Nice!
It should help allow heat to escape.

That looks really good. Any chance you can attach some short pieces of yarn to the grill, and get some video while driving?

I drove it around yesterday with the a/c on and it only got to 190 degrees, keep in mind it was 102 outside. When I got to my house, I didn't open the hood to release the heat like I usually do, but went ahead and parked feeling reassured that the extractor would do it's job. I went ahead and put my hand on top of extractor and you could feel the heat radiating out of the vent. I also tried this with the car standing still while on, it worked great with the electric fans! You could literally feel all the hot air coming out with pressure from the vent. I will see if I can make a video of it, gives me a reason to use a go-pro camera that I have only used a couple of times.

If you decide to put strings on your hood vent you might consider to make them long enough to extend past the rear hood edge. It seems to me that it's very possible that some of the heat/fumes from he engine compartment could get sucked down into the A/C-heater ducting/ventilation system.
Thanks

Gary, I went ahead and performed the test with the yarn as stated. You are correct a lot of the air seems to be going back into the vents. If you raise the headlights that changes a little. After performing this test on my car, I went ahead and performed a similar test on my son's Camaro. The same thing happened on his car and his is a 2021 SS.

Thanks for trying this for me. Some have argued this but before I bought my 63 I read everything I could find about the development of various Corvettes and remember that the reason for eliminating the functional hood vents was that exiting underhood air and fumes would find it's way into the cabin. That's why the 63 was fitted with fake vents.

I guess it is a catch 22, because it does work. Keep in mind the hot air goes out mixes with the fresh air and then it is sucked in by car hood. As long as your are running the A/C you shouldn't really have a problem. My main intention for the heat extractor was to relieve the heat temp under the hood. I guess in hind sight you can put some kind of filters behind the grills for the vents. Nonetheless, I have cut the hood and am pretty happy with the appearance. Here is a novice video of car.

The big red corvette book said it was cost that killed those vent. Duntov was very upset because of the lifting issue
