Intakes have always been the most restrictive part of any intake system and we have tested many different options and versions over the years through racing and extensive dyne testing, for quality/ design and power increase there is simply no equal to the intelligent and beautiful Eventuri intake system.
With so many aftermarket intakes available, the natural question arises:
“So what’s so special about the Eventuri Intakes?”
There are two main elements in explaining the answer to what sets Eventuri apart from the rest:
- The Patented Eventuri filter housing design
- Bespoke Filters
- Emphasis on creating a “Complete Solution”
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.
THE EVENTURI INTAKE SYSTEM
The Eventuri is a new type of intake design, which has been granted a patent. We use a cone filter – 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.
The Complete Solution
The final element to our design – 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 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 we have 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! 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 – 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.
JAGUAR F TYPE
Performance Gain: V8: 30-38hp, 30-35ft-lb
Performance Gain: V6: 18-24hp, 20-25ft-lb
The Eventuri Intake system for the Jaguar F-Type fits both the 3.0l and 5.0l supercharged variants. We have replaced the standard airboxes and resonator tubes with our Patent Pending filter housings mated to bespoke carbon fibre tubes. To ensure a smooth airflow path, our tubes are matched in diameter to the stock MAF sensor tubes downstream and then matched again to the engine inlet tubes upstream. The combination of our Eventuri housings and tubes improve the aerodynamic efficiency of the inlet track resulting in significant increase of power and torque. This is a stand-alone upgrade which requires no further tuning.
The Eventuri Difference
The F-Type Eventuri system uses our Patent Pending Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the MAF tube. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
