Potential Z06 buyer with cooling question
Sorry to bring up an often hotly contested and sometimes argued issue. I've done lots of reading on the cooling issue already, but my intended use for the car doesn't fall neatly into either the road-only or track-only crowd.
My intended use for the Z06 (with manual transmission) is mostly road use, but also some hard canyon driving (with lots of tight twisties) lasting anywhere from 15-30 minutes. In your experiences, would I be susceptible to engine or transmission overheating during my canyon runs?
Thanks for your input.

You'll be arrested or killed long before you have any overheating issue with your stated usage.

You will have no problem what so ever. I pushed my 2016 Z06 for 25 minutes in 88F ambient shifting at red line on the track with no issues and also 20 minutes hard canyon runs in 95F ambient also with no issues. M7 is an awesome choice. I had GMPP secondary radiator that really helps on the track. I don't think you will need it for canyon drives.

Worst case scenario - add the auxiliary radiator and that is all it will take.

My C7Z actually runs cooler than my C6Z did. Spirited street driving, similar to what you describe, is what I do. You will love it with the M7

In my M7 I've done more than 20 mins of very hard driving in 90F temps and all I saw was around 220-225F coolant temps. I didn't monitor the engine oil temp. So I don't think you'll have any issues either.

Although I am sure this particular OP meant no harm, I had to laugh at this one.

I have a 15Z with the GMPP Secondary Radiator added. I haven't come close to overheating the engine. I can't see how canyon driving gets anywhere near as hard as track driving. There is no way you can push a car on the highway as hard as you can on a track. There are just too many blind spots, dangerous things along the road and other vehicles to be safe trying go as fast as you can on a track. If you can't see around a corner on the highway there is no way you can go into it at high speed like you can on a track with a flagger standing at corner entry telling you the track is clear ahead of you. At tracks across the country there are plenty of somewhat blind turns where cars approach at speeds in excess of 150 mph braking to 90 to 95 mph and if there wasn't a flagger standing at corner entry nobody would have the cajones to drive in there at near triple digit speeds not knowing if the track is clear or not.
You won't overheat an M7 during canyon driving.

I love track days and don't get to do enough of them. But I street drive my 'track' cars. With 99% of my miles being street miles, I'm loving the daylights out of my Z. If I overheat on track I'll either dial things back and still have fun or consider one of the two aftermarket cooling options (or whatever GM musters if it works).

If not clear where your canyon road driving is but if you are over 10,000 ft altitude and in hot weather you may have a problem. Turbocharged and supercharged engines lose about 1.5 percent of their power for every 1,000 feet of altitude and can overheat.

2 weeks ago at Spring Mountain, I drove a manual transmission Z06 in 90-100° temps for 2 days. On one session, I saw 277° oil temp and 260° coolant temp. All it did was shut down the A/C. And, yes, I was driving it as hard as possible in 3rd and 4th gear.

Spring Mountain Motorsports is in Nevada and not even 3,000 ft elevation. If the OP drives his car in the Mount Evans Scenic Byway in Colorado he can hit 14,000 ft elevation which could give him problems in hot weather.
