WINGS! Is there a link to pics of the different wings people have chosen to run?

Nope. I had a sheltefed depraved childhood.

Does anyone know the angle that works with the ducktail spoiler?

Has any one every tried this software.

Here's what I am thinking. I have slats on my car that are essentially just strips of 5.5" wide .060 aluminum sheet.

Some like 'em, some don't. Ok, fine. To each his own.

They happen to work well in conjunction with the Weber carbs in sheltering them from the elements.



It occured to me, because of this discussion about rear wings, and obviously there is an affect of the angle of the ducktail on downforce, that if each of these slats had say 1" extension on them and was angled as a wing, it would provide downforce to the rear?

It is going to be easy enough to find a picture of one of the Pantera race cars with the ducktail on it and put a protractor on it and get probably close enough on an angle?

Now every one of these sets of slats costs me about $200. Then I need to match them to the mounting holes to the aluminum skeleton, then send them all out for powder coat. Another $350.

So every time these whims strike me, it's about $600 or $700 and about three weeks worth of effort.


That formula I don't know where to start with. Wanna calculate something with it according to what I just described? Please do?

I want to take a slat and put it in the break and see what it looks like on the car anyway? I might nix it right there that it looks ridiculous BUT I have a sneaking suspicion that it might not be bad?

Certainly would freak out all these Ferrari and Lambo freaks?


The initial thought I have on it though is that if you look at this picture of the slats, they curve a little.

The higher up towards the roof they are, the more they curve. As you come down to the flat surface of the rear deck, they are virtually flat.

That is very subtle and most would never notice that.

Putting a 1" wing on each one would stiffen each slat and probably will eliminate the possibility of the curve and just generally screw up the entire concept.

However, that was my thought of the day.


I get the first cup out of the coffee maker and with regular grind that's a lot of caffeine?

The second cup is kicking in? The little ducktails don't have to go all across the slats, just maybe 20 to 24" down the center? Hum?

Great. Now I'm getting a migraine. Ok, enough thought for today? It hurts.


What happens if the air strums them like guitar strings, how do I tune the sound? Oh geeze...make it stop?

Some of these ducktails are showing at almost 90 degrees.

It stikes me that those will act much like full flaps on a plane and work like brakes?

What are the flaps at when fully applied?

Your powder coater doesn't work by weight..?

Good thought about converting deck louvers to a sort-of rear spoiler. Look at some of the old photos of Panteras running at Muroc dry lake or Bonneville and check out how the airflow as defined by the dust trail separates at the leading edge of the sugar-scoop. Most of it seems to arch far above the deck which is part of the problem with rear spoilers on a Pantera (or similar car). Maybe with the louvers the separation wouldn't happen as soon. Too bad my proposed wind tunnel tests in the '90s at the A-1 tunnel in N Carolina never happened.

In leu of some kind of scientific data for air flow over the car, I'm left with extrapolation?

Well, at least it will look like I knew something and I can just see people stopping dead in their tracks and staring at them and needing to touch them?

I wish I knew where the air stream was on the car?


I remember the pictures of the "tuft" tests that Shelby did at Willow springs on some of the comp cars.

Problem is it's a big circus with a lot of people involve, a photographer hanging out the window of the chase car AT SPEED...ah what the heck, how much is a new photographer anyway. Probably can get a college student to do it as an intern right?

Oh...almost forgot...I need a test track too. Pocono isn't too far?


I'm going to have to presume surface areas are directly proportional to downforce and estimate what the surface area of the ducktails are on the current comp cars I can find?

I would think the sugar scoop adds some lift?


I know these things are going to play a tune at speed? I'm wondering if I should vary the length of them into a triangular form with the shortest at the top.

At least each one will be at a different frequency?


Yikes. At least I won't be bored for a few days?



Got some of those pictures Jack? I did a google search and only a couple of the "publicity" pics come up. Nothing with any evidence remaining?

All you need is 2 things. Yarn and a Go-Pro. Oh, and an open stretch of non-patrolled highway.

I'm really considering fabricating my own ducktail spoiler like on this car.
