If you would prefer not to modify your production supercharger front cover, LPE can supply a
stock GM cover for you to modify or one with the parts already installed.
Read the entire instruction manual before beginning installation. Many of the stock parts will
be used in reassembly.
When referencing the side of the vehicle, the driver side of the vehicle is considered the left
side and the passenger side of the vehicle is considered the right side of the vehicle.
Torque value warning - the torque values for the fasteners are provided in metric (Nm) and
then imperial units. For the imperial units some are referenced in lb-ft and others in lb-in. Make
sure you notice the difference and set your torque wrench correctly.
Aftermarket supercharger pulleys and dampers increase the supercharger speed and airflow,
resulting in increased inlet pressure drop that can cause the factory rubber inlet duct to get sucked
shut under high RPM use. For this reason Lingenfelter Performance Engineering has designed a
replacement air intake system to resolve these potential problems. This is the same air intake that is
included with the Lingenfelter CTS-V LSA supercharger pulley upgrade kit (part # L250070709).
