Hello ecomodders! Who knows what's got me up pondering aerodynamics at 4:30 am... But! I am planning to do a (partial) lower grille block, and have a ducted opening... I recall seeing in a thread that an opening 1/6th the radiator height will do, can someone verify/amend this?
And also, it should be alright to cover the area in front of the A/C compressor? I rarely ever use my A/C to begin with, but I need it to remain somewhat functional for defogging purposes.. Down the line I'll consider deleting the whole darned thing, but for now, it remains
In the picture attached: the blue area is the radiator, and the green, the A/C compressor.
