It features a patented self-lubricating design with a 4-ounce oil capacity, eliminating the need for external oil lines. The unit is constructed with a 7075 billet aluminum impeller and a CNC-machined transmission case to provide rigidity and thermal stability under high-boost conditions.\n\nKey technical specifications include a 1,700 cfm maximum airflow rating, a maximum boost pressure of 38 psi, and a maximum impeller RPM of 68,000. The supercharger utilizes a 4-inch inlet and a 3-inch outlet.
