    I have been casually following the saga of the ill-fitting hood scoops on the SGT, and the various fixes and retrofits that are now wrinkling the hood sheet metal.

    In reading the updates, I caught something that I never realized...

    Is the scoop on the SGT purely cosmetic, with no cut-out in the hood?

    ...or is it a functional scoop?

    Purely cosmetic - no functional value.

    Thanks, Robin ... that's a shame that a dress-up item is causing so much grief.

    Seems like a combo of mismatched curvature and different thermal characteristics that cause the warp. I wonder if a cutout in the sheetmetal to make it functional would help...get rid of that solid surface under the scoop.

    The hood is cosmetic yet it is a nice throwback to the cobras. I like the look of the hood but i have been hearing this same complaint at stangsunleashed since early in the 07 model year....i wonder if they changed anything for the 08 cars???....best way to fix the problem....get the functional hertz style hood installed from the factory...like on the terlingua cars!....and ya know, while your at it..might as well ad a paxton for good measure...;)
    Best Regards,
    Vern

    It is the "right" look...but, frankly, I'm surprised. A bolt-on hood scoop that doesn't "scoop" (to me) is just goofy.

    20-20 Hindsight...you're right...a hood with an integral scoop woulda been the correct way to do it.

    You're surprised, where have you been? :confused: Hood scoops have been 'goofy' for well over 30 years it didn't just start with the new SGT's. The only functional scoops on a mustang that I can think of since the '70's MACH1's were mid '80's SVO's and '03 & '04 MACH1's.

    My '08 SGT's riveted on, non-functional hood scoop is just fine and looks great....

    I've been around. :rolleyes:

    I think this is the first "cosmetic" hood scoop on any Shelby product that I can recall.

    A functional hood scoop on a modern car like the Shelby GT’s is cost prohibitive. Do you realize how much engineering would be needed to get the air from the center of hood out to the front corner of the engine compartment to make it useful? There are several aftermarket companies that have come-up with a similar style hood as the modern GT/CS with a molded plenum to get air from the scoop to the CAI. The additional cost of manufacturing would drive the already to high price on this car through the roof.

    Most functional hood scoops have been long gone on ALL American muscle cars since the mid ‘70’s, not just Shelby products. There has been a loooooooong gap in production in-between your vintage Shelby autos and this current generation, yes things have change.

    I agree....much has changed in the technology...and you want the air to get where it breathes.

    That's why I can't appreciate the tacky bolt-on for some kind of retro look.
    If the snout slots are open, it looks like the KR hood gets it right.

    Not bad-mouthing the SGT. As I stated, it is a shame that all the grief with the scoop/warp/wrinkle/bending is not from a go-fast part, but from a tack-on just for a retro look.

    Here are three examples of modern cars with functional hood scoops.

    2006 Subaru Forester
    2005 Subaru Outback
    2008 Subaru Impreza WRX

    Not exactly super high dollar cars.

    Dont really want to chime in but i seem to remember the Mach 1 having a functional shaker. Not trying to bad mouth the factory as i really like the sgt and i really like the way the scoop looks.

    FWIW, the scoop on a '67 is only functional as an air outlet. I learned this when I blew a water pump on my car years ago. I found that the coolant that was getting on my windshield was coming out the front of the scoop. Seems that at speed, that area of the hood is in a lower pressure area than the rest of the hood. The air that goes through the grille area has to go somewhere and takes the path of least resistance. Just so happens that that place is the front of the scoop. I don't know if the situation is improved with the louvered hood or not. It is possible that to be truly functional, the air cleaner would have to be sealed to the scoop area somehow. I've often wondered if that is why the design changed in '68. That one works. The TransAm guys also picked up on this and had their hoods adjusted so the underhood air could escape at the back of the hood.

    I agree with computerworks, I don't like things that are nonfunctional. Which brings me to the Air Extractors on '67 and '68 cars. No real value added here. Looks good, but no real functionality added over the FoMoCo production louvers and an increase in drag to go along with it. I guess that they were put on for marketing purposes. If the winning LeMans GT40s had four scoops back there, then if you put four scoops on your street model car, by God it ought to be fast.

    Tens of thousands produced over a number of years vs. less than 8K total production over two years = cost prohibitive.

    And I was comparing American muscle of the ’60s & ‘70s to their modern counterparts.

    Please read my post above (#6) where I make that point.


    Sure I would love to have a functional hood scoop vs. what we have. But it is what it is and I’m not loosing any sleep over it. And the only point I have been trying to make is; American auto companies have been putting on ‘tacky bolt-on’ hood scoops for the last 30+ years. This isn’t new news and just started with the new Shelby vehicles.

    My SGT is a ‘08 mid production run; I live in an area of NC where we have seen temps ranging from the high 70s down into the teens since I brought my car home early last month with no issues. I’m just glad that I haven’t had to suffer through what others with early ‘07 are currently experiencing.

    Its not just the early 07s that are suffering......ive heard of cars into the 5000s having problems.
    Once again...ive got no problem with the hood, like it actually, this is just what ive read on other forum sites.

    I almost bought SGT number 629 (I think it was 629, It was a pretty low number) but bailed on the deal when I went to pick up the car and the stripes were all messed up. The scoop on this car was terribly ill fitting and warped. The hood pins were messed up as well. I purchased SGT number 3960 the next day at another dealer. The scoop fits fine and looks great. However the car has only been driven home from the dealer and has never been out of the garage since. Something tells me that if I drive it much the scoop will warp.

    I believe that the scoops were a last minute "cosmetic" addition due to the fact that they did not have enough time to test new functional hood designs to satisfy Ford specifications.

    Keepin' it nice. No real need to drive it. I also have a 2000 Mustang GT with only 34K miles on it. It sits in a storage garage and gets driven about once every six months if that.

    Hood Bump

    #41XX, with about 2000 mi on it Texas driven, and have not noticed the warping although now that it's mentioned on the forum I think it is looking a little funky. I wonder what it would look like if it were turned backwards?? It would definitely be more aerodynamic and might solve the problem...Then when it warps again, I can turn it around to stock. I think it's only held on by 2 bolts, not riveted to the hood.

    Been away for a while-thought I should contribute something :)
