this is (off track overheat vote) Race U's experience with overheating. Not performance related.
Here is "Entrenched" another off track overheat vote. I found nothing in any prior post related to any overheating issue and was pretty open about how much he paid, all modifications etc etc. i would suspect this one to be mod related or a mistake. easy enough to check yourselves by clicking on the name and viewing all posts by a member. here is "CDJnight" (another off track overheat) couldn't find anything related to an overheat but did inquire about a cat heat shield in a thread related to the cat heat shield topic? here is "Big Lebowski" another off track vote and then no update from here So idk what outcome was or if it was a one time thing. self admitted driven on hotter days harder and no issue. IMO this is how this gets blown out of proportion which is the reason I've focused on the off track right now. eventually i'll check some of the on track guys out but many of them i recognize the screen name from other Z06 threads and trust those votes..

FYREANT

So Higgs poll Isn't good enough?

23/C8Z

change it to public poll to keep it honest. he underestimated the hatred some have for this car.

let the results speak for themselves here. i will not run down every name but anyone casting an untrue vote will not be hidden from other members now at least.

thegeneral101

I've run mine pretty hard and never had an overheating situation down in Miami.

BEZ06

I've tracked my M7 quite a bit and have never overheated.

.

Questar

My A8 will overheat when tracked in full auto mode.

23/C8Z

when i get home I'll list the new voters.

bredle

In over 32,000 pleasurable miles, my '15 C7Z has never overheated.

djnice

I like these poles, but often they are not perfect. For example, on the track I have run very close to overheating so I backed off and let things cool down before running more hard laps. I have never owned a street car that I could run full out, lap after lap, without having to let it cool down.

I voted no, but in my opinion keeping temps below limp mode is better for engine longevity. I prefer oil temps no higher than 260F. When it gets over 260 it is too hot even though it hasn't overheated. If the pole said does your Z06 run too hot, I would vote yes.

BladeZ06

Voted - No

Daily driven A8 Z06 in Fl 100+ heat. Driven hard no overheat.

Spring Mountain driving school - 2 days in 95+ heat running in the fastest group. Set fastest time for the group. A8 Z06 running in manual mode. No overheat.

davepl

Votes yes on track because it happened once on track. This poll doesn't differentiate, of course, whether it happened to you once on a hot day or every day.

NJZ06

Voted Yes, April 2016 - happened on a track during the Ron Fellows class in their Spring Mountain, Auto, Z06. Happened on the last session of the 2nd day, I was chasing my instructor and my car overheated on the back straight, throttle cut out and dash lit up like a xmas tree. Was short shifting the car at 5k the entire time, but we were in the fastest group of drivers. My car was the only car to overheat all weekend.

Mad Dog 24

Again..... NO overheat or limp yes i track the sheet out of it too. Agree with OP public is a better way to determine negative imposters.

Higgs Boson

so far we are still in the same percentage range as my poll.....who is checking validity on the responses now that we have public poll?

Bill Dearborn

What do you consider as very close to overheating? The only way to judge something is for it to actually happen. There are too many opinions of close to over heating. Somebody else may have a definition 15 degrees lower than you. Running it till it actually over heats won't kill the engine. If it did then any time somebody had the common occurrences of a hose failing or a water pump locking up they would ruin the engine and that just doesn't happen.

Most people I have learned from want to keep it below 260. Yes, that is my opinion and personal preference for my car.

sunsalem

Although I would have thought there would have been fewer votes/reports of overheating, the poll results (so far) aren't particularly surprising.
IMO, 14% is too GD high.
Sadly, GM isn't going to do a thing about the problem.

illmac77

Over heat opinion and limp mode due over heat are two different things...


voted no, driven just as hard as on a track in the middle summer on Texas roads for extended periods of time. 17' M7.

Questar

To clarify my earlier post... I have overheated (ie. exceeded 263 degrees F water temp and car went into limp mode) on two occasions. Both were during road course track days. Ambient temps were not high but car was being operated in “auto” mode. At the time oil temps were climbing and had reached well into 290’s... but limp mode activated on water temp before oil temp maxed to trigger point.

I have also triggered limp mode at Spring Mountain... high ambient temp, in paddle mode but not short shifting. Happened once... did not reoccur after I adjusted driving to shift at under 6,000 (@5,500).

The car runs hot, especially on track. Even with short shifting in paddle mode, I can avoid limp mode overheat BUT, temps average 235-255 water and 275-285 oil. Both are higher than I’d like to see (sustained) but that’s how the Z06 runs from my experience.

fmcokc

No you didn't. If you did you would be dead or in jail.

You did not drive WOT for 50+% of the time for 15-20 minutes.

You cannot simulate track conditions that your car experiences on the road unless you are a total sociopath.
