BigNastyZO7

I'm at Carlisle and met a worker from thr plant driving a 17 ZO6 (no names sorry) and I seen the 17 Zo6 in person that he was driving...

Facts:

1) No hood changes besides thinner interior hood pad to clear taller Supercharger lid.

2) Cooling bricks/blocks are same size BUT using different angles to cool rear cylinders (which seemed to be the problem of cars going into Limp mode)

3) No Bumber Changes

4) only on manual cars they will use the intercooler for the automatic as engine coolant instead, along with previous radiator

I have pics of car (Hood closed tho sorry guys not my call) I will try to post on ph or when I get back home on Sunday.

Wow what a nothing burger. Thanks for the info.

Go to the GM tent, a black rose 17 sits with the hood open. Larger cover is the only obvious change visually.

I REALLY need confirmation on a freakin cooling fix. I ordered another A8 because of the posts saying GM had improved the cooling to 100 degrees ambient. GM needs to speak up. May have to settle for the M7? We were assured by our connected CF members we would know something this weekend. NOT HAPPY. Any firm date when '17 Z production starts?

GSpeed

There are two separate issues with these cars, like we have stated from the get-go:

De rating due to blower temps or pump cavitation/pump shut down

engine over temp due to cooling system inadequacy.

It appears GM has focused more on the loss of power, than the cooling on track. The M7 has a problem that has been "fixed" where the A8 is still problematic.

Unfortunately, par for the course.

If you ordered another A8 and planning to track it then you are making a mistake. The good thing it's not too late for you to change the order to M7.

GM official word was A8 is meant for one hot lap followed by a cool down lap. Customers planning to track the car should go with manual. They never made any other statements to say A8 is good for road course so if you have problems with 2017 A8 on the track then it's on you. Don't take forum opinions as facts and later scream that GM lied to you.
My advice, go with manual

Before we all decide that GM is abandoning the automatics, know that they're still working on solutions specifically for the A8. They wanted to get the manual solution out and in the hands of enthusiasts while they continue to figure out what to do with the auto.

Please be careful with statements such as "par for the course", et al. You're not as knowledgeable about the situation as you think you are.

So does that mean they plan to have a solution in place for the '17 A8 cars and not just the M7 stuff that was revealed this weekend?

...or is the ultimate solution the A10? I would also like to know if there is going to be an A8 solution for the 2017s or if this is it.

I'm going back and forth with the M7/A8 debate as I only plan to track my Z06 2-3 times per year. However, don't want to limit my track time to one hot lap at a time with an A8.

jvp

I don't know, and, honestly, I don't think they know yet.

Well, I am now glad I went with a procharger versus waiting for the "better hood". Poor engine bay heat circulation is the number one issue IMHO. Even if the "new" SC is cooler, over time, with track use having the heat trapped in the engine bay - it will likely over-heat.

5thGear

The problem with A8 as explained by GM is its close ratio transmission that keeps the rpms high and therefore generating more engine heat. Therefore A10 would make the problem worse. Not to mention fitting two more gears in the same tight space will cause less room for transmission fluid. I don't see how A10 is the solution. It would be a bigger problem at the track. If anything they should consider A7.
Since there is no clear direction on A8 and most likely it will never run cooler than M7, I would listen to GM and get M7.
I had A8 Z51 and M7 Z06. Both were fun to drive but I know prefer M7.

I thought we learned at the bash that the A10 wouldn't fit. The A10 is also delayed for the ZL1 so if that were the announcement it would mean big delays for automatic buyers.

MSG C5

The argument for the M7 certainly got stronger based on the information shared today. Good news on the higher intercooler and the engineering behind that solution however.

Funny that the C7 generation Z06 was the first to offer both a coupe with a removable roof and a convertible, both with an automatic transmission. People flocked to these options which expanded the market, however for the true track rats, the M7 (fixed roof) may be the best solution and maybe what the future ZR1 will offer.

Plus, this now gives me a legitimate excuse to tell the wife why I chose the M7, plus it saves me $3K over the A8!

For those who saw/heard Harlan and other GM staff say the A10 will not fit in the C7 and doubted it, on a road trip in rural Wyoming, I ran into a lead employee who works for the manufacturing company that has the contract with GM to produce 7,500,000 A10's over time (and yes, many are also going to brand X). He confirmed that not only is the A10 2" longer than the A8, but this it is to possible to not modify it to reduce its longer length and retain its 10 gears.

In either car, the engine RPM is controllable by the driver.
AFAIK, a driver can maintain any RPM he wishes...

That's your first mistake...never give a woman a "legitimate excuse."
Otherwise, there isn't room for a man's natural ability of creative truths.

lordofwar

like I said buy the 2016 leftovers for huge money off.you will be happier now and down the road when you go to trade it.

GSpeed

Actually, we know a lot more than you'd like to give us credit for. But that's ok and par for the course

Having logged more track miles than any aftermarket
Company with this car, short of GM, we know exactly what's going on, and what Necessary steps need to be taken.

It's ok that they didn't fix the auto, it puts food on our families tables.

LSs1Power

Are you thinking about including the new SC hat in your kit? Also how much would that help and if you need to change your kit design?

I'm asking because this could lead into a lower cost kit made by you and if swapping the oil coolers location with the intercooler makes more sense now? Meaning two oil coolers on the sides and one intercooler in the middle?

redzone

I have a lot of respect for what your company has done to address the cooling issues of the Z06. I really do. But coming into a thread that has nothing to do with your company, other than perceived competition, to slam GM does nothing to further your image.
