The unique design of the VForce reed valve system features double the
reed tip surface over a conventional reed valve design. This has two
major benefits: 1) The reed petals only travel half the distance as a
conventional reed valve design to get the same airflow. 2) Because the
reed petals only need to travel half the distance of that on a
conventional reed valve design, there is a greater chance of them being
fully opened as well as a better chance of sealing when they are
"closed". A reed petal never truly "closes" in a classic sense, as it is
always in movement. Consider this, an engine operating at 8,000 RPM
results in a reed petal opening and closing 133 times in one second.
This fact, sheds light on another VForce advantage. Since the petals are
only traveling half the distance, they generally last longer are they
receive less wear than the reed petals on a conventional reed valve
design.
