What part about my statement is inaccurate? All cars suffer heat soak - Period. Super charged cars suffer even more than naturally aspirated cars as you should know. Of course a better radiator like the LG Motorsports Super Cool Radiator (And other brands) will help as it will help all cars. But show me the guys with C6 Z06's that have the cooling issues that the C7 Z06 does (Stock vs stock)? Where is this data?
That is what I was discussing as well as SBC and others. The C6 Z06 does not have a cooling problem - Period. It has had other issues that are well documented, but cooling it does not.

Chevy was warned....
A very reliable source has told me that Pratt & Miller tested the Z06 for Chevy and in a documented report they told Chevy that the cooling system was inadequate for the car.
Chevy ignored it.....
Don't shoot the messenger...

They made a corporate decision that there are not enough "racers" who buy the Z06 for it to affect their bottom line.
Too many people posing while busting along at 35 MPH own this car

Ha! you got that right, but thats about the the only benefit I can think of. After reading the C&D article, along with all the other reviews which involved certian failures along with a long list of my own, I cannot see what GM's thought process is other than, " our demographic does not drive the cars hard enough to cause any problems". My dealer is trying to tell me that my problems are because I " race" the car. I am flattered, but I try to go out on the track and learn as much as I can and impove until it over heats but that sure as hell is not racing it. So the take away is: car looks really bad ***, and on the street is a terror and can out run most on the interstate and other street venues. So its a brawler, but get it into the ring and it will throw in the towel after a few rounds. What a cluster fu*k.

Considering the safety risk of overheating, would a class action lawsuit be in order? There are customers of other marques that have put pressure on respective manufacturers to address important issues.
I'm the last guy in the world that would would advice lawyering up but the code of silence is disheartening. This is especially in comparison to Porsche that admitted and resolved the issues corporately.
Considering the documented magazine reports of overheating, does one wait for GM to release a statement admitting the issue before end of year?
There is no excuse for bad engineering. If there are engineering and financial constraints, it only benefits the manufacturer to be upfront from the getgo.
I leave it to you guys to decide.

It seems adding additional radiator capacity is not helping all that much. The problem seems to be around air flow. Given that the front end design is not going to change all that much, perhaps the better aftermarket solution would be to increase air flow via more powerful fans. It would seem the draw through fans are about maxed out (cannot draw significant vacuum with a fan) but perhaps an aftermarket solution that added significantly powered pusher fans in front of the radiator could be engineered to over come the air flow deficiency of the front end design?

1. As you said, the demographic is a very old man that keeps the car as a throphy behind glass.
2. The few old men that can drive proper and do so, are also the type of repeat buyers that have put up with GM's insufficient cooling for a decade or more and they are ready to do so until their breath is gone. I can name at least half a dozen of these guys that post here every day. They drive up to the track, they short shift the **** out of it, they return to the pits in half a session, and go home early. They log on to corvetteforum and they report what a great time they had.
GM knows 1,2 and made a conscious decision to save the money on developing an up to par for 2015 cooling system. What we have is a devoted user base, and a manufacturer that takes advantage of it. GM is new business, has been since I've been born, they'll lay a railroad track over you carcas for a nickel. Nothing wrong with that either, business is business, but these old school GM lovers have much to suffer for it. They are the last of their kind, the rest of America started waking up in the '80s.

Aftermarket can do quite a bit for the M7, but where are you going to put another core for the A8 guys? I've been following how long the aftermarket has been working on the M7 oil cooler. At this rate the A8 guys will get an aftermarket fix when the C8 comes out.
Passive airflow is better for the track than the fans. The airflow limitation is binding, no way to overengineer that one. You have to start drilling holes in the front bumper or grab air from the bottom of the car. No other way.

Two things GM took into account:
1. As you said, the demographic is a very old man that keeps the car as a throphy behind glass.
2.

Just about every car in Motor Trend's last face off had a more extensive cooling system, some had half the power and double the cooling capacity. When you see the PDR for some of our guys, the coolant goes up to 250* in two minutes. No chance to fix that with a slightly larger radiator that has minimal airflow.

I hope you realize that in some of your posts, the above being one, you come across as an arrogant tool.
I expect that I am one of the "old men" whom you're referring to. I drive the car to the race track, run it for the full session by short shifting, have an incredible time and have been the fastest car in my run groups thus far.
Good luck to you and hope to see you at the track some day; just please give me a point by when you've overheated the car. Again.

Funny how us old men that keep our cars behind glass then bring them out to the track and flog them. What was the glass for then? I think SBC_and_a_stick is confused.
Mine doesn't overheat unless the AC is on and it's over 85F.
You know what? In this 214 page thread there's still no concrete solution. That leads me to believe there's no concrete problem to solve, or someone would have done it instead of whining incessantly.
Can't Ron Davis build a better radiator that still fits? Has anyone added an auxiliary oil cooler?
Nah, because whining and moaning is more fun, less work, and you can do it all winter.

I noticed that Harley Davidson got a class action suit on some of their newer touring bikes. Now that group is dedicated to the brand, but few are standing up for the motor company and telling the guys who have problems that they are whiners and compainers. And that IS a group of old men. They want it right, period. We should too and I am happy to join in any lawsuit concerning the cooling issues in my ZO7. I still have a hard time believing I could over heat engine coolant and power steering driving at my level, short track or long track. Over 88 degrees, forget it. I only planned on going out 4-5 times a year. Sign me up if anyone wants to pursue it, but what a PITA thats going to be. Still I don't like getting screwed and the silent majority might consider that they are too.

No heating issue here. Running 80% water with water wetter.
But GM is working on upgraded radiators.. Heard there is fix for heating issue for time being.. But not sure how well it works

Z06 or Z07? M7 or A8.
I am starting a database to collect all the data we can to see if this is just a few cars and what set up is most affected.
Thx,
