      oh alright. i didnt know that, i just assumed the higher number, meant that it would be better, even though the 380 is 100% duty cycle, and the 400 is 33% duty cycle. Didnt kiddie rose say it would be better to run two of the 33% rather then one of the 100%??

      Just so everybody is aware here......

      Dual 380's
      Duty cycle: 100% @ 100psi
      Max pressure rating: 200psi
      CFM @ 100psi: 1.77
      CFM @ 150psi: 1.41
      CFM @ 200psi: 1.02


      Dual 400's
      Duty cycle: 33% @ 100psi
      Max pressure rating: 150psi
      CFM @ 100psi: 2.47
      CFM @ 150psi: 1.48
      CFM @ 200psi: NONE


      Dual 444's
      Duty cycle: 100% @ 100psi
      Max pressure rating: 200psi
      CFM @ 100psi: 2.12
      CFM @ 150psi: 1.62
      CFM @ 200psi: 1.13


      Dual 480's
      Duty cycle: 100% @ 100psi
      Max pressure rating: 200psi
      CFM @ 100psi: 2.08
      CFM @ 150psi: 1.55
      CFM @ 200psi: 1.17


      Single Air Zenith OB2
      Duty cycle: 100% @ 200psi
      Max pressure rating: 200psi
      CFM @ 100psi: 2.47
      CFM @ 150psi: 1.83
      CFM @ 200psi: 1.46


      Don't get deceived into thinking that a 444 has a 100% duty cycle at the pressures you will be running, it is only 100% duty cycle UP TO 100psi, after that it starts to drop off. The only compressor that is 100% duty cycle for our pressures that we are running (145, 175 or 200) is the OB2. Plus it only costs $50 more than a dual pack of anything else and is very similar in amperage draw compared to a dual pack and fills quicker and runs cooler. Zero downsides

      I have never even heard of a failure on an ob2, but if it does fail the compressors are fully rebuildable piece by piece for a very reasonable price, compared to just throwing a viair away. Check above for more arguements

      And yes it is your vehicle, your choice completely

      ^ damn this compressor looks amazing !

      I'll prob get that one when my VIAR 444c dies, wonder how much faster it will be, hopefully not louder !

      it defiantly does, ill have to keep that in mind when im ready to get one hopefully next week. And that, the OB2 , id only have to run one of them, correct. rather then two of the 400c's?

      and.... everything ordered, other then the comps. which obviously im still deciding on.



      and, it would be soo cool if it came o tuesday, that being my birthday

      Yup you would only have to run 1 of those OB2's and they outperform ALL of the dual viair compressor packs by far and probably be more reliable also with a 2 year warranty

      I don't understand how 1xOB2 could be faster than 2x444c, the CFM is almost the same

      Dual 444's
      Duty cycle: 100% @ 100psi
      Max pressure rating: 200psi
      CFM @ 100psi: 2.12
      CFM @ 150psi: 1.62
      CFM @ 200psi: 1.13

      Single Air Zenith OB2
      Duty cycle: 100% @ 200psi
      Max pressure rating: 200psi
      CFM @ 100psi: 2.47
      CFM @ 150psi: 1.83
      CFM @ 200psi: 1.46

      I am running dual 400's right now. that was drastically better than the single on. I can't imagine what dual zeniths would be like.
