Also I am re-evaluating my grill intake air as the temps rise, wanted to get some opinions on using a velocity stack as a grill air intake. It is 8” diameter at the entry point and 5” at the back point. I know one big hole should be better than a bunch of little holes.
The velocity stack will have ideal flow.Any textbook on fluid mechanics will have either photographs or schematic diagrams of these beauties in action.
I have a form of one on my truck,with the addition of a surrounding toroid to streamline any flow away which doesn't enter the 'grille.'
The inner diameter just has to be adequate to ensure enough flow volume.
I'm at about 1/12th radiator area with mine.Good so far.
