Ford Mustang Owners in California and Beyond Get Boost: Emissions Approval for Roush Supercharger Kit A significant development has been made for car enthusiasts in states with strict emissions standards, including California. Aftermarket parts, such as the highly sought-after Roush Mustang supercharger kit, have long been restricted due to a lack of Certification of Compliance (CARB E.O.) from the California Air Resources Board. However, the 2026 Roush Performance Ford Mustang supercharger kit has now received the necessary approval, paving the way for owners in these states to install the kit without fear of violating emissions regulations. The kit, developed in collaboration with Magnuson Superchargers, boasts an impressive 810 horsepower and 630 pound-feet of torque, making it a highly coveted upgrade for Mustang enthusiasts.
This is notable because without a CARB E.O., aftermarket parts like the Roush Mustang supercharger can't be legally installed on vehicles registered in states including California, as well as others that have adopted its emissions standards and also require an E.O. number for emissions-altering parts. That's no longer a concern for owners living in those states now that the 2026 Roush Performance Ford Mustang supercharger kit has indeed received E.O. approval. As was previously the case, the Roush supercharger kit boosts output all the way up to 810 horsepower and 630 pound-feet of torque. It was developed in conjunction with Magnuson Superchargers and features an inverted Eaton TVS R2650 supercharger with a front-inlet, front-drive design, churning out a peak of 13 pounds of boost at 7,500 rpm while utilizing the factory 80mm throttle bodies. submitted by /u/TylerFortier_Photo [link] [comments]
