i wonder if those extraction vents on the hood might feed hot air into the cockpit with the top off on warm days?
do any of the posters with wheel well vents drive in the rain or dusty conditions? might this make the front trunk dirtier?
There is no *might* about it. Yes, even with the screens used on some, there's a lot of dirt in the front trunk.
As for the hot air over the windshield, yes, you can feel it but it disperses pretty quickly.
One would have to run a couple of tests with a few sensors around the car to get exact numbers.
However, my point still stands. I'd rather have the air up and away than under the car where it will create additional lift.
Not much of a problem for street driving, but at the track, you'll want all the help you can get.
A 914 can get pretty "light" above ~120mph ...
