Here is another Border unit I found. Seems to be fairly new:

That would be cool but once you find the most efficient piece you wouldn't swap it anymore, right?

That would be completely up to the user. For me personally, no I probably wouldn't swap it anymore. But I would be developing more effecient units to be installed in the most idle locations.

Just for instance or an example: Just because you vent heat from one area does not mean that you can not further increase the venting ability of another area by adjusting one part of the hood to a different unit. IE: Venting over the turbo is increased when venting over the radiator is negated.

That's why I like this hood.

the biggest thing would be in HOW you compliment the hood. If you want to see what hood style might be most functional, look at what is used in professional racing circuits. What i find interesting when i look at say, Le Mans cars, very very few of them use the same style of venting, some dont even have a vent hood at all. Makes you wonder how well the concept has been researched.

But the other issue to think about is if you want air to EXIT the hood you need to have the area on top of said hood to be at a lower pressure than that in the engine bay. That means your air tract coming in from the bumper needs to be well designed. Meaning the use of at least the factory undertray, good sealing and ducting of air as to give it few options of where else to go.

well custom underbelly tray and ducting is mandatory. Air will be flowing to the back of the car at all time. Dmax is the only one that I've see showing results though. That alone makes want to get their hood.

These look a little different. It may just be the smaller pic. But on the blue car the rear hood vents look to be louver'd. I think I may have seen a larger pic of that car as well with the louvers but I can't find the pics.

On the other forum some of the more knowledgeable people noted that the rear "vent" on this hood is in a high pressure zone and the air would go the wrong direction there. Their animation depicting how it works on their website was also ridiculed. I'm sure it does a much better job than a stock hood though. :D


Don't forget the PanSpeed hoods.

Don't have pics of the Type I.

Type II:

The other forum has been shown to be full of crap on the most part when it comes to aerodynamics. If you can find a member there to explain themselves you'll make me happy. As of now people like to read diagrams and evaluate them without a single ounce of knowledge.

Most people who claim the high pressure area are looking at an old diagram from Mazda and they go off on high pressure areas and how it will create a vortex and push air back in but I don't see how that makes sense. an elite group of members there are knowledgeable but the rest earned their google search doctorates and are more than happy to talk without prior knowledge.

The guy on the other forum supposedly works at NASA. I think it was evilaviator or something.

About the high pressure zone. You know those muscle cars with the big cowl hoods with the opening in the rear? Apparently air flows back under there to the intake. There is even and FC guy that setup his NA intake that way.

well, they never gave me reasonable explanations. If they somehow find their way in here then they can explain that in detail, that's why I made this thread.

As of now I have yet to see definitive proof of this.

The cowl hood will be elevated closer to the filter in the hood, further forward than the Dmax vent, and it continues towards the windshield which will create that vortex that will draw air into the low pressure pocket (the COWL) and further emphasized by the SUCKING action of the filter and TB(s)/intake system.

The rear vent on the Dmax hood is not remotely similar to the cowled hood. Their openings are in similar spots but that itself does not take away from the fact that the design and effectiveness of one does not apply to the other.

doesn't seem to be similar to this in any way, shape or form:

BTW The panspeed hood looks great. You're going Vmount, right?

So, I bought the AD9 FD hood made for the FC. I'll be testing this hood as soon as I can and will happily post info in here.

I hate you juice, your FC is fuckin retarded (in a good way)

Pheonix7 I'm gankin' your hood.... when I have the funds.... :suspect:

naw man, pick up the dmax hood.
