On board air

I am in the middle of getting everything ready for a cheap oba set up, plan on installing this weekend, I have the MV 50, But I do have one question, any of you guys have good ideas on were to mount the compressor? I am thinking of an external tank as well.

I will post a complete walk through of my installation after the weekend.

 

I have mine in my tool box. Alot of people mount them under the hood also, I have a 2.5 tank under the bed with the outlet run up the the storge boxs on the side of the bed.

 

nice setup Silver. plan on getting a 450c setup in the near future. i noticed you picked the spot in the back to mount the tank...can it be put up towards the front of the bed? i would rather have it towards the cab, to keep it out of rear wheel spray.

 

Nice setup fellas!

 

I really want to get an onboard air setup except they're damn expensive for a good one. I was looking at getting a Viair 380 compressor and 2.5 gallon tank, or considering a CO2 air system as well. Anyone have any solid reasons to go either way? I like the portability of the CO2 and the constant hi pressure supply(and its a bit cheaper initially) but with the compressor you never have to pay for tank refills. I'm just a bit confused on which one to get.

 

Thanks for the links silverback, looks like building a 10lb setup through those would run about $185 whereas a "source" air tank system through trdparts4u is about $220 and 240 through wheelersoffroad.com and that includes the air hose and a mounting bracket for the tank. The "powertank" brand systems are far more expensive for basically the same thing, so I'd get one of those "source" systems instead. One question on these systems that maybe you could answer- If I added ARB air lockers to my truck, could I just setup the CO2 system to fill a small on board air tank to power the lockers?

 

In what way do you mean a better regulator? More PSI, or flow, or....?

 

Im about to buy an ARB for the rear what do you mean without a gauge you can damage them?

 

O ok, Thanks

 

Ive hurd 100 and now 95 psi, So I dont know guess I find out here soon

 

Are you running an air tank with this compressor or just the compressor?

 

Check your suspension compression /setup etc.

Just throwing this at ya.... I had a similar sized tank (so it appears anyway) mounted above my axle on my jeep. Went to Tellico, broke a shock mount.... and my rear suspension compressed farther than normal and the diff hit the tank and the tank bent the floor upwards pretty good.

Needless to say - I ended up putting a longer & shorter tank in the same location.

 

If I were to do it again, I would skip the whole tank setup and go with just a high-CFM (6 or 7) compressor like an Oasis or an Extreme Air. Regulate it down for lockers and use it full out to fill tires. Don't really need a tank...and it would run air tools.

C02 bottles have a tendancy to run out of C02 at the very worst possible time...like on the trail. A compressor keeps on keeping on and is a one-time investment. It gets hectic enought trying to get ready for a trip out...the last thing I need is something else to worry about being done before I head out...like getting the C02 bottle topped-off.

BTW- it's 80 psi for ARB lockers. 95-100 is a maximum condition. If you shoot 140 psi through your diff, it will blow the seals out, no ifs, ands, buts or maybes about it...it just will.

 

Are you sure about that? You sound kinda iffy on the subject...

 

lol, I have the bad seals to prove it.

I was told you could run 110/120psi w.o a problem...but putting that into practice proved otherwise.

Thanks for the tip

 

here is a link for all kinds of OBA stuff, i know its a lowrider site but who cares...

Am I missing something? Is an OBA setup really this cheap? I was thinking that to do it right was gonna cost somewhere in the neighborhood of $700-$800... Just thought it was more expensive. Compressor, couple hundred. Air tank, less than a hundred...
