I kind of torn between a 19 Z06 or a 19 GS, but leaning towards the Z06.

I'v read that a ton of owners still experience reduced power mode, even when the car was not beat on too hard, or very long.

I can't seem to find any reports of the 19's experiencing reduced power mode, so i'm looking for knowledge here. Does anyone know if it has improved in the 19 year model?

Thanks all.

From the reviews I have read, not much has changed. I know a lot of Z owners that do not have the overheating issues. Besides, that's something that I think can be managed with some cooling mods and tuning.

There is also the option of supercharging a GS for a little over $5k. Then again, for 5k you can add some nice cooling mods and 100 whp to a Z06. Lastly, the GS is still not a Z06...

I thought about just buying a new one myself but instead, decided to get a used '16 Z with 6k miles, a big step up from my C7 Z51. In the end, your roaring down the road in a Z06!!! Good luck...

insurance is more, overall maintenance will be higher as well. but you pay to play. and as for the overheating crisis? much hype vs reality. A8 cars of all years driven at 9/10ths or irresponsibly, will do it. not many around here could get the car to do it due to driving car to limits more than not understanding how to use the torque of this engine vs high rpm (like a C6Z LS7).

The M7 cars with Aux radiator do not experience overheating in any conditions as i've read on here. real world? who knows

And if anyone tells you any C7Z overheats in spirited driving? they're either full of it or are driving like a moron, OR there's a mechanical problem with the car.

Are you going to track your car? I have never tracked my car (2016 Z06) and have never come close to overheating. It's a wonderful car and I have had no end of enjoyment from it. If you want this car for a daily driver, buy the Z06. You won't be sorry.

I track my car often and hard. No I am not a pro. I generally am at the front of the intermediate group and have ran with advanced as well. My car is a 2016 Z07 manual. The only mod is the gm secondary cooler which cost me about 900 installed and doesn't effect the warranty. I also got the GM 100 octane tune. And the PS cooler mod from gm less than100 bucks. I don't drive this car on the street. I trailer it to Mid Ohio, NMC Motorsports Park, Gingerman, Grattan, Autobahn. Andy Pilgrim has run this car, hard. No limp mode, no reduced power, now do I think you could go ***** out for an hour straight in this car? Probably not, but thats ok, cause at that level, you run out of gas between 40 and 45 mins...

IF you are talking automatic that is a whole different ballgame. If you are seriously going to track car you have to short shift it with the paddles which is fine because this car has so much torque down low. Most guys short shift around 5 to 5.5k. If I had an auto and was going to hard core track it, I would take it to LG Motorsports.

If you are talking just on the street or even drag strip, you have zero worries.

AVETTE

PS starting with 2017 the secondary cooler already comes with the manual cars (autos can't use it do to location) so you wouldn't have the extra expense I had. GM high octane tune helps with the computer pulling timing when it gets hot. I use Torco or Boostane and race gas to keep me from losing any power when it is almost 100 deg out during the summer.

Yes I plan on it, but not very often, and not until I put at least 3 to 5 months on the car to get used to it.

tbran6

M7 for sure. And thank you for the awesome input.

Their is a technical bulletin out for reduced power mode on 17 Z06's and 18's that you only need if you are tracking the car. It is a software update and corrects the problem and all is good.

Always Red Dave

Now get your Z06!

tbran6

Awesome, thank you.

I am in the same situation- do I really need 200 more hp for what I am doing with car vs a GS- I guess it is nice to have- but just the other day had a sheriff follow me in my GT350 then at light run my plate on his computer.
Where I live in Florida speed limit is 45 everywhere so.....
Tuff issue I am dealing with even more so since I want a vert.

If you're genuinely torn, get the Z or you'll hate yourself, unless you plan to do more than 2-3 genuine road course track events per summer.

The Z can still be driven at the track and will NEVER give you a problem on the street.

I have a 2015 and no issues. Don't confuse the problems our hardcore track guys have had with anything you'll experience unless you plan to join their ranks, in which case you should get the GS M7. But in all other cases, the Z (and I recommend the A8) and you'll thank me.

Outlaw Joe

If yours is going to be a daily driver and then I would get the automatic but be careful they have problems with the torque converter (and I recommend the M7) and you'll thank me.

A8s have some issues with over heating on the track. M7s don't. On the street none of them have an over heating issue. Those are the facts. Sure a few may have an issue on the street but some Stingray owners have had over heating on the street as well. The general gist of things is you can pretty much beat the hell out of an M7 and it will do fine and there are plenty of forum members doing that and setting individual lap records. The M7 Z06 is a beast on track.

I have been running my 15 Z06/Z07 M7 for two seasons at places like Watkins Glen and VIR in ambient temps in the low 90s without coming close to over heating. There are others that are pushing Jim Mero's test times at VIR. The GS is a nice car but if you want to be on track with the monster that passes just about everything then you want the Z06.

Here is something to think about. I have been having an intermittent high rpm misfire on cylinder #8 when on track. Sometimes it lasts all day sometimes it starts in the middle of a 20 minute session and quits 5 laps later. I can tell when it starts misfiring and when it stops misfiring but the person riding in the right seat can't feel a thing since the car is still one of the fastest on the track. Top speed will drop from 154 to 145 but the car still pulls hard off corners and gets through corners faster than my previous Corvettes so when it comes to lap times it is still running damned fine lap times. The car with the misfire is amazing and without it the car is astounding.

I have never had a reduced power problem with my last two Z06's, 16' and 17' no matter what the temp is outside, no matter how hard I drive the car. I did have no steering several times, but that was from a bad Bosch steering rack that was replaced on my 17', there was a problem where some bad steering racks got into cars. The GS is fun, the Z06 IMO just more fun, some is good, more is better

davepl

Not in the Z. He's asking about he Z. Your concerns might apply to the GS, however (if it has the weaker TC and clutch packs of the Stingray), another reason to opt for the A8Z.

badhabit_wb

I'd get the z. I have a 15 z and I've also added the secondary radiator, brake cooling, ps cooling, and 100 octane tune. I usually shift before redline as well. That will keep you out of trouble temp wise. Your oil temp will run much higher than coolant and if it gets up pretty good I just change the oil after the track day. This time of year it won't happen.In the summer it probably will.

HOCKEY

I am in same thoughts as was going for GS but I think it will be the Z06 I order in summer.

tbran6

The secondary radiator is a good addition. I understand it came standard on the 2017 up.
