Modifying Superchargers Was Invented and Perfected by Dyno Bob. Why Even Consider Using an Imitation? 

 After 40 years of Engine Air Flow research, Dyno Bob and team have taken SVT Cobra porting to a whole new level.  Born from experience, commitment, and a serious need for speed, the Stage 8 Plus has arrived. The Stage 8 Plus Port provides a 100 RWHP gain, making it a groundbreaking value in the industry. With over 5,000 ported and polished blowers for all different makes and models, we have the experience and dedication to take you to the next level.

Designs are constantly being tested and updated to assure you the largest HP gains available guaranteed. All of our airflow test data was recorded using an XF1000 Supercharger Flow bench. The rotors are profiled, blueprinted and timed to the case. After porting all gasket surfaces are checked for flatness and machined if necessary. The machined parts are put through a three phase cleaning process. The last phase consisting of a high pressure 190 degree rotisserie wash. All superchargers are assembled with factory full synthetic grease and oil. All fasteners are torqued to spec. After final assembly the superchargers are spun at speed and checked with an amplified hearing system to ensure you of a perfect assembly. In addition all superchargers are cataloged, numbered and dated.
