Air Bag Tank Size ?

[protrash64]

I'm impatient and went with 2 Viair 400's (almost 5cfm IIRC). I originally had a 6gal tank and after filling the compressors would not turn on at all after numerous adjustments. My compressors pull 50amps...so what, you have to wire them anyway..just use some cable...and a big alternator. I used all re7's with 1/2'' line, fyi.

I re-did my set-up with a 5gal tank and 2 re8's at the rear. I used 3/8's line to the back, also, for a little bit more control. After airing up the bags, my compressors now kick on for just a minute to replenish the tank. The re8's really eat more air.
