High speed stability issues

At 120+, even though it’s tall, I’d wonder if the scoop is even getting into the air considering the blunt front of the car is creating a big vacuum area at the front of the hood. That’s why a lot of vehicles have vents near the front half of the hood, to suck the air through the radiator and then out.
That’s why a Chevy cowl hood works so well, back by the windshield, what air isn’t going up over the car is getting pushed down to the base of the windshield.
I’m thinking 33IMP is in the right zone. Keep as much air out from under as you can.
