All great info until Chevy marketing un does it and adds more confusion with their description of the ducts on Chevrolet.com.

 

I recall either making a similar comment or that someone else had mentioned the same thing previously--yes, "Marketing" does not equate to any understanding of engineering. The average tire-kicker isn't likely to pay much attention--has to be frustrating for the effort to be put in to make changes like this and then see them bastardized by people who don't have a clue....

 

Any pics of those ducts?

Based on what I've read, I doubt the exit will provide any useful purpose

 

I have a parts illustration--can scan and send for now, still trying to figure out how to post it (and not get into trouble with GM)

I doubt the exit will provide any useful purpose

There has to be some silver lining in the change--so I'm giving the benefit of the doubt to the engineers, but, like was done with the Z/28 when it was introduced, and the C7 Corvette, I'd like to see something that more graphically demonstrates the results of the change(s), not that I'm at all skeptical--but yours is a fair "question"....what useful purpose has resulted?

That said, other than the cosmetics, have you noted any benefits from the Camaro hood vent panel on your SS?

 

Aren't these vents essentially the same as what was done on the front of the BMW 1M fascia, again for aero purposes?
Not an engineer but from what I remember the explanation was that it decreases drag from the wheel well.

 

correct.

 

Without test data, we can't say if there is a net improvement or reduction in brake cooling. Less turbulence around and within the wheel well may reduce brake cooling and not improve it. Unless shown otherwise, I'm of the opinion that any effect on brake thermodynamics is likely quite small and unimportant for a street car.

 

There was a previous discussion regarding the front bumper air duct venting and if it was functional. There is a picture floating around the net showing the duct behind the bumper. Is this the one Navy?


There is also a picture of some wind tunnel testing demonstrating that it does indeed pass through. Whether or not it is functional as a BRAKE cooling duct, remains to be seen but unlikely.

The picture in your post is not the part used in the 2016 front fascia, and it is quite apparent that any brake cooling benefit is strictly incidental--the air flow path is nowhere near the brakes, if you consider that serious brake cooling efforts would be designed to direct air toward the eye of the rotor, on the inboard side.

current CTS-V brake air flow directors:

 

Maybe contact Monash University Engineering dept for their findings: http://eng.monash.edu/mechanical/about/holden.html
'An element of the facelifted Commodore’s design that was important to Holden was the adoption of functional bonnet scoops and air intakes in the front fascia. These were developed by Holden’s own engineers, with support from Monash University, allowing the use of its wind tunnel'

'Mr. Holmes also described the challenges in introducing the new 6.2-litre engine and pointed to the revised design of the car as a key factor in enhancing many of the cars performance attributes.

“One of the considerations in utilising the bigger engine is heat management and airflow. We spent time at Monash University to develop aerodynamic performance and engaged heavily with our design team to make sure we didn’t miss a thing,” said Mr. Holmes

All VFII sports models receive a new front fascia complete with a larger grille, facilitating improved cooling airflow. Additionally fascia ducts allow for improved aerodynamic performance by reducing the size of the wake off the front corner of the vehicle.

VFII V8 sports models receive a further engine cooling aide in hood vents that allow the release of hot air directly out of the engine bay whilst simultaneously giving the car a more aggressive appearance. The hood vents have also been engineered to effectively redirect water away from critical electrical components in the engine bay.

Holden’s Design Director, Richard Ferlazzo, said VFII’s design changes complimented the engineering work done under the hood and ensured the car continued to stand out on the road.'
