Hello everyone,

After falling 8 feet from a ladder and messing up my foot/ankle I find myself on the couch with plenty of time to think .

The way I understand it, curtains serve two purposes aerodynamically . One, by moving air out of the high-pressure frontal area making that area smaller . And two, moving that air through the front wheel well and creating the effect of having a front wheel skirt . I know there's a lot of technology and math involved in the placement and direction of this moving air, but my question is, is there any disadvantage to moving the air out of the frontal high-pressure zone, without having it perfectly aimed to create the virtual front wheel skirt?

I have an idea for ducting air from my front bumper/valence into the front wheel well along the contour of the inside edge of the valence. This would exhaust the air parallel to the body of the truck but may hit the outside edge of the wheel . Maybe even 1/4 of the width of the wheel . With some creative tin work I could maybe get it to clear the wheel and hope that the air already moving across the front quarter panel's would help push the exhausted air back where belongs.


I guess I'm thinking about this like someone who makes an aero cap with only a 7° slope. 12° would fit the template better and there would still be turbulence at the back of the vehicle at only 7° , but there would still be an advantage, right? So, would ducting air out of the high-pressure zone in the front create enough of an advantage that the penalty paid for not having it exhausted correctly wouldn't offset it ?
