Author Topic: OBA setup with superflow comp. (Read 3966 times)

Yota4life · « **on:** Mar 09, 2006, 07:10:10 PM »

Im almost done with the set up. I wanted to have OBA for airing up my 36" iroks after hitting the trail. Also for the occasional use of air tools and soon for activating an ARB locker. I didnt want to spend to much but also have a pretty quick setup.

I found a Superflow MV50 air compressor on ebay for 60$. Heard pepboys used to sell them for around 25$ They put out 2.54 CFM and are the best bang for the buck i could find. Mounted under the hood hardwired to a switch in the cab. Ran a one way check valve to a 1-3 manifold with PSI gauge. Mounted a 2.5 gal. tank from onboardair.com above the rear axle under the bed. Ran one coupler by the front bumper and one out by the back bumper for air hose hook up. I will post pics of the whole set up soon and time how long it takes to air 1 tire up. I still need to buy a pressure switch to splice into the MV50s power. A 85psi on/105psi off should be good.
Heres a couple write-ups on the MV50

Tank 55$
Fittings,man.,gauge 60$
50ft air hose 22$
Couplers 16$
-----------------------
TOTAL $213.00

Ok i got everything finished up. Today i hooked up the pressure switch its a 85psi on/ 115psi off, cost 23$ from central. I ran 2, 3-1 manifolds together so i have one open spot that i put a plug in for now. That will be where i run my arb off of a little later.

I used the set up on saturday to air back up and it took over 20 minutes to air back up from 8-25 PSI. To make the process faster im going to buy a 4air system from 4crawler http://www.4crawler.com/4x4/ForSale/4air.shtml

Heres some pictures

2.5 gal tank from onboardair.com
Used a drain thingy on the bottom to empty any moisture build up or if the pressure switch stops working. Ran one line to the comp. and the other goes to a couple on the rear bumper.

I know i can probley hit this on a rock, im going to move it in a safer place around the bumper but it stays here for now

Another shot, you can see the relay under it. The pressure switch was wired into the relays ground. Theres the in-cab switch wired and ON...

Front coupler. It will also be moved to the top of the bumper where the winch mount is. Once i get the winch mounted i will move the coupler.

If you have any questions about the set up let me know what you think.

Been using a setup like that for the last year. Bought a 7 gallon tank from Walmart for $20. Keeps up with a friends arb compressor. Only thing is, mine doesn't like to start with pressure on the pump. 60+ lbs and it will pop a fuse. I plumbed in a valve to get around this.

I ran a one way check valve also. Ya it does take some time to air up,they are 36" tires though.... but for a 60$ comp its worth it. One day i might go with a faster compressor or get a powertank for airing the tires up. To buy a quickair thats as fast its almost 200$

15 bucks seems a little cheap. you clearly had parts lying around which im sure dont. or your not running an oiling system, theres a cheaper way to set it up. if i were to run a toy compressor i would be sure to carry a spare because if they don't get enough oil there toast. but when working properly they air tires up fawking quick

only thing i had laying around was the tank and the hose and hose clamps ( already had a hose ) my engine came with a ac pump but i burnt it up because i forgot to oil it one night and i aired up 4 trucks worth of tires from 5 psi or less to street pressure.

bought another for 10 bucks and i spent like 5 bucks on a air fitting to run the hose i had off the tank . wire up a switch to hot plumb to the tank and bam done. right now i just put in a teaspoon of oil about every other time i use it or unless im airing up a bunch of people i do it then. dont have my oil seperator yet and im going to find a windshield washer bottle + motor and hook it up to feed oil into my pump easily.

tanks are easy to come by.. hell you could probably make one out of a old propane tank.. seen it done once before i believe.

theres some toy ac pumps that bolt right into smog pump brackets cant remember which one but that makes it so you dont have to build brackets.

Yota4life · « **Reply #15 on:** Mar 16, 2006, 08:17:21 AM »

I would like to go that direction with the ac pump, but i dont have ac in my truck. So i would need a list of parts and a bracket to mount it to. Could you right out a list of needed parts?

derek · « **Reply #16 on:** Mar 16, 2006, 11:27:37 AM »

i have been running the same stock toy compressor for 2 years now. have not burnt it up yet.
i just dump some slick 50 in the intake when i think about it, about every 6 months or so.
airs up tires fast and runs my arb.

Anybody know if Front Range still sells their ac conversion kit? That would have had everything you need but the tank.

I was looking for the webpage as a guide to what you need, but I don't think FROR offers the kit anymore.

HEY MARLIN!

i just went to harbor freight and got all the parts i needed, bought way more stuff than i needed, but live and learn.

I know you need some extra little parts to add to the ac system but im saying what do i need to start with? Do i just need a belt,ac pump bracket, and the ac pump its self and a little wiring and plumbing? I have to start from scratch. Tell me all you know
