Who Runs onboard air?

I got a deal on a used york for 46 bucks shipped to me and was wondering who has one how much they spent on it and if it was a good investment... i want it to air up tires air tools and etc let me see some pics also who has a serpantine setup with theirs . i was thinking of removing me ac pump (not functioning, and putting it there my serp setup came off a 4.3l truck
 
the york does not fit in the serp bracket very well ( i have tried), plus the serp pulley costs around $100, your best bet is to mount it on the drives side and run it off the alt, you can get a new pulley for around $40 that allows you to run a v-belt off the alt
 
Try onboardair.com they might have the bracket you need if not you need to make one and that can be a pain!!! But in the end I think its very good investment . But can cost $200-$300 for every thing else
 
I run OBA and there are a couple pics in my gallery the last i looked. I got everything other than the compressor itself from www.Kilbyenterprises.com. Mine is a serp set-up also. I even had to buy the serp clutch/pulley from them and i spent about $500.00 on everything including the bracket kit they sell.
 
Make shore you have a long stroke pump frist . The site will show you how to
 
I've got a medium stroke york and I plan to use it with the kit one of these days. OBA said that it would work fine but it's not totally ideal. Seems to me it was going to cost around 7 bills at the time using my own compressor. Having a bigger tank will help with a medium stroke compressor as well. I've never seen CFM numbers though.
 
Maybe if you use a bigger pulley it might help . Max rpm is 1200-1400rpm . $700 is alittle high I think I'm going to look for a site I saw , to do it for cheap
 
yeh but try finding a place to fill it in middle of the woods!!
 
MY OBA SETUP

I made my own bracket and manifold (which I make and sell BTW :thumb: )

Check out my write-up. I think I spent a total of $75. That was with $25 york, 2 - 5 gallon air tanks and everything else.

Is there a way of telling what stroke it is without having the pulley off?


The three stroke numbers are: 10 = long stroke, 09 = medium stroke, 07 = short stroke.
