My plans are to mount the IC in front which leaves the Hood scoop empty. This gave me an idea. How about making the intake suck the air from under the hood scoop and seal it so it only takes fresh air.

Has anyone ever done this before and possibly have written a write-up? That would take a little time off the install. Are there any drawbacks from doing this at all that i should consider before doing this?



There already is a cone filter on the intake replacing the stock filter which takes in the hot engine air so this seems like a logical improvment.

air exits the hood scoop

Really? Where does it come from. Wow, that's wierd.

it comes in under and in front of the car

well if you did

something to consider is getting a bypass valve for water or rain...

but since air exits the scoop then i dunno unless you mount really far up not just under the scoop coming right by your engine.

Me and my friends were thinking of somethion like that for my car but it was kinda hard and never heard of soemthing like that...

a commercial size freezer inside the engine bay, just put the intake right in that sucker...VRRROOM. Ok, so maybe that isnt the brightest idea, but it would be cool? EH? EH?

if it exits the hood scoop, why isn't the scoop facing the other way? that does not seem logical, i understand that there is a negative pressure differential on top of the hood, but by putting the hood scoop facing the incoming air flow, it just seems like you would add interference and impede the air flow. also, by drawing air in through the engine, it also seems like you will be sucking hot air through the intercooler, rather than cool fresh air.



i'm doubting yall's assesment of this cooling system.

OK this might sound really stupid or really smart... but i'm thinking this would be the ultimate "Cold Air Intake" if it worked





running A/C lines inside the intake as coils?? or would it be better to have them in the intercooler??



dunno just thought it up once........ https://www.nopistons.com/forums/pub...IR#>/dunno.gif



any opinions????

I would have to agree. It would be quite impossible for air to exit the hood scoop while the car is in motion. Does anyone remember the "Ram Air" cars of the '70's?



Look at it this way, Mazda put the intercooler under the scoop for airflow. The cooler the air through the IC, the more horsepower you will make. For the (HOT) air to come up from the motor, then go through the IC and out the hood scoop would be counterproductive, if it was possible at all. BTW - I think the placement of the stock IC is stupid, why put the IC on top of a hot motor???



Even if you could move your intake to the hood scope, it's really not a good option. It would be better for you to pipe it down into your front grill. I've seen someone who has posted a "How To" on thier web site, but I can't find it right now. I'll post it when I do.

well, if anything........ a scoop...... scoops air in, no point in having it face front if it doesnt scoop air.....



so i think if you make the proper ducts that would be a good idea........ but doesnt FC's have a duct coming from the front bumper already for the intake?

you could always go and get a right side headlight cover that has the air duct made into it..its like a 140 dollars..or you could do like me andmake one on your on

ok lets look at it from the other point of veiw. the turbo 1, was a 12a with about 4.5psi of boost and no intercooler. 12a turbo info. what they did to keep it from detonating, is dump extra fuel in and retard the timing in the "knock zone". when they added the intercooler on the turbo 2 it let them; a, raise the boost to 5.5, and it keeps it safer in the knock zone.

My dad used to work in a wind tunnel in germany when he was in college. He said that there is a slight vacuum on the top of the hood so he said a lot of the hood scoops are BS. There is pressure where the window where a cowl hood takes in air.



The hood scoop faces forward probably for looks and the pressure from the front of the car and the vacuum from the hood of the car make a nice flow. I just never thought of it working like that. Now I see why a front mount IC makes so much of a difference.

Here's the dudes site with the cold air intake mod.



Cold Air Intake







I wish the airflow pic was available to be seen on that post. Sounds interesting.

you do realise that those dont flow that much air? they are mostly for looks.

hard to get air to flow thru the header panel thats behind the headlights



A cowl induction hood would be ideal, I still say someone should make

a cold air intake that sits at the firewall so it can draw air from the windshield.

I was looking the the wind tunnel aerodyno for the FC and it showed the wind hitting the gril then bouncing up to where the hood scoop would be (It was an N/A), but supposedley they designed the car so that wind would hit the scoop when in motion.

Yeah it is you can remove the seal on the hood by the headlight to help out a little bit but it still wont be that good. Best not to waste the money unless you have nothing better to buy. Rob ill look into making your idea on the firewall mounted intake.

I think ford is doing this on the new lightning or something. One of there supercharged vehicles anyway.

I noticed that most of the people arguing that it would work are NA guys. When I had the stock IC, and went for a hard drive on a cool night, the IC would be almost too hot to touch. At lower speeds the scoop works ok, but it is quite usless at higher speeds. I think the scoop is more for looks, than function. Don't you think that if the scoop flowed massive amounts of air the FDs would have a hood scoop and the IC mounted where it is on the FC. https://www.nopistons.com/forums/pub...IR#>/blink.png

This is the reason why all radiators/oil/trans coolers are mounted front and center on nearly all autos. It just makes sense to install the intercooler there. Its all about cool air, that and the number of rows on specific cooling systems.

Mazda likes to place thier IC on top of the engine. The mx-6 had a top mount ic. the turbo charged 2.5l subaru has a top mount ic. But I would have to agree that front mount ic's are ideal and are more efficient.

well anyway you look at it, i think i'm gonna listen to mike.... https://www.nopistons.com/forums/pub...#>/biggrin.png

ditto

The reason why Manufactureersaaeeeeers use top mounted IC's the what i call the "******* driving unit" factor. A front mounted IC would not last long if you smash the front end going into a driveway, Enjoy tailgating trucks filled with gravel, or have VERY large bugs in your place or high speed driving. It also inhibits air from flowing past the rad slighty, which is not good. You have to remember that all cars are engineered for any ******* to drive, not just enthusiats to drive





sue me my grammar sux

I see. Never thought of it that way.
