The F56 MINI Eventuri intake system is another example of our "Total System" principle. It is a sealed system that ensures the turbocharger does not draw hot air from the engine bay but is enriched with a functional hood scoop that draws atmospheric air into the intake duct. This duct has a larger internal volume than the standard version and also draws air from the factory location above the radiator. Combining the sealed system with the air intake hood results in lower intake temperatures than the standard airbox, preventing heat soak, which is a common issue especially with more powerful MINIs. To ensure the smoothest flow, we use our patented filter housing in conjunction with CNC-machined MAF tubing to provide the smoothest flow to the turbocharger.
Eventuri Difference
The F56 MINI Eventuri system utilizes our patented carbon fiber housing, which provides an aerodynamically efficient airflow path from the filter to the turbocharger. It is not just another cone filter with a heat shield but a unique design that induces the Venturi effect and maintains laminar conditions to reduce resistance on the turbocharger. More information on the housing design and its operation can be found HERE.
*The tested JCW model had a stage 2 tune and intake pipe installed. Performance gains were measured with these modifications installed on both the standard intake system and the Eventuri intake system.
Performance Testing
Power Gain: Stage 1 Cooper S on Dyno: 8-15 HP, 15-25 Nm
Power Gain: Stage 2 Cooper JCW on Dyno: 15-27 HP, 20-26 Nm
Dyno tests were conducted on both Cooper S and JCW models. The Cooper S had a stage 1 modification for both the standard intake system and the Eventuri system. The JCW model was equipped with stage 2 modification and downpipe, both for the standard airbox and the Eventuri system. The Cooper S model showed a maximum power gain of around 8 HP and 11 Nm of torque, but achieved greater gains in the mid-range, with 15 HP and 25 Nm of torque, with good gains throughout the rev range. Similarly, the stage 2 JCW model achieved a maximum power gain of 15 HP, but significantly greater mid-range gains, with 27 HP and 26 Nm of torque, with very good performance gains throughout the rev range. These performance gains were measured simply by swapping the standard intake with the Eventuri intake system - all other modifications were present for both the standard and Eventuri systems.
The gains measured on the dyno translate to the road, where there is increased response to partial and full throttle with the car's eagerness to accelerate up to the redline. Tests were conducted on the same consecutive day, and temperatures were monitored to ensure consistency. The car was first tested with the standard intake - hood closed. Then, we left the car on the dyno and installed the Eventuri. The car was then tested again - hood closed. Multiple runs were performed with both configurations to obtain consistent results.
VBox Acceleration Tests
Finally, we conducted road tests of the Stage 1 MINI Cooper S using a VBox device to record acceleration from 60 to 130 mph (also 100-200 km/h). During VBox tests, our test car was equipped with stage 1 modification for all test runs. Tests were conducted on the same road section - again on the same day, to minimize variable factors. The results show that adding just the intake resulted in a reduction of acceleration times from 60 to 130 mph and also from 100 to 200 km/h by about 0.6 seconds, which is a significant change at such speeds.
Summary of acceleration results:
60-130 mph with standard intake = 14.01 seconds
60-130 mph with Eventuri intake = 13.41 seconds
100-200 km/h with standard intake = 11.69 seconds
100-200 km/h with Eventuri intake = 11.27 seconds
Eventuri Mini Cooper Kit
The Eventuri intake system for Mini Cooper F5X series consists of several components designed to perform specific functions and made with the utmost care.
Each intake system consists of:
- Carbon fiber filter housing with Venturi effect
- Specially designed high-flow cone filter made of non-woven dry material mesh
- Carbon fiber intake duct
- Carbon fiber air scoop
- CNC-machined and insulated MAF tube
- Laser-cut stainless steel mounting kit
- High-quality silicone flexible hose
Filter Housing
The filter housing assembly consists of our specially designed Generation 2 filter, aluminum shield, CNC-machined MAF tube, and the carbon fiber or plastic housing itself. The housing surrounds the filter mounted in reverse and smoothly shapes the airflow down to the intake duct. This smooth cross-sectional area reduction induces the Venturi effect, where the airflow accelerates while maintaining laminar conditions. This can be compared to a large conical suction tube - the diagram below compares our patented design to a typical intake system. Our specially designed filters facilitate airflow through the housings and ensure an even velocity profile as the air exits the housings.
MAF Sensor
The MAF tube is CNC-machined with precise tolerances to ensure proper sensor operation within OEM parameters and thus avoid triggering an engine warning code. Since the MAF tube is located near the exhaust manifold, it is exposed to high temperatures and can be heat-soaked. To counteract this, we insulate the tube with a neoprene sleeve, effectively protecting the interior of the tube from high temperatures.
Hood Air Scoop
The OEM intake system draws air from behind the front grille, above the radiator. The openings for drawing atmospheric air are relatively small and therefore can lead to heat soak of the intake, especially in tuned Minis. The factory hood scoop does not directly supply air to the intake, and since the hood already has two cutouts for the scoop, we decided to utilize this feature and redesign the scoop. Our scoop is a direct replacement for the factory part, which fits using the same mounting system. It features two air ramps that direct external air through the existing cutouts in the hood and into the intake duct (see below). As the car accelerates, more air is forced to flow through the duct, keeping intake temperatures to a minimum and avoiding heat soak. The scoop has a redesigned profile with a longer upper surface, which also gives a more aggressive look. Made of 100% pre-pregnated resin carbon fibers, the scoop provides an incredible aesthetic appearance to the vehicle. To further emphasize the aesthetics, we used a V-shaped carbon fiber split to give a symmetrical profile that complements the scoop, which is located in the center of the hood.
By utilizing existing openings in the hood - the ramps on the carbon fiber scoop reach and direct airflow into the duct. Here's the underside of the hood with the scoop installed.
Air Duct Channel
The OEM intake duct only draws air from the back of the front grille and is very shallow above the front panel. We redesigned the duct to allow airflow from the grille and the scoop. Additionally, our duct has a significantly larger internal volume, allowing for freer breathing of the intake system without restrictions. To protect against heat in the engine bay - the duct is equipped with a flexible rubber edge around the holes on the underside of the hood, which seals against the hood when closed. It also has an expandable rubber edge around the filter housing opening, which provides a good seal for the filter and allows for engine movement.
Water Drainage
To have a direct airflow path to the filter, it is also important to allow water drainage before reaching the filter. To protect against excessive water ingress, we designed several features in the intake components, as follows:
- The top of the scoop covers the openings, preventing rain from entering the duct when the car is stationary.
- The scoop has 2 flow-directing ramps that also act as a water barrier, forcing water to fall to the bottom of the duct instead of directly into the filter area.
- The duct has 2 water drainage holes - above the radiator and also a drain hole before connecting to the filter housing.
- The front of the duct, where it connects to the filter housing, has a wall with a rubber gasket attached to it. This wall prevents water accumulation from directly reaching the filter and the water is drained through an additional drainage hole.
