far one of the loudest. I do not normally use this on the street because it is dangerously loud, although, having 30 cars stopped at train tracks from a quarter mile away because they think a train is coming is priceless....albeit, illegal.
need to run it on no more than 150 psi, after 150 it dosent make it louder just makes it sound horrible.
