How did you install your hood scoop?

Post subject:  How did you install your hood scoop?
I recently got an aftermarket twin snorkle hood scoop from Mopar by Crane. The fiberglass scoop's quality and finish is excellent. They don't include mounting studs, but it has a wide flange turned in about an inch along the bottom edge.

Sarah Crane told me some folks rivet them on, some use sheet metal screws, and others use barrel nuts to add their own studs. Regardless of how I mount it to Aaron's Dart Sport, should I put some type of weatherstripping material between the hood and the scoop? If so, how will water run out from under the scoop, since it would be entirely sealed in? If I don't use weatherstripping, what will prevent water from seeping into the holes drilled through the hood for the mounting screws/studs/rivets? Wouldn't that cause rust to develop around the edges of the drilled holes? Not to mention how it would soak the underhood insulation padding.

How have you guys with scoops done yours?

The last scoop that I installed, I made a cardboard template of the base from the inside edge of the flange then used the template and inscribed it on the hood with a fine marker. Next I cut out the shape with a cut-off wheel but I guess you can use a jigsaw with metal blade or sawzall. After cutting I test fit the scoop- pushing the scoop out from the bottom of the hood. I filed down any irregularities in my cut and then riveted the scoop in place. Finally, I grinded the rivets as flush as I could without grinding them off completely and put a thin layer of body filler around the mounting crevices. Let dry, sand down and repeat as necessary until you get a seamless scoop, perfectly blended with the hood.

Thanks for the reply Russ, but this particular scoop has a flange that turns in under the scoop, rather than turning outward. It is completely concealed under the scoop. The hood is already painted, so I can't do any visible body work to the surface. The scoop has to be mounted from above, sitting on top of the hood. I don't intend for it to be functional, so cutting out the hole in the hood is not necessary. I am just uncertain how to deal with the water that might get trapped inside the scoop.

So if I understand correctly, with the flange concealed underneath, there would be a way to put some bolts under the flange allowing you to only drill some minor holes in the hood to mount it? (sorry, just trying to visualize this in my head) If that is the case, water most certainly will get in there so what I would do, again without damaging the hood much further, is to find out the low points where this water will run and sit (may actually have to install the scoop to test this). After that is established, you could drill a few extra holes to allow the water to drain. I would also make sure that it wouldn't drain onto any electrical components in the engine compartment. Another option could be that instead of mounting the scoop tight against the hood, you could use some thin enough spacers (thin enough to give you just a small enough gap that it wouldn't be unsightly) to allow the water to drain from all around it.
Just a thought, hope it helps some. :wink:

seam of sealer under the lip after drilling the holes and before tighteningh the screws or riveting??

You can also seal well the side parts of theflanges, but in the back partuse some spacers (small, but big enought to let water pass), so everytime you open your hood any traped water will slide out the scoops.

I understand the rationale for "shimming" up the scoop so water can run out under it, but I prefer that things fit tightly. I don't think I would like for there to be a gap under the scoop along the sides or rear, since they are highly visible. I might try to leave a slight separation along the front mounting surface, because it is tucked up under the snorkles and not easy to see. Actually, that might be the best solution, since the car's stance and the shape of the hood cause it to slope downward to the front. That would probably allow the water to escape. I just need to make sure the holes are sealed off properly.

I'll let you know how it turns out,
Jerry

I thought maybe some of you have done this before. :?

I got a single big scoop in the centerof the hood, but the air intake is half inch up from the rest of the scoop, so I really don´t got that problem, also is a functional scoop.

This picture doesn't really do it justice (crappy cheap camera :roll: ).

It took longer than I thought it would, but it was only because of the way I do things. Measure and check about ten times before drilling or cutting. This is a fiberglass scoop sold by Mopars by Crane. Very nice quality, but we had to modify the leading edge slightly to get it to fit tighter over the ridge running down the center of Aaron's Dart Sport hood. A flat hood, like some Dusters I've seen, would have been OK.

We wound up drilling 7/32" holes through the hood and 5/32" holes up through the scoop's flange (tucked up underneath out of sight). We placed a little dab of silicone on each hole, top and bottom, then fastened the scoop down with #12 stainless sheet metal screws. Much easier than trying to use bolts/nuts and cheaper than rivets (don't have a rivet gun).

I'll try to get some better pics posted someday, but you get the idea.

Now, Aaron wants a go-wing... 8)

That came out really good! A go wing would be the ultimate way to hide a /6!
