Quick question
I am thinking of doing a grille block on a couple cars, but have it behind the grille.
The reasons are:
1) aesthetics
2) protection
3) making it motorized and driven by the radiator temperature to open when more cooling is necessary
My question is if there is an appreciable (noticeable) difference in drag for the block to be flush with a grille that is about 1/2" thick, effectively making pockets vs being flush (and smooth on the outer surface)?
Since it is not an aircraft or race car, but being driven exclusively below 80mph, does it REALLY matter??
