I don't know it just looks awkward Jim, Not centered or something with the placement of the oem opening. Maybe the whole plastic behind the hood should be madeup so the scoop could be moved to the P.S. abit more to make less crooked.
The GD has a cleaner and better placement for a scoop.

Actually, that design get's the air moving in the right direction before it hits the opening in the cowl, thereby getting air farther towards the driver's side where the filter is. I like the general shape of it, and the forward facing design.

 

Definitely makes for more of a challenge.

With the idea of the scoop cantilevered toward the center, another thing that could be done is to place a short rib across the bottom, separating the scoop section from where the hole is. This way water could accumulate in the scoop section without much flowing to the opening in the cowl.
I think the shape could be made much more pleasing with a little work too.

 

I def like the rounded one that is more front facing alot better but perhaps lower and more streamlined looking? would this have to be removed to open the hood? also it seems like it is moving more and more left, how hard would it be to prototype something on the center plastic section rather than the tiny one, that way it can be fully front facing and be directed right onto the intake area? just some thoughts, great work tho!

 

can't wait to see this concoction.

 

I'll have the next sample finished up in a couple days. I think I'll just send the part out for testing and not post any pics off the car since these are hard to imagine what it will look like installed. So beangrower you should have it in around a week.

 

any updates on this?

 

I sent the latest out about a week ago. Hopefully we'll have a report soon.

 

sorry for the late reply. i just got it this morning. will get better pics when sun is out and i finish work.


as far as the backing part, the fitment is great (had to hold it down cuz no tabs)


here's top view:

will get more pics later on today.

 

Hmmmm....first thought is that the latest pix suck, but this can be easily remedied.

Regarding the scoop...unfortunately I think this project is moving in the wrong direction. I liked the way the previous scoop was predominantly nestled within the plastic cowl. Now, it's awkwardly suspended out and over the plastic cowl with a gap, albeit small, under it. I'd prefer something simple and sleek rather than something so elaborate. I really don't want any gaps up around my cowl...that just screams "aftermarket add-on."

Again, I think the previous designs are more pleasing to look at...despite the aforementioned minor quirks.

 

no offense... but that thing turned into an eye sore. I would rather see a scoop that would blend and would look like it's part of the entire abs-shroud cover.

IMO... more lines would blend that all those curves.

 

sorry...these pics "suck" too...but at least they're in the daylight.

im pretty sure jim didn't intend to have the gap there, its just he doesn't have a car to work on so he has to make adjustments per pictures i give him...but first has to be the overall idea of the scoop form. To me, this third variation is a step in the right direction. Its front facing and probably a little better in preventing rain to enter the engine ba y, especially for us diy short rams.

 

Looks good.

 

It looks much better in daylight with the hood down. I'd like to see some pictures taken from the passenger side with a real camera to see that awkward gap/forward profile.

Is this a cell phone camera? Do you have a real camera? No offense, but I really can't make out any detail from these images...if you're gonna post up images so we can offer input on the design then you should at least use a real camera. Just sayin...

 

Honestly, I think that looks really cool. Much better on the visual design. Yes, it looks "trick" but at the same time, it also looks like a fancy highly engineered scoop, like something you might find made out of carbon fiber in japan that people spend $600 on.

As long as it's sturdy, and won't break off when I try and insert a towel underneath it when drying the car, then I might get one. I think functionally, this might even work better than something closer to the opening due the increased volume of air entering the scoop and then being diverted out the opening towards the driver's side where the intake is rather than shooting it straight down.

edit: Upon second though, I'm no engineer and can't really tell if one design is superior to another. It would seem that the larger the volume of the scoop before it enters the engine bay would have to do with how much pressure can be created though.

 

Maybe a thin rubber gasket under the scoop would eliminate the gap and provide cushion to prevent cracking/squeaking

 

i really don't think the gap is suppose to be there. correct me if im wrong rogue. I think he's trying to get the overall design first off before taking care of the fitment issues. im sure he'd easily make adjustments to close the gap if he had a ge8 nearby to work on. right now he's going off of crappy cellphone pics.

 

The way the scoop is slightly elevated and the upper part extended forward looks to have been well thought out in regards to functional efficiency.... It should catch more of the air being vectored at an increased velocity by the angle of the hood.

 

True. Also, without seeing the wind tunnel tests, we're not even sure what kind of pressure there is on this part of the vehicle in the first place. Regardless, I don't think any kind of a design like this could hurt. Now that the air is cooling down outside, this, like weight, is a huge asset for our little cars with their limited tuning options and performance. I'm enjoying the coolest air outside yet since I got the car, and it is a lot more responsive.

 

I've read this three times and it still doesn't make sense. LOL. It is well known that the rear of the hood (especially at the angle with the windshield) is a low pressure area. Leading edges (i.e. front bumper, top of windshield) are the most functional areas to place a duct or air inlet because these are high pressure areas. Obviously, this is not an option in our case (i.e. cowl scoop). The next best step is to increase the surface area of the duct/inlet in contact with the wind.

Elementary drawing:


In order to increase surface area in contact with the jet streams coming across the hood, the inlet needs to be angled forward...i.e. you want the angle between the air and the inlet to be 90 degrees, anything more or less decreases the surface area of the inlet in contact with the jet streams:
