Remove the plastic part at the strut brace triangle for even more flow (2 push pins and it snaps out). I've datalogged this on other cars and found an 18 degree reduction in engine compartment temps (on a turbo). It's a cheap and easy cooling trick...

More parallel thinking. Been eyeing at that area also and internalizing on what to do.

You've basically answered a question I've had and a thought process which dates back to the muscle car "cowl" inductions that used that high pressure area for induction. How to affect engine bay temps w/o putting non-stock looking vents in the hood? Couldn't figure out if it would pull or push air and what effect it would have.

Quite a few years ago Corky Bell did a Turbo Supra for me so I had the opportunity to follow one of their turbo projects pretty closely. Todd Gartshaw (current director of marketing for Barer Breaks) worked at the shop at the time and owned a Turbo Mustang that was being prepared for a Motor Trend 200 mph article. They did everything in the world to try and get the car to go 200 mph and what did the trick was underbody panels which smoothed out the belly aerodynamics.

Not that I'll be doing 200 mph any time soon. That being said, wonder if the air coming in from the top moving underneath would affect high speed stability.
