Intake Manifold/Supercharger Assembly
The LSA Roots-type supercharger is a positive displacement pump that consists of 2 counter-rotating rotors installed into the lower intake manifold housing. The rotors are designed with 4 lobes and a helical twist. The rotors of the supercharger are designed to run at a minimal clearance, not in contact with each other or the housing and are timed to each other by a pair of precision spur gears which are pressed onto the rotor shafts. The rotors are supported at each end by self-lubricating non-serviceable bearings. The drive belt pulley is pressed onto the input shaft. The input shaft is coupled to the rotor shaft. Both the belt pulley and torsional isolator are also non-serviceable.
The lower supercharger assembly consists of the following components:
- Lower Intake Manifold Housing, to include rotors, gears, bearings, torsional isolator, and drive belt pulley
- Bypass Valve
- Bypass Actuator
- Charged Air Bypass Valve
- Fuel Rail with Injectors
- Throttle Body Assembly
- Evaporative Emission Canister Purge Valve
- Inlet Air Pressure Sensor
