Your scoop is doing the opposite and offsetting the gains from the dam. Raising the rear of the hood is iffy if it is too close to the high pressure zone at the base of the windshield. Think about the NASCAR guys using the windshield base cowl induction for power gains. Same high pressure as a scoop without the drag.



this is pretty cool, I did not know this, I thought it was more for aerodynamics to have the flat hood in nascar with the windshield base cowl



The NASCAR cowl intake system serves two purposes. It gets a little higher pressure air into the engine (poor boy supercharging) and it relieves the pressure at the base of the windshield.

Very few high speed cars have conventional hood scoops outside the drag racing community.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
