Part 4 Custom Hood Vents

I added a pair of engine-bay hood vents to improve under the hood temperatures.

With the hot air from the radiator and A/C nicely ventilated up and out through the hood vent, I thought that the reduction in airflow thru the engine bay might be lacking in some conditions, mainly at low speeds and rest. I've seen in some Superformance and FFR Type-65/Daytona Coupes some vents added to the top of the hood on each side of the engine. Good functional designs I believe.

I decided to add one vent above the engine on either side of the hood bubble and make the shape of the vents complimentary with the existing hood design and lines.
Although my engine vent shapes may look like NACA ducts (Cool!), they're reversed in direction and are actually vents instead of scoops that NACA ducts are designed as. Venting may not occur during movement of the car, but are more designed for static-car hot air venting. I’ve already seen heat waves exiting the vents while at stop lights and can feel the heat exiting when the car is parked with engine still hot.

D8YTONA Build Custom Features Explained - Hood Vents

I decided to use the same bright-aluminum mesh screens to fill the vents and be complementary to the vent screens normally used on the sides of the engine hood and in the rear cove crescent vents. No need or desire to add a different vent screen or louver design.. Determining the exact shapes of the two screens, then constructing a press-molds using press-board material and making the screen pieces. This was done before the body was painted.

Now with the body painted, final fitment with slight adjustments, followed by mounting from the underside with clear RTV gives these results

Unintended results provided an "interesting view" of the Coyote engine with some unique coverings that will be Explained in a later post.

This is a really innovative mod, I have been considering hood vents but this idea made me think mesh might be the way to go. Well done and really well documented.
