Eventuri Gen 2 Audi 8V RS3 and 8S TTRS Stage 3 Carbon Fiber Intake System

With the 8V RS3 Gen 2 and TTRS 8S platforms being widely used for high power builds, Eventuri has developed a groundbreaking intake system to support even those exceeding the 1000whp mark. This intake system has been developed to offer the highest possible flow rate whilst maintaining the lowest intake temperatures possible. Each component has been designed to provide the turbo with a smooth and free flowing path. The intake tube has an internal diameter of 103mm or just over 4″ and has a smooth curvature from the filter housing all the way to the turbo inlet. The filter itself has been specifically designed for this intake and has a huge outer diameter of 210mm or 8.3″ with a filtration surface area of over 130,000mm^2. The patented Venturi housing has been designed to provide the maximum internal volume possible for the RS3 engine bay space available and provides laminar flow to the turbo tube. Finally the duct seals the filter opening to the front slam panel but is not restricted by just the stock entry feed. Eventuri has lifted the front of the duct to now provide an extra opening behind the hood which is equivalent to an extra 7″ diameter hole for the intake to draw from. The resulting system has the capability of flowing 840 CFM at 28″ H2O while keeping intake temperatures at a minimum with the sealed design.

The Eventuri Difference

The 8V RS3/TTRS Eventuri system uses our Patented Carbon fibre Housings which provide an aerodynamically efficient airflow path from the filter to the turbo tubing. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect. You can read more about the housing design and how it works HERE.

Flow Bench Testing

Eventuri conducted flow rate tests using a Superflow SF-1020 to measure the maximum flow rate possible at a pressure drop of 28” H2O. Tests were done on the same day in controlled conditions using the same test jig for each system. They tested their full intake system against the stock airbox system. The results show just how restrictive the stock airbox is, which Eventuri has managed to improve by up to 58% in maximum possible flow rate. Importantly this has been achieved with a sealed intake system so the intake temperatures will also be maintained at a minimum.

Dyno Testing

The Eventuri Stage 3 Intake has been tested by various reputable tuners globally who have been building high powered RS3/TTRS projects for road and track use. The first set of results are from BR Performance Netherlands who tested this system on a TTRS equipped with a TTE700 hybrid turbo. Tests were done on the same day back to back with the hood closed. They tested the stock airbox against the Eventuri stage 3 intake and also with the addition of the Eventuri 4" turbo inlet tube which is an additional product.

Dyno Results Summary:

  • Stock Airbox with Modified Stock Turbo Inlet for TTE700 = 576.5 HP
  • Eventuri Stage 3 Intake with Modified Stock Turbo Inlet for TTE700 = 606.5 HP
  • Eventuri Stage 3 Intake with Eventuri Turbo Inlet for TTE700 = 620.8 HP
