The chart would make more sense visually if the negative numbers (unterdreckebereich) were below the x-axis.
Curious if anyone knows the context of this aero pressure map. I've referenced it in one of my posts & an aerodynamics specialist had a difficult time believing it. There are variables in the testing facilities such as closeness of the walls to the object being tested. This is a very old pressure map & if the testing facilities are anything like the quality of the car being tested, then things have drastically improved. It's probably obsolete. Maybe we give it too much credit?
I use a ducted extractor right behind the radiator that creates its' own low pressure area by sticking up a bit over the height of the hood. I also have vents in the hood as far back as possible to relieve under hood pressure and provide some heat release, should be a great defroster;)

😂 Operator error! Tried to post pictures with phone, it did not work, iPad, same problem both GT and Rennlist app. Finally used web site on computer twice! By God they made it! Sorry about that...
If you take a look at the areal of your intercooler vs the size on the air inntake in the bumper, it is 3/1, and that makes the air go slow true the intercooler, and that cooles bether than a huge hole that makes the air "roll" in front and making the air block the IC.

And it looks bad..
just my 5 cent.
Which car are you referring too?
My .5c is that vented nose panels do no real harm on a street driven car. On a track car, then some hood vents are pretty much a must. Ducting and more precise modeling is better still.

On a standar 951 duct to intercooler.
Ducting to get hot air out is a good thing, as long as it`s placed in the right places.
