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 inlet leads to lower intake temperatures than the standard airbox and prevents 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 about the housing design and its operation can be found HERE.
*The tested JCW model had a stage 2 map and intake pipe. Performance gains were measured with these modifications installed both in the standard intake system and the Eventuri intake system.
Performance Test
Power Increase: Stage 1 Cooper S on Dyno: 8-15 HP, 15-25 Nm
Power Increase: 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 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 Eventuri system. The Cooper S model showed a maximum power increase of about 8 HP and 11 Nm of torque, but achieved greater increases in the mid-range, totaling 15 HP and 25 Nm of torque, with good performance increase across the entire rev range. Similarly, the JCW stage 2 model achieved a maximum power increase of 15 HP, but significantly greater increases in the mid-range, totaling 27 HP and 26 Nm of torque, with very good performance increase across the entire rev range. These performance gains were measured simply by swapping out the standard intake for the Eventuri intake - all other modifications were present for both standard and Eventuri systems.
The dyno gains translate to the road, where there is increased response to partial and full throttle driving with a greater willingness of the car to accelerate up to the redline. Tests were conducted on the same consecutive day, and temperatures were monitored to ensure consistency. The car was tested first with the standard intake - hood closed. Then, the car was left on the dyno and the Eventuri was installed. The car was then tested again - hood closed. Multiple runs were conducted with both configurations to obtain a consistent result.
VBox Acceleration Tests
Ultimately, we conducted road tests of the Stage 1 MINI Cooper S using 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. The tests were conducted on the same stretch of road - again on the same day, to minimize variable factors. The results show that adding just the intake resulted in shortened 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 crafted with utmost precision.
Each intake system consists of:
- Carbon fiber filter housing with Venturi effect
- Specially designed high-flow cone filter made of non-woven dry fabric
- Carbon fiber intake duct
- Carbon fiber air inlet
- CNC machined and insulated MAF tube
- Laser-cut stainless steel mounting kit
- High-quality silicone flexible coupling
Cone Filter Housing
The filter housing assembly consists of our specially designed Generation 2 filter, aluminum heat 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 downward into the intake duct. This smooth cross-sectional reduction induces the Venturi effect, where the airflow accelerates while maintaining laminar conditions. This can be likened to a large tapered suction tube - the diagram below compares our patented design with a typical intake system. Our specially designed filters facilitate airflow through the housings and provide 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 engine warning codes. As 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 Inlet
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 inlet does not directly supply air to the intake, and since the hood already has two cutouts under the inlet, we decided to utilize this feature and redesign the inlet. Our inlet is a direct replacement of the factory part, which fits using the same mounting system. It features two air intake 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, maintaining intake temperatures at a minimum and avoiding heat soak issues. The inlet has a redesigned profile with a longer upper surface, which additionally gives a more aggressive look. Made of 100% pre-preg carbon fiber, the inlet provides an incredible aesthetic appearance. To further emphasize the aesthetics - we used a carbon fiber V-shaped split to give a symmetrical profile that blends well with the inlet, which is located in the center of the hood.
By utilizing existing openings in the hood - carbon fiber inlet ramps reach and direct airflow into the duct. Here is the underside of the hood with the inlet installed.
Air Intake Duct
The factory intake duct draws air only from behind the front grille and is very shallow above the front panel. We redesigned the duct to allow airflow from both the grille and the inlet. 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 openings on the underside of the hood, which seals against the hood upon closure. It also has an expandable rubber edge around the filter housing opening, which provides a good seal for the filter and allows movement with the engine.
Water Drainage
To ensure 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 part of the inlet covers the openings, preventing rain from entering the duct when the car is stationary.
- The inlet 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 seal attached. This wall prevents water from accumulating directly before reaching the filter, and the water is drained through an additional drain hole.
