With all due respect, the hood works. The air does not know what is behind the leading lip. Check the Acura hood that is running at Daytona as we speak. plus the CFD of the Corvette GT Lemans hood.
Without going into the entire aero theory, we have tested the hood configurations and with our on track testing, the front down force/reduction of lift at the front PLUS the increased air flow through the radiator confirmed and validated our hood design.
Also check out the CFD model of the corvette racing hood. The red indicates the high pressure as the air is lifted over the opening behind it. It creates a "Bernoulli" effect that makes a low pressure area behind the leading lip.
the louvers are there for two reasons, One, cosmetics because without a proper tunnel from the radiator to force all radiator air into this opening, the engine would be exposed to view and that would be ugly.
The louvers also offer an additional function to redirect any air the "tumbles" in the area at lower speeds.
This is not a guess, it is a fact. WE tried various hood configuration in the GM wind tunnel and in the Atlanta tunnel with another car and this configuration was validated a number of times.
I am glad to see the Acura NSX hood leading lip that is functionally the same as out LGMotorsports hood.
Hope that helps
thanks

I agree Lou. The higher front lip would cause a greater low-pressure area behind it. Resulting in greater airflow out of the vent. It looks as if you've made it larger as well.
