Considering the wait time I had when I was running the twin 480's and the fact that my dual batteries were still going dead all the time, I'd say yes. The amperage draw from the electric compressors is enormous; so much that the valves didn't want to open when they were running unless I had the truck running and throttle pinned.

I spoke with the guy that builds/rebuilds these yorks today at length. He's a mobile mechanic and has been running one since 1999 for at least 5hrs daily for his air tools. He said that they're made to pump up to 2500psi and the external lines are the weak point (meaning everything that we would attach to it). It can be made to pump way faster with some creative pulley setup. I know 75dually changed his around somehow with a different pulley from Kilbys. Mine being a brand new rebuild, the rings still need to seat I guess so the "blow by" or oil in the lines should lessen over time with use. 75dually went through his himself, so he can probably answer specific questions better than I can. For your build, I expect that you won't wait long before moving over to one of these too. This company is out of San Jose, so you could get it quickly.
