About Our Ported Superchargers:
After 25 years of Engine Air Flow research Bob Stiegemeier applied his studies to the advancement of air flow threw a supercharger to come out with his Stage 6 Port. The Stage 6 Port has an average gain on 10% RWHP and has rapidly become a popular Engine Modifaction. With over 4,000 Ported and Polished Blowers for all different Makes and Models to date we have the experience and dedication to take your air flow need to the next level.
What do we do with the supercharger after it arrives:
We disassemble your blower and inspect for common problems like:
- Rotor/case wear
- Front drive shaft alignment
- Front drive coupler
- Flaking and tip scoring
- Bypass valve operation
- Broken bolts and stripped threads
The blower case is then ported achieving the CORRECT balance of low pressure to high pressure. (Low pressure meaning the inlet side and High pressure meaning the exit side.) Careful attention is paid to ALL areas to achieve the highest airflow rates and still retain case rigidity. 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 correct 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.
