better heat extraction hood

[nonliberal]

Between a 2013 GT hood with the 2 heat extractors on the sides of the hood towards the rear, or the 2013 Shelby gt500 with the big single extractor in the middle. Which do you guys think is more functional?

I have both hoods and care more about function than anything so I'm trying to make a decision between the 2.

To be honest I even considered going custom and having the GT500 extractor added to the GT hood to just have all 3 and not thonk about it again. Lol

how well do your heat extractors work on your '13 hood? I have a '12 and wonder if they could be added to my hood?

 

[nonliberal]

They seem to work pretty well. Even whenen I park the car I can feel the heat streaming out of them pretty good, I'm sure while the car is moving the siphon effect pulls a good amount out.

I run a TVS blower so the more heat I can pull out the better.

When sitting in traffic I can see the heat rise from the vents in my '13. When taking off it doesn't take long for IAT and Cyl Head temp to drop.

I am saving for the tiger racing hood.

GT500 should work better do to placement of the vent and the "lip" at the leading edge of it. Adding that vent to your hood will help but it will not have the lip which creates a low pressure at the vent. I have an extra 2011 GT500 vent for sale if you want to go that route.

I have the Roush and I'm looking for an upgrade as well. Not to thread Jack, but are there any hoods that can come close to the tiger racing seeing as I'm not a fan of it looks wise.

I don't know much about the aerodynamics and flow of it, but the design of the Trufiber A53KR and the A72KR hoods seem to satisfy your concept pretty well. I would think that the ram air function of them letting cold outside air come in would lower intake temps, plus the 2 vents behind them would vent excess heat as well. Cervinis also makes really good hoods that have ram air and heat extractors too.

The vents in the 2013/2014 factory hoods are not designed to be heat extractors, but more of a heat vent. I'm sure it does extract some heat from the engine bay as you move down the road, but it doesn't create enough low pressure to truly extract like the GT500 hoods do.

With that said, if you really want to allow those vents to breathe a lot better, trim the entire hood carpet under the vents out, and you can watch heat rise from the engine bay like a furnace while sitting at a stop light.

Yup, these hoods look sick as hell, are more aerodynamic and weigh lighter than the stock 5.0 aluminum hoods that come in our '13/'14.

I like the stripe layout they did on that to incorporate the 11/12 Boss hood.

My concern with this is messing up the paint by removing the liner, granted its something i really want to do... Plastidip has a heat rating of like 260* if i remember correctly, so i may just plastidip the bottoms as a "protection" of sorts, and then cut the liner out.

I didn't remove the entire hood liner. I just cut away the part of the liner that sits directly underneath the hood vents, the part that catches water when it rains.

honestly that hood looks tacky but function over fashion wins.

IMO dodge has been the only one to get it right when it comes to both

Ahh, i wasnt clear on what I was trying to say lol, i meant just messing up the paint on the vents. How long have you had yours removed though?

Since Oct. 2012. No paint issues because there really isn't much paint exposed.

I did the exact same thing on my black 13', it worked GREAT.

Yup. The vents actually function like they are supposed to and let out a ton of heat.
