Topic: What On Board Air To Run ????

[86moneypit]

I have a 04 Dodge CTD 5.9 that I use for my DD and tow rig. 

I want to put an on board air system on it to use for air tools and airing up my rock crawler. Only use air tools to work on the crawler out in woods.

I figured it would be better than putting it on y crawler since there is little room left for this kind of stuff.

Seeing what you guys run or know works well, don’t want to spend a fortune but want a system that will work well.

Thanks Martin

You could prob fit a york in there pretty nicely. Then mount a 10 gallon tank under the truck.
I run a viair 450c and a 2.5 gallon, it can run tools

CO2 tank is so much better than OBA in my opinion.

[junya92toy]

Naw, once its out, its out, air will never run out

[Dr Phat]

Yeah but a 20lb CO2 tank goes a longggg way and its easy enough and cheap enough to fill up at least around my house. I run a 5lb tank in my tow vehicle to fill tires and air tools.

[junya92toy]

Ya but it still can run out, like in the middle of the woods when you need it

CO2 tank is so much better than OBA in my opinion.

Except you know when its cold out / snow wheeling  it will fluctuate with temp and ive eventually had it go to the point where i had no air in my tire. I also had a buddy that would use co2 and it was funny when his bottle would freeze to the ground when he was airing his tires up while snow wheelin

[Dr Phat]

Ah dont have that probelm over here. haha, suits my needs just fine but OBA is nice too.

You know...some heavy duty applications that have air brakes use a compressor that bolts onto the front gear housing and usually will have the power steering pump behind it (in tandem) on the driver's side just below the VP44 injection pump. I don't know for sure if the provisions are there on the Dodge to mount that compressor or not, but if the provision is there and there is room there near the steering shaft, you might be able to get it to work and it will be a direct bolt in deal. All you will need from there is an Air Gov'r from a heavy duty truck and all the plumbing, tank and safety valve to complete the install. Plus, the compressor uses the engine's oil for lube and the engine's coolant to keep it cool. Just a thought.

Thanks for all the info.  I have a co2 tank in my crawler.  Just thinking of something more permeate, I might run air bags and an air horn on the truck soon so i could plumb it for that too.  Think i might go with a standalone unit not something on the motor.  Kind of want something simple maybe a kit or something..

[junya92toy]

Viair 450c kit then

[86moneypit [OP]]

Viair 450c kit then

i like this set up,  what size tank if i want to have little to no lag when running air tools or maybe a die grinder.  I think i have plenty of room under the truck..

[junya92toy]

I have a 2.5 gallon and can use a 1/2 inch impact, prob do  5 or 6 lugnuts before i have to wait, you could go 5 gallon with it

[86moneypit [OP]]

Sounds good to me, i think i will run a 5 gal tank.  How long does it take for you tank to fill?  Do you have to wait at all when airing up?

[junya92toy]

It takes 3 mins 40 secs to fill a 2.5 gallon tank to 150 psi. I charge the tank and can fill a tire, second one takes a little longer, I wait for it to recharge to do the next two, but it is a 100% duty cycle compressor so you could just filling tires, its a small compressor, but works and that is with 35 12.5 15s

[fordh8r]

That doesn't seem very fast when a York compressor will fill an 8 gallon tank in just under a minute with the engine idled up a bit. With the York I'm running, we filled 3 sets of 35's a set of 37's and a set of 33's in just under 30 minutes when we left MCR last year. That time includes moving rigs around to get them close enough to air them up. Just saying.

[junya92toy]

Never said it was fast, just works

[fordh8r]

Nor did I say it didn't work. Since he was asking, I offered my experience with the York so he has some real life data to base his decision on. Nothing more.

[junya92toy]

well  ya, id say york too, but he wanted a bolt in non engine mounted.  Trust me, ive been thinking of how to fit a york on my 3.0 my ac line broke, i might have to pull the compressor and see if i can make it work

[86moneypit [OP]]

I’m not completely stuck on the stand-alone unit yet.  Still doing some research and seeing pros and cons to each set up. 

When you put a York on is it a bolt on and go type of thing or do you need to fab brackets and other stuff.  I can do the fab work just don’t have that much time and wanted something simple that works..   Not trying to spend a crap load of money.  I might be asking for too much.

Thanks for all the info so far..

[junya92toy]

Well yes you will need to make brackets for a york, but you can get a york for around 20 bucks, a setup like mine is like 400

[fordh8r]

The usual "Money VS. Time" scenario.

[junya92toy]

A york is not slow in the CFH department by any means. Some will put out as much air as a 60 gallon shop compressor.

Look at the Puma 12v compressor. 100% duty cycle faster and cheaper than the Viar

[86moneypit [OP]]

Is this Kyle from Fresno, I think we went wheeling at Jose Basin when I first built my runner, i went up with Marco.  I thought I recognized the truck..

Ill check out the Puma 12V.

Do you run this on your truck, what size tank if so?

[88_Pathy]

Yep its me. I have this setup. I think the tank is 1.5 gallons, and it is pretty fast. Not like my CO2 but plenty fast on 37s.

[DrNut]

I know i'm dragging this up from the dead but consider an Oasis Air XD3000 or 4000. Crazy expensive but they kick some serious butt and all your buddies will ask for air.. lol i run one on my tow rig and it has worked great. It even ran my plasma cutter on a job site one day..
