Wifey Air System Build

Check out the Jacos too if you haven't already. They're really good. Better yet, buy my Haltecs!

 

haha I got plenty of them already. ill have to take a look.

 

Looks like you just drilled through some sheet metal to mount these in the wheel wells? How did you do the rear? Currently building out my own version of the kit and considering either copying the Rago mounts with some scrap metal or just drilling through the body. I'd prefer to keep things frame-mounted.

 

There are two open holes on either side that I used for the rear with my setup. Just sandwiched the frame with the air fittings by using some fender washers.

 

I drilled through the frame for the rears

I know this is an old post now, but thanks for posting all the info. I've been wanting to DIY my own "wifey" system for a while now, and this is all helpful stuff.
I DIY'd my own morrflate hose a couple years ago and it's served me well... it's just a pain in the ass to take out and put away every damn time! Just that part alone, takes more damn time than actually airing-up, and my buddies still finish in the same amount of time, doing each tire individually. lmao

I can vouch for the Haltecs though, they kick ass in my opinion. super solid. (If you still have yours and wanna get rid of em, I might consider your offer, haha)

The only things I wanna change from the original design is to use larger diameter hose and to do away with all those damn push-to-connect fittings... they just don't make sense in this application. Not gonna be taking it apart any time soon after installing, so no idea why the guy who designed it picked those, aside from quick and simple installation. They limit use to those skinny plastic airlines which would restrict the hell out of your airflow, and that's only gonna make your compressor work harder than it needs to, ad take longer to air up (imagine trying to breathe through a straw, lol). Plus I imagine that normal hose barbs and clamps are slightly cheaper.

Anyways, where might I find those schrader valves that can mount through holes like that? and what sorta fitting is on the other side?

 

OH!!!!

 

I used the chucks from MORRflate and they are great. I completed an install based on the wifey system because my Maxi Trac compressor puts out too much air to fill one tire at a time without burning out the motor. I took a lot of steps to maximize airflow by removing bottlenecks. I still used the plastic 3/8 line for a few reasons, but the main one is that the Schrader valve core on your tires is an unavoidable bottleneck. Even if you were to add a second set of valves to your wheels without the cores (which I've seen) the Shrader valves on the frame would still be the bottleneck, so then you'd have to look at a different type of quick connection for that part. With my setup, I can fill all 4 285/75r16 tires from ~16 to ~32 in less than 4 minutes. I think I'd have diminishing returns on the amount of effort to remove more bottlenecks.

The second reason to stick with the quick connects is because of how many specialty fittings there are for them. Here are the Shrader valve bulkhead adapters I used for the frame fittings on my setup: https://switchsuspension.com/viair-3-8-ptc-schrader-valve-nickle-plated/

My compressor is still external since it's huge and not weatherproof, but here's my setup until I can mount it behind the rear seats (I've also got the rears connected here, just not shown): https://youtube.com/shorts/KSZm5s3vXwg?feature=share

 

Thank you for the input. Looking at that website with the PTC fittings, I didn't realize the make so many different sizes available... It seems a little more tantalizing now I know that I'm not really that restricted in size... These fittings are kinda expensive, but idk, I guess it may be worth it, simply for ease and speed of installation.
Just wondering, do you know if that 3/8 is ID or OD?

Also, which maxi trac compressor do you have? the 180 lpm or the 300 lpm? That 300 lpm is crazy, I didn't even know that existed haha. That's over 10 cfm!
I have a smittybilt compressor, i think it's like 5.6 cfm or something.

 

also I just want to put it out there, that regardless of any bottlenecks, it's still beneficial to have larger airline versus smaller, as it would decrease overall resistance to flow. The longer the flow path, the greater the resistance, so you can reduce that resistance by increasing the diameter. Even though the schrader valve has a very small diameter compared to the airline, that reduced diameter is only over a very short distance, therefore it doesn't add as significant an amount of resistance to flow, as one might expect. I mean, it's still a bottleneck, but my point is that the overall flow rate would still be increased by having larger diameter airline. I checked the maths, found here: https://physics.stackexchange.com/q...-constant-diameter-hose-vs-flow-rate-and-pres
