These tests are conducted daily in Isky's new enlarged dyno facility to properly evaluate and prove the efficiency of Isky racing cams and valve train components. Still another dynamometer is used exclusively for the purpose of testing the endurance of racing valve gear components in today's OHV engines. The final phase of testing is accomplished when the newly dyno tested cams and components are coordinated with the best stock and performance equipment into racing cars and boats as well as performance and stock street machines. The testing is completed under actual racing and street conditions that our customers may encounter. This assures the consumer of accuracy and quality control unparalleled in the industry.
