Yep.
Sadly, retrievers (be they Golden or Flat Coated) can't keep their big traps shut.

Flats give the info away cause they're just nice that way, Goldens, because of their greed for dog toys, make you pay for it

There are certainly other avenues to try first, before developing an entire new nose design. That would cost millions in design, manufacturing tooling, crash testing, etc...

It is pretty evident that they are working on a new C7 nose though, based on the recent pics of the test mule driving around with camo'd front clip. We can make out vents next to the center grille opening, similar to the 2016 CTS-V and the upcoming 2017 ZL1 Camaro. But, we don't know if that new nose design is for a mid-model refresh C7Z06, or maybe a track purpose C7Z06, or even a ZR1. But, it shows they are working on that.

How to fix the issues with the current nose? Improve the heat transfer efficiency of the current cooling systems. Increase airflow through the radiator, increase surface area of the radiator, revise the oil cooling layout. Move more air through the engine bay, maybe with lower ducts under the bumper? Add more fluid volume to the systems, to allow them to heat up less quickly? Just random thoughts here, we'll learn soon enough.

About the 2018, is it possible some of the cooling bits we will see on the ZR1 will make their way onto the 2018 Z06? I'm thinking at the 2012 Z06 Z07 model which received ZR1's radiator and water to water oil cooler. Is there a nod here from someone that a similar pass down of parts will occur?

I really hope GM is thinking hard on how to make these new parts affordable. The supercharger lid and brick upgrade appears to be $4,500 MSRP based on Ben's thread. That's tough to swallow for maybe increasing timing advance 1 degree on track. Is the profit on these parts what GM normally gets on parts in the service department? As long as we're not getting milked for profit in an unusual manner I'm fine with paying for upgrades. That MSRP seems obnoxious to me. Most supercharger assemblies, in full with rotors and all, are worth that much.

Tony you have Corvette sources and I don't know about this? Shame on you!

Jeff's response is interesting in a number of ways. It indicates some changes coming for Z51 automatics. That means that we are definitely getting something that is not supercharger related in addition to the SC cover. I imagine this is the upgraded auto trans cooler that Jag polled about a while back.

He also doesn't list any changes coming to Z51 manual cars so perhaps they are just rerating them as good to 100F on the NA cars? If there is additional engine cooling it clearly isn't the secondary radiator as we know it today.

I also posted about a 2.3L (or larger) blower that was spotted in early production, from GM. You can bet it shows up on the ZR1/Zora. It looked identical to the current LT4 unit, but with longer internal rotors.

That's why they didn't go the full 2017 ZL1 Camaro cooling, it seems!

G fix needy

That should give a significant bump in power if it sees production! It'll need those extra side coolers in the nose.

Are 2017s coming out in Sept ?

I'm holding off buying till the cooling issues are fixed or the mid engine C8 is confirmed

Paulchristian

I tend to believe it. GM may change a blower and other internals, but to start changing body panels on the new 2017 ZO6s would be a blatant admission from GM that not only did they screwed up, but they screwed up pretty bad. They won't change panels. At this point, it is pretty obvious the exterior changes are for the ZR1.

Note the use of the term cooling "improvements." Not cooling "fix" or "remedy," etc.

E.T.D. Corvettes

Certainly. When I put my Z06 grille in my Stingray, I took note of no particular impact on fuel economy. When I used spacers with my wheels, I definitely noticed reduced fuel economy by 1-2 mpg. The spokes extend outward beyond the actual rim and definitely created drag.

The M7 Z51 and Grand Sports have received additional engine cooling which was the reason for the constraint on M7 Z51 and GS cars until this month.

5thGear

And by that you GMPP secondary radiator, correct ?

E.T.D. Corvettes

Correct

5thGear

I am a believer in the GMPP it worked well for M7 Z06

johnglenntwo

Therefore the A8 so far isn't good for 100 degrees, and essentially nothing has really changed yet!

(Z06 add SC.)

VIPERVENOM650R

We'll see. I doubt they would parade the actual production version in front of you. If there were no external changes they probably would of told us by now to help clear out the 2016s. I'm ordering a 2017 even if no EXTERNAL changes anyway. You wait for the 2018.

The_Gretz

You guys still doubt John & Jeremy...

johnglenntwo

Add the A8 is now good to a solid 86 degrees!

Classic-Chevy-Guy

Sorry, but I have to ask. Was over in the C7 section, and someone just came back from Spring Mountain and mentioned that it was 110 degrees on the track.

I would assume that this is about the hottest weather condition for any track that Corvettes are raced in.

Does the Ron Fellows school do anything to the stock Z51's or Z06's to avoid the overheating that members are experiencing? The C7 poster mentioned that they had both M7s and A8s for the school.

Just a thought and no flames please!!!!

sunsalem

This question came up before.
IIRC, someone asked the Boys at Spring Mtn. about this, but didn't get much of an answer.
