wing flutter

[shorty]

Anyone experience what I call “wing flutter?â€￾ At a reasonable speed of 80 mph (yes here in Texas we have 85 mph speed limits and even in the 75 zones they let you off with 5 mph over the limit) my wing is vibrating. Enough that I can see it in my rear view mirror. This is the wing with no middle support as found on the trucks with a tonneau cover. My QC has no factor cover, just the wing. Just wondering if anyone else has seen this on their 10’s.

Yes sir that is normal

Thanks, good to know, just didn’t want something flying off.
Someone asked me the other day how effective the wing really was. I believe under certain speed the wing is strictly cosmetic. Possibly at higher speeds it may have some effect but say under 120 or so it was just put there to tell world we had a 10. Am I off base?

If you have ever had the truck at speeds in excess of 120 without the wing on it you will experience how much it actually does......or so I'm told

they are smooth at 120 mph!! Makes ya wanna squeeze it some more!!

our beasts supposedly had wind tunnel time durin design.

everything, wing, front bumper & even the side claddin, is supposed to help

90 MPH is where it starts to "squat" to the ground. Front splitter and rear wing pushing the truck into the sweet spot of the springs. I feel this is where the handling gets better on these trucks.

+1!! The closer you look at what ZCx has mentioned, the more you see the genius the SRT and NASCAR teams working together. I like how the side cladding is exactly even with the edge of the wheel/tire. Keeps the air as smooth as possible down the side of the truck. :rock:

That was SRT's motto when making the 10(and possibly there motto in general but I only heard it during a interview talking about the 10). Something a long the lines of every, grill opening, every edge, has a purpose, nothing is just cosmetic.

Guys, you sure gave me something to think about. I have had mine to 132 by speedometer but know so little about the aerodynamics of these trucks that I just couldn’t see the real advantage. Guess had I removed the wind and got up to the 130 range I may have noticed the difference. Think I need a cover to help cut down on drag and bet that would make the wing a little more efficient. Thanks for all the input.

Keep in mind that a bed cover will add weight and cost. However, it will not cut down drag. If you choose to go with a cover, you will need a different wing to retain the downforce w/o added drag. Take a look at the factory trucks with bed covers... thier wings have a different design. Your wing is designed to work with the tailgate up. Look at the underside of the wing to see the integrated shape. This allows the air spilling over the bed to detach from the truck.

Testing has shown that the open bed with tailgate up creates a "Locked Vortex Flow", or basically, a bed of air that additional turbulence flows over and off the back of bed. That is why you see the "flutter" at the wing.

These trucks are VERY well engineered! Not too many bricks go over 150 mph!!:rock:

Cheers!

I remember reading our wings were good for 500lbs of downforce at 150mph. The wing on a Gen 4 ACR is good for 1000lbs of downforce at 150mph.:drool:

gonna post an add for a OEM factory cover w/wing
thanks for the good advice----as usual

 

[ZCx]

i run a flush bed cover, Check Mate by Checker Pro, and my wing will usually flutter but 80 up

 

[VENOMOUS1 RACING]

Yessir Shorty,when your wing starts flutterin, it's starting to apply downforce. It happens much sooner than 100mph. I had a Daytona wing that came on the Daytona trucks and went around Texas Motor Speedway at 120 on balding tires with the rear end firmly planted the entire time. :burnout:
They do indeed perform

really want a tonneau cover even if weight is increased. i am not going to track my truck so weight is not a large a concern as with some other guys. keep a look out for one to fit my '05 quad.
