VForce VFORCE4RI Reed Valve System

The VForce4Ri utilizes a winged air guide that increases air velocity for a dramatic gain in throttle response. Paired with the new winged air guide is a custom intake manifold boot that offers a straighter shot to the intake that greatly enhances both airflow and performance. The VForce4Ri also incorporates carbon fiber reed petals designed to ensure superior reliability and maximum performance.

All “R” models include a rubber overmolded pad on the reed tip area of the reed cage to significantly improve reed petal life.

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design.

Features

• All-new reed petal resin system, carbon fiber and lay-up
• Pre-curved reed petal ensures better seal at tip
• Wider reed cage for maximum airflow
• Combined reed tip area increased by 10.5% resulting in increased total air flow
• Airfoil shape added to cage tip to increase air velocity from outer ports
• Long reed stops added to progressively slow petal tip velocity, for increased petal durability
• Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape
