custom (functional) side vent in progress

Looking great so far!!

it will definately draw air out of the engine bay. even just a hole with no ducting will draw some air out, as the air rushing over the outside of the car would create a low pressure area and draw some air out, there is a word for this effect but i forgot it. plus, the engine bay will be some what of a high pressure area with all the air being forced in through the grill. robispec has done some work with this.

Why not just cut and put new vent? What is the point of a duct? From what I've seen under the hood there isn't anywhere for the heat to go really so just opening a hole would be enough.

What benefit would ducting provide over just a replacement functional vent with a cut hole behind it?

Would rather the whole thing look like the stock BRZ part, just the black plastic bit as an actual vent.

Hmm, without some CFD at least, the heat escaping may or may not be effective. If you have access to get your model 3D scanned, I have a friend with a 3D printer in SoCal. And I also have a few major carbon / fiberglass manufacturers that could produce your product privately.

Hope I don't come off as too "sales-y" but I have a few personal ideas for aero I am working on and wouldn't mind sharing my connections. No pressure though! Just throwing it out there. PM me for info.

Does all this low pressure/high pressure talk mean its gonna rain?

This is what I was trying to bring up earlier; I THINK the best layman's explanation would be Bernoulli's principle, but I'm not really up to date on my dynamics anymore. Essentially, the air being pushed (or, rather, PULLED) out doesn't care about the shape or path so much as the fact that there is one at all. That's why I figured that a simple hole via hole saw or something would be sufficient to vent out most of the hot air.

The duct would potentially allow for waterproofing or at least protection from water/debris. Although, unless you spray a hose directly into the vent, I don't see much getting in there anyway. It would also definitely look more finished/professional. Would also add quite a bit of steps to manufacturing (and cost)...and weight!

not so much a word, but a law - Bernoulli's
@FR-Slide got to it before me.

HI,


I like the fender panel can come with BRZ Ts or BRZ STI concept type trim
(clean, simple and little bit more aggressive than the stock one)
with mesh grille.


ps. I personal prefer the chrome trim instead of the silver.


Thanks.

Doesn't Bernoulli's principle ignore boundary layer separation? Although, thinking about it, even with boundary layer separation, you'd still have a pressure differential across the face of the vent...

Carry on.

will get in touch with ya. thanks!

I want one of these so bad. I hate the fake piece on there now, way to much visual stuff going on for such a small piece on such a "clean" car. My vision would be just a plain mesh with no trim though the middle to keep it clean. But I'll take what I can get

I think this would be great for the forced induction guys producing lots of heat in an engine bay that it so buttoned up.

👍 can't wait to see final product
