A rear-ward facing hood scoop would basically give you negative ram air I would think.

I have no idea how it will affect the aerodynamics of the vehicle, compared to a forward-facing scoop on the front of the hood or no scoop at all.

Yes I'm aware of cowl induction but most of those are for performance. I just want a little cooler air into the engine. The air wouldn't even hit near the intake at all more like the top of the block. I would just like to know if or how bad it would mess up the aerodynamics.
