I ran an IR2131 off my York OBA setup on my white 80. I used it to swap tires before and after runs for about 10 years. I had a 2 gallon tank and ran it at 140 psi regulated down to 90. It would run that tool all day long.
It ran out of steam when I was using an air grinder to cut off part of my exhaust that got ripped off years ago. But the tank charged up quickly.
Once you go York, you never go back.
In 2002 I made a spreadsheet comparing all the available products (at that time) when I was looking into adding OBA to my truck. Take a look at the numbers.

Nice comparison. How's the Puma compare?

I agree with the relative cost of the York compared to the others. When building the complete system all the little bits and pieces add up just like the weekly trip to the grocery store. I think with it all said and done I have about $900 in my setup. The compressor was something like $75 and maybe the bracket $200, but all the countless other fittings, filters, connectors, tank, etc just run up the total. I justified the cost by not needing to purchase a separate compressor for my air lockers and the fact that I can air up both my tires and other trail buddies quickly.
 
Joey,

Thanks for putting this robust kit together.

Can I still use my Burrito box with the York installed?

Thanks

:idea: Use the york with a split and t-stat to nuke your burritos in the box with hot air infusion.

Ok, maybe not the best idea.

No idea. It was not available in 2002 when I did the comparisons. I'm sure the numbers are floating around the internets somewhere.

There is no doubt that a York system is more complex and more expensive than any packaged electric unit. I suppose if I was looking for a cheap and easy way to get OBA, I would go with a package unit, however cheap and easy is not my way (left the door open on that one).
I enjoy a well designed and thought out system that will outperform any other product on the market. Exactly why I drive a Land Cruiser.

HERE HERE!! :cheers:

I drive mine for these reasons and the fact that I hate unnecessary money making my wallet fat.
 
I could do a test on my york and puma possibly this week. I have run an 1/2 impact on the york without a tank no problem. What kind of tests would you like to see? It wont exactly be equal because the york doesnt have a tank but i could start by doing some tire fills. A flow gauge would be cool but i dont have one. The york will win anyway.

I have also started on converting my locker to air. My rear motor keeps getting worse. I have rebuilt it twice over the years and its not working again. I havent spent much time on it but would want it triggered through the stock dial and indicator light. I should dig into the schematics so i can buy a solenoid. Ok, mini hijack over.
 
Just for the record, i have the original bracket.... not the new Wits End. The setup i have uses the inner grove, not the outer. The problem i had with the single grove in my case was that the inner grove didnt exist. It was solid with only the outer grove available.

Ive been doing a lot of research on the york OBA systems people are building and have notice a few things.

When using the york for just filling tires it works great but if your using it for an extend period it gets hot and then the compressed air gets really hot! As does the compressor- I didn't ever read about a york overheating though- Read a few threads about filter/water separator melting and 1 even caught fire- So what is the plan for the filter/water separator? Still planning on using a brass filter or have you found a a plastic style that will take high temps? Have you thought about cooling the air before the filter- Semi's gauge how far to place the air dryer down stream by when the air cools down to below 175- They also make sure the water collection point ( They use a air dryer with a desiccant filter that back purges every time the compressor cycles off. the filter also does a decent job collection oil. You probably know this already) is mounted below the compressor- Not hard to do to with where the compressor mounts on the 80-They also have a dedicated wet tank to collect the rest of the moisture. my suggestion is two use two tanks (1 very small and then the main) and install a check valve between the two. The first would be used to cool the air and collect water/oil. Have you thought about those of us who might see freezing temps- I haven't done any reading about what people in freezing climates do to keep water out of the system- I'm probably not the only who would see freezing temps since my 80 is a DD. Just a few rambling thoughts and questions for you to ponder. Also yes, I realize these aren't semi's, I just happen to work on them for a living.

Long time owner of a PUMA and the York is without question a much faster and more powerful set up. That said a PUMA can air up 4 35's from 14 - 36 PSI in less than 10min or less ( at sea level) form the time you stop till you leave. York can do the same job in maybe ~7 min. PUMA with a 3/8" IR gun can remove a properly torqued 80 tire without waiting. I carry an air grinder and you will spend a lot of time waiting with a PUMA compared to a York but if you need it the wait is not a problem.

Bottom line if you want to be king of air supply get a York but to be king you need to pay for it. In the end as king you will either help air up your friends or wait for them to air up themselves.:meh:
 
When it comes to air supply it's always faster the better. If I'm wheeling with friends then I sure don't mind help them air up because they are my friends. If I'm wheeling in a group I still help when I can or if I don't like them then I'll just leave because I gots to go. :hillbilly:

To air up a 35 it take a little over 1 minute for the ARB twin compressor and york can be even faster.
 
i went york as im tired of my 12v compressors..... I've run viair, airbagit, arb, puma and looking forward to real on board air, 37's is hard on the compressors

totally agree! sadly I might do a LS swap or a turbo setup so can't use the onboard air or I'll be first in line to get one.
 
you could easily put a york on an ls setup, the turbo, when i was looking it, I think I could swing it, it would be tough though

I made a simple bracket and mounted a York above the power steering pump on the 5.3 in my 40. The hardest part was getting the right length serpentine belt.
