The York compressor's the best way to go for sure as far as high volume air. Can easily run impact guns off it. Gotta make sure ya keep oil in it though or they'll burn up after a while. And make damned sure ya get the belt routed correctly. Previous owner of the Turd had a bullshit kit from Nemesis to mount one on the hemi. Totally fucked up design.
So we then went with the twin ARB instead. Which is a suitable replacement in my opinion but definitely ain't got the balls of a York. Had it under the passenger seat for awhile but got tired of listenin' to it and it wouldn't fit no more anyhow once we lowered the seats for more headroom. So put the stereo amp under there instead and moved the ARB compressor under the hood. I like that better. It's also hooked to one of them deals Alasha's talkin' 'bout where you pipe the air down the frame rails and then hook all 4 tires into the system at once. It's a pretty damned convenient to let the system do all the work of airin' up or down while ya stand there and drink Coors.
