Heat soak - vented hood options that are not "louvered"

dmhenderson

Edit: Just want to clarify I'm looking for venting options due to my FI build. I'm looking for solutions that take the intercooler into account.

I'm not really sure whether this thread belongs in here or in the "body/exterior" forum but I figured I'd start here as I suspect I'm not alone. If a mod thinks this belongs elsewhere, please feel free to move it.

So unsurprisingly, I'm having radiant heat/heat soak issues especially when the car is pushed hard and I'm looking at more engine bay venting before I look into a bigger oil cooler/radiator/other cooling options whatever. I already have the vented fender liner from GTM so a hood scoop would be a nice way to get some air circulation going.

Thing is, I'm not crazy about the vented hood options I've seen posted here (carbon signal, seibon etc). I really don't like those diagonal vents as it kinda ruins the lines of the car - no offense intended, just my opinion.

I ran across this on my facebook feed (not my car):



...and it turns out this is a non-functional scoop - ugh. Is there a hood that looks like this or the old 350z vented hood style? I've been told modifying the stock hood (even with a fantastic metalworker) is a bad idea for several reasons.

Any ideas?

What are these vented fender liners you speak of?

I remember seeing a DIY for it a while back, but I didn't know there was a commercially available option

GTM sells one if you don't feel like DIYing it.

OP, I'm with you. I'd love some venting that isn't quite as noticeable as the options that are out there.

Well this came up yesterday because apparently sticking hood scoops all over mustangs is all the rage

Would be tough to take a picture of because of where the vents are. I'm sure you can google the GTM stock picture.

I'm surprised there aren't more understated options. Oh well.

Some NACA ducts like the gtr would work if we knew where to put them. I'm not convinced any of the aftermarket hood makers have done any more testing beyond "the vent looks cool right there". I'd hate to put the vent in the wrong place and make the situation worse.

I doubt that scoop would do much good even if it was "functional". Most cars have a low pressure, "dead" area close to the hood. The area at the bottom of the windshield is usually higher pressure, hence the "reverse" inlets/scoops that you sometimes see.

If you have a scoop to hide the hole, it doesn't have to look real pretty.

With the way the Z is shaped, I don't know if NACA ducts on the hood would actually pull air in or whether air would just flow right over them.

I was warned by several people not to modify the stock hood because it "wasn't safe" but I'm not sure why that would be short of possible (?) hood latch issues.

Would it be possible to have a custom scoop like the one pictured above fabricated and attached and a hole cut into the hood by a really good body shop?

Sure, you could have a good shop make some kind of scoop. I think the one in the pic is too far back. My guess is that the best solution from a function standpoint would be a vent with an extractor/louvers in front of the motor to give the air coming out the back of the radiator a place to go.

You can do like Synolimit did here & heat will pour out of the hood. Custom hood vents

I like that concept and placement but I still think I'd want a scoop or something on top of that so that if I get caught in weather, the engine bay isn't directly exposed.
