Choosing Performance Camshaft Valvetrain Dyno
|
Camshaft manufacturers spend plenty on R&D of different grinds. They use a "spin fixture" (enclosed behind the blue wall in case of errant parts at high rpm), which rotates the engine assembly and monitors valvetrain actuation stability and durability. It's a valvetrain dyno. Ten years ago, these installations were so costly that only a few manufacturers had them. Now, they are in most top flight engine shops. View Related Article
