Nothing too fancy, just a shelf bracket to drop a second Sanden compressor on the driver-side for OBA:






Belt alignment looks off in that picture, not sure why? Cell phone camera... Regardless, now I just need to get my air fittings and I'll be good to go!

From a structural stand point I would recommend running a brace back (toward the rear of the vehicle) somewhere on the block so that you have a more solid mount. Right now you have two pointing points that are more or less vertical (I know the lower is slightly farther back) and don't offer much support for/aft. The best mounting will have a triangulated attachment. Looks good other than that, I like the idea. I would like to do something similar with a York compressor I have in the garage but have to figure out what to do with the air filter.

Although I can understand exactly what you're saying, anything more than what's there would be pure overkill in this installation... Right now there is roughly 6" of horizontal (for/aft) seperation between the mounting centerlines, and other than inertia from the mass of the compressor itself, there is no significant force acting for/aft. The belt tension created moment is easily controlled with the 6" seperation.
I've seen people run their intakes through the cowl, but I personally think that's a terrible idea; easier ingress of water and the intake becomes blocked when there's snow on the vehicle.

That is probably a great point for your neck of the woods... Not such an issue over here in the PNW, especially since mine lives in the shop unless it's on the trail, so excessive snow buildup on the cowl isn't a problem.
