Well, I'm need 2 new compressors since mine are dead, whats the difference between the Viair 380 and the Viair 400?? Is it just the PSI? I'll probably buy them in the next couple of weeks... and also do you think an 8 gallon tank w/ 8 port is enough?? thanks

what psi do you plan on running your truck? 145 or 200?

the 380 is 100% cycle as where the 400 is 33%



i have 2 of the 400's, and i want to upgrade to the new oasis.... :)

380 is 50% duty cycle at 100psi and yeah, Doug, I noticed my 380 didn't have the 1/2" fitting you called for on that chart and meant to call you on it. I had the bushings already to make it work so it slipped my mind since it wasn't a problem for me.

If you're only gonna run 150, I would rather go with two 400's over the 380's. It will fill faster, by at least 45 seconds, on 110-145. Unless you plan on playing ALOT with the air system, I'd go with the 400's.

Tim, btw, the 380 is 100% at 100psi, and 55% at 200psi, based on Viair's website.
