Our new bypass valve upgrade is a direct bolt-on to the Vortech V-3 HEMI supercharging system, (using existing sleeves, clamps and bypass signal hose), replacing the standard bypass valve. It's perfect for those owners seeking maximum horsepower through an increase in boost pressure. The Maxflow Bypass Valve improves supercharger operation by opening to relieve unwanted pressure during deceleration. Flow is rated at 320 CFM at 8 PSIG and the valve is preset to open at 4-5 inches of vacuum. The kit includes an aluminum discharge tube with welded bypass flange mount, Maxflow Race Bypass Valve with gasket and mounting hardware plus a bypass discharge filter. These upgrade kits are available in both satin finish (#4CL212-060) or polished finish (#4CL212-068).
