You might even be causing lift at high speeds due to the excessive air preasure in the engine bay which might be forced under/behind the engine then under the car.

Well everything that goes in must come out. My assumption (yup) is that most of the air entering the bay (front or top) exits over the exhaust headers out the bottom/sides at speed. No wind tunnel here though

Can you post a pic of your engine bay plastics? Just curious how you have it setup.

Well like I said, I have most of mine on, at least all the top edge stuff. Just not the engine cover stuff.

This is dated, but pretty close. I removed the M370 metal cover as well, it's not there anymore currently. Also notable in this pic, bottom right corner of the picture is that fusebox I just removed the other day:
