Where is a good location to mount a Vair air compressor under the hood?

Where is a good location to mount a Vair air compressor under the hood? I had it mounted on a tray under the master brake cylinder on my TJ but there is no tray there on the JK. Not sure if I like where the ARB air compressor bracket puts it and how a Vair air compressor would mount to the ARB bracket.

After looking at the Jeep Swag install I don't mind the location. Just have to figure out if I want to make a bracket or just buy one (easier).

Just buy the bracket. It's not expensive and it makes mounting the compressor easy peasy.

I like making things for my Jeeps but it is just a few mouse clicks and a little typing to order it.

It's very well designed and sits the compressor in a high, well ventilated spot and also allows the sPOD "source" placement !!

I'm running the WOODS VIAIR kit with the 2 gallon tank and it works great.

I'm looking at that kit. What size tires do you run and when you air down what PSI do you start at and go to and how long does it take to fill em up?

I got the Viair 20001 200 psi kit from Woods.
I thought about using his under hood kit but the 2 gal tank won't fit behind the radiator because the overflow jug is in the way.
My plan now is to relocate the muffler and enlarge the the rear storage thing to house the whole system.
This will probably happen in a few weeks. I'll post when it's done

I'm running 35s on 17s. Was at Rausch Creek last weekend, aired down to 15 psi from 28 psi, air up took approx 15 minutes.

Here is the link to Wood's "Viair 400H ( 400C) torture test - Small compressor > Big results".

Viair 400H ( 400C) torture test - Small compressor > Big results - JkOwners.com - The Community for Jeep JK 4x4 Owners

On the tire fill testing the compressor filled four 37" tires from 9 PSI to 27 PSI in 16 minutes.

What have we learned from all this? First of all, we know that this is only a 33% duty cycle compressor. But two and a half hours at 30 PSI, that's friggin great. For filling tires, the 400C and 400H represent what I believe is by far the best value for compressor based onboard air systems.

Has anyone mounted an air compressor under the battery tray? Can the vair compressors be mounted on their side or unside down?

So do I, but some things are just to big a pain in the butt when you can buy them cheaply.

Tested fitted my Vair 400H and it seems to be a tight fit so buying the bracket is much easier than having to make it. Was going to get the tank brackets but the Vair 2.5 gallon air tank will not fit from what I have found out.

I have the bracket now but was thinking on how strong is the brake booster with the added weight of the compressor? Does anyone know if this could be a issue over time?
