Katech C6 ZR1 Corvette Stage 2 750HP Installed Performance Package
750 HP Supercharged LS9 Performance with Katech-Ported Supercharger and Snout, GripTec 2.6-Inch Pulley, ATI Supercharger Drive Upgrades, and Professional Dyno Tuning!
750 HP Supercharged Performance for the Legendary C6 Corvette ZR1
The Katech C6 ZR1 Corvette Stage 2 750HP Installed Performance Package is engineered for owners looking to extract substantially more performance from Chevrolet's legendary supercharged 6.2L LS9 V8. Combining precision supercharger porting, upgraded induction components, enhanced supercharger drive hardware, additional fuel injector capacity, and professional engine calibration, Stage 2 delivers a comprehensive performance upgrade rated at 750 engine horsepower.
At the center of the Stage 2 package is Katech LS9 supercharger porting and supercharger snout porting. These modifications are designed to improve airflow through the factory supercharger assembly, reducing restrictions in the induction path and supporting the increased airflow demands of the upgraded supercharger drive system.
A Katech CNC-ported LS9 throttle body further improves airflow into the supercharger. The combination of the ported throttle body, ported supercharger snout, and ported supercharger creates a coordinated induction upgrade while retaining the factory LS9 supercharger architecture.
The package includes a GripTec 2.6-inch supercharger pulley, ATI LS9 damper, ATI LS9 balancer/lower pulley, and Gates HD supercharger belt. These components work together to support the upgraded supercharger drive configuration. GripTec's specialized pulley surface is designed to improve belt traction and help reduce unwanted belt slip under load.
To support the increased performance demands, Stage 2 includes FIC 850cc fuel injectors and NGK BR7EF spark plugs. The upgraded injectors provide additional fuel delivery capacity, while the spark plugs are selected for the performance requirements of the modified supercharged LS9.
An AttackBlue high-flow air filter and 160-degree thermostat complete the listed induction and cooling upgrades. Professional installation, baseline chassis dyno testing, HP Tuners credits, chassis dyno tuning, and street drivability calibration are included to refine the completed package.
Stage 2 also includes a Katech serialized Stage 2 plaque and a Katech 1-year / 12,000-mile limited warranty, subject to applicable warranty terms and conditions.

Is This Package Right for You?
The Katech C6 ZR1 Stage 2 750HP package is designed for owners seeking a significant increase in supercharged LS9 performance without replacing the factory supercharger or modifying the engine's internal components.
Where Stage 1 focuses primarily on supercharger pulley and induction upgrades, Stage 2 goes further by addressing airflow restrictions within the factory supercharger assembly itself. Katech's supercharger and snout porting, combined with the CNC-ported throttle body, improve the induction path and support the increased airflow requirements of the upgraded supercharger drive system.
The addition of FIC 850cc injectors provides increased fuel delivery capacity, while the ATI damper and lower pulley, Gates HD belt, and GripTec pulley support the higher-performance supercharger drive configuration.
For enthusiasts looking for stronger acceleration, increased horsepower, and a more aggressive supercharged driving experience while retaining the factory LS9 engine architecture, Stage 2 offers a comprehensive installed performance solution.

The Katech Installation Process
Vehicle Inspection and Baseline Dyno
Before modifications begin, the vehicle is evaluated for existing mechanical concerns, previous modifications, and conditions that may affect installation or calibration. Baseline chassis dyno testing documents the vehicle's incoming performance and provides a reference for evaluating the completed Stage 2 package.
Katech LS9 Supercharger Porting
The factory LS9 supercharger receives Katech's porting service to improve airflow through the supercharger assembly. This precision machining is designed to reduce airflow restrictions and support the increased demands of the upgraded supercharger drive configuration.
Katech LS9 Supercharger Snout Porting
The LS9 supercharger snout is ported to improve the airflow path entering the supercharger. This modification complements the supercharger porting and CNC-ported throttle body, creating a more efficient induction path through the factory supercharger assembly.
Katech CNC-Ported LS9 Throttle Body
The factory LS9 throttle body receives Katech CNC porting to improve airflow through the throttle body opening. The modified throttle body works with the ported supercharger snout and supercharger assembly to support the Stage 2 performance combination.
GripTec 2.6-Inch Supercharger Pulley Installation
A GripTec 2.6-inch supercharger pulley is installed to increase supercharger drive speed compared with the factory configuration. The GripTec pulley features a specialized traction surface designed to improve belt grip and help reduce unwanted belt slip under load.
ATI Damper and Lower Pulley Installation
The package includes an ATI LS9 damper and ATI LS9 balancer/lower pulley. These components are installed as part of the upgraded supercharger drive configuration, supporting the pulley combination used to achieve the Stage 2 performance target.
Gates HD Supercharger Belt Installation
A Gates HD supercharger belt is installed to support the upgraded drive system. The heavy-duty belt works with the GripTec pulley and ATI lower pulley configuration to transfer engine power to the supercharger.
AttackBlue High-Flow Air Filter Installation
The AttackBlue high-flow air filter is installed to support improved induction airflow into the supercharger. The filter complements the ported throttle body, snout, and supercharger assembly.
FIC 850cc Fuel Injector Installation
The factory fuel injectors are replaced with FIC 850cc injectors to provide additional fuel delivery capacity. These injectors support the increased fuel demands of the Stage 2 supercharged LS9 configuration and are incorporated into the engine calibration.
NGK BR7EF Spark Plug Installation
NGK BR7EF spark plugs are installed as part of the ignition system preparation for the higher-output supercharged engine configuration.
Cooling System Service
A 160-degree thermostat is installed, with GM Dex-Cool coolant included for the associated cooling system service. The thermostat changes the temperature at which coolant circulation begins but does not independently guarantee a specific operating temperature.
Wideband Tuning Preparation
The included wideband O2 bung, plug, and washer provide provisions for wideband oxygen sensor use during the tuning process.
HP Tuners Calibration
Using HP Tuners software and included credits, Katech calibrates the LS9 engine management system for the upgraded supercharger drive configuration, increased airflow, FIC 850cc fuel injectors, and other Stage 2 modifications.
Chassis Dyno Tuning
The vehicle receives chassis dyno tuning to evaluate engine performance and refine the calibration. Dyno testing allows Katech to assess the completed package and compare performance against the baseline results.
Street Drivability Calibration
Following dyno tuning, the vehicle receives street calibration to refine throttle response, part-throttle operation, and general drivability. The goal is to deliver responsive supercharged performance while maintaining predictable operation during normal driving.
The Katech Difference
Katech Engineering has been developing, machining, assembling, and validating high-performance engines and components since 1977. From professional motorsports programs to premium street performance packages, Katech focuses on complete engineered systems rather than random combinations of parts.
The Stage 2 750HP package combines Katech's supercharger machining capabilities, carefully selected induction and supercharger drive components, upgraded fuel injectors, professional installation, and calibration to deliver a comprehensive LS9 performance solution.
Rather than relying on internal engine modifications, Stage 2 focuses on improving the efficiency and performance potential of the existing factory-supercharged LS9 configuration through precision porting, upgraded supercharger drive hardware, and professional calibration.
Recommended Upgrades
For owners interested in additional horsepower beyond the Stage 2 package, Katech offers further performance solutions for the supercharged LS9 Corvette platform. Contact a Katech Performance Specialist to discuss available cooling improvements, fuel system modifications, exhaust upgrades, and higher-performance package options.
Additional components and services are not included unless specifically listed in the package contents.
