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?
