308 GTS Side Scoop Differences?

Hi,
We are currently working on a 1979 308GTS and have noticed that the cut out in the side scoop appears to be different from pictures of other similar aged cars we can find. The opening on the car we have here seems to extend a lot further forward than other cars we've seen.

Both sides are identical.

Does anyone else have a car with a similar opening extended forward like this?

Cheers
Jon

Never seen anything like it. Weird. The doors sagging a bit too, as I'm sure you've noticed. Gorgeous color though.

 

Missing the pninfarina badge too. Any body filler in the area?

 

I have never seen anything like that and can’t imagine it is original.

I noticed that the door locks are flush to the body. That too is not original on a 308. Something is strange with the history of this car.

 

Also, the louver looks likes it is bent.

 

You're also missing the ducts, the scoops aren't going to work without the ducts. What kind of oil temps are you seeing?

 

Pretty sure the door looks were recessed into the doors late 1981

Only modifications I've seen to the side scoops are the German cars with the mesh covering the hole, but I'm not sure if they had to modify the bodywork to fit them.

 

No, the mesh piece fits the standard scoop hole.

 

Someone did that in a body shop.

 

I mean... I know that oil coolers have been mounted differently over the course of the car's existence and would like to think that the shape of the scoop would be associated in some way, but damn! What you have seems pretty extreme. Maybe rust formed there and instead of fixing it, they simply reshaped it?

 

Door rocks in our cars "went flush" at some point, before the Door handle change of the 328....

I have received replacement "308 doors" that had the flush lock indent, in fact no one noticed and put it back together that way...

Those scoops OH My GAWD but its a nice look...
As both scoops "mate to air ducting" I'd like to know exactly what / how/ when they though they were doing ..

The original venting of the engine compartment is marginal but increasing it would only make the eventual fire BURN faster!!!!
Halon,,,,,needs Halon...

 

It is artfully done but they should have finished the ducting to the new revised opening......

 

Thanks for that data point....I always wondered.....

So based on the original poster saying the car is a 1979, and recessed locks introduced in 1981, perhaps the car was a prior builder/repairable(?). Aftermarket wheels common on many rebuilt theft recovery cars. What's curious to me is what appears to be a flatter aluminum plate inside the modified LH scoop... I would have expected a nice view of the top of the LH fuel cell. Possible powertrain mod with extended cut scoop opening for additional (random) cooling?

 

I took my car out tonight for a short drive, thinking of this.......the OEM flow of our 308s was "bottom to top" of the engine bay as there was a sheet metal scoop to make it flow from the bottom...

Then they realized the rear roof made a "dead zone" pocket of backwash as the air circled off the roof, leading to our common aero foil spoiler, to break that back wash and encourage flow, rearward...

IMO only "pumping air in" from the sides, without ducting (as original for carbs airbox, and oil cooler on driver's side (US), just kind of makes a dog's dinner out of engine bay airflow..

Anyone else's take, or am I on point here??

 

The "scoops" have a defined purpose, the right side is cold air induction to the intake and the left side is a pressure duct to the oil cooler. They aren't "vents"

 

It looks normal for me, could you be more precise on what you think it is wrong? Could you post a picture of the opening to compare?
The car has some aluminum side door, which is not period correct for a 1979 car. Could you tell us the VIN?

 

Sorry but the side scoops do not a normal entry into the engine.

 

Sorry you are right, I was focusing on the door side louver....

 

which is even not an aluminum louver, my mistake, forget about my previous posts...

 

Well...I don't know if my thoughts have any value, but...for what they are worth...I am NOT an aerodynamicist, nor do I have any qualification in fluid dynamics, but I do know, through my interest in Formula One, aviation, etc...that an efficient scoop is very difficult to design (we all know about the NACA ducts, etc...).
I always had some doubt about the efficiency of the Dino and 308 door scoops: they probably catch "some" air, but their shape is probably more due to aesthetical considerations than strict efficiency. Therefore, I honestly doubt that enlarging the back of the duct could help to catch more air; it was probably done for another purpose (?)

I've always wondered what the pressure in the scoops was like at speed. Is is positive or negative? I've suspected that air does get sucked into left scoop because the engine bay is low pressure, not because the scoop entry is high pressure. But maybe it doesn't matter.
