This impeller is designed to eliminate cavitation, increasing waterpump cooling efficiency and flow rate, and freeing up a little extra HP at higher rpm. Not only is the blade design vastly improved over factory, but impeller to housing tolerances have been reduced to aid with proper waterpump function
