Made luvered hood vents

[RipperXX]

So I want honest opinions of them, and if you think I should install or do another set differently?

I think installing them under the hood and having a trim ring around the louvers would look better than having the whole thing exposed, It would have a clearner look kind of like how people put trim rings around hood dumps, side exit exhaust etc... Nice being different though should keep temps down along with making sure everything is sealed around the radiator/intercooler so it all goes through the cores.

I'm not sure I will use these. I might make a wider single one. I want to carefully choose, seeing as how once the first cut is made your fairly committed.

This is a no go. Looks like a cheap heater vent to me .

Is it the two section thing?

I'm open to suggestions, I'm thinking much wider and with fewer louvers.

What will keep rain off of the engine if you have vents in the hood? Its what keeps me from venting through my hood.

It's hard to find a hood vent (or vents) that look decent with the stupid OEM hood hump being there.

I wonder how these would look?

I like that they look similar to the galant vR4 vents.

I would install them from the underside for sure, by either gluing them on with window weld or sticking them on with 3m double sided tape to avoid having to drill holes for rivets.

The idea of vents is to draw air over them to pull the air out if you have them upside down in the car then no air is going over the raised parts and there for not pulling air out and there is a small possibility it would let it in, only when being in 1 spot and not driving would it let heat out

 

[spyderdrifter]

Not for me personally. Although nice to see someone building their own parts (or at least I'm assuming you did), they don't look like they would work well. If you redesigned them to work efficiently, and placed them in the proper location, they probably wouldn't turn out bad at all. So in the end, a good attempt, but just needs to be planned out better.

Not a concern since it sleeps in my shop. And I have heat shields, etc. over the exhaust manifold.

I wonder how 4; in a similar shape as an EVO - located right over the exhaust manifold would look...


Can they be made with different end shapes?

I actually think they look like vents on the side of a wall for AC or heat in a house or something the side tabs welded on are pointless and wont do anything

Actually, I took compressed air and blew over themy with and without the strips on the side on a stand simulating a hood and they seemed much more effective at pulling a string up threw them from the underside with the side strips.

all its doing is narrowing its path, the problem is not just blowing air at them there but knowing where the correct place is for a low pressure zone to pull it out on its own as you cannot be 100% sure its going to work the same

We make several different vents, they're all square or rectangular. BUT as a side project, I could ask the guy running the CNC laser to cut just about any type he can draw up. No idea when he would get caught up enough to get to it though.

You're right. But I'm limited to what I can do to design and test them without cutting up the original hood and trying different designs. I could test with something like this http://www.valworx.com/product/low-...-30-h2o-bm/low-pressure-gauges-25-lower-mount

thats the thing when you do this and no one else has! you have to take a chance and just cut stuff up and see what works

I think I'll order one of these gauges, I spotted one that reads pressure and vaccum in inches of water. I figure I can just run a nylon line taped to different locations both above and below the hood. The steel hood could be repaired...I doubt it would ever go back on the car other than for than his testing anyway but I think I'll look for one that's not in such good shape with near perfect paint for this.

 

[FIBA M - EC17PSE]

Make sure to keep this updated so everyone else watching this can see your progress with it all

 

[RipperXX]

Just ordered the gauge for just under $40

Miljoco LP2507L420 2.5" Low Pressure Gauge, 1/4" NPT Lower Mount, Range Input: -30 - 0 - 30" H20

From Amazon, should get it on the 29th. Once I get it, I'll start recording locations of readings and what they are at 3 speeds, 30, 60 and 90mph sounds reasonable.

Someone who's good with graphics can maybe help with plotting the data? Otherwise you guys are going to just get MS paint or scanned hand drawn representations.

I'll chart the locations in inches from left to right, bottom to top. So anyone else could use the data on a 1Ga.

 

[FIBA M - EC17PSE]

Sounds good, its good to learn all this as you can then help others in the quest of these, good luck with it all buddy

Just copy the gvr4 hood vents they work great! I had a friend cut them off a Jdm hood and ship to me for my gvr4. I have some extra vents if u want to try them or make copies let me know not using them.

I have PM dsmkauai about the VR4 vents. If the gauge arrives as scheduled I'll have the it Thursday and can begin mapping pressure on the oem style CF hood.
