For general info: the cite rodgers posted ( Train Horn train horns Loudest Train Horns-Real Train Horns (Powered by CubeCart) ) Sells turn key kits. That means they include everything needed to get you up and running. I will be buying a kit from them that will have a 8gal tank and 2 compressors, and the needed valves, lines, and connectors. I am waiting for Luke to be back so we can set up exactly what I want. And for anyone that wants to know, a 8 gal tank from them measures 29" long and 8 1/2" tall which will fit under the passenger side front door of my 07 F150 screw.
they do the same for inflating tires off road assuming you plan on using co2 not o2 , sporting good stores want like $5 to fill 20oz paintball tanks, assuming you could get a better deal at a gas refill place The Source - The Source High Performance Portable Air System with 10 lb CO2 Tank and Vehicle Mount Bracket #S-KIT10B
Well finally got around to doing a check on my K5s. The earth f/n shakes when all 5 horns get to talking! The compressor was sitting at about 160psi but without a proper seal( a rag) it wasn't getting the full160 psi. ENJOY! Sent from my iPhone4 using Tapatalk.
