Sanden compressor required 7.5v to clamp the clutch, which you could turn up your voltage regulator to get i would think, or the 8 volt battery route, and 6 might just work.

Also, you could just run it clutchless and compressor on all the time, but you'd need to set it up like an old ac system that did that, and use a hot gas bypass like the 6v caddies of that era or something else to relieve the excessive pressure.

We researched the crap out of this topic and the best advice is this:

Get a cheap sanden, mount it and wire it up with a toggle switch, fire the car up and flip the switch, and see if it closes.

If not, wire it up and convert the car to 12v and be done. There's rigging you can do with voltage up-converters and what not, but testing and if it doesn't work, then converting, is the most sensible way.
