How does the DUAL STACK work?
The DUAL STACK funnels are designed to deliver the performance of the short funnel and the long funnel plus α. This means that each funnel does not work only in its own area, but each funnel has a synergistic effect on each other, resulting in increased combustion efficiency and therefore increased performance.
In the case of low throttle opening range
1st funnel
In addition to the rectified air that is inhaled from the 2nd funnel, this funnel assists in the intake of +α negative pressure. This allows more air to be taken in and burned than would normally be the case, leading to an increase in power output at low engine speeds.
2nd funnel
The 2nd funnel acts as the main funnel and draws in rectified air.
In case of full opening range
1st funnel
The 1st funnel acts as the main funnel and quickly draws in the necessary amount of air for combustion.
2nd funnel
The negative pressure caused by the intake of the 1st funnel assists the rectified +α intake air, allowing more air to be taken in and burned than would normally be the case, leading to increased power output at full throttle.
