Hi. If you used 2 x 2.5 gallon tanks that would be enough to run air tools. An on board system will never be as quick to recharge as a proper garage compressor unit, as a garage compressor will run at a minimum of 15cfm (cubic feet per minute). The 12 volt compressors I have go up to about 2.6cfm. But having said that if you have 2 of the 2.5 gal tanks, or a big tank from a lorry, then you could use an air tools for maybe 30 seconds before the compressor kicked in to refill the tanks.
The main use for an on board system is realy to re-inflate tyres, operate air locking diffs, operate air suspension (something I'm looking into) and inflating footballs, boats, air beds, etc.
Going back to the air suspension. I am doing a load of research at the moment regarding air springs. I want to provide a kit that will give better suspension travel and better load carrying. I reckon I could sell a complete kit for about =A31000. This would be 4 x air springs (to replace your coils) 4 x new shocks, on board compressor kit with tank etc, 4 x dash mounted (if you can get your dash apart to fit them!!!) switches and gauges for each spring. As I said, I'm just researching at the moment, and if I do provide a kit it will require a good weekend to fit it and a bit of fabricating, but nothing too tricky. You'd be able to go right down to the bump stops, or right up in the air, maybe giving about 10 inches of travel. And each corner would be independently controlled.
all the best,

Matt,
I was going to take this query off list but perhaps the others would be
interested in the answer as well?
Is the sort of system you're talking about good enough for running
tools? As in grinders, drills, that sort of thing? What's the best size
tank if you want to keep it as small as possible but still be useful?
Jon.
P.S. Yes, I know I've changed the subject on a reply, but it's still in
the context of the original thread!
