The F56 MINI Eventuri intake system is another example of the “Complete System” principal. It is a sealed system which ensures that the turbo does not draw hot air from the engine bay but enhanced with a functional bonnet scoop which forces ambient air into the intake duct. This duct has a larger internal volume than the stock version and also draws air from the stock location above the radiator. The combination of a sealed system with an air scoop results in lower intake temperatures than the stock airbox and avoids heat soak which is a common issue especially on higher powered MINIs. To ensure the smoothest flow possible we use our Patented filter housing coupled with a CNC machined MAF tube to ensure the smoothest possible flow to the turbo.
The Eventuri Difference
The F56 MINI Eventuri system uses our Patented Carbon fibre Housing which provides an aerodynamically efficient airflow path from the filter to the turbo. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect and maintains laminar flow conditions to reduce the drag on the turbo.
* The JCW tested had a stage 2 map and downpipe. Performance gains measured with these modifications fitted for both stock airbox and Eventuri.
Performance Gain : Stage 1 Cooper S Dyno: 8-15hp, 15-25ft-lb
Performance Gain : Stage 2 Cooper JCW Dyno: 15-27hp, 20-26ft-lb
Dyno tests were carried out on both a Cooper S and a JCW. The Cooper S had a stage 1 remap for both the stock airbox and the Eventuri. The JCW had a stage 2 remap and downpipe for both the stock airbox and Eventuri. The Cooper S showed a peak gain of approximately 8hp and 11ft-lb of torque but higher mid-range gains of 15hp and 25ft-lb of torque with a good gain through the RPM range. Similarly the stage 2 JCW saw peak gains of 15hp but much higher mid-range gains of 27hp and 26ft-lb of torque with a very good increase in performance throughout the RPM range. These performance gains were measured after only changing the stock airbox for the Eventuri intake - all other modifications were present for both the stock airbox and the Eventuri intake.
The gains measured on the dyno translates on the road to increased part throttle and full throttle response with the car pulling much more eagerly to the redline. The testing was done on the same day back-to-back and temperatures were monitored to ensure consistency. The car was tested firstly with the stock intake - hood closed. We then left the car on the dyno and installed the Eventuri. The car was then run again - hood closed. Several runs were carried out with both configurations to get a consistent result.
