Well...on the top of my post-conversion lists is blocking off the front grill and such, but that's more to keep the weather out than anything.

I'd assume the opposite as you, though...there would be pressure buildup under the hood, and it would want to push out/up the hood, not the other way 'round.

The/my Fiero is a good example of this...if you get going fast enough, the air pressure pushes the spring-loaded pop-up headlight doors open. People who like to drive fast have to vent the pressure one way or another. (it's designed to exit beneath the car, but this isn't enough at high speeds for what's being forced in through the grill)

Anyway, there's no real point to allowing air to flow in under the hood in an EV, and multiple reasons to prevent it...making answering the question moot.
