I posted a thread specifically asking about the A8 overheating and was told they added more cooling to deal with this issue

Is that not the case?

I'm in so cal and still haven't be able to test drive a v8 (limited supply) around me, but if the a8 automatic is similar to the one I had in my 2014 RAM R/T (also a a8, single cab truck) I doubt I will pass it up for a manual. If the temps stay ok around the track I'll also track it. I bet it will do just fine and hold its own.

2. I would like to track the next car I get. Does the A8 in the Camaro have the same overheating challenges of the C7. Someone mentioned it in this thread and I think I remember reading somewhere they had to let the Z06 A8 cool down after a few laps. Is the 6M better suited for the track?

The TR6060 is rated for a maximum 650 lb-ft of torque in a 5,291 lb vehicle.
The 8L90 is rated at 738 lb-ft of torque in a 13,200 lb vehicle.

You should be fine with either transmission. They are well suited for any type of driving/racing you want to do, and don't get pulled in by the naysayers when it comes to the overheating issue. They run them hard all day in the Nevada desert at Ron Fellows without any overheating problems, so you should be fine, too.

They added more cooling to the 2016 C7, I believe. Camaro has a bunch of cooling but I can't remember if anything is specifically for the transmission. Camaro has the advantage of not putting the transmission close to the exhaust, so I doubt we'll see the same cooling issues, but time will tell.

It's nothing I'd worry about.

Everyone who has driven one or the Vette and says there's a 1-second delay on upshifts?

In manual mode. No one has said they don't shift fast. Take a look at the video I posted of the A8 ZO6. Both the ZF and the 8L90 use the same type of design, hybrid converter setups. For some reason though the paddles are not as fast as it is in auto mode.

I'd say the A8 is a good bet, since it's the same tranny as in the Z06 that has 655 HP and torque.

That stat doesn't really mean anything at all. Simply by the way automatic transmissions operate, they are more prone to failure. Manual transmissions have very few rotating parts. An automatic transmission, by comparison, have countless rotating parts and friction materials. They are by far the most complicated system within the entire vehicle, and have one of the highest chances of failure. The reliability of an automatic transmission also wildly changes with temperature. This doesn't matter much with a manual.

There will be far more A8 failures than M6 failures due to the wild differences in design.

Yes, it is an opinion. But this is a fact:

The A8 will outsell the M6, and it will do so because of necessity. Most Americans cannot operate a clutch. If every American knew how to operate a clutch, there would be a serious reduction in A8 sales and a serious increase in M6 sales. The fact is, there are huge numbers of people that will buy an A8 and really want an M6 but never admit it, and there will be hardly any M6 drivers that would want an A8 outside of maybe once or twice at a drag strip. Many Gen 6 owners will pay an extra $1500 and get two things: an A8 and Regret.

Vehicle manufacturers are acutely aware of this "automatic transmission regret" phenomenon and that's why paddle shifters exist. They are some luke-warm sense of accomplishment.

I have been to the track several times with my 5th Gen Camaro Club. The guys with manual tranny's didn't fare too well. Most people can't shift fast enough to make up the difference. By the time you really get good your car will be worn out and beat. An Automatic for drag racing is the ticket plus you don't have to do the "Herky Jerky" around town. I had many real muscle cars with Standard Trannies and I am over them especially when I drove the A6. Bring you stick to Mooresville Dragway and we will run "Mister Know It All"!!

So just because your club members that own manuals can't drive, that makes 5th gen autos faster then 5th gen manuals?

I owned a 5th gen, for a very short amount of time since I did not enjoy it. Too heavy, not well balanced, etc, etc. But with equal drivers, stock for stock, the automatics are slower. That is a proven fact...but you can chose to think what you want.

Based on going frame by frame in this video (just after the 4:15 mark where he's shifting with the paddles), I measured the paddle delay on the C7 A8 at 633ms:

https://youtu.be/eoBrAydXK28

So a little more than a half second: I presume the Camaro will shift at the same speed so I don't believe the delay to be as much as a full second. Might seem that way but unless the Camaro paddle shifts significantly slower than the C7 with the same transmission, it's just over a half second. A decent manual driver shifting a manual can probably shift in about half that time, but given that you can factor in the delay and plan for it in most situations and the fact that you don't really have to use the paddles, I don't see the delay as being a big factor in performance comparisons between auto and manual.

Edit: did the same thing for my paddle shifting video and I get 400ms for the Challenger. Not as big a difference as I thought.

The answer is a blink of the eye. If something take longer than that (which is about 200-400ms) people can notice a delay. So if the C7 took 600+, there's why people are noticing it.

Might be faster to an "On Paper Racer" but at the track the slight difference in power looses out to the automatic so you can think what you want.
