Cutting Vents in a Rear Valence Options

[silver six]

Eventually I want to install my 914-6 rear valence back onto my car. I think it makes the whole car look super cool (see green car below). But it is my understanding that the valence captures a lot of heat, causing things in your rear trunk to melt and running your engine/tranny hotter than necessary. That was, apparently, why Porsche switched to the short skirt valences after 1970 or so. But you know, I still want to put the old-school full-valence on my 6.

So here's what I am thinking: Maybe I can cut vertical vents in the valence, and provide cooling that way while still giving the car, overall, a full valence look. I got this idea from VW Squarebacks, and more recently, from the oval vents in the rear valence that RUF installs on its 911 conversions (see yellow 911 photo below). In the alternative, circular holes about 3/4 to 1 inch in diameter set in a row, or maybe even two rows, offset at vertical angles, (sort of like the olympic rings, but not overlapping) might look cool.

So the thing is, I was sort of wondering how this would look. And I also noticed that some of the people on this board appear to be fairly astute at photoshop. And if it wasn't too much of a hassle I thought I would just ask if someone might try cutting a few holes in the rear valence of the green car (below) with photoshop in order to see what this would look like. I know it's sort of a tall favor so I certainly understand if people have better things to do, but I sure would appreciate it.

Yellow 911 just like the silver/blue one above.

Cool, green 914 with full valence.

holes

slots

I like slots better.

These are really crudely done.

[jonwatts]

I like the slots too, but I'd put more of them all the way across (even on the other side of the exhaust hole).

Thanks for a good idea I can steal! (IMG:style_emoticons/default/smile.gif)

big holes

[Porsche Rescue]

I vote for slots, all the way across, or at least 6 inches more in each direction.

[Aaron Cox]

yeah...slots look really cool! make more of them on the outers and on the edges....(it's amazing what paint and photoshop can do) (IMG:style_emoticons/default/mueba.gif) :sweet:

[seanery]

I like the slots best, BUT, how would one go about making them?
I could do the big holes really easily with a hole saw and could have
a good clean edge with a little filing. But what would be a good, clean
way to do the slots?

[djm914-6]

Best way to do slots is to drill holes at the top and bottom then used a saw to cut the straight lines between them.

I like the slotted look just like in the picture posted above. BTW, How dod you get the dog to stay in the same place for all those pictures? (IMG:style_emoticons/default/blink.gif)

He's not real. It's a stuffed animal I can pose in different ways.
See pic below.

I like the slotted look, too. But I think that slots running the entire width might be a bit much.

Here's a newbie question: Aside from decoration - what purpose does the rear valance serve? Cooling, aerodynamics?

Damned if I know (IMG:style_emoticons/default/confused24.gif) ....aesthetics, would be my guess.
It also catches grunge thrown off the rear tires....what purpose that serves, I dunno.

On another note.
Rusty:
Are you going to sit out these latest....unpleasentries?
It would seem fair due to your recent deployments.....but I know that "fair" really doesn't enter into the equation.

I'm still in the US, but that could change at any time.

Things are kind of up in the air for me. I am trying to make a career change (within the Army, rather than leaving). Those actions are pending, and I'd rather not jinx it by running my mouth. If my request gets approved, I'll have to move, but to go to school.

Sorry, I know that's kind of vague. But I need to be for both operational security, and to not jinx something cool. (IMG:style_emoticons/default/smile.gif)

Seanery,

Very nicely done. That gives me a really good idea what the end result will look like. I think the big holes look pretty good, but the vertical vents look just a little cooler. The vertical lines work well with the 914's rectangular look.

Thanks much for the photoshop work! Nice job.

Olav,

is going to cut his rear valance and ad stainless mesh like a GT3RS factory race car uses for the radiator openings. The slots would look cool, but the mesh is easier to install and bends nicely to carry the round shape of the 6 valance.

I'm just getting the pieces together.

Actually, I was going to use the grill material found on the engine lid cover as the mesh material for the valance.

[Zeke]

Once before, on a valance on a different type of car, I used a router and a guide to cut multiple slots.

I don't think the slots of holes let as much air out as you think. Look at the back of a NASCAR stock car. The ass end is as high as they will let them, even with the fuel cell hanging down like it does.

Slots do look cool, though. (IMG:style_emoticons/default/cool.gif)

Brad and Olav,

Interesting modification. I would be very interested to see how it turns out.
