Got an RS3L on my truck, and adding the RS5T. I use a combination of 10-gallon tanks with 480s at 200 psi, down-regulated to 120 psi, and a line from the truck’s secondary tanks (through a checkvalve) to my horn tanks. Essentially unlimited air !! The RS3L is on the right side of the frame, pointing forward, and the RS5T is going on the left side. Gonna be frickin’ LOUD !!
Holy crap! Sound clip! Sound clip!
Nice! How big is your truck tanks? I know one RS5T is a big time air hog so coupled with a RS3L it’s gonna be definitely hungry for air lol
The truck has eight 5-gallon tanks at 120 psi, plus a monster twin-cylinder compressor powered by the engine. If you blow the horn for more than ten seconds, it starts dipping into the brake supply, but it would take about 30 seconds of continuous blowing to get close to the emergency brake trip-point (50 psi). I’ll have to go to an isolated place soon so I can actually time this.
Oh yeah… that’s alot of air lol That should be more than enough.
I wanna hear toooooo! Awsome. Can’t wait to see some vids.
Forgot to mention: This RS5T is a maximum orifice marine application horn (RS-5T-FX). It’s 3-4 db louder (at 100 ft) and uses 40 cfm more air than the full orifice. Full orifice: 0.125", Variable orifice: 0.80 - 0.125", Maximum(marine): 0.172". It wears the nozzles out 3 times quicker, but I’m not blowing it 300 times a day like I would if it was on a train (or,in this case, on a ship), and I can always send it out to Mike Muha or Ken Kanne for rebuilding. 3-4 db is a big difference; That’s almost 1-1/3 times as loud as the full orifice !
Actually the FX horns weren’t marine use but rather the first RS horns. From what I and other members of another forumm have gathered, the X stands for experimental. They came around when the dome back S series Leslies were still being produced. What throws me off is the fact that they made S-5T-FX’s in the late 60s lol. To be a true as built FX (RS)horn, it should have 5 PAF (Pat Applied For) caps on the power chambers. Pretty rare horn ya got there, and if you ever decide to sell, should bring quite a pretty penny compared to normal RS-5-Ts.
wow. 40 gallons. You’ll be arrested long before you run out of air.
What colors were on S5T when you got it?
Nice rig, two train horns are ganna be awesome on there. Esspecially seeing as youll never run out of air.
I know, Sickening. You’ll be blowing like the trains down here. They blow long after the intersection. lol. They must like train horns too. My friend drives trains and he NEVER heard of a train horn on a car. I was floored with laughter.
just curious, how does your setup affect the brakes?
It’s on an 18wheeler and he’s using the truck’s onboard air supply too. That’s where the truck gets air for its air brakes.
Air brakes on a rig have two functions… 1. Air holds the spring brakes off allowing the wheels to turn. This requires at least 50psi, less pressure in your tanks than that and wheels lock up. 2. When you apply pressure to the brake pedal air is forced through the lines thus applying the brakes on the drums. The less air in your tanks the less you can apply the brakes before your air pressure drops below 50psi and you wheels lock up. On my setup I can blow my P3 for about 30 seconds before pressure drops below 60 psi which is low enough for me to chance locking up my brakes cruising down the road at 60mph. So in short, my setup doesn’t affect my brakes unless I get crazy on the horn.
Video is a MUST! I still want to make a video of my K3LA, but haven’t gotten around to it yet.
I like your sig pic. Did you make that yourself? What are the dimensions?
^ hey thanks! I made it. It is 600x150 pixels.
This thread is useless without video!
