What the heck is with the stock wing..

[jdc1687]

OK..

The stock wing bothers me. It does nothing. It is flat, it does not offer downforce.

The only thing it does in so far as I can tell is hold the third brakelight.. Insight please as this is really bothering me.

It is flat, it does not offer downforce.

Why can't a flat wing add downforce?

 

[Ojas]

Huh?

it does not offer downforce.

How did you arrive at this conclusion? According to the NSX Technical Information and Development History book and other sources, it is functional and does create downforce.

It seems like wings are more plentiful than any other aftermarket part for the NSX. Get one of those if the stock one bothers you so much.

BTW: Even if it added zero downforce, that does not mean it’s not functional. There is more to aerodynamics than adding downforce - reducing drag, for example.

I have no proof, but aerodynamics would suggest that it IS functional. Look at the curvature. The top is flat, the bottom is curved - the inverse of an airplane wing. Instead of creating lift by accelerating air on top a la Boeing, it would seem to create downforce by accelerating the air under it.

try removing it, then drive your car at high speed on a track and see if you see a differance.

What you said is correct. You need no additional proof. :biggrin:

WHAT? The bottom is curved!!!?? That makes perfect sense.. An inverted wing..

Are you sure it is curved?? lkajdslkfjlkdsf I want to go look at my car now..

There is always a type R style wing(oem styled but not oem looking?). I think the stock looks great myself, and yes..logic carries it's a functional spoiler.

 

[03 raw nsx]

the NSX is all about clean lines...the stock rear wing is great, but I do like the 'R type' wing. Both work and do create downforce. As said above the bottom is curved creating negative pressure above. I used to be a A&P Mechcanic...just study basic areodynamics. :smile:

But is a large 'suit case' handle or F1 wing makes you feel better...rice on :biggrin:

 

[khappucino]

i think that the type of wing your thinking of, kinda like the giant GT wings, do indeed give you 'downforce' but you also get tons of drag too, its a trade off between the two, i think the good thing about the oem wing is it has a small frontal surface area and probabably a low drag coef., yet will still give you downforce at 100mph+ speeds :biggrin:

 

[archangel0585]

jdc1687.... I know you "decided" to keep a stock car(as noted in your other thread)... I just want to tell you.. if you change the wing... more will change haha.. it's the first step down a dark dark..beautiful path.

so look back at this moment when you're paying for dyno time to tune your fuel map. just think.... this is the beginning.

now go get a carbon fiber type R wing from SOS

Take it off for good stand behind it and let us know if anything bothers you now. :biggrin: :biggrin:

[heySkippy]

WHAT? The bottom is curved!!!??

Are you telling me you never noticed that while waxing the underside of the wing or making sure it isn't water spotted after washing?

You do wax the underside of the wing, don't you?

:biggrin:

For details about NSX up/downforce with different wings you may watch this .

 

[Jin1976]

About after market GT wings, if you plan to buy it make sure it is already wind tunnel tested for aerodynamic. Might add more downforce in straight line but you don't know what it might do to driving at high speed around the corner. We had student project to check if GT wings are ok to be used in general so we tested a small scale Subaru with the GT wing. The result, no improvement in straight line and the car toppled in cornering.

What do you need with downforce?
How close to the limit can you drive such that you need downforce?
My guess is that if you did drive that close to the limit, you wouldn't be posting a question like this. :biggrin:

 

[whiteNSXs]

As said above the bottom is curved creating negative pressure above. I used to be a A&P Mechcanic...just study basic areodynamics. :smile:

The curve does not create negative pressure ABOVE. The curve, since longer than the top, creates lower air pressure BELOW.

The problem I had with the wing is that I thought it was there just for show, adding wind resistance and not adding anything. My M3 has no rear wing, and I'm happy with that since I only autocross it and drive on the streets.

The NSX on the other hand, I plan to track(I haven't even had it long enough to get it inspected). So, two things about the wing annoyed me..

1: I thought it was just for show
2: It didn't actually do anything, and it would be nice if it did.


And no, I hadn't noticed the bottom was curved, as I said, I've only had the car for a week..

Funny, I would never think that Acura put anything, especially the rear "wing", on our cars for just show. And, sorry, but I like the simple clean look. If I absolutely had to change, I would go with the Type R and have it painted to match my car - but that is just me and I am an old man. Regardless, good luck with that.

I'm an old man too and had the car already stock painted (Magnum gray pearl) to match the CF parts that came years later :biggrin:

The NSX body doesn't really have "fake" vents such as the Mustang. The spoiler does work...I don't know how well, but they intentionly designed it with function in mind. Enzo said it best: "If the car needs a large spoiler put on it, then it was never designed properly in the first place." Hence no stock production Ferrari comes with an "added" on spoiler..ie STI and Evo :wink:

One of the facts you learn while majoring in automotive design.

 

[liftshard]

Spoilers are different from wings.

Spoilers "spoil" the airflow in order to create a turbulent wake. A smaller, turbulent wake has less energy than a large, smooth wake, which means less drag. This is why golf balls are dimpled, and why airplane wings have spoilers on them. Spoilers also control the point at which the laminar flow may become detached due to airspeed, which affects lift adversely.

As for the NSX spoiler, I have no clue whether it produces any downforce. I doubt it because it doesn't appear stout enough to supply much pressure onto the rear of the car. I believe it's a spoiler, not a wing.

 

[loNfastNSX]

Our cars come with a WING!?!?!? COOL!

:biggrin: :biggrin: :biggrin:
