Our Dynojet 424 with Linx System is a state of the art tool used to measure the horsepower and torque of your car. This machine also gives us the ability to tune your vehicle safely and accurately. The Dynojet 424 Linx System is a simple, highly efficient design that incorporates a high-speed Multi-V Rib Belt and pulleys that eliminate potential speed differentials between the dyno drums. This technology allows us to test modern AWD vehicles without the fear of potentially damaging the center differentials or activating intrusive stability control systems. It is also useful for those 2wd performance vehicles that require all four wheels to be rotating in order to avoid “reduced power mode.” Our Dynojet is also equipped with an Eddy Current Load Cell that we can use to simulate road conditions and add load to your car for building boost and tuning of hard to get to load cells.
