So I took a different route on this with my old racecar. We didn't want to cut holes in the hood as it was already very light and we worried about their integrity if we put holes in it. So, we took out the small wall between the trunk and the rain tray area. I create a custom fiberglass box from the radiator and then to the rain tray area which then vented out the black rain tray space. The only bitch was the fuel cell was under the fiberglass in the front trunk. Also, before anyone says anything, yes, the strut mounts are installed wrong. We did fix that.
