High-Performance Carbon Fiber Intake System for Audi C8 (RS6 and RS7)

Performance Gains :

• Stock ECU: Increase of 15-25 horsepower and 11-20 ft-lbs of torque.
• Stage 1*: Boost in performance with gains of 45-50 horsepower and 40-45 ft-lbs of torque.
• Stage 1 Acceleration 100-200Km/h: Reduced by 0.6 seconds.
• Stage 2*: Remarkable performance boost of 60-80 horsepower and 60-70 ft-lbs of torque.

Introduction :

The Audi C8 RS6 intake system by Eventuri is the result of meticulous development, extensive testing, and careful prototyping. Our primary goals were to achieve two essential objectives: 1) Improve the flow rate. 2) Ensure smooth airflow. To achieve these objectives, our team of engineers entirely redesigned the airbox, optimizing its volume, increasing flow entry openings, and creating a more favorable filter angle to cater to the turbos. We significantly enlarged the turbo inlets by as much as 85% when measuring the cross-sectional area at the openings. Additionally, our design incorporated an organic-shaped system with a custom rounded panel filter, promoting laminar airflow by eliminating sharp corners. To ensure maximum filtration area while maintaining clean airflow, we collaborated with leading filter manufacturers to develop a bespoke filter element.

Performance Testing :

The Eventuri C8 RS6 intake system underwent independent testing on both the dyno and the road. With higher states of tune demanding more air, the stock airbox became a limiting factor. Respected tuners conducted tests, yielding impressive results.

Stock ECU Testing :

Dyno testing conducted by a respected tuner in the UK on their C8 RS6 equipped with an aftermarket OPF back exhaust showed significant performance gains throughout the RPM range. The stage 1 remap demonstrated even greater improvements, with a highlighted gain of 60 horsepower at the wheels.

Stage 2 Testing :

Dyno testing by a trusted tuner on a stage 2 RS6, equipped with aftermarket downpipes, intercoolers, and their stage 2 remap, displayed a remarkable increase in power. At stage 2 levels, the stock airbox proved to be an even more significant restriction, making the Eventuri intake even more critical. The highlighted point shows the highest gain of 79 horsepower at the wheels.

Drag Strip Testing :

On a local drag strip, a stage 1 RS6 equipped with the Eventuri intake showcased notable improvements in quarter-mile times and 100-200km/h times. The results demonstrated quicker acceleration, with the Eventuri-equipped RS6 outperforming the stock airbox by a considerable margin.

Flow Bench Testing :

Flow rate tests were performed using a Superflow SF-1020 to measure the maximum flow rate at a pressure drop of 28? H2O. The results showcased a 58% increase in flow rate over stock when testing the turbo inlets alone. With the complete Eventuri system, the flow rate surged by 90%, underscoring the restrictive nature of the stock airbox and the remarkable gains achieved with the Eventuri intake.

Product Details : Eventuri Carbon Air Intake RS6 RS7 C8 :

The Eventuri C8 RS6 intake system comprises the following components:

• Carbon Fiber Airbox Base
• Carbon Fiber Airbox Lid
• Bespoke Panel Filter
• Enlarged Turbo Inlets with CNC machined reinforcement
• Custom Silicon Hoses with OEM Specification Clamps
• Custom Made Hardware

Lower Airbox :

The entire airbox system has been redesigned, with increased volume to optimize total flow rate. The redesigned base allows the filter to sit at a more favorable angle to the turbo inlets, resulting in a smoother flow path.

Airbox Lid :

The V2 design, optimized with CFD simulations, provides a smooth flow path from the filter to the inlets. The increased volume and smoother curves ensure improved airflow, in contrast to the stock lid’s cuboid design.

Turbo Inlets :

Enlarged turbo inlets, up to 85% larger than stock inlets, efficiently reduce drag and improve overall performance. CNC machined bushes and rings enhance structural strength, and separate inlets are available for cars with hybrid turbos.

Bespoke Filter :

Collaborating with leading filter manufacturers, Eventuri developed a bespoke 4-layer cotton mesh filter that provides superior filtration with minimal pressure drop.

Conclusion :

The Eventuri C8 RS6 intake system unlocks the full potential of your vehicle, delivering substantial performance gains. Whether on the track or the road, the high-performance intake provides the optimal airflow path, allowing the turbos to operate more efficiently and produce more power throughout the RPM range. Experience improved throttle response and elevated boost pressures with the Eventuri intake system for your Audi C8 (RS6 and RS7). (*Gains measured can vary with different ECU tunes.)
