Replace the original supercharger pulley on your CTS-V or ZL1 with one of our precision-made overdrive units to make as much as 3.5-4.5 pounds of additional boost for more more horsepower and torque.
Our LSA supercharger pulleys are one-piece units CNC-machined from high grade steel.  The center bore is sized for the appropriate interference fit and no pinning or drilling is necessary for installation.  The finished pulley is powdercoated in a semi-gloss black for long lasting surface protection.
We recommend the installation of our MIP-100V idler pulley (listed elsewhere in this section) on applications using overdrive (smaller) supercharger pulleys.
Image 5 (above) shows this 2.50" supercharger pulley installed with our MIP-100V supercharger idler and our crank pulley kit.  This image is courtesy of Jason at Aspire Performance and is of the shop's 740 RWHP ZL1 Camaro.
Note 1:  A shorter supercharger belt is necessary when the 2.50" overdrive supercharger pulley is installed.  The Gates or NAPA 080653 in the premium Greenstripe line, is recommended.  If this pulley is installed in conjunction with our MIP-100V idler and the 9.55" pulley ring, a 68.5" belt is recommended.
Note 2:  The end of the supercharger shaft on the LSA application is not threaded like it is in other applications, so a standard pulley removal and installation tool cannot be used.  The supercharger snout must be removed from the supercharger case and the original pulley must be removed and the new pulley installed using a press.  No gaskets need to be replaced and generally no lubricant is lost during this procedure.  As part of this changeover, we highly recommend replacing the original snout isolator, which is problematic and prone to make noise.  Our solid isolator is precision-machined from very high grade materials and installs as a direct replacement for the original.
