Eventuri VW Golf MK7 Intake

Info

The VAG 2.0 TFSi Eventuri intake has been developed to provide the most efficient and direct airflow path to the turbo. By replacing the OEM our Patent Pending Venturi housing and coupling this with a smooth duct, we have ensured that the airflow remains as laminar as possible. Furthermore, the addition of a true cold air feed by adding a scoop to the front grill results in the lowest possible inlet air temperature. The result is an optimized intake system which delivers noticeable performance gains consistently.

Product Details

The Eventuri Golf 7 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards.

Each intake system consists of:

• Prepreg Carbon Fiber Venturi Housing
• High Flow Double Cone Air Filter
• Aluminum Cowl for smooth airflow entry
• Prepeg Carbon Fiber Intake Duct (also available in plastic)
• Laser Cut Cold Air Scoop with Surround
• Laser Cut Stainless Steel Brackets
• Laser Cut Slam Panel Plate

Carbon Intake Housing and Duct

The filter housing comprises of a high flow filter, aluminum cowl, laser cut bracket and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow down to the intake tube. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack – below is a diagram to show the comparison between our patent pending design and a regular intake system. Further details can be read in the Technology page. The duct channels cold air from the slam panel opening to the filter. By designing the duct to smoothly transition from the rectangular opening at the front to the circular opening for the filter, it allows the airflow to remain as direct and smooth as possible.

Single Duct VS Double Duct

During the development of our system we designed and tested both the single duct and also an extended double duct version:

Testing showed that the double duct did not produce more power, in fact we could not achieve the same results as we did with our single duct design. This is because the single duct allows for the smoothest and most direct airflow path to the filter and the cross sectional area of the opening is not restrictive for this engine. With the scoop directly in front of the opening there is no chance for warm air to mix with the airflow. Furthermore on the double duct, the airflow has to travel at almost a 90 degree angle from the far side of the grill to then enter the filter housing. A dyno graph comparing the single and double duct can be seen in the Performance tab.

Cold Air Scoop

A key feature of our system is the addition of a scoop into the grill which opens up a direct path for cold air to enter the duct. When the bonnet is closed, it prevents a direct air feed to the duct and the only path for cold air to enter is the small gap between the closed bonnet and the top of the grill – or the small slits on the other side of the grill. This means that the intake will draw some air in from the hot engine bay area. With our scoop system – when the car is in motion there is minimal chance for hot air to enter the intake and so the intake temperatures are lower than the OEM airbox. Here is a thermal imaging video of the engine bay showing how cool the intake system is after a good drive.

Dyno Testing

The standard airbox is cuboid in shape which gives rise to turbulence and increases the drag on the turbo as a result. Furthermore it draws air from a duct, which despite extending over the entire grill is in fact only open on one side and this opening is also facing the engine so the airbox draws in warm engine bay heat. In addition, when the bonnet is closed, the only direct path for cold air is from the small slots in the top of the grill (for the Golf 7 variants).

The following dyno graphs show the before and after results on a Golf 7 R which already had a remap. So both the stock airbox and the Eventuri were tested with the same remap in place. All tests were carried out back to back on the same day with the BONNET CLOSED ON ALL OCCASIONS.

Independent Dyno Test BR Performance from Belgium have tested this intake on a stage 1 tuned Clubsport using their in-house dyno and the intake achieved a 19HP gain:
