While upgrading both the crankshaft and supercharger pulleys delivers an impressive bump in power, installation can be a challenge. With our 207mm Crankshaft Pulley Kit, upgrading your supercharger drive has never been easier!\u003c\/p\u003e\n\u003cp\u003eDesigned to increase the supercharger drive ratio without overdriving other accessories, this upgrade increases blower speed and boost pressure to unlock serious horsepower gains. Boasting a 22% increase in supercharger RPM, this pulley supports up to 550 HP when paired with a Stage 2 ECU tune, making it the ultimate solution for enthusiasts looking to maximize power without compromising reliability.\u003c\/p\u003e\n\u003cp\u003eUnlike dual-pulley setups that require multiple modifications and a lengthy installation process, this single overdriven crankshaft pulley delivers greater performance benefits in a simpler package. With increased boost pressure and supercharger RPM, optimized belt engagement, and compatibility with most Stage 2 ECU tunes, our 207mm crank pulley upgrade provides an efficient path to unlocking your engine’s full potential. This pulley bolts directly over the existing crankshaft pulley, eliminating the need to press on a smaller supercharger pulley—saving you time and effort. Unlike smaller supercharger pulleys that can cause belt slippage, this crank pulley upgrade eliminates that risk, delivering consistent and reliable performance. Our 207mm crank pulley upgrade retains the factory crank pulley damper for the accessory drive, preserving the balance and longevity of your engine components.\u003c\/p\u003e\n\u003cp\u003eCrafted from lightweight, single-piece 6061-T6 billet aluminum, this pulley is engineered for maximum strength and durability. Precision CNC-machined cutouts reduce overall weight without sacrificing integrity, and a standardized SAE J1459 groove shape ensures optimal belt engagement. The Type III anodized finish provides superior corrosion and wear resistance, ensuring long-lasting performance in demanding conditions. Extended hardware is included for a precise fit, ensuring a straightforward installation with no special tools required.\u003c\/p\u003e\n\u003cp\u003eBY THE NUMBERS\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOEM B8 S4 Crank Pulley \u0026amp; OEM B8 S4 Supercharger Pulley\u003cul\u003e\n\u003cli\u003e\u003cp\u003eCrank Pulley Diameter: 162.179mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Pulley Diameter: 63.25mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Drive Ratio: 2.564:1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Rotor Speed @ 7200 RPM: 18,462 RPM\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eECS Overdrive Crank Pulley \u0026amp; OEM B8 S4 Supercharger Pulley\u003cul\u003e\n\u003cli\u003e\u003cp\u003eCrank Pulley Diameter: 187.300mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Pulley Diameter: 63.25mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Drive Ratio: 2.961:1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Rotor Speed @ 7200 RPM: 21,319 RPM\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eECS Overdrive Crank Pulley \u0026amp; ECS Supercharger Pulley\u003cul\u003e\n\u003cli\u003e\u003cp\u003eCrank Pulley Diameter: 187.300mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Pulley Diameter: 57.60mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Drive Ratio: 3.252:1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Rotor Speed \u0026amp; 7200 RPM: 23,414 RPM\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eECS 207mm Crank Pulley Upgrade \u0026amp; OEM 63.25mm B8 S4 Supercharger Pulley\u003cul\u003e\n\u003cli\u003e\u003cp\u003eCrank Pulley Diameter: 207.000mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Pulley Diameter: 63.25mm\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Drive Ratio: 3.273:1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eSupercharger Rotor Speed @ 7200 RPM: 23,565 RPM\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePERFORMANCE FEATURES\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreases supercharger drive ratio from 2.56 to 3.27 with stock pulley—a 22% increase!\u003c\/li\u003e\n\u003cli\u003eSupports up to 550 HP with a Stage 2 ECU tune\u003c\/li\u003e\n\u003cli\u003eLightweight 6061-T6 billet aluminum construction with weight-saving CNC-machined cutouts\u003c\/li\u003e\n\u003cli\u003eType III anodized for corrosion and wear resistance\u003c\/li\u003e\n\u003cli\u003eThe standardized SAE J1459 groove shape offers compatibility with the OE belt shape\u003c\/li\u003e\n\u003cli\u003eRetains factory crank pulley damper for accessory drive stability\u003c\/li\u003e\n\u003cli\u003eIncludes extended hardware for a hassle-free install\u003c\/li\u003e\n\u003cli\u003eInstalls over the OEM crankshaft pulley, providing easy installation and ensuring accessories aren't overdriven\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eKIT CONTENTS\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eECS 207mm Crankshaft Pulley\u003c\/li\u003e\n\u003cli\u003eZinc-Plated Hex Head Screw (8)\u003c\/li\u003e\n\u003cli\u003eContinental 1360mm Supercharger Drive Belt\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePRODUCT DEVELOPMENT\u003c\/p\u003e\n\u003cp\u003eOur 3.0T 207mm Crank Pulley Upgrade was designed, engineered, tested, and quality inspected by our Research and Development team at our Wadsworth, Ohio facility.
