The core of each system is the Eaton Gen VI 2300 TVS® Supercharger rotating assembly. Eaton's assembly features a four lobe design with 160° of twist for maximum flow, minimum temperature rise and quiet operation for excellent drivability. Purperformance.com likes to point out that the supercharger assembly has been integrated into the intake manifold for a seamless design with minimal components, eliminating the possibility of vacuum leaks between gasket surfaces. Edelbrock's inverted supercharger assembly is uniquely oriented, allowing for an incredible amount of intake runner length for maximizing low end torque. An integrated bypass valve helps eliminate parasitic loss under light throttle for improved mileage potential.
