Little aero secrets
Aren't those amazing? I like arrows and rainbows. Did a little mod to see how bad could be and quite pleased to how it turned out.
The first set of pics is flow speed and second set are graphical pressure representation.

I've been testing since yesterday around dinner time! I think I haven't done anything else since! Tested close to 50 configurations, only takes 1 minute to draw the change and another to test.
Added Nascar style WB.
DJ Khaled "anotha one", this one a spoiler feeding a full size wing, cut lower boards and raked body slightly lower.

Can you test the difference between two wing profiles? Between a tall shallow wing and a short deep wing? One wing is 3mm taller vertically and 3mm shorter horizontally than the other when looking at the side profile.

That is quite interesting. With the shorter WB you get a smaller pressure area but the pressure is higher and you also get a smaller low pressure area behind the wing. But why is there a separation between the two pressure areas?
The reason behind the question was that my new body has two cut lines for the wing. Both lines give you a 40mm cord but one has the taller Wicker Bill and the other has a longer horizontal surface.
Thanks for this though, It is neat to see.

No problem, just took 5 minutes to do it all!
The separation I think because there's a vortex from the spoiler leading edge/boot lid but it's just me theorizing unfortunately I can't zoom in.
Hope the manufacturer doesn't get mad at me because it's a silhouette of a racing body still used today. *waving white flag screaming fair use*

Just as I thought. Having two cuts in the spoiler increase negative pressure behind the third element. Like this:
The problem is using it to our advantage... I can lay down the top part of the spoiler and get rid of the big pressure area, increasing downforce at the rear bumper! Watch the difference.

Am I to understand that in your diagrams, the larger the orange patch, the greater the pressure on the rear wing?
Also noticed that in each diagram your wing starts at the rear of the upper deck (near enough) where we only have a small amount of overhang normally.

That configuration is from J. Groskamp. Non perspective corrected but tried my best from available pics.
And another quick one just to show you.

Affirmative on the first paragraph, it's on a scale of blue to red, where blue is lower pressure and red is higher. Higher pressures mean trapped air obviously.
