hood vents

[Grafton]

i am wanting to help keep my engine bay cool with out forcing air under the car while i am driving along,

my idea is to make vents into my stock L hood near where the hinges are (red circles)

any idea as to what vents would fit here?
as i am driving along would they "vacuum" air out of the engine bay and not force air into the engine bay and then under the car?

i searched the forum for info but all i could find was wrx vents that went on a ridge of the hood not a flat area
i like the look and cant seem to find anything aftermarket that doesn't look just like a stick on rice peice.

OMG its like a hivemind up in here :lol: I've been toying with the idea too, popular ones are the LeBaron Turbo hood vents and Pontiac GTP (94-96 IIRC) that people graft onto their hoods...mostly 4wheeler guys.

You can also try the Impreza 22b vents.

Option 1) Aftermarket RS Vents
Option 2) Custom Reverse vents


Option 1) This method involves cutting out the stock vent size and beveling the edges of the cut to fit the vents *FLUSH* style. *NOTE* you have to buy the aftermarket vents there either open-mesh style or slotted, eiether or they will not have the ridged hood line going through the middle.

vents alone. Notice the Gasket around the vents.

Option 2) This method involves cutting the hoods sheet metal, pushing it down and fabricating side walls for the vent. *NOTE* any vent that sits lower on the legacy hood *may* interfere with either TMIC/Strutbar/MAF.

i prolly am going to go the second route, BUT i think i'll make the louvers on a separate sheet of sheet steel so if i screw up i wont need to do as much work repairing the hood, then cut a hole and weld in the whole premade assembly

3rd route - install rear facing mini-scoop and cut a hole in the metal underneath.

That way you avoid having to bend metal, or fabricate the sides.
(think of it like a mini-sized version of the below pic)

4th route: buy a hood with a vent already in it.

did anyone notice the backwards hood scoop

[decke48]

yes. and did you see the FMIC. the reverse scoop is to help the heat excape from the engine bay

theres not much to screw up.. masking tape and a cut off wheel is all you need. just measure and cut. bend them to the point you want and weld in some side walls.

OPTION 3 isn't really what Gafton is asking for...
OPTION 4 is really no help considering the cost of importing a hood from japan. BD hoods are as rare as a 22b .....

[Huffer]

Option 3 is definitely the easiest. I didn't say stick a WRX scoop on backwards - I said use a mini-scoop and flip it backwards... it's the inverted version of option 2 but the install is a lot easier. No welding or fabricating required, really. Cut a hole, clean it up, install the flipped scoop, add some mesh to stop leaves and stones from falling in and you're golden.

Flip this backwards:

Hey here is a thought that requires little or no cutting, just some washers. Some of the drift AE86's I have seen have the rear of the hood raised about a 1/4" to a 1/2". That would create the required flow, with no cutting, and adding space over the top hats for the TMIC and the strut bar. The front latch should be able to tolerate the slight change in angle. Again just a thought.

[Huffer]

Ah, hood shims.

Old bracket racing trick, I've seen someone do it on a WRX though...was kind of on the fence about its looks.
