It equalizes the pressure pulses from exhaust pipe to gas tank , thus it can stabilise / smooth the fuel pressure going into carburator :
(1). Not too lean after acceleration ( off throttle )
(2). Not too rich during acceleration ( full throttle ).
You can stabilse the pressure by using longer pressure line ( people said it's 15cm long ). When using mugen pressure chamber, you can use shorter pressure line and still get the same effect.
Most group A drivers use it.
