The resulting S34 SuperDuper Insuction Bundle offers discerning enthusiasts, unlocking flow for power increases on Dynamic+ Tuning over the factory intake system, sporty induction and turbocharger sounds, and a beautiful carbon fiber shroud—all while utilizing the highest-flowing turbo inlet on the market.
Why are the Factory Intake & Turbo Inlet Insufficient:
An upgraded intake system is critical when looking to optimize the performance of your twin-turbocharged Audi B9/B9.5 RS4 or RS5. The factory intake system consists of a restrictive paper filter housed in a small, enclosed airbox that requires frequent replacement. This airbox is then connected with a corrugated plastic hose to the insufficiently sized turbo inlet, causing turbulence and further restriction as air travels through the factory intake system. While some opt to upgrade the factory airbox alone, this removes some but not all restrictions and shortcomings within the intake system.
The factory turbo inlet has a peak internal diameter of 66mm at the opening, which is quickly split in half and divided between the two turbochargers evenly. Because of this design, the cross-sectional area for airflow through the factory turbo inlet is reduced, resulting in inadequate airflow and lower velocity as air enters the turbochargers. This design was likely engineered this way for cost-savings to keep manufacturing costs lower.
What Does All This Restriction Mean for Performance?
When your turbochargers generate boost under acceleration, they need ample airflow to meet the target boost level commanded by the ECU—regardless of the intake or turbochargers installed. If a restrictive intake, such as the factory system, is installed, it can cause airflow deficiencies that force the ECU must compensate to maintain the target turbocharger boost levels. This is typically achieved by increasing the Wastegate Duty Cycle (WGDC), which puts additional demand on the turbochargers to reach those target boost levels. Much like sucking air in through a straw, you will find it easier to suck in more air through a larger straw as opposed to a smaller, more restrictive straw. Similarly, the turbochargers must work extra hard to make up for this lack of airflow.
As the turbochargers work harder, they generate higher compressor and exhaust turbine temperatures, resulting in hotter turbochargers and intake temperatures.
These inefficiencies and restrictions that the turbochargers must overcome and compensate for due to an insufficient intake system can reduce your engine's power output and generate increased heat, whether your RS4 or RS5 is stock, tuned, or utilizes upgraded hybrid turbochargers.
