Being the the ITR wing is functional, if you were to put a bunch of crap in the back, so the backend squated down a bit, would the wing then generate lift?

If so, how important is it that the ride hight be correct with a ITR? Sometimes it looks like the back sits a little lower on mine...

 

i have 2 subwoofers in the back..and a couple of jackets...so my back sits a little lower..but honestly I dont feel much of a difference

 

For handling......ie. road racing, often times the best set-ups are with the rear set lower then the front. Example: Options Video. EG6 Set-ups: Suspension tunning at track.

 

ITR wing under load? never gotten freaky on the trunk of my itr....

dadooooo....cha........(drum beat for dumb punchlines)

Wassup with all these ARRRRRRRRRR wings questions???

 

Seeing as how the Type R has a 65%/35% front to rear weight bias - you would have to put a crapload of stuff in the back to make that happen. You would also most likely get the front to raise up with such a scenario thereby entrapping more air underneath the car (think of a truck with too heavy a trailer with the nose pointing upwards).

 

Why would it generate lift? It won't do that unless it's upside down.

 

lift? YES!!! This guy put one too many subwoofers in his car, and his wing genertated lift. Let this be a lesson to all!

 

hahaha LOL

 

If the nose of a wing is higher than the tail (relative to the direction of motion of the air), it generates lift. If the nose is lower than the tail, it generates downforce.

Take a look at the wings on F1/Indy cars. The nose is considerably lower than the tail, thus LOTS of downforce. If you look at your ITR wing, it looks about level, but you gotta keep in mind that the air is following the roofline at that point, so the air is moving slightly downward, thus making the nose of the ITR wing point slightly downward relative to the air. (If this confuses you, go outside and look at your car from the side. Now imagine jacking the back end up so that the rear window is parallel to the ground. Now which way is the nose of the wing pointed, up or down?)

From that reasoning, I'd guess that having the rear end weighted down more than usual wouldn't make that much of a difference in the downforce created by the ITR wing. That's my educated guess, anyway.

Either way, going in a straight line at normal street speeds, you'd never notice the difference.

[EDIT]Oh by the way, dropping the rear WILL decrease the front downforce, however.

Good point

 

but is this in relation to the surface it is directly above? In this case we are talking about a stock ITR wing, which is not too far above the "flat" surface of the trunklid/hatch surface. These two items, the wing and trunklid, are fixed in position relative to each other, so there is no way to change aerodynamics based solely on the wing. The changes in vehicle dynamics will be the result of other things.... underbody airflow, etc. So in essence even when the car is scraping only its rear bumper, the wing is still NOT generating lift because it is still in the same orientation with the trunklid/hatch.


hows that for ya?

Now of course a wing that is much higher than an ITR wing, or placed behind the hatch end, may be another issue.

 

Isn't that what I just said?

Yep, very true, but there's a whole lot of "it depends" in there. You can make some generalizations about aerodynamics, but they're VERY ROUGH generalizations. That's why it takes wind tunnel testing, track testing, and Cray supercomputers to get it right.
