yellow opening
I think that your radiator is too close to the grille to allow the bottom inlet to provide enough flow.
To do this sort of restriction,you need an airtight duct as deep( front/rear) as the radiator is high,with a diverging interior nozzle designed into the duct,with no less than 1/6th radiator height inlet opening.Which would require that the nose be pushed forward of its present location.
I would not locate the slot opening elevation any lower than the bottom of the radiator core unless you've got a significant snout out there to help scoop air.
