Katech works with management of an existing or new race series to develop vehicle packages, series spec engines, conformance testing, engine control software, team training, track support, and overall process improvements.
On demand, Katech can then follow through with program management for the series, ensuring that inventory, testing, technicians, and other resources are in place to keep the series running smoothly.
Katech draws on its 40 years of racing to develop engines that meet exacting performance requirements and regulations. We maintain a full-service CNC laboratory and six test laboratories to modify existing engines to series spec, and to validate performance.
GM built its legendary Corvette Racing Program on the insight and technical innovation of Katech engine developers and builders. That same expertise continues to be sought today by race series throughout the world.
If you need an engine built, Katech has the master engine builders to meet your needs and surpass your expectations. Katech engines are assembled using a rigorous 48-step process that is documented and kept on file at Katech for the life of the engine.
To meet the most demanding performance requirements, Katech performance testing labs are available, as required, to provide valvetrain dynamics testing; cylinder head flow testing; dynamometer durability testing and track simulation; engine calibration (MEFI4); and much more.
The Katech engine build lab is further supported by a complete machine shop.

Katech track support ensures that everything for the team and/or the series is running properly – with services from problem solving to engine tuning to ideas for continuous improvement.
A key part of Katech track support is race data acquisition and analysis, and calibration support for several data acquisition systems:
- AIM Sports
- MEFI 4
- Magneti Marelli
- Bosch MS
In addition, the Katech WHISTLER is a proprietary electronic device that instantly determines the compression ratio of virtually any engine. Whistler is used by NASCAR and SCCA.
