The bladder pressure is a power booster in hard turns and high G maneuvers. It minimizes speed bleed-off. But it is a pain in the rear to run until your comfortable with it. Bladder tanks and one way check valves in the muffler pressure line are good alternatives for a smaller boost in fuel pressure.
