Does GM have any plan to sell a cooling pack in the future for the C7 chassis? Is it even a possibility, and if so, what would it look like?

Background
The limitations of the radiator and related parts that help the car stabilize oil and water/coolant temperature are easily reached when the C7 Z06 is driven aggressively (such as on a track at an HPDE event). There are now many reports from owners overheating the cars in 80 degree weather or even in 70 degree weather. This limitation of the car as sold will be exacerbated in the coming summer months. Many media outlets have reported overheating. This includes every occurrence when Motor Trend tested the C7 Z06 and during daily driving the C7 Stingray by Edmunds. See here:
http://www.edmunds.com/chevrolet/cor...tain-road.html

The commonly displayed overheating message is "Engine Overheating, A/C has been turned off, please idle engine." Coolant temperatures in particular quickly approach 257 degrees which prompt the computer to issue a warning in the center display.

Other manufacturers offer such an optional package to effectively cool the car. See for example the new Shelby GT350 Track Pack is described as follows: "optional with the Track Pack, an engine oil cooler and a transmission cooler."

Certainly seems important to me. Should be the next question asked of Tadge.

This question is of vital importance and needs to be the next asked/answered.

What we; well me, are asking for is a GM engineered and designed increased capacity radiator with an integrated secondary engine oil cooler, or a separate engine oil cooler exposed to maximal airflow along with the more efficient radiator. This upgrade would be made available to current and future owners for purchase and installation at their local Chevy dealership so that warranty coverage would be maintained. I totally understand that this upgrade might not be available as an additional option during the build process since it may well alter emissions results, etc.

The car was sold as the most track capable Vette ever and to my mind it is in every way, except for the unacceptable overheating issues that should not occur during an HPDE event.

with all the above. This needs to be addressed.

I stand with the men above. Lets get out the vote on this one.

+1 to this question.

I track my C7 Z51 manual Stingray and it runs very hot (even w/upgraded oil). Not hot enough for warning lights to go on, but hot enough to make me nervous. My buddy has the C7 Z06 manual and has had warning lights go on on the track from engine overheating. This shouldn't be happening in a car marketed as "track ready"

CONMAX

a recurring issue and not acceptable for a track oriented car. GM needs to develop a track package that can be retrofit into all C7's experiencing overheating on the track.

I thought the Z51 was the "track" pack. Its deficiencies should be corrected and track performance limit spec's be added to the track preparation document.

I agree. Car def need better cooling.

This needs to be the next question The car was sold as the most track capable car, when I'm told/sold this it means I can run a HPDE session without overheating. GM needs to come out with a package.

For a car marketed as the "most track capable Corvette ever" it should be able to make it through a hot summer (100 degree ambient) HPDE session (30 minutes) being driven hard by an instructor level driver.

GM needs to develop a track cooling package. Something owners can buy that will retain their warranty.

It is sad, my friend has a dedicated 370z track car. When his was down, he tracked his wifes bone stock z4 35idrive. and once his cayenne diesel. Hes never run into the cooling issues on those non track cars.

RapidC84B

In GM's defense... none of those cars have 650 horse to cool or can achieve the speeds of the C7 Z06.

We deserve a response.

Oil temp reached over 300 degrees according to dash gauge (need to confirm in Toolbox data) during session at Sear Point on Wednesday.

70 degree ambient
A8 Aero 1 on Supersports
Driven in "D" auto mode
2:00 laps (not fast for this car. I am afraid of walls and tire barriers and don't have much seat time at Sears)

Transmission clearly is programmed for "maximum attack". It needs a "Calm the f$%k down" mode for track days where you are not attempting to set a record for a car magazine with no regard to the lifespan of the car. The sweeper immediately following the esses had the car hold about 6000 RPM for a ridiculous amount of time. No human would keep car at that level.

I suspect that this shift programming is designed to beat TA at Laguna.

No way it could finish a lap of the ring without overheating in D. No way.

Shifting manually? Hopefully that is the answer.

Camaro 1LE next to me in paddock hit max of 235 degrees in same session. He was a much better and experienced driver. Much quicker times.
