    Default How wide is front radiator opening?

    I'm still here, and I have a question that I can't answer myself. Is a 3 ft wide piece of aluminum mesh wide enough to fill the front radiator opening? My car is having all the stone chips dealt with at FZ Restoration. ( http://www.frankzucchirestoration.com/ )

    Approx 28 x 6

    Which mesh are you going with? Do you know the flow rate?

    Thanks! I'm leaning towards this stuff from McMaster: https://www.mcmaster.com/#wire-cloth/=17br0kg (number 9227T52)

    0.063 aluminum wire, 2 openings per inch, 76% open area, should be quite light.

    I was planning to use expanded aluminum mesh, similar to the stock stuff, but Frank Zucchi (FZ Restoration) demonstrated quite clearly with an air gun just how much flow that stuff blocks. I think the circular cross section of the wire cloth will be less obstructive.

    you might think about aluminum expanded metal-very light or
    stainless expanded metal-very durable-
    as small of a piece you will need the weight
    difference is........

    you may want to look at Mcnickols--

    I just used this https://www.onlinemetals.com/merchan...53&top_cat=60# to replace the grille on my Rossion. The center opening is about 31" wide - but I don't know about the Noble. I needed two sheets that were 36" x 12" to do the lower radiator opening, the brake duct area and the upper radiator opening in the top of the clam. If I were doing it again I might buy one more sheet to make it a little easier on materials. Painted flat black and works well. BTW, the whole effective opening area idea - the NASCAR guys are limited to 50 square inches of radiator opening at some of the superspeedways and if you do the calculations the Rossion has about 150 square inches, so even with a 65% opening area like most of the expanded metal has it is still plenty adequate in my estimation.

    The expanded aluminum Frank demonstrated with the air nozzle has ~65% open area, but it was amazing to feel how much flow it blocked. I think the shape of the material (cross section) may be as significant, or nearly as significant, as the open area percentage. A cross section resembling a double edge razor blade would probably flow very well, and the square cross section of flattened expanded aluminum is probably close to the worst.
