The CMCV are these little flaps that restrict airflow in the intake runners to increase air velocity.
At low RPM, these flaps open and block off the majority of the airflow in the runner to increase air velocity. This improves response, increases low RPM torque, and flattens out the overall torque curve of the engine. Since the Gen-1 cannot control them, we are going to disable them.
To disable the CMCV, we needed to remove the vacuum powered actuator from the manifold.
All that’s left to do is to zip tie the CMCV arms down to keep the flaps open. That’s it!
Back on the car, we had to remove the stock intake manifold.
With the help of our Mustang-specialist friends at RareFab in Boynton Beach, FL -we removed the stock intake manifold.
