Anybody know if it is possible to make the sidevents real (brake cooling etc.) or would that introduce the possibilty of brake dust/debris adhering to the sides etc.?:cool: and would that change the airflow of the car?

You could, I'm sure, with a dremel tool, make the sidevents 'functional'.

The trick is knowing whether you are helping or hurting. Underhood airflow is a strange thing, and not always predictable. You may make your vents functional, only to find out you created an airflow inversion that changes the way the air gets out of the car.

Batteries, ECM's, things that are in that general area of the car, can be highly sensitive to temperature. So, if you make such a modification, and it makes your battery fail or your ECM fail, it wouldn't be such a stretch for a warranty claim for those components to be denied.

The only way to know for sure is to drop in a thermometer or thermocouple in that area (and other areas you think you are benefiting, like brakes), and measure it before and after.

Or, figure out who did the thermal testing or development for this specific vehicle (not an easy task), and talk to her or him. It's not good enough to ask some "expert" or rely on anectdotal accounts, because thermal things like this are very application specific.

:agree:

Therefore they only modified the incoming airflow to get a better brake cooling at the Sky RL / Opel GT.
New air inlet in the front bumper but the side vents are without function furthermore.

Good point.

I guess I was making the point that many of these decisions (fake or real vents) are not done without a great deal of consideration.

cost

Sometimes it is not a matter of whether or not a benefits study was or was not done but simply cost - how much extra does it cost to make the parts necessary to have the side vent be a live duct for anything from general airflow to brake cooling etc.

On a vechicle such as the Saleen S7 - http://saleen.com/ - every curve and vent etc is very specifically designed to benefit cooling, or downforce, etc - but then on a vehicle with over 700 horsepower, 0-60 under 3 seconds, top speed over 200mph and a price tag in the hundreds of thousands range you would expect that sort of thing.

It is entirely possible that the styling detail on the Sky is and only ever has been just that a styling feature. The "hood scoops" on the 1964 GTO are only decorative - sure they look like hood scoops - but they are soild. In 1965 the hood scoop was functional. On the Mustang the side vents by the rear wheels have gone from non-functional - to functional and back to non-functional - largely as a result of cost to produce, rarely as whether having such vents was a technical advantage to not having them.
