Actuator Turbosmart VIWG for Mini Cooper S Clubman R55 R56 R57
This Improved 'working ratio' is achieved through an increase to the effective surface area of the diaphragm & revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.
Upgrading with the same base pressure as factory, you can expect a broader boost & torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning & recalibration is recommended for optimal performance.
