Stage 1 ECU tunes are great, but to extract real power from your 3.0T, upgraded pulleys are your best choice. Spinning the stock Eaton TVS1320 supercharger faster (also known as overdriving) yields increased boost throughout the RPM range, resulting in increased horsepower and torque across a wide powerband when paired with an appropriate Stage 2 tune.\u003c\/p\u003e\n\u003cp\u003eCheck out our dyno graph to see the results of our overdrive crankshaft pulley upgrade! After installing our ECS 57.6mm Supercharger Pulley, we found maximum gains of 64 WHP and 53 WTQ​ with an IE stage 2 tune. Once we installed our Overdrive Crank Pulley in combination with the Supercharger Pulley, we had tremendous gains of 98 WHP and 95 WTQ!\u003c\/p\u003e\n\u003cp\u003eOur pulleys were carefully designed, engineered, and tested in-house to ensure we bring you the highest quality product available.\u003c\/p\u003e\n\u003cp\u003eFEATURES\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOverdrives the supercharger without overdriving other accessories\u003c\/li\u003e\n\u003cli\u003e187.3mm effective diameter\u003c\/li\u003e\n\u003cli\u003eStandardized SAE J1459 groove shape\u003c\/li\u003e\n\u003cli\u003e6061-T6 billet aluminum construction with cutouts for lightweight durability\u003c\/li\u003e\n\u003cli\u003eType III anodized for corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003eRetains factory crank pulley damper for accessory drive\u003c\/li\u003e\n\u003cli\u003eExtended Hardware included\u003c\/li\u003e\n\u003cli\u003eIncreases the supercharger drive ratio from 2.56 to 2.96 with the OEM supercharger pulley\u003c\/li\u003e\n\u003cli\u003eCombined ratio with the ECS 57.6mm Supercharger Pulley is 3.25\u003c\/li\u003e\n\u003cli\u003eCompatible with most Stage 2 ECU tunes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNOTE: A compatible Stage 2 (or higher) tune is required for use.
