Katech Engineering offers precision CNC porting services for the Lingenfelter LS9 supercharger snout, engineered to improve inlet airflow and throttle body transition for high-output LS9 applications. This service is specifically designed for compatibility with Katech or Nick Williams 103mm throttle bodies, ensuring proper alignment, smooth airflow, and repeatable performance.
All CNC porting is performed in-house at Katech Engineering in Clinton Township, Michigan, using race-validated CNC programs developed from real competition and durability testing—not generic hand-blending.
