I finally got around to finishing up my onboard air.
fabbed up a bracket for an old battery tray and rubber mounted it then put the compressor in.
ran 4 gauge to a 300 amp switch and fused it with a 175 amp at the battery.
Ran 300 degree 300 psi 3/8 line for 3 ft with a piece of 2000 degree orange fire shield over the quick connect. No more blisters lol yes I burn the hell out of myself once.
ran that in another quick connect and 25' of 3/8 220 degree 300 psi air line.
From what Ive seen so far, this thing fills a 285 KM2 from 15 to 45 lbs in about 45 seconds.
its rated at 100% duty cycle at 150 psi, but I don't know the cfm. It pulls about 100 amps.
in the couple online tests I found, it was much faster than most anything else including the ARB twin.
its the outback extreme air magnum.
I went with the keyed switch so I can keep the key in the glovebox and not worry about the thing being ran without the hood up.(it gets hot!)
next up is hard line plumbing to a tank in the back but that will have to wait awhile.
