FIXED THE FLAPPY FENDERS!

Looks great.
Can you post where you found them? -
Those look a lot like the Nissan GTR vents

Don't try to use the rivets it comes with. Get some small pan head bolts, paint the heads black, use lock nuts, and large fender washers, because some of the hood plastic needs to bend to form flush with it, and needs support. I also cut away some plastic in front of it underneath, so there's nothing blocking the free flow of air out. For placement, I used 2" painters tape running down both the crease and edge of the hood, and placed the vent so that the edges run along the edge of the tape. The bottom "V" of the vent ends up being 9" from the top of the hood.

Great write up. Thank you for the info.

sooo where can i get vents like these? for those who installed them how is it working? keep the fender from shaking?? thanks

They work great! Love them, they look cool too!

Love the look. Another fantastic spin on the options available

all that real carbon fiber is giving me a bad case of buyer remorse......

You should not have any regrets, I like the vents you used!

They look awesome! And think about this @2SierraRomeo...
When you park at events or where there are SS fans, you could hang a bucket underneath, with a sign to insert quarters or dollars into those vents for a picture...

Although this looks nice, better than the vents would have on mine, real world testing seems to suggest it's doing jack squat to reduce lift of the fenders. I've used magnets from the beginning prevent them from flapping, but at 100mph today, the passenger fender lifted/bounced a couple of times. Just too much air going under the fender at that speed for a 1" x 4" hole to do much good. The slotted vent would let significantly more through. But, I'll probably fiberglass an extension on to it to catch more air and produce a greater down force.

As far as Fit, Form, Function, I prefer the @gpcustoms application. Where can I get a set?

It seems they can be found here: Front Fender Vents | zero decibel motorsports
Looking at the problem further, I've circled the real problem area. This area seems to have been purposefully designed as a parachute. The air has nowhere to go here, except to push up on the hood. I'll be working to majorly open up this area. I love the look of these side fenders (my '15, not so much the redesign after that), but I believe they contribute to the Sling's drag more than anything by far.

Brother, thanks for the information.
I love this forum and the collective knowledge and intelligence that is freely shared.

As I look at the circled location, the very reason the vents such as myself, @gpcustoms, @kenny_h and others have used seem to work. Directly above this location is where the vents are placed providing a good air flow out of this pocket. As I remember this was the exact area that @kenny_h had lifting on his fenders more so than the front of the fender above the lights.
I also always wondered at what point the magnets might relinquish their hold and allow the fenders to flap. Thanks for the update on the real world test, the vents still are sporty!
-
I have no problems with the lifting fenders because I removed the bar doors. I will be installing the GPCustoms vents as well.
-
Just got to see @Slingrazor s Sling with fenders removed. That pic doesn't do it justice - it really looks awesome and changes whole look...for the good. If I hadn't just gone bat shit crazy on all the carbon fiber stuff - I would do it in a heartbeat!!
-
Wow, when I first looked I thought there was no way that NACA vents would work because you'd be putting more air under the fender. Then in next pic I saw that they were mounted backwards..Ingenious and the best looking I've seen.

Thanks. I'll get it to work like I envisioned before it's all over. But, something you'd appreciate... in the midst of finishing up my annual, it inspired me to cut six new holes in my engine cowling to fiberglass in some new scoops and vents (sick of temp problems on long climbs). It's funny, I can't draw or paint for shit, but I turn into an artist with a Dremel in my hands. Had to get a new Dremel too... it survived an entire two years of fabricating an aircraft, and I killed it installing those NACA vents in the Slingshot.
