Unlike other blowers, ProCharger’s Coyote systems feature inlet-air tubes that are positioned facing the firewall, as opposed to pulling air in via a pocket in the front grille or front fender area. Cliff tells us fitment is one of the reasons for the switch. Due to the shape of the supercharger, the tube is moved so that belt alignment (with the crank pulley) is accurate. The other reason carries more technical weight. Front-mounting the system’s inlet air would require an elaborate system of tubing that would ultimately create severe inefficiency in the supercharger. “We’ve done tests measuring temps at the blower’s inlet and the restrictions (bends and such) leading up to the inlet on front-mount superchargers.
