I have been looking at this type aircompressor.
http://www.onboardair.com/web-instructions/oba_manual.pdf
The stock compressor supplies enough to work the stock system, IF you
are not in a hurry. But not enough to run three train horns.<G> Or
help out someone else. Or air up the tires on my dune buggy. I can
come up with a dozen reasons to have a engine powered compressor that
can be engaged/disengaged with a switch on the dash and an electric
clutch. I have seen this style at the local Jeep run and it works
great. My thought is to leave the stock compressor in place (back in
the closet) to do normal maintenance of the system and this type for
the big boost.............Terry

oasis makes a 12v compressor that will flow 13-14 CFM! they arent cheap, at around a grand.. though an engine driven compressor is an interesting idea...

Terry,
I already have a 120vac version of that under the couch. I only use
it for leveling once I get there, and for charging the system and
bringing it up to max psi before I leave. Those things are FAST and
move a lot of air in a little time. So much, in fact, that I went
with a smaller drive pulley on the motor because I wasn't sure the
airlines could handle the heat in the air. Once I'm off shore power,
I use the Thomas 317 and it is hurting. Runs forever once you get past
80-90 psi. The Yorks are cheap in men's malls and not to difficult to
find at swap meets. I lugged around about 10 of them for a couple of
years to sell at GMC flea markets for $15 each. I ended up giving
away the last two (have you used it yet Gary?). They require almost
no mods to pump air vice refridgerant, Just a fitting and a K&N
breather type filter. IMHO, the ones they sell for the Jeep crowd are
waaaay overpriced.
I'm still looking hard at Zenithaire.

Matt is correct, you usually run a colesing(?) filter after the pump to pull the oil out. There is also a mod you can do the the pump so less oil comes flying out.
I have 3 of these pumps, well 1 is already in use on my streetrod, I'd like to put one on the GMC, but am working on how to do it.
Engine driven would be great as it would be cheaper since there is no expensive electric motor. But you need a pulley and bracketry to mount the thing. Also then you'd have to start the engine to pump up the system... The bracketry I can handle, the pulley I'm still looking for, unless you use the AC pulley, but it's already pretty dang long!
Electric would be nice as you wouldn't have to figure out how to mount it to the engine, but then you have to buy a motor and they are $$$

Yes, we should be home and you're more than welcome to use the spot,
tools or anything else you need. The little apartment alongside the
house is now used as a guest shower, restroom etc. I'll see if I have
anything heavy that needs lifting while you're visiting:>)

Bad, bad bug. I ended up with permanent damage to my vocal box.
That'll teach me to ignore a sore throat. If it hadn't been for Larry
Weidner, I'dve never made it through my presentation at Pueblo. I
went out and bought 5 lbs of cough drops after that. That infection
lasted 6 weeks! Good to know that it was non-contagious though.
As Dan would say, "Git a goin" on that '23!
