i had a 4 pump setup in my first maxima, 48volts. depending on the cca's(cold cranking amps) of your batteries it will be way too fast. i swapped out batteries to lower cca's and it was fine. oviously you can run higher cca batteries and have less batteries or run them at 24 or 36 volts instead.
4 pumps are nice if you have the room, easier to do a 3 wheel and if your batteries are low you can raise the car easier than a 2 pump setup.
witha 2 pump you are using each pump to control one set of wheels (front and rear).
just remember that you should run 2 check valves, or else the fuid will transfer on turns and cause an unsafe truck. kinda like having a dump valve in air systems for a set of wheels. the air or fluid goes through the path of least resistance, so if the weight get transfered to the left on a right turn your left wheel will drop(more) than your right one.
lowrider guys do that sometimes on the back setup to make it easier to 3 wheel. but i doubt you want to do that.
my first setup was a one pump 4 dump setup. definately not worth it. not enough fluid in the tanks for it. the rear used to raise up first(less weight) then the front, and i would dump the back to ride height, it sucked.
good luck, i've had 2 juice setups and wouldnt go any other way
