It is intended for applications where the correct W245 4.0L rotor assembly is required for service, repair, rebuild, or custom supercharger package work.\u003c\/p\u003e\n\u003cp\u003eFor builders developing their own supercharger packages, Whipple twin-screw compressors offer the positive displacement response and broad power delivery needed for serious performance applications. Positive displacement superchargers are widely used because they deliver strong throttle response, excellent drivability, and immediate boost characteristics across a wide operating range.\u003c\/p\u003e\n\u003cp\u003eThe Whipple screw compressor design is built to support both low-boost and high-boost applications, with high adiabatic efficiency levels up to 80% and volumetric efficiency levels up to 99.9%. This helps provide the broad power band, strong low-end torque, and high peak horsepower potential that builders need when developing complete supercharger systems.\u003c\/p\u003e\n\u003cp\u003eWhipple rotor assemblies are available for builders using their own housings or developing custom supercharger packages. Whipple also offers a wide range of screw compressor sizes, drive lengths, pulley combinations, and bypass valve options to support different performance applications.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWhipple W245 rotor assembly\u003c\/li\u003e\n  \u003cli\u003e4.0L rotor assembly configuration\u003c\/li\u003e\n  \u003cli\u003eService or builder component for compatible Whipple supercharger assemblies\u003c\/li\u003e\n  \u003cli\u003ePositive displacement twin-screw design supports immediate boost response and broad power delivery\u003c\/li\u003e\n  \u003cli\u003eAdiabatic efficiency levels up to 80%\u003c\/li\u003e\n  \u003cli\u003eVolumetric efficiency levels up to 99.9%\u003c\/li\u003e\n  \u003cli\u003eUseful for repair, rebuild, replacement, or custom package work\u003c\/li\u003e\n  \u003cli\u003eVerify compatibility with the correct housing and application before installation\u003c\/li\u003e\n  \u003cli\u003eDealer\/Supplier #: WSC-RA245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Whipple Superchargers","offers":[{"title":"Default Title","offer_id":56180567605570,"sku":"WSC-RA245","price":3095.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/6002\/9506\/files\/F198645748.jpg?v=1789511591","url":"https:\/\/whipplesuperchargers.com\/products\/whipple-w245-4-0l-rotor-assembly-wsc-ra245","provider":"whipplesuperchargers","version":"1.0","type":"link"}
