The pic is another freak circumstance like the Z06. Losing control with the lip spoiler, versus all the fishtail recoveries I'm seeing now with the wing.

If our wing cause a mpg difference that much, makes me wonder about wingless supras.

Still I'm keeping mine b/c I'm photosensitive and hate highbeams, since the stability it provides is in debate. And if the debate is for a 1/4 mile run, I thought that was resolved.

And boo on autoweek comparing a cobalt to a cavalier.

 

Your point is wrong. And I continue to prove this everyday, ****, I'll do it again this weekend when I drive out to Syracuse.

I used to average ~38mpg consistantly (like well over a year) on the highway. Now, I average ~42mpg. Fill me in on what else has changed w/ my car. Wait, let me fill you in...NOTHING...

Believe what you want, but I watch my fuel economy like a hawk. I'm well aware how temperature, altitude, humidity, road condition, incline, etc. play a part in fuel economy. Hence the ~ next to my mpg. Face it, you have no leg to stand on. Stop argueing w/ me and just accept the fact that the wing does effect performance and fuel efficiency. My car doesn't perform better because I get better fuel efficiency, but it sure as hell will trap faster in the 1/4 mile. And you're right, the loss of downforce by taking off the wing will not effect a daily driver vehicle for the most part, nor will it be noticed for the most part. Another reason why I took the wing off, even though I'm so quick to point out it's true functionality.

The increase in fuel economy was an added bonus, and (I will admit) greater than I expected.

 

pass whatever your smokin my way

 

Simple facts, your probably never going to get over those speeds or be in a situation where you need more downforce on your rear tires though a high speed turn unless your going to take your car and race it and take turns past those speeds.

Chances are, your racing the car on the street, drag track or occasionally on the track, but I doubt your going to be hitting turns past 80mph as a rookie racer...

So what to do? Get whatever the hell you think looks cooler because your never going to need its performance.

 

So you're calling me a liar?

How freakin' hard it is to figure out? You divide the amount of miles you drove by the amount of gas you put in. It doesn't take a rocket scientist to figure that out...

V...Basic point I was getting at two posts up from yours...V

 

i took mine off. that thing is hella light

 

Isn't it nice to be able to see out the back window?

 

hell yea. but sometimes it was nice cause at night its in the perfect position to block the headlights

 

Honestly i went from flat to high rise, doesn't bother me one bit.

My eyes are now trained to look for certain things in my rear view. The wing doesn't block anything for me anymore.

 

That's gunna be new to me when I drive home from the track at night....

 

(in a Dr. Zoidberg voice) Hurray! I'm not alone!

 

Oh, I'm definately gonna miss that, but it's nice to not get all the attention all the time anymore. Especially from police that used to always break their neck watching me go by. Good, bad or indifferent; I don't really want their attention unless I'm in danger or injured...

 

i wasn't calling you a liar. if i was i would of said, edubs you're a ******* liar. my point is, taking your high rise wing off, alone, isn't going to net you a 4mpg increase. it doesn't take a rocket scientist to figure that out.

 

Holy **** dude. I went from ~38mpg to ~42mpg w/ the only change being the wing...

Do the math.

I drive the same, my tune is the same...what else has changed?

 

do you drive the same exact way everyday...as in acceleration, braking, cruise control, lane changes at the exact same time every single day? i think not, it's impossible. i watch my mpg a lot as well because i drive probably a lot more than you. mine fluctuates btw 31 to 34 mpg, never more, never less. and guess what. i too am wingless. before and after my mpg was btw 31 to 34...so where the hell is my extra 4mpg?

there are a ton on factors that play into this. you, nor anyone, has any circumstantial evidence that will prove that by removing a wing will increase your mpg by 4. if so, everyone would be ripping them off of their cars...your theory is completely based on heresay.

but hey, believe what you want.

 

Any wing has a lift/drag ratio, inverted means increased downforce with increased drag at higher airflows. Putting the wing higher and into a less turbulent airstream makes it more efficient. But a benefit of the taller wing that I think is often overlooked is the increased stability afforded the rear end as a result of the VERTICAL strakes.

The WRC cars need to land jumps flat or tail-first (relative to the surface) for survival, so downforce on the back end is critical at those velocities. Keeping the back end at the back of the car at speed is where the vertical strakes stabilize like the fletchings on a badmitton shuttlecock.
I have experienced this personally at higway speeds in my STi where 40 mph crosswinds don't destabilize me as much as others. I like my high wing.

 

Heresay? You must not get it...

1) Obviously driving conditions and habits change, that is why I'm comparing over long periods of time. My initial experience of an approximate increase of 4mpg is holding true to my experiences over the last 2 years that I've owned my car. I have no reason to believe otherwise.

2) My car is dyno tuned for my specific setup. That is why I get considerably better gas milage than you do to begin with. To assume that your scenario is similar to mine is ignoring a huge factor in the car's ability to remain efficient.

3) You want me to give you a freakin' average? Okay. My car used to get from 36-38mpg on the highway, every single trip I made that was more than 100 miles supports this; including my most recent trip to OH. Since I have swapped lids, the car has displayed a range of 41-43mpg, typically staying right in the middle. When I drive 150 miles to Syracuse this weekend, guess what? I'll get 42mpg.

What the hell is heresay about that? It is direct evidence...

 

edubs your not going to gain 4mpg from the wing sorry man.

 

Why do I even bother?

Did you even bother to read my posts? I simply stated facts. Believe it or not, it's the truth.

 

I didnt say your numbers arent facts.
I didnt say i didnt believe the numbers.

Im just telling you its not from the wing.
some of it is im sure, but a fraction of it at best.

it has been shown that there is a gain of 1mpg, from driving with windows up, compared to all the way down.
think of the drag involved when your windows are down.... thats ALOT of drag....

your suggesting the wing applys 4 times as much drag?
come now my friend. lets be realistic.

 

Please, shed some light on what else has changed?

I'm on the same tune, I'm using the same octane, my driving habits have not changed, nothing else has been taken out of or added to the vehicle in any way.

What, pray tell, is effecting my fuel efficiency if it's not the wing?

 

I didnt say i could tell you what is giving you better mileage.
Im just telling you what isnt.

 

It's not like I swapped the wing and a month later my milage went up bro.

I drove 500 miles getting my usual 38mpg, swapped the wing and ever since have managed 42mpg on the highway. I'm not saying everyone will get the same results. I'm just saying that those are the exact results I have seen...

Regardless, I'm done w/ this freakin' ****. You have speculation, I have fact. Deal w/ it...

 

*shrug* your entitled to believe what you wish.

but its not speculation. its math. and physics.

a wing aerodynamically tested with a low CD is not causing 4 times as much drag as running a car with the windows down.
just think about it for a second man, think about what happens when you wind your windows down.
the cabin is like a huge parachute....and that only drops you 1mpg....

 

going wingless IS NOT going to get you +4mpg. get that into your freakin head man. if you feel so passionate about your findings then publish a god damn paper and post it on the internet. you'll become famous for discovering this miraculous fact and evey car in the world will become wingless. it's too bad them damn ricers didn't figure this out before...ohwell, guess it's their loss and your gain
