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 Magnuson 2650 supercharger, Halltech STRX 2650 intake, Katech CNC-ported throttle body, billet low-profile valve covers, PCV adapter fittings, upgraded thermostat, and required supporting components are installed as part of the complete Stage 1 Supercharged package.
Supercharger and Induction Installation
The Magnuson 2650 supercharger system is installed with the Halltech STRX 2650 intake, Halltech coupler, and Katech CNC-ported LT1 throttle body. Supporting components, including the Katech billet valve covers, PCV adapter fittings, and dipstick bracket, are incorporated into the completed installation.
ECU Calibration
The package includes the required HP Tuners credits and custom ECU calibration appropriate for the Stage 1 Supercharged 625HP performance combination. Calibration is developed to support the Magnuson 2650 supercharger, upgraded induction components, 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 torque output and operating characteristics of the supercharged LT1 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 1 Supercharged 625HP package takes advantage of Katech's in-house engine development, professional installation, calibration, and validation capabilities to deliver a complete supercharged LT1 performance system.

Frequently Asked Questions
▾ Does this package include installation?
Yes! All listed parts are professionally installed by Katech Engineering as part of the Stage 1 Supercharged package.
▾ How much horsepower does the Stage 1 Supercharged package make?
The Stage 1 Supercharged package is rated at 625 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 2014-2019 Chevrolet Corvette C7 Stingray and 2017-2019 C7 Grand Sport models equipped with the GM LT1 6.2L V8 engine.
▾ What supercharger does this package use?
The Stage 1 Supercharged package features the Magnuson 2650 supercharger system combined with a Halltech STRX 2650 intake and Katech CNC-ported LT1 throttle body.
▾ Does this package require internal engine modifications?
No. The Stage 1 Supercharged package is designed around the factory LT1 camshaft, cylinder heads, and valvetrain. It focuses on adding a complete supercharger system, supporting bolt-on components, and professional ECU calibration.
▾ What is the difference between the naturally aspirated Stage 1 and Stage 1 Supercharged packages?
The naturally aspirated Stage 1 480HP package focuses on intake, throttle body, cooling, and calibration upgrades. The Stage 1 Supercharged 625HP package adds a Magnuson 2650 supercharger system and supporting components to deliver substantially greater horsepower and torque.
▾ What is the difference between Stage 1 Supercharged and Stage 4 Supercharged?
The Stage 1 Supercharged 625HP package retains the factory camshaft, cylinder heads, and valvetrain while adding the Magnuson 2650 supercharger system. The Stage 4 Supercharged 725HP package incorporates extensive additional upgrades, including Katech CNC-ported cylinder heads, the K-Force 3 supercharger camshaft, upgraded valvetrain, a 103mm throttle body and supercharger snout, and dedicated supercharger drive components.
▾ Why does this package use a Magnuson 2650 supercharger?
The Magnuson 2650 is a positive-displacement supercharger designed to provide substantial airflow and strong torque delivery across a broad operating range. Its design supports the increased performance demands of the Stage 1 Supercharged LT1 combination.
▾ Will my C7 Corvette sound different after installation?
Yes. The Magnuson 2650 supercharger and Halltech STRX 2650 intake may produce additional induction and supercharger sounds compared to the factory naturally aspirated LT1. Since the factory camshaft is retained, the engine's idle character 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 625 horsepower figure represents engine horsepower rather than rear-wheel horsepower.
▾ Is tuning included?
Yes. Required HP Tuners credits, custom ECU calibration, chassis dyno calibration, and street drivability calibration are included.
▾ 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 1 Supercharged 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.
