With so many aftermarket intakes available,Â the natural question arises:
â€śSo whatâ€™s so special about the Eventuri Intakes?â€ť
There are twoÂ main elements in explaining the answer to what sets us apart from the rest:
The Patented Eventuri filter housing design
Our Bespoke Filters
Our emphasis on creating a â€śComplete Solutionâ€ť
The Patented Eventuri Filter Housing
Even at first glance the Eventuri intake looks very different to many other aftermarket intakes. Unlike the majority of intakes, which use the same cone filter/tube/heat shield configuration, the Eventuri design is fundamentally different and has been Patented.
AFTERMARKET INTAKE SYSTEMS
Most aftermarket intakes use a cone filter mated to an inlet tube with some type of heat shielding. In this configuration airflow must negotiate a path from the large diameter at the base of the filter through to the smaller diameter of the inlet tube in a relatively short distance. There is usually a velocity stack at the base of the filter to help with the transition, however the stack is usually small. This sudden transition in geometry is detrimental for flow. The result is a loss of throttle response and performance gains are usually limited over the OEM intake system. The diagram below shows a typical aftermarket intake using a cone filter secured to an engine inlet tube. The filter uses a standard velocity stack, which has been highlighted in yellow.
THE EVENTURI INTAKE SYSTEM
The Eventuri is a new type of intake design, which has been granted a patent. We use a cone filter â€“ but here it is inverted and decoupled from the inlet tube. By removing the direct connection between the filter and the inlet tube, the filter is no longer dictating the shape of the airflow. This is now being done by the carbon housing, which is designed to smoothly guide the air into the inlet tube without a sudden change in geometry. This means that we keep laminar conditions throughout the intake, which is a lot more efficient. Furthermore, the funnel-shaped housing invokes the Venturi effect where the smooth reduction in cross-sectional area along the length of the housing causes the airflow to increase in velocity. Essentially the entire housing acts as a large velocity stack. On the road this translates to more power with a smoother delivery as well as sharper throttle response since the airflow is not inhibited by abrupt geometry changes andso is more likely to remain laminar. The diagram below shows an Eventuri intake system using a reverse mounted filter inside an Eventuri housing. The large velocity stack area is highlighted in yellow.
Eventuri Bespoke Filters
To compliment our unique filter housings we designed our filters specifically for this reverse mounted configuration in order to provide the optimum airflow through the system. Detailed descriptions of the filters can beÂ seen in the FILTER section.
The Complete Solution
The final element to our design â€“ which is as important, is our emphasis on creating a complete solution. We dedicate a lot of design effort on ensuring the filter housings are provided with ambient air in the most efficient way possible. Allowing the filters to draw in heated air from the engine bay defeats the objectiveÂ and in many cases is the cause of an actual loss in power over the stock system once the engine bay is heat soaked. Simply using heat shields is not enough â€“ there must also be a method ofÂ channelingÂ cold air into the intake. This is where we have seen some companies use â€śscoopsâ€ť but on closer inspection are usually very flat and almost perpendicular to the oncoming air. Not the ideal solution for trying to redirect air at high speeds! Our scoop designs have, where possible a curved face for as much of the exposed area as possible in order to smoothly redirect incoming air to the filters. In doing so we ensure that engine bay heat is displaced and so intake air temperatures are kept as low as possible.
From scoop to duct to housing to inlet tubing â€“ by utilizing organic shapes, we invest a great deal of time and effort in providing a smooth path for the airflow to follow. Hence ensuring maximum efficiency of the system.
On The Road
With a smooth inlet track to the MAF tube/Engine inlet and by ensuring we have an effective cold air supply to the filters, the resultant performance increases translate to an enhanced driving experience:
Throttle response is sharper as air speeds in the inlet track are maintained by the Venturi effect.
Low/mid range torque is increased which improves general driveability. The car feels more aggressive and eager to drive.
Top end power is increased as the engine is allowed to draw in cold air with less restriction.
Couple the performance increase with a more audible and sonorous induction sound and the overall driving experience is much more involving and enjoyable.
