Anyone know the pattern on the fixed wing?

Our '05 SRT has one and I love the look.

Someone told the wife, they have an '05 SRT and it has the moveable wing.

What was the pattern, early/late, trim option etc?

I'm afraid that the 'someone' has no clue what they are talking about!!! But I can also guarantee you that it will not be the last bit of mis-information that you will hear...dealers included.

 

SRT = Fixed wing
non SRT = Moveable Wing

this is not an option that is the only way the crossfire comes... changing this is costly and I do not know anyone that has done it either way around...

 

Someone here on the boards has put an SRT wing on a base/limited, but I don't remember who.

Umm. I think they still consider the movable wing a wing. It does create downforce, because its angled down. It might not be a aerofoil, but the angle is what causes the down force. Ever stuck your hand out the window and put it level then moved it on an angle. It will push your arm up or down.

The "they" is Chrysler. And what does the cross section of the movable wing look like? I know its thicker in the front. so. based on that i would still consider it a wing instead of a spoiler. The purpose of the movable wing is to create downforce, and not spoil the air pressure like a spoiler does. There is a gap under the movable wing so the air flows under it just like your diagram. It might not be a perfect aerofoil design, but it is a wing and not a spoiler. If it were a spoiler, it wouldn't need a gap under it, and it would look how the picture of a spoiler looks. The gap is let the air flow under it and create a low pressure.

 

I thought I had it right, fixed wing = '05 SRT only.

BUT, the wife said that and he swore to her his '05 SRT came with a moveable wing. They didn't make an '04 SRT right??

Correct.

Have your wife introduce you to this guy...and then insist on seeing his SRT. He will either disappear...or shut up.

 

The SRT6s came with fixed wings only. All other Crossfires have motorized 'wings.'
Most SRT6s were model year 2005s. There are 3 2006 SRT6s that we know about. All of them have fixed rear wings.
They may not realize they don't have an SRT6. A while back someone got on the forum and said they had a new SRT6, etc. Once we started asking him questions, he realized that it was not one.

Exactly, that is a spoiler, the Crossfire is a wing. Were not debating the definitions, but the function of the Crossfires wing.

When did he say that? But just because he said it doesn't mean it's true. You never heard an expert be wrong before? They only things you provided were the definition of a spoiler, I know that that is, and it's not what is on the Crossfire. The movable wing is a wing by definition. What part of the definition of a wing does it not meet?

"Wings perform very efficiently, generating lots of down force for a small penalty in drag".
"The wing works by differentiating pressure on the top and bottom surface of the wing. What a wing does is make the air passing under it travel a larger distance than the air passing over it ".
it does because of the angle and the different thickness and the gap underneath. The air flows over the angled top at a different speed then the air flowing under, causing a differentiating pressure.

Again it might not be a perfect aerofoil, but it does have all the same properties. Making it a wing and not a spoiler.

Ok, you convinced me. So is the purpose of the "thing" on the back to act like barriers to air flow, in order to build up higher air pressure in front of the spoiler, or to create down force by the angle and speed of the airflow?

 

Romio,

The basic difference is that the "Spoiler" is at an angle and creates down force and also drag (because it is angled). There is high pressure before the spoiler coz of the angle.

The wing (not angle much) produces down force (high pressure above the wing and low pressure below it) because it has the shape of an aerofoil and does not produce that much drag.
