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.

Airflow Simulations

Overall product design proceeds through, not only focusing on increasing overall performance of the product, but also the small and often overlooked aspects of the product’s design and function are of utmost importance to Unitronic. With a product like this 4” 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, allowing crankcase pressure to be properly ventilated, as we all know what can happen over the long term, when crankcase pressure is not properly managed. As a result, extra attention was spent to allow for a complete one-piece PCV design. In keeping consistent with the factory emissions and PCV systems, Unitronic’s fully integrated PCV routing functions as it was originally intended. A pressure plot of the PCV exit shows that it has been positioned for optimized function, aligned with the factory’s intent.

Modular Fitment
