"Large blower" performance in a smaller package. The NOVI 2200R combines the advanced technology and race-proven performance and fits most existing Paxton and Vortech mounting bracketry. The NOVI 2200R 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 requires 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.
