Edelbrock E-Force Universal Head Units

Edelbrock E-Force Universal Head Units use Eaton R2650 rotors. This is a front drive, front inlet, blow-down style supercharger housing intended for universal and custom applications. The high twist, 4-lobe R2650 rotor design is 15 percent larger than the TVS 2300 and features several improvements to maximize efficiency and performance at upper rpms. Improvements and advantages of R2650 rotors over R2300 rotors: * 170 degree twist (verses 160) * Better sealing with optimized length-to-diameter ratio * Increased durability with larger bearings and timing gears * Pressure relief ports in bearing plate for reduced input power * 4 percent more efficient * 15 percent larger displacement * 18 percent less input power required * 25 percent more airflow at 18,000 rpm and 14 psi boost (2.0 pressure ratio) Show Less
