Is the wheel well area high pressure at speed?

There may be a slight Bernoulli's effect created by the air flow out of the fender louvers - pulling some air in from the wheel wells.

Or is the idea that heat will flow out of the under hood area, through the vents into the wheel wells?

I don't know - just wonder?

Yeah Dan, I was wondering the same thing about Bernoulli's principle. I learned all about that in A&P school when we were learning about aircraft carbs!
