Using Patent Pending filter housings, Eventuri are setting a new benchmark in the aftermarket intake industry. No more unverified and misleading performance gains, Eventuri is consistently developing bespoke intake solutions which bring genuine power and torque increases. Extensive prototyping, testing and rigorous validation methods ensure Eventuri designs enhance the driving experience of your vehicle in the real world. With a construction quality that is second to none – Eventuri is raising the bar on every front.
On first glance the Eventuri intake may look similar to the majority of aftermarket intakes out there however, unlike the majority which use the same cone filter/tube/heat shield configuration, the Eventuri design is fundamentally different. To appreciate the difference we will firstly look at the conventional cone filter intake design:
Most aftermarket intakes use a cone filter mated to the engine inlet tube (usually with the Air Mass sensor ie. MAF tube) and have some sort of heat shield surrounding the cone. In this configuration – the airflow has to negotiate a path from the large diameter at the base of the filter through to the smaller diameter of the MAF tube in a relatively short distance. There is usually a velocity stack at the base of the filter to help the transition however, this is also relatively short. The sudden transition in geometry is detrimental for airflow as turbulence and dead spots arise – particularly in the low/mid RPM range as flow starts to develop (transient phase). This results in a loss of low/mid range torque as flow velocity through the “less restrictive” filter is impeded. The seldom gains in power only surface in the last few hundred RPM range and even then do not live up to the claims.
The Eventuri is a new type of intake design which is patent pending and this is why: We use a cone filter – BUT here it is inverted and decoupled from the MAF tube. By removing the direct connection between the filter and the MAF tube, the filter is not now dictating the shape of the airflow. This is now being done by the carbon housing, which also acts as a heat shield. The carbon housing shapes the flow smoothly down to the MAF tube over the entire distance of the housing. This means that we keep laminar conditions throughout the intake into the MAF tube 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 velocity stack. On the road – this translates not only to more power but smoother delivery and a sharper throttle response as the airflow is not inhibited by abrupt geometry changes and so is more likely to remain laminar.
The second element to Eventuri’s design – which is as important, is their emphasis on creating a complete solution. Eventuri 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 objective 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 – there must also be a method of channeling cold air into the intake. This is where Eventuri has seen some companies use “scoops” 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! Eventuri 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 Eventuri ensures 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 – by utilizing organic shapes, Eventuri invests a great deal of time and effort in providing a smooth path for the airflow to follow. Hence ensuring maximum efficiency of the system.
Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. After owning various intakes over many years for their own cars and being disappointed with the gains which seldom lived up to their claims – the founders decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures.
Eventuri systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing.
Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none.
After many years of disappointment with the usual aftermarket intakes, Eventuri are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve the performance of your vehicle.
