Features
- VR Velocity Stack is designed to reshape the factory throttle body to boost air flow velocity at each RPM.
- The shape of each VR Velocity Stack is based on intensive airflow research to optimize airflow for each engine’s requirements.
- Creates a balanced airstream between the upper and lower portions of the throttle-body blade, increasing airflow.
- The entrance shape is modified to generate a higher velocity charge at each RPM.
- Allows the intake charge force in the manifold to increase, enhancing throttle response as well as torque and power where it’s usable.
- Streamlines intake air by directing airflow in a controlled manner to reduce turbulence over the air and PCV valve, maximizing efficiency of the factory throttle-body’s diameter.
- Each velocity stack features varied plenum volume in front of the throttle body or in overall length to boost primary and secondary pressure waves during cylinder firing, resulting in a tuned and balanced induction system, improving combustion efficiency, power, and gas mileage.
- Designed to increase power and torque throughout the RPM range, improve throttle response, gas mileage, and acceleration, and installs in minutes.
- Features a patent-pending design.
- Eliminates the need for a ported throttle body by smoothing and reshaping the throttle-body entrance to increase air velocity at each RPM.
- Fits 1998-2002 5.7L Firebird models.
Description
Enhanced Airflow Design. The Velocity Stack improves factory throttle-body airflow by reshaping it to boost air velocity at every RPM, enhancing the intake charge force for improved throttle response, torque, and usable power.
Construction and Appearance. Each stack is engineered based on extensive airflow research to create a balanced airstream within the throttle body and reduce turbulence, maximizing airflow efficiency without requiring porting modifications.
Installation. Installation is straightforward and can be completed in minutes with no drilling required, making it an easy upgrade for performance enthusiasts.
Application. Specifically designed for the 1998-2002 5.7L Firebird to ensure a precise fit and maximize performance benefits for this engine and model.
