My own version!
So i looked at all the intakes that you guys have done, and kinda went my own way to do it. I didnt take any pics while installing it, but i did take a few after so let me know what you all think!
The first is the Y pipe with the 2 flexible hoses coming out.  This pic is of the duct work in front of the tranny cooler  This pic is what the intake looks like from the front. It is kinda hard to see with my cell phone camera, but that is all i had.  Well there it is, it didnt take too long to do, and so far it feel better and the Throttle Response is better at speed!

Looks good, ticopowell. I'm not sure that the "ram air" intake part is going to do much (Bill posted something on this fairly recently - talking about the Banks Ram intake), but, if the whole installation seems to be giving you positive results, I suspect it IS. I DO like that flex tubing. Seems a smoother airflow path to me.

Oh and I forgot that I got a K&N drop in filter in there too
 and yeah if the "ram air" does anything it will be at very high speeds, there is a lot of piping to go through and even if it does up the pressure by much the stock hole that it is still hooked up to will dissipate it... well at least those are my thoughts lol. I will have to go see what Bill said about a "real" ram air intake

 I wonder if they make a 3 inch one way flap type valve? (cant think of the technical term right now) If you put that on the stock intake location it would close up if there was a positive amount of pressure, but I dont think it would be worth trying. If you want to see if there is a difference put the MAF and IAT PIDs on the screen with the stock intake and then with the modified. Look at the readings under the same RPM and LOAD(So the 4 you pick would be IAT, MAF, RPM and LOAD). You would judge improved IATs by degrees from actual temp but the other 3 should be pretty straitforward. The reason I say both RPM and LOAD is because at 2000 rpm you can have 20 grams/sec of air with minimal load but 70 g/s with increased load. Cruise control will probably be the easiest if you dont want to take a series of datalogs and then stitch them together (not too hard to do though but if your interested but unable you can send them to me). ...hmm maybe I should see the effects of air intake restriction on my intake since there really isn't any info on the 4.6s.

Yeah that "might" be worth looking in to, but i think im happy with the cold air from the front of the truck
 and yeah im too lazy and dont care enough to figure out the differences... my butt-dyno says that they are there so i wont complain  and i gotta get my gryphon sent in to be updated to my new truck before i do anything!

OK, let's look at the "bold faced" statement:. "if it does up the pressure by much the stock hole that it is still hooked up to will dissipate it.."
Remember, you DO always have constant airflow UP the intake into the engine upstream of the "Y". So, that air HAS to come from somewhere. The amount of air moving is a function of demand by the engine and the supply capacity. If the demand exceeds the supply, the pressure in the tube is reduced. But, having two inlets to the "Y" should effectively add to the supply capability, regardless of "pressure". So, my take on it would be that there would be little to no "restriction" effect. However, any positive pressure provided by the tube going to the "ram" intake is going to be split, and any airflow gain may actually be canceled by turbulent interactions. I honestly don't know what the effect will be. As I've said before, aerodynamics is a VERY complicated "science", and it's not really that well understood. Most of the "theory" is empirically derived. You would need a lab setup to test the possible gains of this configuration. - Jack

Yeah i got a B in aero here at the academy so i have a very basic understanding of airflow, and on top of that we barely scratched the surface (of air?) of aerodynamics and airflow properties, but with this little knowledge i dont think the stock hole will add any resistance, I just think it will keep the air from the ram air intake to build any pressure, so it is just clean air coming into the engine versus pressurized air that would enter if it were a turbo or supercharger or something like that. but hey with a valve or a direct ram air intake it might build a whole .1 psi greater than ambient air pressure!
but hey, i feel good about getting the clean colder air coming in, now my question is what will happen if im driving behind one of you smokers with rear exit exhausts and i get all that in my engine? haha jk, i dont think that would do anything :p

So in the spirit of gaseous fluid dynamical science, to find whether the ram air setup works or not we will....flip a coin.
I say if the buttometer shows improved readings for less than $50-$100 then it is good enough. Especially when many popular products expect you to pay hundreds for a few extra advertised ponies. I might go back and test mine since I have gotten better at getting data and putting it together into a more sensible form. Hey, if you see some little ricer with NOS, you can get up behind him and scoop it up.
