BHJ supplies technology-based products and services for torsional control to the high performance industry worldwide.
Our mission is to ensure consistent, dependable technical analysis, coupled with modern CNC manufacturing practices, to produce cost-effective solutions that consistently exceed our customers' requirements and expectations.
BHJ's Custom Design Service is directed toward discriminating engine builders, engine development programs and restoration connoisseurs who understand the extreme value of torsional control.
BHJ's design service produces harmonic dampers with better functionality and/or enhanced performance, for higher performance applications.
BHJ's three-level approach guides the engine builder to the exact tier of design involvement to accomplish their goals based on the engine's parameters and include:
- Mathematical Torsional System Modeling:
Mathematical models of internal combustion engines and attached driveline systems are created and used to calculate and predict the torsional characteristics of the systems.

On-site dyno testing of the operating engine. Involves actual measurement of the torsion levels in the crank on an engine dyno, or chassis dyno. All rotating group parameters, real-time temperature and driveline effects added to the crank are recorded.

Accessories, such as isolation pulleys, drive mandrels, ignition trigger wheels and other components are commonly required as part of damper projects.
Design and manufacturing services are also available for components such as these, either as part of a damper project, or separately.
