ZO6 overheating issues ***MEGA Merge***

i have a Z07 with an A8 because i felt it would be the most capable combination on the track as well as the street.
i will agree that most of us that own this combo don't track it a significant percentage of the time. not even 5% or 1% in my case. this still translates to 2 outings at willow springs in the 5 months that i have had the car.
the first time in april, it was fine, great handling, no overheating, ran for about 2 30 minute sessions. performance better than my well prepped C6Z51. Temps were in the low 70's.
the next time, earlier this month in june, it was close to 100 before noon. the car overheated within the first 5 minutes of running, with CEL on and reduced power. i was using manual mode and taking it fairly easy. the car will definitely not handle hot track days, even for a short time.
it is great on the street. the carbon brakes stop very well. they don't require any warm up like some people on the forum say. i think they are even a little too powerful when cold and you need to be careful that someone behind can't stop as fast.
too bad that the cooling system isn't up to the rest of car's capabilities.

What a lame excuse.The car needs to be recalled.And what's lamer is they had a full year to fix it and they haven't for 16 model.

It should do a 20 minute track session good or bad driver. I'm dissapointed so many people have problems. Was at a track today with 90 + temps. C6 and all the Porsches did fine.

They will not make any changes to "fix" the issue because they have already sold 8400 of them and don't need to. Sales are great. It will take crappy sales for them to want to address their issues and I don't see that happening. The car is just too cheap for them to not sell a ton.
It did however make me cancel my CTS-V order. One overheating LT4 is enough for me.

Overheating on the track? Here's my solution.
For the 1% ho drive their zo6 as it was advertised on the track and have overheating problems. Get together with over zo6 car owners at your tracks and let's post the results on YouTube. I'm sure it will get noticed by Gm then. The forum is in denial. The same car owners are bashing others for taking their cars to tracks. It's been a year and nothing getting done about it.

Got to love all the GM apologist who come to the rescue every time one of these threads popup. GM needs to recall these cars and fix the overheating issue people are having. Plain and simple. This is unacceptable especially after GM swept the c6zo6 head issues under the rug. Looks like they are doing the same to C7ZO6 owners. Most track capable Corvette my ***.

The overheating horse is alive and well.
No amount of bizarre posts from people who don't actually track their cars will change that fact.
I have no idea what motivates these folks.
I don't drag race. If someone posted something about an issue related to drag racing, it would be really odd for me to chime in with, "I don't drag race, so I not only don't care about your problem, but I think you should not complain about it."
I have never experienced this with other car forums. Is this a "Corvette thing"? Denial and lack of solidarity? GM must get a kick out of it.

Cars prepped scrupulously according to the manual.
Tadge says that there is a problem. It is weird that you take a position based upon lack of direct experience, and that is contrary to what the manufacturer says about the car.
That is a whole lot of denial.

And I will bet many people who will not track, would like to know for image and pride they have a car that does not quickly overheat. People not tracking on this forum are still dying to know the Ring time. Still bought because of the performance claims and the image that comes with that...
Most Porsche, Ferrari or etc.... will not track, but I don't heare anyone of those MFGs accepting cars that overheat easily on tracks in what is normal summer time temps...
Yes, even if you don't track, it is a problem on resale and it does kill living vicariously with those that are trying to track in the same car, or when you are bragging about your car to your buddy and he says its a great car for the first 5 minutes! Remember that people bought cars in the old days of NASCAR, because how they tracked, even though they had no plans to ever track a car.
I don't play pro football either, does not mean I want to own season tickets to a team that only plays the first qtr and then goes down the toilet for the next 3 qtrs!
And they will fix it in a couple of years, which means every one will be looking for the cars with the fix,,, not yours....
I don't recall until the Ask Tadge response that the design was for 85 degrees or even less in the A8 in any literature. And on an 85 degree day, the temp at a track can be 10 degrees hotter... wiping out half the country for half the year... and winter wiping out the other half of the year.
And it is still JUNE... and by the way its in the 110s in Montana and Idaho , even Washington and Oregon.... so no summer racing and no winter driving.
Get this fixed... for those that track and for those that would like to think their car could be one of the ones on a track.
Regards,
Viper as in a Scarab Viper...

In the dyno test article that I wrote, where I monitored external temps and IAT1 and IAT2 values on subsequent dyno pulls, the blower itself did not appear to be the cause of any heat issues. It is a tiny blower, but GM did a good job on the cooling system of the unit.
As for the Procharger, you also haven't had any of those making hard laps at the road course, which is the only place the C7Z is shown to overheat. I would assume it will have the same issues.
This is purely a radiator size/efficiency issue, coupled with the tiny grille opening. Fix those two, and this issue should go away. That is also the feedback I got from a couple GM engineers (Corvette team), when I asked them about the overheat issues. The car was designed for the 95% of buyers that do not track, and those buyers will be happy with it.
