Eliminates the need for a ported throttle-body by smoothing and reshaping the
throttle-body entrance to increase the incoming air velocity at each given
RPM
The VR velocity stack was designed to reshape the factory throttle-body in
order to boost air flow velocity at each given RPM. The overall shape of each VR
velocity stack has undergone some of the most intensive airflow research that we
have ever done to produce the best overall shape for each engine's airflow
requirements. In order to achieve this we:
Created a balanced airstream between the upper and lower portion of the
throttle-body blade = more airflow.
We then changed the shape of the entrance to build up a higher velocity
charge at each given RPM. This allows the intake charge force in the manifold to
be increased = increased throttle response and added torque and power under the
curve where you can use it.
Streamlining the intake was also achieved by directing the air in a
controlled fashion to reduce any power robbing turbulence over the AIR and PCV
valve to maximize the overall efficiency of the factory throttle-body's overall
diameter.
Each velocity stack features a varied plenum volume whether in front of the
throttle-body or in overall length to help them boost the primary and secondary
pressure waves during the cylinder firing process = a tuned and more balanced
induction system giving you much better overall combustion efficiency = more
power and better gas mileage.
