Side Exhausts and aerodynamics with pics

Well here is some pics for you.
The above pics were done with epoxy but have now been welded. Below the upper guard vent has also been welded in. The front "marked out vent has not been started but is very interesting. It will be connected to two areas. The front section will connected to the area above the front fog lights in the high pressure zone.
This will lower lift and drive the air over the top side of the guard creating more downforce. The second part of that opening will be connected to the area just in front of the inside tyres. This is to lower the high pressure and reduce turbulence going to the floor. Dive planes will be used on the front splitter help suck away the high pressure air from the other side of the front tyres.
So the front guards will have three separate (4 vents in total) venting points to lower pressure and turbulence which leads to better floor performance.
Definitely lost somewhere. In (deep) Space sounds really good to me.

The bonnet is getting a slightly bigger vent, the sides will be of the same design as the side of the head lights. So by having this similar style and it of course the headlights are also recessed,this hopefully ties these features together. For optimal cooling an aero benefit you would raise a lip before the vents to create a low pressure zone after the lip to further help air extraction. However due to the fact that all changes to panels on the 928 are recessed. Look at the scuttle panel, headlights, door handle and even the hatch glass I will stay with just recessed vents.
As to how to fit the bonnet vent, that is pretty tough, I dealt the distortion in the guards but they have curves which make life easier, the bonnet won't tolerate as much. There is no room to hammer and dolly the vents down the sides. So I was thinking about spot welding and epoxy which would be JB Weld as body adhesive seems to change with temperature. Then maybe you use the finished bonnet as a mould to make the skin in CF.
