We will have to get this information on the site. The Vortex port is all about the elimination of port noise. The airflow through a port, particularly near the sidewalls, will create little eddy currents upon exiting the port. These eddy currents become audible puffing noises, which are undesirable. The Vortex port design increases the surface area of the sidewalls of the port and thusly reduces the strength of the eddy currents. This coupled with a curved entrance and exit from the Vortex port eliminates the port created noise.
