Making functional hood scoop.

[explict]

So here is how I did it:
I did this last year so there are some minor details I can't recall.


First: remove hood scoop. A couple nuts and a few clips.

Then remove the front piece off of the scoop itself (this required a heat gun to get the glue apart):

http://i51.photobucket.com/albums/f381/explicit69/DSC_0107.jpg

Then make cuts in the front of the hoodscoop so that you can still get side pieces in to the holes:

http://i51.photobucket.com/albums/f381/explicit69/DSC_0108.jpg

I then put a large piece of cardboard under the hood so as to not get aluminum shavings everywhere:

http://i51.photobucket.com/albums/f381/explicit69/DSC_0113.jpg

I then made a very large outline of where to cut, following the curves of the holes:

http://i51.photobucket.com/albums/f381/explicit69/DSC_0116.jpg

After cutting the front piece of the hood scoop to match the hood scoop cutout I then placed the pieces back onto the scoop.

Then I cut. Yup I loved it.

This is the aluminum shavings. You can also notice the notch in the hood from when my blower belt failed!

This is what it looked like before putting the hood scoop back on!

Here is putting it back on, lining up the bolts.

And this is what it looked like with the scoop back on.

This has survived 240+km/h and many many road trips. It still uses all the factory bolt holes so it is strong.

So how has it held up, do you get much dirt and rain/snow coming in, and can you tell any difference in the underhood temps?

[explict]

There was no extra dirt in the engine bay, but I do clean it every now and then regardless.

If I never boosted, I could put my hand on the blower after a long drive. I don't know what it was like before but I know my blower stays nice and cold!

[miketexass788]

I also make my hood scoop functional, but I dont have a pretty blower to show off under!

Man this is tempting to do!

I did mine this weekend after seeing this post last week. Only thing I did different was I removed all the Honeycomb grill insert. I love it. I did some prelim. data loging and my IAT was ambient temp. I'm going to do some back to back testing when I get to feeling better. tape the scoop and read the IAT then un tape the scoop and read the IAT. I'll post up and let you know how it works out

[Lightblade]

nice job im thinking about doing this and putting a billet grill over where the honeycomb normaly would be and of course paint it black to match my grill

[circusboy]

since it was halloween I re-installed the cobra-r hood and steeda race wing this weekend. I didn't get the data loging done, sorry. I did data log the cobra-r hood. 48 deg ambient temp 50 deg IAT at 60 MPH. I'd say it works. I will get some pictures of the stock hood up tonight.

I have my stock hood in the shed man , I can pull off the scoop when I get back in and check for ya .....just remind me I have a shitty memory ( FWIW I do know it will cover the shaker cutout front to back wise though not sure on the side to side )

I remember when they tried that on a 2001....after awhile the wind ripped it off into the windshield. Use caution as it wasnt designed for that.

[waketek516]

I did this several years ago to my B9 scoop. Its MUCH larger than the stock one, and i cut a much larger hole.

I didn't take the scoop off to do it, but this is what it looks like:
http://www.waketek516.com/images/February-2010/DSC05291.jpg

[Lightblade]

I know you didnt take it off i just cant see what it looks like good with the doctored pic.
That works see now i can see there is a grill in the scoop which i couldnt see on the old pic so hows it workingout, anywater getting in? does it help anything?

[06z28eater]

i picked up a boss 429 scoop, i may try this with that. i just worry about water getting down in there.

[waketek516]

I honestly haven't noticed that much water in there at all. I think the grille on the scoop prevents alot of it from flowing up the hood since there's 3M holding down the bottom of the scoop-grille to the hood. Although after driving for a little bit, I can see the heat radiating out of the scoop. I haven't taken actual before & after temp readings, but visually you can see A LOT of heat escaping.

Maybe I'll tape it off this weekend and try to get some readings if I can.

[Lightblade]

Yeah i can see it letting heat out at a stop for sure, im wondering more about driver as its gonna force air in and the hot air is just goping to escape mostly out the bottome of the car but the cooler air coming in the scoop should still help with temps i would think.

I would need to fnd a black billet grill to fit the oem hood scoop.

[HOLYWD]

im going to do this next saturday with my ROUSH scoop

[Mister Roper]

How I did mine... It's survived some pretty heavy rains with no issues other than a little extra housekeeping.

I made my stock hood scoop functional a couple years ago. I removed the entire front faux grill from the scoop and made my own grill from aluminized material so it won't rust. I didn't cut out as much of the hood, but it still keeps the engine a bit cooler....

[06GTMustang89]

definitely doing this, this weekend!! I have the roush scoop....all i know is i got my matco tools qikscan and i can get live data streaming...the IAT is ridiculous so ill do a test where i tape it and a test with it open on the same day and same speed to give a difference...

didn't have a chance to tape it off...but i did run live mod on my scan tool and at 55mph the IAT was 68 degrees...ambient air was 63 degrees so only 5 degrees warmer than the outside air!! Good free mod guys...

Also worth noting, I shimmed the back of my hood up with a couple flat washers on each hood hinge bolt to let the underhood air out at the base of the windshield. Coupled with the functional hood scoop, it really keeps underhood temps down.

[06GTMustang89]

good call...i will do this very soon..do you remember how much you shimmed?

Do you have additional pics? This is something Ive planned to do since I got the car. But, when you cut out all of the fake grille area, you sacrifice three mounting studs. I see you still have them in use. So, how did you get to reuse those with the aluminum screen?

[Lightblade]

Used a dremel for the dirty work, was a pia to get the honey comb off the scoop damn strong-ass silicone tape.
I cut out the middle mounting point on the scoop and plastic stud off the honey comb and left the outside 2 to remount it.

Now i just gota cut a hole in the hood and slap this sucker back on! lol

[HOLYWD]

looks great man , doing mine hopefully this weekend after my scoop is painted

[Lightblade]

Thanks, its really not as bad or hard as i thought it would be, im excited about this mod, now i can say i have a functional hood scoop lol. It took me all all of 5 minutes to unbolt and release the locking clips to pull the scoop off. Took about an hour to dremel it just kinda winged it, came out pretty good. Not sure how much of the hood i wanna cut out yet underneath. Im also kicking around the idea of putting a single heat extractor vent on the top of the scoop towards the rear to help let heat out as well.

[Greg Hazlett]

More to follow on this one..still can't believe we cut a hole in your hood!

[martinr69]

Looks good I may have to do this if I don't go with a cowl hood..

[Lightblade]

So here is the hood cutting process all done. Greg and I went to town on it with a pneumatic cutting wheel, power grinder and sawsall. Cutting wheel wasnt doing the job too well so the sawsall picked up the slack.

awesome , they will be done painting my scoop monday

[BubbaRATM]

this is a project i am interested in but i dont have a factory scoop and there is a 6 cyl running around here in town with a scoop, maybe he will trade me hoods and i can do it that way. I know i can buy a scoop but i dont like how any of them look except the factory scoop. This is definatly on the list to do. HOLYWD , post up pics when you get it all done, i want to see it on your silver car.

[HOLYWD]

havnt cut it yet , will do that monday

but got the scoop painted & installed !

[Lightblade]

I didnt do this for a homemade ram air, or to lower iat as its not gonna really do anything in that respect. It lets some cool air in while driving and gives a place for the enigne bay heat to escape to help lower underhood temps.

That's pretty nice! I have the B9 and was wondering about doing this. Was it hard fabricating the custom grille?

[Lightblade]

I followed everyones lead and did the hose trim as well.
Turns out i had just enough hose left over from the coolant res and power steering res relocation to fit up. I used the smaller 3/8" hose for the sides and foward piece, and i used the larger 1" hose for the back. The back piece i didnt slit all the way through i just notched it most of the way to cover the edge of the hood and that way its wedged in there to block off the dead space in the back of the scoop and direct it down towards the engine bay better.

[SilentScope]

i would do this except my hood scoop is riveted into the hood, which is quite annoying.

[NastyStang113]

i would do this except my hood scoop is riveted into the hood, which is quite annoying.

I'd like to do this too. I'm just trying to find a "U" gasket that would work better than just using a split hose. I think I'm going to just drill out the center section of the honey comb and cut a smaller section of the hood out. It's got to be better than nothing. Also, it looks like the two pieces of the hood are pretty damn close at sections. Are the pieces close together at the front? In the pictures it looks like it is for sure in the back. Anyone know what the thickness is at these sections? .. or even the thickness of one layer of the hood?

[Lightblade]

The split hose actually works really well and looks a lot better than i thought it would. It also helps keep water from getting in when you spray the hood down when washing. Each layer is about 1/16" thick and yes it single towards the front and doubled up with a groove towards the rear where the hood undersupport framing is.

I noticed there was a dead spot in the back of the scoop ie the scoop directs air down but the hole in the hood doesnt go back that far. Thats why i used a thicker piec of hose there to block this area off. I also raised the rear of the scoop slighty to let air out for the heat extraction effect when driving.

Im currently kicking around the idea of putting a heat extractor louver on top of the hood scoop but not sure how to go about it or how it would look.

[NastyStang113]

To each his own I guess. It just doesn't look finished to me. I think I'm going to create a hole about half of the size towards the front of the scoop so that I can cut out where the two layers of the hood are close. Than I'll finish it with the U Channel.

[Lightblade]

I thought about just cutting then one layer area towards the fron of the scoop, but im glad i didnt, the large cut lets heat out alot better.
Your gonna want to cut it out towards the rear of the scoop as the air hits the underside of the scoop and gets directed all down at the rear. Luckily i did mine when the pollen was just starting to come out, the pollen showed me exactly where the air was coming in and hitting and it was all on the back of the intake manifold and firewall, basicly the bac/ last 2-3 inches of the hole i cut.

[NastyStang113]

We'll see, something is better than nothing.

[Lightblade]

If your gonna do it, do it, dont fear the hood, just cut it! Lol

[explict]

Yup, you can always buy another one!!

[NastyStang113]

Yup, you can always buy another one!!

Exactly. Maybe if I make it too big I'll just buy a new car.

[mac10chap]

i was worried about it too...glad i did it now. and i used a skil saw with a metal blade. try being careful of not scratching the rest of the hood with a 20lb skil saw hovering over your hood.

[Lightblade]

Exactly. Maybe if I make it too big I'll just buy a new car.

LOL

[NastyStang113]

Thought about what you said. At worst I can block off the rear of the hood scoop so that air is forced to go directly into the hole. Although I still don't see it being a problem. The air would go to the back of the scoop and than "try" to go back out but it'd only get stopped by incoming air. Only so much air would be caught in the rear of the scoop and anything else would go into the hole in the hood.

[Lightblade]

It forces its way between the scoop and the back of the hood as welml i could see it lifting in the rear on the highway. But thats not really a bad thing, at least it has a way out so you dont have to worry about the scoop ripping off lol

[NastyStang113]

Thank god for it being bolted!! :D

[Lightblade]

Thank god for it being bolted!! :D

Yeap!, btw be careful not to break any of the locking tabs as thats the only thing that holds the rear of the scoop down. There are 4 bolts 2 in the front and 2 on the sides about halfway back, no bolts on the rear, but the clips do a good job of holding it on.

[NastyStang113]

I pulled it off last night to mess around with it and make sure there was no 3M tape holding it down. I didn't realize those two rear clips until it was being held on but I quickly saw them and got it off. It's defiantly a lot easier with a second set of hands to hold the scoop up so the other clips don't go back in! I experimented with cutting the grille out in the scoop, without taking it off, not perfect enough for me so I'm going to end up making my own grille for it. I'm going to try to put the hood liner back on and see if I can get it to fit otherwise I'm going to have to sweet talk my painter in doing me a favor! LOL

[Lightblade]

Yeah those back 2 clips got me at first too. Had the same problem i would pop one out and the other would go back in lol. I originaly wanted to do a billet or mesh grill but once i looked at the scoop and stock honeycomb insert i decided to keep it and just cut the back off. I like how it turned out, you really have to look close to see its cut, especialy with the hood closed.

[predator]

I have also thought about doing this... I dont drive my car if I know it will rain, but you never know when you will get stuck out in it. And I have a polished Kenne Bell. I dont have to tell you what will happen if water hits that hot polished aluminum. So just a matter of either figuring out a way to keep water out or find a way to temp. close it off if I got stuck out in the rain. Maybe if I were to just cut out a portion of the rear of the scoop and an opening in the hood and use it as a heat extractor.

Was also wondering if any of you with the twin screw blowers noticed if it got any louder with a hole cut in the metal hood?

[bcb06gt]

Going from a Saleen supercharger to the Saleen Supershaker I noticed an increase in blower noise.

I can imagine that it would. The only thing blocking sound coming from inside blower is the filter.

I'm dying to make my KB 2.6 louder. Anyone else curious about this? Ill be spinning it faster anyway, but. Dont care if I have to pour sand in the gearbox of it. Figuratively speaking of course. I'd like to keep it in one piece.

[kahmann]

I also did this mod, but with my Shelby GT hood scoop. The original was warped badly, so I got it replaced under warranty. The new scoop is made of fiberglass instead of what appeared like Tupperware. The SGT scoop is a little different than the stock Mustang scoop and required a lot of shaving from the inside of the scoop itself. Otherwise, it was a much needed mod. I was tired of having to say 'yeah, the scoop is fake'.

The SGT scoop is a little different than the stock Mustang scoop and required a lot of shaving from the inside of the scoop itself. Otherwise, it was a much needed mod. I was tired of having to say 'yeah, the scoop is fake'.

ok i had the same issue, had it replaced. they said the rivets on the scoop are real. is this true? i havent taken my hood blanket off to see?
i want to do this too... how hard was it?

^The rivets on my 08 were real. I replaced them with button head, allen screws and lock washers, which look a lot better in my opinion.
I know that most of the 07 scoops were held down with 4 bolts, but if yours was a later build, the rivets may be real. The blanket is easy to pull off, if you felt like checking it out.
As for how easy or hard, it just depends on your experience with stuff like this. If you're unsure at all, take it to a trusted body shop. The labor bill ought to only be a couple hundred bucks and well worth not screwing your hood up.
I also had my hood stripes painted on at the same time, which was another mod I'd highly recommend. The Shelby stripes are crap and will get spotty and/or faded in no time. Good luck.

When I put my CDC shaker kit on, my wife got home from work just after I had cut the hole in the hood. She was nearly screaming when she said "I didn't know you were going to cut a big hole in the hood. Since the pipe coming from the shaker is 3" dia at best, I removed all the tubing coming out of the scoop and then did what Don W did. I cut the bottom out of the scoop so I got a flow thru design to help cool engine bay

Used a dremel for the dirty work, was a pia to get the honey comb off the scoop damn strong-ass silicone tape.
I cut out the middle mounting point on the scoop and plastic stud off the honey comb and left the outside 2 to remount it.

Now i just gota cut a hole in the hood and slap this sucker back on! lol

How DID you get it off? Heat it up? Fishing line?

[Lightblade]

Heat gun and elbow grease, killed my fingers prying it off though

[FalconGTHO]

K, thats what I figured, I previously purchased a heat gun just for this.

You may not want to cut the corners so square. If you put enough round into them it would be a lot easier to put trim of some sort on it later. May also look better and help keep water seepage out.
