Cheap On Board Compressor MOD

So, I was looking for a cheap way to do on board air, but I did not want to pay $300+ for an ARB compressor. I decided against a tank as I will not be powering air tools. I searched around for the best compressor for the price and found the SLIME 2x Heavy Duty Double compressor: 40026 Slime 2X Twin Cylinder Heavy Duty Tire Inflator
I bought it from Wal-Mart online for $65.


Steps:
1. I did not have enough room in the traditional spot for an air compressor because I have an air conditioner, power steering, and cruise control so there is no more space in the spare battery compartment. And as I was probably going to spend $50-$60 towards a fabricated metal holder for the compressor I decided to go a different route. I decided that if I put $25 towards an air filter I could then place the compressor INSIDE the existing air intake box.
2. I used the foam inside the SLIME box to pad the air intake box.
3. I cut a hole in the top of the air intake for the on/off switch.
4. I spliced the wires and cut a hole in the air intake in order to have it permanently connected to the battery.

This is a really quick air compressor. It takes 1.5 minutes to air my 32" tires from 25-35 PSI, and the green hose that comes with the air compressor is also great at letting air out of the tires (Dual purpose).

So there you have it ... better air filter, and on board air compressor for $99.

I can air up bike tires, air beds, and tubes when camping as well as air up my tires after airing them down in order to get through some snow/ice in the mountains. Lemme know what ya'll think.

Very cool, made good use of the air box.

Nice job, I just picked up the cheaper version at wallyworld. Someday I might try to mount it under the hood or somewhere but with quick disconnect so I can remove when not wheeling. Do you think yours will stay cool enough in that location?

Yes, 1 year later and after using it many times I have not had it get too hot. (but it must be said that I am usually using this application in the mountains when the temps are below freezing. ) IF you use this for mud application you might find it does get too hot and you will have to stop.

I will say this though ... This is one of the better electric compressors that I have ever used because of the double pumps it uses it fills my bike tires to 120 psi very quickly, and I have yet to feel like it struggles to refill my tires (This is unlike the other smaller electric compressors I have found).

I've used the pump a few times now and it's a real work horse and very fast. One huge problem though is that when plugged into the cigarette light after the second tie the plug gets extremely hot, I think I actually blew out the lighter socket. I haven't looked yet but it's probably just the fuse. Eventually though I will be mounting under the hood now that I know how well it works.

What size tires are you guys running and how long does it take to fill one? I am looking for a good OBA unit to put where the ABS would normally be on mine unter the master cylinder.

33X12.5, <5 minutes/tire from 15psi to 32psi. Hard to say though because I'd hook it up then shoot the shit about the days ride with the others then realize I was still filing tires LOL. But it's fast.

I was at auto zone last night and found the air filter that you have, did you have to buy any adapters and did you have to cut the stock pipe at all to make it fit? Thanks haha I'm going to copy your setup i really like it.

Looks like a cool idea. Not only for inflating tires, but I have a 12' long inflatable paddleboard. When I bought it I had regular boards but liked the fact that this one would roll up into a backpack. Then I could inflate it onsite. They include a manual pump but I'm far too lazy for that. This 12 volt pump should work great for this too.

And I'm not sure if this is a flaw or what, but I found it listed here at Walmart for $15. The site had a heck of a time processing the order. But it did go thru. So we'll see if it pans out.

Holy crap LOL, I would not have passed that up either, it's even the dual piston model. And it plugs directly to the batt, that would take care of the cig outlet overheating issue. Nice find!!!

Yep, I did have to cut the current intake tubing. Honestly, I was a bit scared of doing this, but looked around and the stock exhaust is cheap if I ever wanna go to a U-Pull-It and get that tubing again.

And you are right $15 is a STEAL~! That pump really is fast. I set low expectations for an electric pump (from previous experience) and was blown away by the double pump x2.

I do like Harber freight, and that $10 air tank is a steal. I am a frequent user of the compressor during the winter so I like the easy access / speed that comes with directly connecting the compressor to the battery. Now if I could only find an excuse to use my winch more ...

would not call that fast... i did the York OBA and i fill a 35X12.5 from 6 to 28 in about 30 seconds... It takes longer for my tire deflators to air down my tires then to inflate them.

Indeed however I did all four of tires and two tires of the guy next to me before he got one done with his little inflator. Yes there are faster inflators but this one does a great job for the price. What did the York run you?

Compressor was 20 bucks.... I bought everything to plumb my jeep and a set of air tools for about 300.

sorry too late to edit. I have always believed you get what you pay for. Just do it right the first time, pay the money to do it right. If you like having a wal-mart compressor that takes longer to fill 1 tire then it takes another setup to air up 4 then by all means go for it. However 5 minutes to air up a 33 is far from "fast".

I did my OBA system before i lifted my rig because i got a deal on the tank and the bracket needed to mount the york on to my engine.
