Preliminary tests using small pieces of string tied to the mesh in the vent indicate that air flows *into* the "vent" at speeds greater than about 30-40mph, but I want to do some more fiddling before I'm sure. The black mesh is too hot to touch after hard driving so some heat is escaping out of there, or it could just be from radiation from the engine. And sitting at idle you can just see the heat pouring out of it creating a mirage effect.

The reverse scoops on the market are raised at the front which tends to create a vacuum behind it. I wanted something flat. I may fab one up that has more of a lip at the front to see how that looks and works.

No matter what, I still like it better than a non-functional scoop, especially that microwave oven-sized STI scoop.

Did you call me fat?

Nick Koan 2005-08-16 09:59 AM

Is your hearing going or something?

knucklesplitter 2005-08-16 10:01 AM

There's nothing wrong with my steering. A quicker ratio would be nice, but...

Nick Koan 2005-08-16 10:02 AM

:lol:

in all seriousness, do you have steering rack bushings? They really help the feel and reduce slop. You may like them, even if they don't really affect your ratio.

They work that well, huh? Recommend any brands or types?

Nick Koan 2005-08-16 10:05 AM

I forget what MattR and qksubi got, but they really liked them. Whiteline I think?

That's what I would have guessed. If you're just trying to reduce heat in the engine bay during regular driving it'll work great; if you track the car and are looking to reduce aero lift, then it's hurting you.

I'm not sure how it would be hurting anything, cooling or lift, compared to a large scoop forcing air and pressure into the engine compartment, whether it be through a hole (with FMIC) or even through the top-mount intercooler (which doesn't reduce the scooped air's flow or pressure that much).

I could put a flapper door in that is normally open to let heat out, but then closes when the vent is pressurized from the outside. Prolly not worth the trouble. If I'm willing to remove my STI wing then I'm obviously willing to live with miniscule (if any) lift due to the hole in the hood.

What would've been nice is if Kaminari had an '04+ version of their vented hood (vent in front) when I needed to replace my hood dented by snow falling from my roof. Still not an +04 version available.

Well compared to a stock intercooler scoop, it's probably not hurting you. Compared to a sealed hood, it is.

Agreed. That is probable. I don't have a feel for how much and what this mean in real-world terms.

AtomicLabMonkey 2005-08-16 02:54 PM

I doubt it's something you'd notice unless you were pushing the car 10/10ths on a track.

What about the Seibon vented hood?

I don't think this abortion would look right on a car that he's trying to stealth out.

WRC2005 hood it is then. :p I htought the Seibon hood had a forward vent on it like the Kaminari. Maybe that's the VIS I was thinking of. I dunno, I hate non-OEM looking hoods. :)

"But this one goes to 11."

If it was white, I'd offer to trade hoods :|
