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! :hehe: 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? :smiley_roll1: haha jk, i dont think that would do anything :p

You might make some actual HP's............j/k:smiley_roll1:

So in the spirit of gaseous fluid dynamical science, to find whether the ram air setup works or not we will....flip a coin. :hehe:

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. :nos:

Great idea! :smiley_roll1::hehe: but what if i get such a boost that i end up running him over?! :happy-dancing: haha

I was just thinking. :disbelief:
What if instead of a "Y" you put a 90˚? The engine will still be able to bring in air and if you did get going 200+ mph you would get a slight amount of boost.

If I were doing that project on a 5.4 I would cut the intake to allow the "Y" after the stock fender snorkel. That way the preferred source of airflow will be from the bumper instead of the fender. The fender would still be a source, just not as significant as the front. We also have to keep in mind that we can use a 6" inlet but the air is still having to squeeze through the rest of the intake, filter and throttle body. I remember that changes the properties of the fluid but I cant specifically remember how at the moment. :doh:
The gotts mod eliminates the largest source of airway restriction. Now you have to open up anything that has less than a 3 inch diameter...so I guess that would be the throttle body which I think is 75 mm to an 80mm. We're starting to get expensive now. :hehe:

But really this is all a mute point if you aren't either hauling buns down the highway or stuck in stop and go traffic all the time. :cheesy smile:

I guess I would steer clear of using anything else besides the fender hole.
Reasoning is mostly to where I live and the weather and debri. I know k+n can handle moisture but I don't think it would be to friendly to the stock panel paper filter. Adding the Y like you guy are doing might be a perfect water in let during rain or snow.
If the tubing intake could be dropped low enough where gravity would help keep the moisture out then that would be a plus.
I know 4.6 has the cylinder shaped filter.
The fender hole is the perfect spot to get away from all this.
Just some thoughts.
Peace!:)

I thought about the same stuff down here. Except I worry more about dust and dirt getting sucked in. My filter has to be cleaned every 6,000 miles as it it and the ram air would only increase the amount going in. But if you live in a cleaner area it would be good.

I'm really surprised this hasn't made it to the resource library?

Made a thread about it in the mods section but we were busy with CS/CTS stuff at the time so it got lost in the shuffle.

Im sure it would make us all feel special! :smiley_roll1:
