Katech C6 ZR1 Corvette Stage 1 675HP Installed Performance Package
675 HP Supercharged LS9 Performance with GripTec 2.6-Inch Supercharger Pulley, 100mm Idler Pulley, Attack Blue Air Filter, and Professional Dyno Tuning!
Unleash More Performance from the Supercharged LS9
The Katech C6 ZR1 Corvette Stage 1 675HP Installed Performance Package is designed to enhance the performance of Chevrolet's legendary supercharged 6.2L LS9 V8. Combining an upgraded GripTec supercharger drive system, improved induction airflow, and professional engine calibration, this package delivers 675 horsepower while retaining the factory LS9 supercharger and internal engine configuration.
At the heart of the Stage 1 package is the GripTec 2.6-inch supercharger pulley and matching GripTec supercharger hub. The smaller pulley increases supercharger drive speed compared with the factory configuration, supporting increased boost pressure and additional horsepower. GripTec's specialized pulley surface is designed to improve belt traction and help minimize unwanted belt slip under load.
Supporting the upgraded supercharger drive system is a 100mm idler pulley. The larger idler pulley helps improve belt engagement and maintain more consistent belt contact with the supercharger pulley, an important consideration when increasing supercharger drive speed.
An Attack Blue air filter and retainer are included to improve induction airflow into the factory LS9 supercharger. These components complement the increased airflow requirements of the upgraded supercharger drive system without requiring replacement of the factory supercharger assembly.
A 160-degree thermostat is included as part of the cooling system modifications, along with GM Dex-Cool coolant. Following installation, Katech performs baseline chassis dyno testing, HP Tuners calibration, chassis dyno tuning, and street drivability calibration to optimize the completed combination.
The result is a professionally installed and calibrated supercharged LS9 performance package designed to deliver stronger acceleration, increased horsepower, and responsive performance without requiring internal engine modifications.
Stage 1 also includes a Katech serialized Stage 1 plaque and a Katech 1-year / 12,000-mile limited warranty, subject to applicable terms and conditions.

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 1 package.
GripTec Supercharger Pulley and Hub Installation
The factory supercharger drive configuration is upgraded with a GripTec 2.6-inch supercharger pulley and matching GripTec hub. The smaller pulley increases supercharger drive speed compared with the factory configuration, supporting increased boost pressure and additional engine performance.
GripTec's specialized pulley surface is designed to improve belt traction and help reduce unwanted belt slip, supporting more consistent supercharger drive performance under load.
100mm Idler Pulley Installation
A 100mm idler pulley is installed as part of the upgraded supercharger drive system. The idler pulley helps improve belt engagement with the smaller supercharger pulley and supports consistent belt contact during operation.
When combined with the GripTec supercharger pulley and hub, the upgraded idler pulley helps support the belt drive system under the increased demands of the Stage 1 configuration.
Attack Blue Air Filter Installation
The Attack Blue air filter and retainer are installed as part of the induction system upgrade. The filter supports improved airflow into the factory LS9 supercharger and complements the increased airflow requirements of the pulley upgrade.
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 to account for the increased supercharger drive speed, airflow changes, and operating characteristics of the Stage 1 configuration.
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 1 675HP package combines carefully selected supercharger drive and induction components with professional installation, chassis dyno tuning, and street calibration to deliver a balanced LS9 performance upgrade.
Rather than relying on extensive internal engine modifications, Stage 1 focuses on optimizing the existing supercharged LS9 configuration through increased supercharger drive speed, improved belt engagement, enhanced induction airflow, and professional calibration.
Recommended Upgrades
For owners interested in additional horsepower beyond the Stage 1 package, Katech offers further performance solutions for the supercharged LS9 Corvette platform. Contact a Katech Performance Specialist to discuss available exhaust upgrades, cooling improvements, fuel system modifications, and higher-performance package options.
Additional components and services are not included unless specifically listed in the package contents.
