But as you said, the point of a cowl is to draw air in not blow it out. By having a 'flow through' design you could degrade or eliminate the performance effects of a cowl induction hood. also, engines aren't the smoothest of surfaces, even with the nifty covers that they now have. lots of little bumps and valleys to create drag. How much? I have no clue, but enough to be undesireable I bet. I'm not an expert on any of this stuff so don't treat it as gospel.
Tell ya what, if camero or Fbodfather gives me the CAD files of the Camaro, I can try a simulation and see what happens. You guys use UGS at GM for that stuff don't you? If not I also have SolidEdge and SolidWorks availible (I love this school!). Now, the model would have to include the engines you use, as well as the design of the entire front end, such as headlights. In fact, just put everything you have onto a disc and send it to me. No? I promise I won't tell anyone what those features are, its just for doing a little simulation. Still no? damm, it was worth a shot!
