Ok, I have two viar 450's filling two tanks, one viar to one tank, and all my valves are in my bed (moving them closer to the bags, next week) it takes a while for it to reach 120Psi, then the comps shut off. My questions are, how can i get more "play time"??? where can i mount the comps so they arent so loud???? how can i get the pressure higher???? when the front lays out, it rests on the tranny crossmember, and sits an inch higher then the back, where can i get a new crossmember???? what would it take to have this bitch hop( 1/2" everything ) ?????? sorry its confusing, just have alot of questions???
