The Katech Installation Process
Vehicle Inspection
Each vehicle is inspected before installation begins to identify any existing mechanical concerns that should be addressed before modifying the engine. This evaluation helps establish a foundation for the completed Stage 4 performance package.
Baseline Dyno Testing
Baseline chassis dyno testing is performed before modifications to document incoming vehicle performance and establish a reference point for evaluating the completed package.
Cylinder Head Preparation
The LT4 cylinder heads receive Katech CNC porting, a 5-angle competition valve job, valve job blending, and .010-inch deck machining. These modifications are designed to improve airflow through the cylinder heads and support the increased performance demands of the Magnuson 2650 supercharger and upgraded camshaft combination. GM Gen V LT4 head gaskets and ARP head bolts are included for engine reassembly.
Camshaft and Valvetrain Installation
The Katech K-Force 3 or 2650 Race camshaft is installed with PSI 1516 valve springs, Katech tool steel intake and exhaust retainers, steel valve spring locators, Katech-spec Johnson lifters, and Trend pushrods measured for proper fitment. These components are selected to support the increased valve lift and operating demands of the upgraded camshaft.
Timing System and VVT Delete Installation
The factory timing configuration is upgraded with the Katech C5R timing chain and VVT delete components, including the delete gear, stanchion, bolt, and billet front cover. The package also includes the Katech billet AFM delete cover to support the completed camshaft conversion.
Magnuson 2650 Supercharger Installation
The factory LT4 supercharger is replaced with the larger Magnuson 2650 supercharger system. The Halltech STRZ06 intake, Halltech 103mm coupler, and Katech billet 103mm throttle body support increased induction airflow, while the GripTec pulley, ATI damper and supercharger pulley, and Gates belt complete the upgraded drive system.
Valve Cover and Cooling System Installation
Katech billet valve covers, billet PCV fittings, and AN plugs are installed as part of the supporting engine modifications. The cooling system is upgraded with a Katech billet thermostat housing and 160-degree thermostat, with GM Dex-Cool coolant included for service.
ECU Calibration
The package includes HP Tuners credits and custom ECU calibration appropriate for the Stage 4 950HP performance combination. Calibration is developed to support the Magnuson 2650 supercharger, upgraded camshaft, ported cylinder heads, supercharger drive components, and overall engine operation.
Dyno Calibration and Validation
Following installation, the vehicle receives chassis dyno calibration and performance validation. Dyno testing is used to evaluate the completed package, refine calibration, and compare performance against the original baseline results.
Street Drivability Calibration
After dyno calibration, the vehicle receives street drivability calibration to refine throttle response, idle quality, part-throttle operation, and overall driving characteristics. Particular attention is given to the operating behavior of the upgraded camshaft and increased supercharger output.
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 4 950HP package takes advantage of Katech's in-house CNC machining, cylinder head development, engine assembly, professional installation, calibration, and validation capabilities to deliver a comprehensive high-performance LT4 combination.
Every Katech Installed Performance Package is built around professional installation, calibration, validation, and support from the Katech team.
