Facts:Performance increase (standard vehicle): 10-13hp, 12-15NmPerformance increase (tuned vehicle): 15-20hp, 25-30NmMaterial: CarbonManufacturer: EventuriExpert opinion: without The S3 8Y intake manifold is a complete redesign of the standard intake manifold right up to the turbo inlet. Taking inspiration from our RS3 intake, we have made the most of the available space to create an intake that is suitable for all power levels, from standard equipment through to high performance systems with hybrid or full frame turbos. This intake system has been developed to provide the highest possible flow rate while achieving the lowest possible intake temperatures. Each component has been designed to give the turbo a smooth and clear flow path. The restrictive standard intake pipe with a diameter of 73 mm is replaced by an intake pipe with a larger diameter of 94 mm. The filter itself has an outer diameter of 192mm or 7.5? with a filter area of over 110,000mm^2. The patented Venturi housing is designed to provide the largest possible internal volume for the space available in the Golf engine bay and provides laminar flow to the turbo pipe. Finally, the duct seals the filter opening at the windshield, but is not restricted by the stock intake alone. The resulting system can significantly outflow the stock airbox while keeping intake temperatures to a minimum with the sealed design. Dyno testingOur MK8 Golf intake has been independently tested by a renowned tuner in the UK, Regal Autosport. A MK8 Golf R was tested in original condition and with a tuning box. The tests were carried out on the same day, with the standard airbox being tested first and then the Eventuri. No other changes were made to the car. The first graph shows the results with a stock map. As you can see, there is a measurable gain across the rev range of up to 12 hp. This gain is noticeable even in a standard vehicle on the road due to better throttle response and faster acceleration. The tuning box was used for both the stock airbox and the Eventuri intake without any changes being made between tests. With a higher flow requirement, the stock airbox places a greater restriction on the turbo, which is evident by the significant gain achieved with the Eventuri fitted. We now have a power increase of up to 20 hp and 30 Nm across the entire rev range, which is even more noticeable on the road. We expect the gains to be even greater with higher tuning levels. The improvements are due to a combination of reasons:1) The closed system keeps IAT levels low - the Golf's engine bay can heat up very quickly, so an open cone filter leads to an increase in IAT levels and therefore a loss of power.2) The Venturi housing provides a smooth transition from the filter to the intake pipes, both of which are matched to an internal diameter of 94mm. This contributes to a more efficient operation of the turbo.3) The entire system is made of pure pre-impregnated carbon fiber, which provides excellent insulation against heat and has smooth inner surfaces, unlike fiberglass, which has sharp resin lines.
