Another newbie question, is there a way to use the a/c compressor as a general air compressor? I don't like a/c, and if I can't use it for OBA then I'm gonna pull the compressor out and scrap it. I wouldn't need it for anything more than airing up the tires. Any suggestions?
Absolutely. Look up york on board air. These are oil bath compressors if you have the box style. Cut the hoses put on a filter and an output. Oh technically you should have a shop recycle the freon. For the environment.

They make great OBA pumps. There are a few more components you will want for example you need something to filter out the oil and a pressure shutoff switch. Like Jonnyworld said do a search on the internet. It's a pretty popular conversion. I think there is even a company that provides a 'kit' with all the parts you need.
I have york OBA on the honcho. It's even wired into the TBI so that it increases the engine idle speed when I turn it on.
I have twin Viair electric compressors on my LX450 and like them WAY WAY better. No need to have the engine running which is a big plus for me. I hate having to listen to the loud engine while filling up the tires. I dunno what model I have, but it's the one rated for 40" tires.
The point is that you may consider electric air compressors as they aren't that much more $$$ and can work just as good, if not better.

Sounds like he already has the compressor on his vehicle. So the electric would cost a lot more than the few components to convert the york. And the volume of air from a york can power air tools if you attach an air tank.

The round gm style will work. But it has to have an oiler in the line. Because they are designed to have oil in the freon. The york is an oil bath design. So it only needs a air filter on input.

Hop on YouTube. Search for Sanderson OBA conversions. Both it and the york will function as air and since you have a working one, your money way ahead.
https://ck5.com/forums/search/16976890/ ... le_only]=1 . This is from another site I belong to. IIRC it helps if you can throttle up the engine when using compressor. The majority of the parts can be gotten cheap,under $20. If you have a metal recycle nearby. Every week when I go there there is a new used unit being recycled. Once the motor or pump goes south they get rid of them. Buy a complete unit as you can find. You will wind up with a tank, pressure gauge,pressure switch.and maybe air connector. Good luck. Opps, almost forgot, the york does still need an oiling system as the oil does enter the piston and eventually require a refill. Best to put a oil/water filter on your output for air.

I pitty the foo' without AC where you live!
Why not both? Leave the factory york or Sanderson as AC and build a bracket to hold a second one for OBA? Not like there isn't plenty of room in a fsj engine bay.
I see most of the electric options as a light weight version which won't last very long. Unless you spend the crazy money on a dual cylinder ARB which may have a similar ability as a york but still requires electric power to run. Run it long enough and you'll still have to start the motor to recharge the battery. The York 210 has a pretty good output.

I went with the twin ARB and compared to the jkowner test it was a bit slower than the mv90. I don't know what rim size the jkowner was running and, of course, accuracy in our measurements is going to create some variability. That MV-90 is BIG.
37" tire: I went from 11 to 22 in the first 60 seconds. In two minutes I was at 30 and at two and a half at 35. Obviously it takes longer for each PSI the higher the PSI of the tire. (Two tires from 11 to 35 took about 5 minutes 30 seconds including moving from one tire to the other). If I get a chance I will try a specific 12 to 28 psi test for a 'more accurate' comparison.
I also tried this using my shop compressor with a tank. Eleven gallon tank, 3.5HP and max pressure of 125. I let the tank fill before I started. Again 37" tires starting at 11psi. One tire filled to 30psi in about 78 seconds. The compressor kicked on at 90psi after about 20 seconds.
If you go with an electric compressor my suggestion is you 'hard mount it'. I had a pair of mv-50's in the bags and by the time I got the first one hooked up to my battery and on the first tire my buddy was already on his second tire. Then when you are all done you have to pack it all up and secure it, I would wait a minute or two for them to cool down. So a lot of the time was spent packing/unpacking.
Great test data, will e. For the record, you are right. That MV90 is a hoss. It's big and fairly heavy. Also, I would bet that your twin ARB will last a fair bit longer than the Superflow. But, it's cheap and it really does work pretty quick. I bought it because I air up to 45psi on the waggy tires. It keeps the psi climbing all the way versus my old MV50 which got slow after 27psi or so.

I run both OBA with a York and AC (FS10). I have maybe $70 in my OBA system. Works just fine. Got my intake filter and housing from McMaster for I think six dollars. Beats the hell out of what Kilby sells. 50 feet of air hose for $30, homemade junction block. Rest of the money in brass fittings. No electric system can offer the same bang for the buck.
