Performance Gain Stage 1 Map*: 25-28hp, 20-23ft-lb

Our 4.0TFSI V8 EA825 intake is a ground-up redesign and optimisation of the entire air inlet track. Every component including the lid has been developed to allow the V8 twin turbos to pull in air with less drag resulting in industry leading performance gains. The stock airbox lid itself creates a restriction on the size of the flow collector which feeds the inlets from the filters. So we increased the height of the central section of the lid to allow for a larger flow collector and larger cone filters to be used. This removes the inherent restriction and sets our intake apart from the rest of the field who by utilising the stock lid must also use a restricted collector and filtration media. The turbo inlets are up to 43% larger in cross sectional area than stock and are designed with an advanced dimpled inner surface to reduce frictional losses between the flow and the wall boundary. By allowing a “cushion” of air at the wall surface, airflow is able to move through the inlets at higher flow rates with reduced pressure loss. This allows the turbos to draw air with less resistance and therefore reduce the wastegate duty cycle resulting in higher overall performance.

*Gains measured can vary with different ECU tunes.

 

What's Included

The Eventuri 4.0TFSI V8 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:

  • Enlarged Carbon Fiber AIrbox Lid
  • Carbon Fiber Flow Collector
  • 2 Thermoplastic Turbo Inlets with Dimpled Inner Surface
  • 2 x Bespoke High Flow Dry Cone Filters
  • Custom Flexible Hoses
  • CNC Machined Breather Ports and Reinforcement Rings

 





ENLARGED AIRBOX LID



The first constraint we had to overcome in order to dramatically increase the overall volume of the intake was the airbox lid. The stock lid leaves a shallow opening for the flow collector and also restricts the filtration medium being used. By creating a raised portion in the middle of the lid we are able to create more space for a larger flow collector and also for larger filters. The lid is made from prepreg carbon fibre and uses the same mounting points as the stock lid.





CARBON FLOW COLLECTOR & FILTERS



Directing the airflow from the filters to the turbo inlets is the flow collector. The stock one is constricted in size due to eth stock kid but having removed that restriction, we were able to dramatically increase the volume of our version. In addition, this also gave us the freedom to replace the stock filter with higher flowing cone filters which also have a larger total surface area.





TURBO INLETS



The biggest restriction in the stock system are the turbo inlets. The stock inlets not only are small in size but they also have 2 flexible sections. The flexible section immediately in front of the turbo creates turbulence as the engine moves under acceleration. To combat this, the stock inlets also have flow guides at the exit of the inlets but these also create a restriction. We removed the first flexible section which also meant that we could increase the internal volume. By increasing the inlet sizes, the turbos are able to pull in air with less restriction hence allowing for a quicker spool. In the following photos you can see the differences in the sizes.



We could have finalised the designs here however, we wanted to push the boundaries further and introduce a novel dimpled pattern to the inside surfaces. In theory, small dimples can increase the flow rate by reducing the frictional pressure losses through a tube. 



A lot of R&D went into simulating different sizes and shapes until we settled on an optimised version which demonstrated a higher flow rate through the inlets in comparison with a smooth surface. Applying such an intricate was only possible due to the advanced manufacturing technique we employed to make the inlets, where traditional methods would not have given the accuracy required. The dimples create an "air cushion" affect over the surface of the inlet which then allows the main body of air to "slip" with less friction through the body into the turbo. This results in a more even velocity profile in a dimpled tube with the net affect being a higher velocity for the same boundary conditions. Here are the CFD simulations showing the re-circulations in the dimples and the higher velocity in the dimpled tube.


The complete system comes together to provide an intake which improves on the stock airbox in performance, aesthetics and sound.........

Performance Gains

Dyno Testing

This intake has been independently dyno tested by Eurocharged Canada. Tests were done back to back against the stock airbox and several runs were taken with each configuration. The dyno results show a consistent gain throughout the RPM range which can be attributed to the turbos reaching peak boost earlier and with a lower wastegate duty cycle due to the higher efficiency of the intake system. The first graph shows the results on a completely stock vehicle with only the intake being changed between runs. The second graph shows an RSQ8 which had a stage 1 tune and drop in filter as the baseline run. Then the intake was changed leaving the tune as it was. The performance gains on both vehicles translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Israel, Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

LFor both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
