Mercedes M271 Pulley upgrade Eaton M65

Smaller diameter pulley for installation on M45 superchargers. By installing the smaller pulley the supercharger makes more RPM resulting in more airflow and boost which can be used to increase horsepower.

The original pulley has a diameter of 72mm, our pulley is 62mm resulting in 16% difference. 

With the smaller pulley installed power output goes up by 30hp. Combined with a software modification this results in nearly 50hp more!
