how much pressure can one bag take

i know we've all seen trucks that hit the switch and the truck comes off the ground about 6-8 inches which granted isn't that much compared to some of the shit i've seen in videos but how much pressure will it take to hop?i know it all depends on what your running and nitrogen and on and on but is there a simpler way.

valves close to the bag and good switch control, lots of psi and good flow.

yeah theres a noticable difference with the valves on the bags.... mine are mounted directly on them. it helps it dump a hell of a lot faster which aids in hoppin

It also empties your tank a lot slower to have the valves on the bags. Think about it - Would you rather fill and dump ... an airbag 5 times, or fill and dump a bag and 20 feet of line 3 times?
