The Art and Science of Power Tuning

At the forefront of Roost Dirt Sports, powered by Hypertech, is our advanced R&D center in Memphis. Here, our team of engineers and technicians employs two computerized chassis dynamometers to develop the most potent tuning programs tailored for Polaris RZRs. Our process begins with experimental adjustments of spark timing to achieve optimal torque and power readings at specific engine RPMs. Simultaneously, we finely tune the air/fuel ratio to unleash maximum power and torque potential with an optimized mixture. This meticulous optimization is carried out point by point, gradually increasing the RPMs to the engine's peak. This precision-driven technique, known as experimental point-by-point curve fitting, ensures unparalleled power tuning for Polaris RZRs.

To guarantee exceptional performance, our Hypertech Power Tuning calibrations are extensively tested under real-world driving conditions. These tests validate the impressive power gains you can feel and the unwavering dependability you can trust. Roost Dirt Sports, powered by Hypertech, offers a paradigm-shifting approach to optimize the performance of your Polaris RZR.
