Here is the top-of-the-range model of Malossi torque converter. The larger diameter allows a broader beach of use, same manner as a larger pinion on a bicycle. But due to the system of variation specific to the scooters, we'll feel a benefit at all RPM. The guides are modified to allow a more linear and rapid opening of the converter. It is preferable to use it with the Malossi ''Over range''  variator and belt.
