On-board air vs. portable air compressor

[GSequoia]

I have CO2 and enjoy it.

That said I've got ARBs and an associated compressor and will be plumbing it for additional air one day. CO2 does run out if you don't plan well (or, say, have a leaky valve).

I have C02 and use it for ARBs and tires. Pros: Quiet, simple, high volume and pressure. Cons: Limited supply, expensive to fill - all the shops around here started doing cylinder exchange only, so 10lb tank is about $30.

I'm going to keep the tank for lockers only and mount a Viair for tires.

Highly recommend the 450C. My only complaint is more storage capacity, as I only run a 2 gal tank. I've love to have an aluminum tank built to the dimensions of the storage space under my driver's side rear seat.

I'm a big fan of CO2. You don't have to spend the big money on the Powertank kits and whatnot either.

Just a plain ol' 20 lb CO2 tank and a oxy regulator off of Ebay. Less than 150 bucks usually to get the setup. Just make sure it doesn't have a siphon tube in it. You want one without a Siphon tube. It takes a long time to run a 20 lb unit down unless you are airing up a lot of big tires.

I use a Viar Portable compressor fast on air ups on 33x12:50's from 17 to 32 psi continuous duty and @170 psi. Really nice kit everything included that you will need.
