What is this CMDP or CMCV Delete i keep hearing about... i have managed to learn a little bit that the cmdp helps the throttlebody out but need more knowledge on it... please explain and how hard are they to install..?

Thank's

Ok the the stock cmcv's are garbage and don't do what they are supposed to. They are like a second throttle body that sucks and hurts power.

Now....if you delete them you will gain power and engine efficiency. I would recommend the steeda race plates. They deliver more power and have a better port match. Also your car will rev easier and your intake will sound more beast mode..

Install is simple but time consuming 2-3hours, 1-1.5 if you are good. There are 10 bolts that need to be removed. 2 are on the inside bank of the intake manifold. They are located between the 2-3 intake runners on each side. You will see them after you take out the fuel rails/injectors. Also you will have to disconnect the control module and take all the 3 bolts out of that. Then you have to take the 4 or 6(can't remember) torx head screws out of the plates that go into the manifold. Then take the 8 green gaskets out put them in the new ones and then slap it back together and tune it up.

Then enjoy your mid range to top end power! Hope this helps.

At the end of each intake runner there is a plate with butterflies that regulates the airflow into the cylinder head thus claiming to increase fuel mileage and low end torque. All the the CMCV (Charge Motion Control Valve) deletes are, are OEM castings (Steeda Economy plates) without the butterflies and butterfly shafts therefore creating less restriction in the intake path resulting in around +-10HP up top in the RPM range, and with a good tune will show very little to no low end torque loss.

Basically to break that down even more, Ford tried to improve gas mileage by putting butterfly valves below the plenum.

The CMVC's are just a plate that replaces the one holding the butterflys.

Hope that helps a little more, navy summed most of it up.

I didn't lose any torque and I got some more topend. And if you are planning on cams and you are not getting a twinscrew supercharger, then these are a must.

I have cams and I don't have them yet. Not that I don't want them its just I'm not sure if my car is gonna pass emissions testing here in Ontario the way it is now. I have never had to get a car e-tested before so I have not idea how strict they are here.

Find out if they just plug it in or use a sniffer.

Did some research and yes, they do use a sniffer. I just can't find the specs as to what is the max # of CO2, HC, etc... that is allowed before it fails. I'm also not sure if I can pass with Dougs race tune. I will probably get in touch with him a couple months before the test to get an emissions tune.

navyman8903 · August 27th, 2009, 10:23 AM

I would call a mustang shop in NY they will help you pass emissions........however possible.

ia07gt · August 27th, 2009, 11:41 AM

has anyone ever dynoed the CMDP's on a supercharged car to see the increases of power, i prefer to see a centri dyno.

navyman8903 · August 27th, 2009, 12:04 PM

That would be hard(I'm not shitting on you) seeing as how they are usually a mod you do 1st, then the SC but there might be someone......

ia07gt · August 27th, 2009, 12:12 PM

i know im allready supercharged but i have 3 more mods really left to do before breaking into my engine.
Longtubes
CMDP
Throttle body

Don't forget that he needs to make sure the gaskets aren't damaged before he swaps them into the new plates.

you can dyno and see the benifits then.....You are getting the steeda race plates correct?

NastyFX4 · August 27th, 2009, 01:20 PM

Only time I'd recommend getting the billet race plates is if you're going all out. Also, the economy plates are going to be stopped being sold very soon. So if you want those, I'd order them ASAP. The gains are small and you'll probably make ~6 rwhp and rwtq from them but every little thing adds up. Plus you won't end up like this guy ...

navyman8903 · August 27th, 2009, 01:24 PM

I'd get the steeda ones...They are the best and you don't have to worry about anything once they are in or regret anything.

NastyFX4 · August 27th, 2009, 01:25 PM

Steeda is the only company to make CMCVs as far as I know.

they are not the only company that makes them, just the only company you should go to.

DRock · August 27th, 2009, 02:02 PM

im pretty sure that you have an 09 Mustang so you should not listen to any of the guys telling you to get these................For the 09 Mustangs ford actually welded the CMCV's onto the intake manifold for some god unknown reason....... so unless you are getting an old intake manifold plus these or a aftermarket intake manifold you cant have them.........and dont even think about the plugs steeda sells there is major horror stories over those......
