Using its in-house Superflow SF-1020 Flow Bench, Unitronic Engineers further validated designs to ensure that the Unitronic 4” Turbo Inlet effectively optimizes airflow in a variety of conditions. The OEM inlet yielded a peak flow rate of 581 CFM at 28” of H2O (Aq), while the Unitronic 4” Turbo Inlet Elbow achieved 744 CFM, for a gain of 28% over the OEM inlet.
