This. Any thoughts on how address/mitigate?

 

I am sure the production car will be able to run a lot more than 4 laps and go into limp mode.

 

The heat soak and weight is the same issue the Nissan GTR has .a great car for 3 laps than well not so hot.I owned a GTR .A great car,but not a track car.I think the ZO6 will be much better.One thing the public doesn’t consider is the Corvette program has been racing as long as the Porsche cars.So lots of R&D and develpoment goes into there product.Dot discount the power of years of racing!

 

Very interesting....

 

The Corvette racing guys don't use a FI motor. Although ZR1's are very fast on most tracks- same issues right?

 

ALMS (and now Tudor) have very specific rules in place. You cant really compare the cars you see running there to the street versions. They actually make a LOT less HP. When I ran in GRAND-AM we ran restrictors in our Camaros that were worth 30hp.

Heat soak is a real problem for all cars.. that is why race cars, or track day cars have so many coolers! (intercooler, diff cooler, trans cooler, engine oil cooler, etc)

 

Somewhatvsimilar situation as when tracking a GT-R then. I just saw this recent video versus a Viper TA , was a bit surprised with the outcome.

 

Heat soak wasn't an issue as much as the fluid temps also due to inadequate cooling in hot temps (I have no problem in certain cooler weather for full 30 minute sessions, nor when I had a trans cooler installed).

BUT - heat soak is also a reported problem by Z06 owners now:

I'm hoping this gets addressed. Or else, the base Stingray might prove to be the more consistent (fun) track day car.

 

In the GT-R, heat soak (for engine timing/power) wasn't an issue as much as the fluid temps (except in California, where 91oct is limiting factor) - also due to inadequate cooling in hot temps (I have no problem in certain cooler weather for full 30 minute sessions, nor when I had a trans cooler installed).

I used to track my C6 Z06 hard. The car used to overheat on Circuits with lots of 1st, 2nd gear corners and medium straights. The solution was Breathless Twin Race Oil Coolers which also added 4 quarts of extra oil as well as a larger radiator. Temps were never an issue after that even on 105F track days with the AC on.

I expect aftermarket tuners will come up with cooling solutions, but i wouldn't touch a C7 Z06 for at least the first 2 years of production which is why i got an allocation on a 2016 GT3 RS already

 

Not from the looks of things. Tuners are reporting their own and customers cars cutting power within a couple of pulls on the dyno. The race video posted, the Z06 gets slower and slower with each run, and the gap gets bigger and bigger.

This car may not survive a full session with a good driver.

And notice how fast the laps from Road Atlanta lose speed. I mean the guys are losing 2 mph on the top end on the back straight in ONE lap. And even the higher speed was slow for 650 hp.

I would wait to see if they sort this out before buying one with intentions to track it. GM programmed the car to last 100k miles, and to protect itself as much as possible.

 

While I agree with the premise, this will only affect the very small market of people who track their cars. I think, from a business standpoint, the 10y/100,000mi thing is better in the long run.

 

That's why I said before buying one with intentions to track it..............

 

I know. But we are in a very small minority. Just pointing out that it may not be in GM's interest to cater to such a small crowd. However, bench racers have a strong presence on the interwebz, and make this issue never end. It could pull a few sales here and there.

 

The "heat soak" issue is that the cars that were tested were simply not broken in yet. The ECU cuts power to cool the car down. After the initial 1000 mile brake it, the car should perform like it's supposed to. I would give it some time before making full judgement on the car.
