Aero help
Hi All,
I need to move the engine and trans oil radiators away, so I'd like to know if these are points of *GOOD* pressure, assuming that I'll open an exit for the air in front of the wheel.
PS: engine bay is separate from these vanes
Thank you.

radiators
It looks like you have unused space on either side of the inter cooler.Since this location is right at the forward stagnation point,it would be the preferable location if you could squeeze the other two coolers into those spaces.

Yes I know some cars put coolers and intercoolers, but could it be that some front shapes could reduce pressure in those points?
The 911 seems to have a more squared front bumper, while mine seems more "roundy" there...
Really don't want to put coolers in a low pressure point...
Thank you.

Yes, you're totally right... unfortunately there is not enough space for coolers there... the grille is almost touching the intercooler's pipes there...
Thanks

If you want a visual pressure representation on cars similar to yours go to Bing or Google "image search" using the phrase: cfd pressure automobile....or similar phrase perhaps more specific to your model and make.
https://www.google.com/search?q=cfd+...w=1280&bih=678
Examples of such a search:
Corvette Racing: Inside the GT2 Corvette C6.R
S1.Dynamic // 997 Turbo - aeromotions
If you find that you are not scooping enough air, you can always fabricate something to do so such as the below, but on a larger scale.
Pelican Technical Article: 911 Carrera Oil Cooler Upgrade
It's not too late to ask, so here I go..............why do you want to go though all of this work?

Why do you need to move them from the current location?
What is the objective/goal?

Here is that last idea expressed on a Toyota Supra (different year than Wolf_TM's Supra).
Toyota Supra - Type Cars
It appears to be a corner scoop, yet vented like an "air curtain" to perhaps prevent excessive pressure build up while turning into corners.

I see what you are thinking. To be honest those opening on your vehicle serve no purpose but for looks alone and create additional drag on your vehicle.
You can do three things with those holes:
1.) Close them off and try your best to fit the curve of your vehicle.
2.) Catch the air and route it to your brakes.
3.) Leave it.

As you see in this picture they are routing the air around the tire at a nice steep angle.

I need to increase the oil cooler size, removing the current one in front of the engine radiator.
Thanks

That's my suspect too... but it is also true that Toyota put the airbox feed in the left opening, so probably is not just for looks and some pressure is there...

Not possible!

I already catch the air for brakes with 2 duct beside the central intercooler
I'll probably try to increase flow there with scoops like the red Porsche above...
Thanks
