What kind of dividends does the new design pay? Well, fortunately Benzboost member @MR747 tested it out on his stock internal C63 M156.
The result is another 40 wheel horsepower on a very, very, VERY conservative Dyno Dynamics dynamometer in Shoot_8F mode:

You see gains throughout the entire curve. A very nice increase in efficiency.
This is on the same 67mm pulley as before and 98 RON pump fuel.
What will it do with more boost on race gas? Well, we'll have to wait on @MR747 to find out.
