hey guys im new to the s197 scene and i have been hearing about charge motion control valves. what are these things? what do they do? and why do people delete them? thanks.
FORD RACING charge motion control valve (CMCV) assemblies
4.6/5.4L SOHC 3-Valve
Remove the restriction of CMCV blades and shafts by installing a set of Ford Racing charge motion control valve (CMCV) assemblies. Reduce turbulence and improve airflow in the intake. Ford Racing CMCV DELETE plates require computer recalibration for use which is available and installed on all DiabloSport predator tuners. Once tuned Ford Racing CMCV DELETE plates (charge motion plates) you will not have sacrifice any low end torque and provide midrange and upper rpm horsepower and torque increases. Peak increases of up to 10 horsepower on naturally aspirated applications, even more on supercharged applications!
Installation of this kit is quite simple and should take no more than 2 hours to complete.
EDIT: If I remember correctly, on the 2007+ Mustangs the Control Motion Plates are molded into the intake and can NOT be replaced, but, if you have a 05 or an 06 you can change them out.
The integrated plates are on the 09 and 10. The 05-08 can be replaced with the units that are pictured above. You replace them to increase airflow, if you plan on getting a roots type supercharger then its not required to buy them. If you're going to stay N/A or go with a turbo or centrifugal style SC then get them.
