PowerNow slices the single air venturi going into the carburetor into 2 smaller, faster venturis via the PowerNow s “Powerblade . A revolutionary modification to the Powerblade assists the vacuum of the fast moving air by drawing the fastest moving air molecules through a precisely positioned hole in the plate, drastically increasing the speed of the top and bottom venturis entering the cylinder. With this new modified Powerblade, the result is volumetric engine efficiency through uncompromised airflow velocity.
