OBA -> On Board Air Mega Thread & BS

Thanks for the info, I just figured it wouldn’t be an issue because they put the plug in the bed.

 

I'm considering this kit:

VIAIR 200 PSI Ultra Duty Onboard Air System

$545 Viair 20001 PSI Ultra Duty Onboard Air System

Does anyone here have any experience with it?

I apologize if there is information here already. I looked at the links in the beginning of this thread, and the last few pages.

This is not the same kit linked on the previous page.

 

So, got my compressor mounted in the bedside cubby.

anyone see an issue with this line routing? Too close to the power conduit?

 

Could be OCD on my part but I’d like to see that coupling area strapped to something solid that still allows the hoses to flex and then zip tie the split loom to the rubber hose since the braided hose is the one that gets hotter. The split loom will take the wear as it is but just on principle I’d separate them around those nutserts and the hose clamp.

 

Would like to do something like that but the way everything’s positioned is kinda difficult. Not a super fan of it, but I’m only running the comp., no tank, at the moment.

The braided hose and the conduit are clamped down to the cubby separately.

Maybe wrap a length of 3/4” conduit about the connectors on the air line?

 

My concern was for the damage that hose clamp could do to the loom with vibration from the compressor. The coupling area is the only section of the airline where it’s rigid and where a clamp could stifle the vibration. If it’s already clamped there then no need for another. If not, a vynil coated conduit clamp might do the trick. Or maybe just loosen and rotate the hose clamp so the corner of the screw isn’t angled into the loom above it. Hard to tell if it’s even an issue since there maybe some space between them but you asked for a criticial eye and that’s all I could come up with after looking at it and thinking “what could go wrong and how could you make that less likely?”. Like I said, could be just OCD on my part.

 

Nope, glad to get a second look. I can stare at stuff for an hour sometimes and not find a solution I like.

The hose clamp I managed to wrap.

Main concern is if the heat from the fittings will be an issue. They’re tho most conductive components in the area of the loom.

 

Sub a dub dub

 

Where’s the most ideal place to mount a water separator. Currently have a 12” SS line coming off compressor into a quick disconnect with DOT lines straight to the chuck located in my bed. Ordered a small water separator for it and was curious of everybody’s opinions on mounting it. Up high close to the connector? Or low in the middle?

 

Right before the chuck at the bed. That way the air has the most time to cool and condense

 

Finally got around to taking photos of my engine bay. The empty side is the passenger side where there seems to be plenty of space to mount a compressor. I've just ordered the ARB single. Is there a bracket that mounts to this side of the engine bay? I've seen the CBI one that goes on the driver side, but I think I will be mounting my SP9100 in this location (using the SDHQ bracket - if anyone can confirm this will fit in my location).
I need some help, please! Thanks

On board air experts, I need your help!

I’m trying to plan out OBA for my front ARB locker and inflating 37’s. I’ve decided to squeeze in a dual ARB compressor, and I know I need the manifold for my locker. I want to run an air coupler to the bumper for inflation. I know I can do that off of the manifold and be done, but I’d kind of like to put a tank in the system as well to help speed up inflation (going to be using a MORRFLATE off the coupler at the bumper).

I think its a simple question, but google hasn’t provided me any answers thus far, so I’m here seeking your help.

The manifold has 2 ports for lockers, and 2 x 1/4 NPT ports, one of those goes to the compressor, which leaves me with 1 x 1/4 port..

Can I run a tank off the remaining port and then run the air coupler hose to the bumper from the tank? Will this mess with the lockers, or are those regulated by the solenoids?

I’m pretty confused, and the more I think about it the more I confuse myself by over thinking it lol.

 

Some will tell you the tank will help when adding a little air or running the locker without needing the compressor to come on but after the initial tank charge is depleted will slow airing up since you have to fill both the tank and the tires. You can connect the manifold to the tank through a shut off valve so you can close the valve and not have to pressurize the tank until after you’ve aired up.

 

Hmmmm, interesting, I hadn’t thought about that. Maybe I’ll just skip the tank for now

 

im confused how a tank would slow down the process. Someone please enlighten me.

Once the tank empties the compressor kicks on (probably before it’s empty) and the now empty air tank acts like an air line. Its nothing more than a tube for the air to pass through. It’s neither being filled nor emptied while air is passing through it...think about it. The same volume of air going into an empty tank is going to be the same volume of air exiting the tank, assuming both the inlet and outlet fittings are the same size.

I think it’s another “hearsay” that tends to spreads around TW.

 

And the plot thickens! I guess my biggest concern is about the locker, would having a tank connected to the manifold mess with the locker at all? Would the tank holding 150 psi be too much, does the solenoid regulate pressure? Or would I have to regulate the line to locker, and where in the system would I do that? I read the 1/8 BSPP fittings for the solenoid are essentially ARB only, so making a regulator at the manifold may be difficult, but I just don’t know.

 

Maybe the tank causes a big drop in pressure and/or cfm, since it’s much larger than the lines going in/out of it? That’s the only reason I could see why a tank would slow things down.

 

supposedly the solenoids are good to 160ish psi. The twin has a pressure switch of 150psi IIRC. So should be fine. Guess we’ll see once my gears are ready.

 

Not hearsay. Think it through.
The tank has a lot more volume than the air lines and the compressor has to bring it all up to the same level that you want each tire to be. Imagine blowing up a ballon then adding a second balloon and trying to blow them both up at the same time. By closing the tank valve you eliminate the extra balloon. After your tires are full you can fill the tank or not but that time isn’t necessarily part of the airing up process.

 

If you want a tank get a tank, the difference is negligible. Is a min or 2 difference if any (who's really tested it) gonna kill you?
