The patented Venturi housing has been designed to provide the maximum internal volume possible for the S3 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. We have 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 can significantly outflow the stock airbox while keeping intake temperatures at a minimum with the sealed design. Our Audi S3 8Y Intake has been independently tested by a reputable tuner in the UK, Regal Autosport.They tested a Audi S3 8Y R in stock form and also with a Tuning Box. Tests were done on the same day back to back with the stock airbox tested first and then the Eventuri fitted. No other changes were made to the car. The first graph shows the results using a stock map.
As can be seen, there is a measurable gain throughout the RPM range of up to 12hp. This gain even on a stock car is noticeable on the road with better throttle response and quicker acceleration.
The second graph shows results when using a tuning box which increases the flow demand from the intake system. The tuning box was used for both the stock airbox and the Eventuri intake without any changes between the tests. With a higher flow demand, the stock airbox presents a higher restriction to the turbo as can be seen by the significant gain achieved with the Eventuri fitted.
We now have higher gains across the RPM range of up to 20hp and 30Nm, which is even more noticeable on the road. We expect gains to be even higher with higher states of tune. The gains are from a combination of reasons: 1 The sealed system keeps IATs low - the S3 engine bay can get heat soaked very quickly so an open cone filter will cause an increase in IAT values resulting in a loss of performance. 2 The Venturi housing provides a smooth transition from the filter to the intake tubes which are both matched to an internal diameter of 94mm.
This helps the turbo to run more efficiently. 3 The entire system is constructed from pure pre-preg carbon fibre which is great at insulating from heat and has smooth internal surfaces as opposed to fibreglass which will have sharp resin lines present. This kit is compatible with the Audi S3 8Y. Audi S3 8Y 20+ TTS 22+. Our Customer Service team will endevour to resolve any issues.
