Charge Motion Delete Plates - revisited
I was thinking about doing this mod and called a reputable speed shop and asked their opinion. BTW they sell Steeda economy plates.
I was told that since I am N/A they don't recommend the plates unless I have 3:73 or lower gears. The plates don't really benefit you until you are around 4000 rpms and above. He also said that you actually lose alittle low end torque and it is noticable driving around at half throttle.
I am not disputing what the guy had to say, I was just wondering if anyone wanted to jump in here with comments. Remember 3:55 gears and N/A please~

ok I take that back. when (IF) you go buy the plates, make sure you get the steeda billet plates for $350....they really are way better.
We have the Steeda plates for $299.95 - http://www.stillen.com/product.asp?i...&model=MUSTANG
Free shipping ($9.95 I&H Fee).

i made the huge mistake of making my own....it is too bad they work so well. I just wish i would have spent more cash 

BTW thanks for the writeup Bill! you should compile all of those into a book and sell it. I would buy it not only for the great instructions but on principle alone!

Dave,
I just ordered breathers and some vac caps. I am going to delete the PCV system all together. I had the Moroso catch can and couldn't find a spot to put it in my engine bay.
Another thing that's great about this mod, especially on a boosted motor, is that it keeps the octane constant. Oil (blowby) induced into the engine decreases octane which could lead to detonation.

Just a thought. I've got a convenient place to mount my separator, so I'm just going to stick with that. With your centri, though, I could see how you might run out of real estate.

Gotta pull the can, change some fitting angles, and polish it up, but I'm happy for now.
I installed a set a couple of weeks ago and didn't notice any loss in low end torque or HP. I lost about .5 GPM (I think) The reason I finally installed them is that EVERY dyno sheet I saw posted online showed HP and TQ increase through out the RPM range.
I'm not sure if you are being sarcastic or not but if you did your own plates and are happy GREAT! Why would I even consider the $350 billet plates when economy plates would be fine for my application?
I have decided that I don't want to lose the ability to just take off the CIA, install the stock air box and reflash to OEM tune. Sooooooo I won't be doing this mod. Thanks for all the replies everyone.
Are you planning on some sort of evacuation system, even just draft tubes dropped under the car? With just breathers, you may wind up with more crankcase pressure which will cost a couple of ponies... If you're going "old school," take a look at the breather setups on some older drag cars, where they tied a siphon tube into the exhaust headers to create negative pressure in the crankcase. I'm pretty sure the idea was reducing windage-related losses. I've also seen siphon tubes dropped under the car (secured to a frame rail) to allow the airflow under the car to suck out the badness. Push-on breather with a hose nipple on it is what they used.

That is a nice simple system, and a good looking one to boot...
All I'm talking about is substituting this:

for the vented breathers. The "syringe" part of the kit is actually a check valve, and is designed to be welded into the collectors, using the exhaust flow to generate the venturi effect that creates crankcase vacuum. OR, you could just use the breathers and drop a tube down to the frame rail. The airflow under the car blowing across the tube will create some vacuum in the crankcase. By no means "telling you what to do," just offering some food for thought, or other ideas to consider. The kit runs $40 at Jeg's, and the breathers are $8 each at Summit, just to put a ballpark price on things...

good luck with whatever you end up doing.
I think I know what speed shop you're talking about, too. They always try and sell people on the gears at the same time.
However, that's bullcrap. You could have a stock air box, pull out the butterflies, and find tons of top end horses. PM me if you're interested in a super deal on some.
