I’ve been thinking about getting a set of aftermarktet crank and supercharger pulleys. Found a set on eurotoys and looks like it can do quite a bit in terms of responsiveness and HP/Torque, especially with the ECU tune. Has anyone used their stuff and any regrets? Since the crank and supercharger pulleys are larger and smaller, respectively, the super charger is spinning at a much faster rate, does that exceed its max RPM? Any issues with over heating?
