Professionally Installed and Dyno-Tested Performance for the GM LT1
The Katech C7 Corvette & Grand Sport Stage 2 500HP Installed Performance Package is a professionally engineered induction and calibration upgrade designed to deliver 500 horsepower from the naturally aspirated LT1 while maintaining refined street drivability. This comprehensive package combines a Halltech STR Stinger intake, Katech billet 103mm throttle body, MSD Gen V LT1 intake manifold, Katech 160-degree thermostat, Katech billet thermostat housing, supporting components, custom ECU calibration, chassis dyno calibration, and final road validation.
Building upon traditional bolt-on performance upgrades, the Stage 2 package focuses on improving airflow throughout the LT1 induction system. The combination of a high-flow cold air intake, larger 103mm throttle body, and MSD performance intake manifold is designed to support increased engine breathing and stronger high-RPM performance.
Unlike purchasing individual components separately, this installed package is completed at Katech Engineering as a complete performance system. Each vehicle is inspected, professionally modified, calibrated, dyno tested, and road tested before delivery.

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 STR Stinger intake, 103mm hump hose, Katech billet 103mm throttle body, MSD Gen V LT1 intake manifold, 160-degree thermostat, billet thermostat housing, and required supporting components are installed as part of the complete Stage 2 package.
ECU Calibration
The package includes the required HP Tuners credits and custom ECU calibration appropriate for the Stage 2 500HP performance combination. Calibration is optimized to support the increased airflow of the 103mm throttle body, MSD intake manifold, and upgraded induction system.
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.
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 500HP package takes advantage of Katech's in-house engine development, CNC machining, professional installation, calibration, and validation capabilities to deliver a complete naturally aspirated 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 2 package.
▾ How much horsepower does the Stage 2 package make?
The Stage 2 package is rated at 500 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 naturally aspirated GM LT1 6.2L V8 engine.
▾ Is this package naturally aspirated?
Yes. The Stage 2 package produces its increased performance without adding a supercharger or turbocharger.
▾ What is the difference between the Stage 1 and Stage 2 packages?
The Stage 1 480HP package includes a Halltech STR Stinger intake and Katech CNC-ported LT1 throttle body. The Stage 2 500HP package upgrades to a Katech billet 103mm throttle body and adds an MSD Gen V LT1 performance intake manifold to support increased induction airflow and higher horsepower output.
▾ What are the benefits of the MSD intake manifold?
The MSD Gen V LT1 intake manifold is designed to improve airflow and support increased engine performance, particularly at higher engine speeds. When combined with the Katech billet 103mm throttle body and Halltech STR Stinger intake, it provides a more comprehensive induction upgrade than the factory LT1 intake system.
▾ Does this package require internal engine modifications?
No. The Stage 2 package focuses on induction upgrades, cooling system components, and ECU calibration without requiring camshaft, cylinder head, or other internal engine modifications.
▾ Why does this package include a 160-degree thermostat?
The Katech 160-degree thermostat begins opening at a lower coolant temperature than the factory thermostat, providing an additional cooling system modification for the performance combination. Actual operating temperatures depend on ECU calibration, cooling system operation, and driving conditions.
▾ Will my C7 Corvette sound different after installation?
The Halltech STR Stinger intake may provide a more noticeable induction sound compared to the factory intake system. This package does not include exhaust system modifications, so exhaust volume and character will primarily depend on the vehicle's existing exhaust configuration. Contact Katech sales for additional exhaust options.
▾ Is the advertised horsepower figure measured at the rear wheels?
No. The advertised 500 horsepower figure represents engine horsepower rather than rear-wheel horsepower.
▾ Is tuning included?
Yes. The package includes required 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.
