5.4L 3v - Removed Charge Motion Device?
Crew,
I understand that the base of my 5.4L 3v intake manifold that there exists a set of 8 plates that closes (blocks flow to speed the air) during low speed operation for emissions.
Anyone out there remove this from your intake manifold (I've been told that this is simply bolted to the bottom of the intake manifold)?
I'm thinking, who cares about low-speed emissions....bring on the high rpm power by getting this crap out of the intake tract.
Thoughts?
Risks?

The 4.6 Cobra guys did this with their intake manifold runner control valves sometimes. Ford Racing Products sells an eliminator kit that does away with the IMRC valves and actuators and stuff. I don't think you can do it with the 5.4 3V, at least not easily, since the charge motion system is integrated with the drive by wire system. And besides that, it's a truck. I want all the power down low I can get.

Charge-motion devices do indeed improve combustion efficiency at low engine speeds. For emissions purposes.
They do nothing at all for low-end torque and may affect high-end power by being restrictive.
I could not find the 'delete' kit on the attached website but am interested if someone can point me in the right direction....
Thanks.

I have an '05 Mustang GT to go with my '04 Lariat and have been hearing things about these CMPs. The 'stang guys are reporting top end gains but losing a bit of their low end. The gains appear to be negligible - a few HP at most. I'm not planning on this mod, but A PCM tune + CAI are definitely in my future.

here you go defector! they don't have them listed seperately but i am sure it is available seperately.
