- Performance Gain (Stock Golf R): 10-13hp, 12-15Nm
- Performance Gain (Tuned Golf R): 15-20hp, 25-30Nm
The MK8 Golf GTi/R intake is a complete redesign of the stock intake all the way to the turbo inlet. Taking cues from our RS3 intake, we have maximised usage of the available space to create an intake which can cater for all power levels from stock to high power builds with hybrid or full frame turbos. 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 restrictive stock 73mm diameter inlet tube is replaced with a larger 94mm diameter tube intake tube. The filter itself has an outer diameter of 192mm or 7.5″ with a filtration surface area of over 110,000mm^2. The patented Venturi housing has been designed to provide the maximum internal volume possible for the Golf 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.
The Eventuri Difference
The 2.0 TFSi Generation 4 Eventuri system uses our Patented Carbon fiber 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.
The image above shows the components for the Golf R system. The GTi has a different silicon hose.
The Eventuri MK8 Golf R/Gti intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fiber Patented Venturi Filter Housing with 94mm Outlet
- Bespoke High Flow Dry Cone Filter
- Carbon Fiber Inlet Duct - Full Width
- Silicon tube with 94mm inlet diameter
- Machined breather adapter (Golf R only)
- Secondary Breather Filter and Bracket (USA spec Golf GTi)
- Laser Cut Stainless Steel Brackets
PATENTED TECHNOLOGY
The MK8 Golf housing comprises of a bespoke high flow filter, aluminium cowl, laser cut bracket and the carbon pod itself. The carbon pod shrouds the reverse mounted filter and smoothly shape the airflow down to the intake tubes. 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 patented design and a regular intake system. Further details can be read in the Technology page.
BESPOKE CONE FILTER
In order to achieve the highest flow rate possible we designed a new filter element to make as much use of the space available in the engine bay as possible. This new filter has an outside diameter of 192mm or 7.6" and when flow tested with a housing using a 4" opening is able to flow up to 900 CFM at 28" H2O. The filter medium is ISO tested to ensure that filtration is in line with OEM standards and is also dry. The filter is constructed with our signature flow cones to aid in the Venturi housing principle.
CARBON DUCT
The duct channels ambient air from the slam panel area to the filter housing. It fits inside the OEM slam panel area and smoothly transitions to the circular filter housing shape. In order to ensure a good seal against engine bay heat - it also has a flexible rubber edging around the opening which presses against the filter housings creating the desired seal yet allowing the housing to move with the engine. Since this was designed to support high power builds, we found that the stock openings in the slam panel could cause a restriction at high flow demand. So we lifted the top surface of the duct and created an opening above the slam panel which is able to draw in cold air from behind the hood shut. This extra opening is equivalent to a hole with a diameter of over 7" and completely de-restricts the stock cold air feed. The duct was designed to have the maximum internal volume possible within the given geometry of the engine bay. This ensures that the filter housing is able to draw with minimum restriction.
SILICON TURBO HOSE
Image shows the Golf R hose. GTi hose does not have the secondary breather inlet.
Our silicon hose replaces the stock flexible tube to the turbo inlet. This has been made to match the outlet diameter on our filter housing at 94mm which is significantly larger than the stock tube at 73mm diameter. This represents an increase in cross sectional area of over 60%. The silicon hose retains this diameter as far as possible and then smoothly tapers downs to the stock turbo inlet.
The complete system comes together to provide an intake which improves on the stock airbox in performance, aesthetics and sound.........
