"Large blower" performance in a smaller package that fits most existing Vortech bracketry. The V-7 Series combines the advanced technology and race-proven performance and fits most of our existing mounting bracketry. The V-7 is designed for vehicles with highly modified engines and extreme CFM/boost demands. All units feature our exclusive D-port volute for improved efficiency and require the use of a Vortech Racing Bypass Valve or larger to meet discharge flow demands. The heavy duty (H/D) configuration includes high speed, ceramic hybrid ball bearings, ideal for race applications, and is compatible with cog pulley/Gilmer style drive setups.
