Isky Cams is a leading manufacturer of racing, performance, and economy camshafts. They utilize a comprehensive dynamometer testing program to continuously enhance their camshaft and valvetrain designs, conducting daily tests in their expanded dyno facility. To validate the performance of their racing cams and valvetrain components, Isky employs an ongoing engine testing program. A separate dynamometer is dedicated to assessing the durability of racing valve gear components in modern OHV engines. The final testing stage involves integrating newly dyno-tested cams and components with optimal stock and performance equipment in racing cars, boats, and street performance machines.
