How Functional is a Functional Rear Wing?

[EFI]

I cannot feel any difference in mine with regard to downforce.

I definitely did. Not so much on the street, but on a track doing high speed turns you can definitely feel the back being more planted.

lol i was confused also but i did my googles

Interesting. I stand corrected.

Seems like a lot of effort and money for something that still makes negligible downforce. Kinda gimmicky in my opinion, but then again, that's what Roush is good at selling.

Hey, I wanna watch this too.

Best way to see how the wing works with said car is to take it to wind tunnel and get reading at certain wind speeds and see how the downforce changes. i did it with my Roush and its interesting info as i have the active carbon fiber wing.

Please share with the class your findings. Im curious what the numbers were.

I'm puzzled here....
I'm 99.999% certain Roush does not sell a wing (spoiler yes, but not a wing) nor do they sell an active one at that. I could be wrong though; I don't follow Roush offerings closely.
Could you share a picture of your Roush active wing?

My bad spoiler not wing. I keep forgeting theres a difference. But it is designed to change downforce. I need to dig up my results from the wind tunnel session i did so i can show differences.

Let me dig up the results from the session i had last year.

I can tell a difference in my MPG after installing the FP Swing and gurney flap on my car! It dropped 1 or 2 MPGs. I can also feel more drag on the interstate at high speeds. It is the best looking spoiler on a Mustang though!

I was thinking that at typical highway speeds, a change in MPG is likely to be the biggest impact most would see to any change in aerodynamics. It is much easier to add drag than it is to add meaningful downforce.

Thanks for posting this, I was afraid I was missing something but it turns out that’s not the case, and while my E85 mpg will be crap (I don’t care), there’s zero reason to make it any worse unless it’s for aesthetics only, because there is no added functional benefit on anything but a dedicated tracked car.
