the car won’t overheat on the street
the 1.7 supercharger does give good torque down low- but it peters out up top especially once the car is at full operating temperature.
Seats are great. Ac in the summer works well and heated in the winter is good too.
All the tech gadgetry in the dashboard is pretty worthless “in my opinion”. Unless your a tech geek that likes to full around with that sort of thing.
With all the torque down low the e-diff makes the car wiggy. Some swear by it for the track.
The car reminds me of a 2 door Cadillac.
as far as the looks of the c7z sometimes I think it looks good and sometimes it reminds me of this Seinfeld episode.

it's all relative.
it may "peter out" but that is still faster than most anything stock and many other things modded lol

Is the Callaway SC757 still available? It adds about 18 grand (or more depending on options) to the price of a Z06. I bought a used 2015 C7 Z06 3LZ M7 (without Z07), and the car can't hook up in 1st gear (65 mph) with stock power. There's isn't much margin left for more torque or power in 2nd gear (93 mph) either, so you're close to 100 mph before power mods help much. I'm a bit spoiled since I own a motorcycle, 2001 Suzuki Hayabusa, which would be the equivalent of a Z06 with 900 hp, except that it's not traction limited, even on cold tires on a cool (55 degrees or so) day, only wheelie limited in 1st gear (80 mph) (since all of the weight transfers to the rear tire, unlike Z06 which starts off with 50/50 weight distribution and a low center of mass). There are motorcycles with better power to weight ratios now, but due to wheelie limitation, 0 to 60 mph has been stuck around 2.6 to 2.7 seconds since around 2000. Again, the power to weight ratio doesn't help much until around 80 to 100 mph.

I own a 2017 Z06. It is an A8 and have absolutely zero overheating problems no matter how hard I drive it. Since you are getting the M7, that is even better for you. If you want a warranty and even more power, go with Callaway for $18k more or if you want to not have a warranty and tool on it yourself, get a used C7 Z06. You will love the car in any Z06 form no matter what others say. Personally on the street it is difficult to drive it at its full potential (unless there are zero people and cars around you on the street).

I bought a used 16 with only 3K miles on it. Did the Haltech and a ported TB. I was at Cordes in Phx in less than 6 months for upper pulley and headers. 3 months of getting use to that, came the lower pulley, flex fuel and meth kit. Also did their larger HX and an expansion tank along with the 17 SC lid. I wanted to maintain cool IATs in the AZ heat. At that point I was at 675/725 at the wheels. Moved to the Midwest and had a few tuning adjustments for better air and was at 700rwhp. Now it is going back to Cordes next month for H/C, the 2300 and other supporting mods. Hoping for 800 rwhp when all is said and done. Is it way more than I need for the street yes, but my money and that is what I want. Modding is a function of cash and time. I promise that you will be very happy with stock and the extra HP is bragging rights in most cases.

I agree getting 1LZ. The deals are on them if you are not worried about the front camera and heated and cooled seats. Other things. You get a very fast Z and just leave it stock. Or maybe change the throttle body and add the X pipe.

More than a different lid on the blower. They tilted the intercooler bricks to provide more charge cooling for the rear two cylinders because the rear two cylinders have higher combustion temps than the other 6. The tilted bricks made the taller lid necessary. The lid by itself does nothing as a number of people have already found out. The tilted bricks let the engine run longer without a drop off of peak power over a 5 or 10 minute period of wide open operation. Thus can maintain 150 mph speed in 4th over a specific distance Vs have speed slowed to 140 over the same distance.

If you were to leave the car stock without hard track abuse you would never have an overhearing issue. On the 2019 models like mine there is absolutely no issues, I ran it all day at a local track in 105F and zero issues above 100Fitjust started pulling some timing and I was down on top speeds but besides that no issues, the car now is pretty safe...
but if you start modding just for safety you should invest in cooling aids for sure, especially pushing an extra 100hp out of the car...
good luck you will love the car!

z06 is only 14k more that’s isnt much.
grand sport.
+ all the crap you will do to equal a z06...
Supercharger $8000 install $1200
tune $1000
that's $10,200 and you still have a grand sport and no warranty without the super cool carbon torque tube.

Hey there, I've owned two C6 Corvettes (one Z06 and one ZR1). I am without a Corvette right now and would like to get into another one within the next year or so. I would appreciate the new technology and features and beautiful interior of the newer C7 so I think I may have made up my mind on a C7.
My dilemma is whether to get a Grand Sport or a Z06. I've always been about getting as much horsepower as possible - even if I can't realistically use all of it on the street. But here's the thing: the car will NEVER be tracked it will be strictly a weekend cruising car on the city streets. The Z06 seems like the obvious choice still but there are a few things I am hoping you guys can clarify for me:
1) If the car is strictly street driven (in manual tranny form) are there any overheating issues or was that whole mess more for the automatics that were seeing heavy track time? Does the overheating issue go up if I start modding the car, even though it'll still only be street driven?
2) Do any of you have issues with the small 1.7L blower and does it cause you any problems if you start modding more than just an exhaust and headers?
That is my only dilemma really. I want to go heavy on the mods and get somewhere in the 750rwhp range. Is that very realistic with the Z06 or would a better option be saving the money to purchase a Grand Sport and then modding that up to 750 or so?
I've heard of quite a few Z06 owners removing the stock blower to go with a Procharger - at that point I feel the Z06 is pointless and may as well have saved the money, purchased the GS and then gone with a Procharger anyways.
Any input would be appreciated. I'm mainly just wondering if any of you who have started modding your Z06s to the area of around 750rwhp are running into overheating issues, problems with the small blower or anything else and in hind sight would have chosen the GS instead.
