Trailmaker, basically I'm creating a heat reduction hood using the stock hood. AEV sells their heat reduction hood for like $1,500 but then you've got the cost of paint as well so depending on that, you're looking at a total cost somewhere in the area of $2-3k. You see heat reduction hoods more on a Jeep, however should be stock on the Power Wagons and not just the Rebel. The ram air style hoods are for air induction usually and while they are good at getting cooler air under the hood while driving, they are useless while idling or off roading where you might have to engage 4lo/hi for an extended period of time depending on terrain and crawling over said terrain.
I got the idea to do this hood though from the Macho Power Wagon which was shown at SEMA like 3 or 4 years ago. When they showcased the truck, it had a redesigned front and rear bumper, hood, sliding headache rack, and stock 37" tires with an upgraded factory lift. The truck received huge applause, however RAM didn't move forward with it and best I can tell, there are not plans to do so. However, I feel the front/rear bumpers and hood should be a stock item on all Power Wagons because of what this truck is designed to do. You wouldn't see so many people going to different front and rear bumpers if they had the ones from the Macho.
So I got to thinking the best way to go about it while utilizing the stock hood and the stamped louvers currently on the hood. I searched for a whole bunch of different options for vents and came across none I liked. Then the Rebel hood came along. The vents on the Rebel hood are functional for allowing heat to escape from the engine bay. A bonus, they are basically the same dimensions as the stamped louvers on the 2500/3500 hoods.
If you haven't done it yet, I suggest Googling the SEMA Macho Power Wagon.
Harpe is right, if the hood is vented heat wouldn't be an issue. So to answer your original question after the long drawn out post more directly. Lol. It's vents over ram air for this indended application.
Harpe, I've got a company who will redo all my vinyl to match what's shown on the Macho for about a grand total and that's also doing an anti glare hood. It's on the list of things to do.
