Using its in-house Superflow SF-1020 Flow Bench, Unitronic Engineers 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.
Airflow Simulations

With a product like this 4” Turbo Inlet, it was important for aspects such as positive crankcase ventilation (PCV) to be analyzed to ensure that the PCV system will continue to function as originally intended by Audi's Engineers. In keeping consistent with the factory emissions and PCV systems, Unitronic’s fully integrated PCV routing allows for proper ventilation. A pressure plot of the PCV exit shows that it has been positioned for optimized function, aligned with the factory’s intent.
