750 HP Supercharged Performance with CNC-Ported LT4 Supercharger Components!
Professionally Installed and Dyno-Tested Performance for the GM LT4
The Katech C7 Z06 Corvette Stage 2 750HP Installed Performance Package is a professionally engineered performance upgrade designed to deliver 750 horsepower from the factory-supercharged GM LT4 6.2L V8. Building on the Stage 1 performance combination, Stage 2 introduces additional airflow improvements through a Katech billet 103mm throttle body, CNC-ported supercharger base, and CNC-ported supercharger snout, along with an upgraded supercharger pulley system and custom calibration.
At the center of the Stage 2 package is the factory LT4 supercharger, enhanced with Katech CNC-machined components to improve airflow through the induction system. The Halltech STRZ06 intake and Katech billet 103mm throttle body complement the ported supercharger components, while the GripTec 2.3-inch pulley, GripTec hub, and Gates HD supercharger belt support the upgraded supercharger drive configuration.
Designed for C7 Z06 owners seeking more performance without replacing the factory supercharger or modifying internal engine components, this package combines professionally selected hardware, installation, chassis dyno calibration, and street drivability validation into a complete Katech performance solution.

The Katech Installation Process
Vehicle Inspection
Each vehicle is inspected before installation begins to identify any concerns that should be addressed before modification.
Baseline Dyno Testing
Baseline chassis dyno testing is performed before modifications to document incoming vehicle performance and establish a reference point for the completed package.
Professional Installation
All included components are installed by Katech technicians using established installation and assembly procedures. The Halltech STRZ06 intake, Katech billet 103mm throttle body, CNC-ported supercharger base and snout, GripTec supercharger hub and pulley, Gates HD supercharger belt, and upgraded cooling components are incorporated into the complete Stage 2 performance package.
Supercharger Porting and Airflow Upgrades
The factory LT4 supercharger base and snout receive Katech CNC porting to improve airflow through the supercharger assembly. These modifications are designed to reduce inlet restrictions and complement the increased airflow capacity of the Katech billet 103mm throttle body and Halltech STRZ06 intake.
Supercharger Pulley and Belt Installation
The factory supercharger drive configuration is upgraded with a GripTec hub, 2.3-inch supercharger pulley, and Gates HD supercharger belt. The upgraded pulley configuration is designed to increase supercharger speed and boost potential, while the Gates HD belt supports reliable operation of the modified drive system.
ECU Calibration
The package includes the required HP Tuners credits and custom ECU calibration appropriate for the Stage 2 750HP performance combination. Calibration is developed to support the modified induction system, ported supercharger components, upgraded pulley configuration, and overall engine operation under increased airflow and boost.
Dyno Calibration and Validation
Following installation, the vehicle receives chassis dyno calibration and performance validation to verify the operation of the completed package and evaluate performance gains compared to the baseline results.
Street Drivability Calibration
After dyno calibration, the vehicle is road tested and calibrated to verify throttle response, part-throttle operation, idle quality, and overall street drivability before delivery. Calibration is tailored to the increased performance characteristics of the upgraded supercharged LT4 combination.
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 takes advantage of Katech's in-house CNC machining, engine development, professional installation, calibration, and validation capabilities to deliver a complete LT4 performance upgrade.
Every Katech Installed Performance Package is built around professional installation, calibration, validation, and support from the Katech team.

▾ How much horsepower does the Stage 2 package make?
The Stage 2 package is rated at 750 engine horsepower in the specified configuration. Actual output may vary based on vehicle condition, fuel quality, environmental conditions, and other factors.
▾ What vehicles are compatible with this package?
This package is designed for 2015-2019 Chevrolet Corvette C7 Z06 models equipped with the factory-supercharged GM LT4 6.2L V8 engine.
▾ Does this package replace the factory supercharger?
No. The Stage 2 package retains the factory LT4 supercharger while upgrading the supercharger base and snout with Katech CNC porting. The package also adds a Katech billet 103mm throttle body, Halltech intake, and upgraded supercharger drive components.
▾ What is the difference between Stage 1 715HP and Stage 2 750HP?
The Stage 1 715HP package includes a Halltech STRZ06 intake, GripTec supercharger pulley and hub, cooling system upgrades, and calibration. The Stage 2 750HP package adds a Katech billet 103mm throttle body, CNC-ported supercharger base and snout, and Gates HD supercharger belt to further improve airflow and supercharger performance.
▾ What is the benefit of CNC-porting the supercharger base and snout?
Katech CNC porting is designed to improve airflow through the factory LT4 supercharger assembly by optimizing the internal passages. Combined with the larger throttle body and intake system, these modifications support increased supercharger airflow and horsepower potential.
▾ Why does this package use a 103mm throttle body?
The Katech billet 103mm throttle body provides a larger throttle opening to support increased airflow into the modified LT4 supercharger system. It complements the CNC-ported supercharger snout and Halltech intake.
▾ What are the benefits of the GripTec 2.3-inch pulley?
The GripTec 2.3-inch supercharger pulley is designed to increase supercharger speed compared to the factory pulley configuration, supporting increased boost and horsepower potential. Its traction-focused design is intended to improve belt engagement.
▾ Why is a Gates HD supercharger belt included?
The Gates HD supercharger belt is included to support the upgraded supercharger drive system and provide dependable belt performance under increased operating demands.
▾ Does this package require internal engine modifications?
No. The Stage 2 package focuses on intake, throttle body, supercharger porting, pulley, belt, cooling system, and calibration upgrades without requiring camshaft or cylinder head modifications.
▾ Will my C7 Z06 sound different after installation?
The Halltech STRZ06 intake and upgraded supercharger pulley may increase induction and supercharger sounds compared to the factory configuration. Since the factory camshaft is retained, idle characteristics will generally remain closer to stock than a camshaft-equipped package. Exhaust volume will depend on the vehicle's existing exhaust configuration.
▾ Is the advertised horsepower figure measured at the rear wheels?
No. The advertised 750 horsepower figure represents engine horsepower rather than rear-wheel horsepower.
▾ Is tuning included?
Yes. The package includes HP Tuners credits, custom ECU calibration, chassis dyno calibration, and street drivability calibration.
▾ Is baseline dyno testing included?
Yes. Baseline chassis dyno testing is included to document the vehicle's performance before installation and provide a reference for evaluating the completed package.
▾ Does this package include a warranty?
Yes. The Stage 2 package includes a 1-year / 12,000-mile Katech limited warranty. See Katech limited warranty terms and conditions for complete coverage details, limitations, and exclusions.
