This is the valve used to release the air from behind a diaphram or piston valve, causing it to open. It can vary in flow from a schraeder_valve to a 2" ball valve and above, but there are some problems that indicate the need for a higher flow valve:
- "honking" of the valve. This loud noise indicates that your valve is ocilating open and closed.
- A 'dull' sounding launch. (note that this does not apply in the case of a chamber to barrel ratio near optimum, because there isn't much energy left over to make a loud "crack".)
- The GGDT indicates that your prefomance would be improved if you got a larger one.
