i heard that the charge motion plates are a real good buy for my 06 does anyone have anything they can add. I was just wondering if i should get them.my car come factory witha 355 gear i plan on adding nitrous would it run just as good as it would with a 4.10? i do some traveling out of town i was wondering what gear would really help my car the best in a 1/4 mile i recently wen 13.5 at 104 in my stang at bristol with stock gears which gear would be more beneficial?

 

What's a "charge motion plate?"

The lower the gears the better the 1/4 mile time.. also lousier fuel economy & high revving if you do a lot of highway driving,, so it up to you to decide which is more important.. is your car auto or standard tranny?

 

A charge motion plate is a "delete" for the charge motion control valves (CMCV) on the 4.6L 3V engines. The CMCV is an emissions related thingy, athrottle-like set of butterflys that live between the intake manifold and the head, and block off 1/2 or so of the port at low revs and loads--the PCM opens them at higher revs and more aggressive throttle positions.[/align][/align]Like anything else placed in an intake tract they restrict airflow (even when open), and increase turbulence. The charge motion plate is essentially just a spacer with the same size and shape as the CMCV assembly, but no butterflys.[/align]

 

My car has a manual tranny.
