Factory Aero mods that you may find interesting.
 
I saw a very rare car last night on the road and posted it on a hotrod site I visit. Then we started talking about other "production" aero mods that manufacturers have done and sold them to the public to allow them to qualify for NASCAR. Some interesting things to show you what can be done to make a car slicker in the wind. It's called "free horsepower". You loose NOTHING, only gain. Unlike a blower which takes horse power to run, or other mods to the motor which have a give and take, aerodynamics are FREE, they sacrifice nothing.

This is the car I saw last night. I don't believe I have ever seen one on the road, a 1987 Monte Carlo Aero coupe.

One with a "little" history. :)

And a standard Monte Carlo.....

One of my favorites, a 1969 Talladega Torino Check out the extended nose and the REAR bumper narrowed and put on the front! Remember, these cars are not one off mods done by hotrodders, they were done by the manufacturers, maybe 1500 or 2000 were made and sold to the general public so it could qualify as a "production car" as per NASCAR rules.

Here is the most famous of these cars, the Dodge Daytona Or in this case a Plymouth "Super bird". Basically the same car. These you will see once in a while, I believe they sell repro parts to make them so some you see will be fakes.

The Mercury Cyclone spoiler was pretty cool.

Very interesting stuff, and HISTORY being NASCAR has went down the crapper they will NEVER be as interesting as creative, as this. Now they are all the same and I have no reason what so ever to watch it.

One I have posted before is the Droop Snoot Vauxhalls (GM)

Hey Cool, the Vauxhalls I believe was sold here under the "Opel" name.

This nose is basically what should be done with virtually every Volvo made until recently. And a belly pan. And fairings for all wheels. Pizza pan wheel covers. Skirts on back wheel wells. Rear diffuser would not hurt either, nor would removal of roof rack.

My bro has a ~20 year old Volvo wagon that gets ~32 mpg on the highway @ ~75 mph, loaded to the gunwales with heavy crap. I bet he'd get ~40 with such mods.

This 1966 mustang has a similar 'superbird" look.....
I am a pretty avid Ford Mustang guy and I have only seen this kit once...

Yep - Chevy Chevette = Vauxhall Chevette = Opel Kadett = Isuzu Something or other = Holden something or other. World cars at their finest / worst :D

Arragonis 08-23-2010 06:45 AM

One more - how about a whole rebody ?

FSO (Poland) is one of those companies that took old FIAT 124/125 models of the 1960s to make as their own - in the style of Lada, amongst others.

Like Lada they kept then in production for ages eventually rebodying them into the Caro.

The Zuki Kizashi, on the Bonneville salts.

Big air dam, side mirrors deleted, fences over the roof , mooneyes ...

One of the video's here shows how the mooneyes were fitted to the Kizashi's steel wheels.

An easily overlooked part of the Daytona/Superbird aero pkg. The rear window has been pushed out to the body lines.

I forgot about the window! And I have a friend with one of those cars, how stupid of me. Yeah, it was a little more than simple bolt on items on that one.

MARTINSR 08-23-2010 02:25 PM

That Pontiac is even better than the Monte Carlo!

lunarhighway 08-23-2010 05:51 PM

not as glamorous as the cars above but nevertheless a very serious factory aeromod was that of the opel kadett e, standard vs GSI

where the standard car had a 0.32Cd wich was quite spectacular for a small hatch in the 80's
but the gsi lowered this to 0.30 with the addition of small hood vents a rear spoiler a different bumpers and moldings in front of the rear tires

it's remarkable that such subtle changes brought about such a great improvement

Hello -

In a post I can't find, aerohead said that the original S-Series coupe would be a good platform for aero-stuff. It's also light, so it would be good for electrics. It was even a mule for the GM EV-1. Here is a side view :

http://ecomodder.com/forum/member-cf...coupe-side.jpg

You can see the very-close-to-covered wheels, clean flowing lines, and the swoopy nose.

Here is the front view :

http://ecomodder.com/forum/member-cf...pe-front-1.jpg

The small front radiator opening is typical of a lot of late 1980's aero-designs. What I hadn't noticed before is what appear to be front wheel deflectors on each side. I am positive that between those deflectors would be a black plastic deflector to deflect air onto the radiator.

3dplane 08-23-2010 09:49 PM

@cfg83! I got one of these sitting in the yard. Well, mine has the spoiler on the deck lid ( I guess that's the SC2 )

What appears to be a radiator opening ( Behind front plate in your picture )
is actually blocked off,fake opening.

You are right between the two deflectors there is a scoop type air intake.
( on mine it's broke off but at the edges I can see what it used to look like when it was there )

Unfortunately no title for it so I can't drive this little aero car : (

cfg83 08-23-2010 10:21 PM

3dplane -

That's neat! The fake opening makes it more aero than I thought. Too bad about the title.

CarloSW2

3dplane 08-23-2010 10:36 PM

Also interesting to note the little cup shaped ridges directly below the headlamps. They are probably some kind of turbulators for the time when the lights are opened up so the open lamps are not cutting into clean airflow,rather
ride behind a bubble of higher pressure air? I'm just guessing.
Of course it's a compromise because when the lamps are closed,the airflow could be cleaner without them.

I'm yet to see another car made with only a bottom air scoop and no other openings on front. It sure looks like they paid attention when designing the SC.

The other major change was the grill - swapped for the cheap one-piece big opening version for the small slit on the GSi / GTE. That version of the Astra / Kadett was good though - a kind of magic sweet spot of early 80s lightness, and mid-80s aero before weight became a serious issue for most cars.

JasonG 11-06-2010 05:30 PM

My S series would get 40 MPG on the highway.

Funny, 1970s they knew about droopy noses with small grills and sloping rears.
What happened in 40 years?

I have always been intriqued by thre reverse scop over the fender.
I wonder if there is excess air building up in the fender well from the front nose??

botsapper 11-06-2010 10:53 PM

Want retro? What was good then, must be still good today.
HPP, a company that makes Superbird body style conversions. Looks so much like movie 'Cars', Dinoco's Strip Weathers aka The King!!
Also want a 2011 Firebird? See their 2010 SEMA offerings.

My reading indicates that they had a problem with interference of some kind in the race cars when they were lowered and running on the high banking of one of the test tracks. So they added that scoop to the base car, and started telling people it was to let the air out of the wheel wells.

I don't know how true the account I was reading actually was though...

This image seems to show very full wheel wells at the front, could also suggest the scoops remove air for coolling of the brakes.

Except, do NASCAR cars use brakes except on pit stops ? :confused:

botsapper 11-08-2010 02:20 PM

Confirmed. NASCAR-configured Daytonas and Superbirds cutout the hood tops and capped them with top flare covers. The aggressive deep bank racing bottoms out the available suspension travel, needing that extra tire clearance. The street cars just homologated those vestigial parts, for reproduction detail.
