Blowing through two DOA's and finding out it was 1800+ a piece to fix them convinced me to be a Ricky Racer.

--- Assuming good health --- when you are 19 years old your physiological
reaction time is about 200-400milliseconds (0.400 seconds). This time increases throughout your life so at about age 60 your time ends up around 800mS.
The engine computer talks to the power train computer (and other on board computers), continuously sharing information. Calculations and decisions are made in nanoseconds.
For discussion, let's assume a 25Mhz processor clock speed. This translates into a calculation occurring once every 40 nanoseconds (0.000000040 seconds). The processor can make 10,000,000 calculations during the 400mS reaction time for a 19 year old! You can't think and react faster than sand! (a.k.a. silicon)
While the processor(s) are constantly optimizing performance, your 0-60 times are highly influenced by fuel combustion, transmission clutch slippage and road traction.
I would suggest that a truly level playing field is man against man both driving manual transmission setups, removing a bit of the technology and evaluating skill.

the auto has very good gearing and quicker shifts, the manual has horrible gearing and is probably harder to launch. For almost any car with 300 hp+, 60mph is a relatively low speed. it's barely midway through second for most cars. this isnt the 80's anymore with 100-150 hp engines.
60 mph is too old of a bench mark. With all these modern cars being as powerfull and close 0-60, they should be looking at a new number, say, 0-75/80/100.

Al replied replied that the 4.6 time was indeed, for the stick and that he was the one who actually wrung that time out of the car.
To confirm, I then said, "So the manual is quicker?" and his response was, "Yeah, by a couple of ticks."
... and the manual is actually now very easy to launch with the new Launch Control feature that's available on the SS. Al explained during the info session yesterday that in the right setting, just get the revs up and dump the clutch... and the car takes off with optimal grip. "It will make for very consistent times", was how Al described it.
He also added that they had just found there was actually a little bit of brake drag from the Brembos, and that he would be looking forward to a little better time once that gets ironed out.
Best regardSS,
Elie

After Al announced 0-60 in 4.6 at the Summit the other night, I walked over and asked him specifically if that time was for the stick or the auto, since I was also under the impression that the auto was supposed to be faster.
Al replied replied that the 4.6 time was indeed, for the stick and that he was the one who actually wrung that time out of the car.

Launch control sounds very nice.

If they're getting mid-high 4s for the 0-60 shouldn't that be good enough to crack 12s in the quarter? I mean that is something like around a half second faster to 60 than the LS1 fourthgens, yet no quicker in the quarter? I'm thinking their quarter times are conservative...

the g8 has wheel hop above stock level HP. We'll see if they improve from it since it's essentially the same.
He's said all that stuff before too, but the car is what it is whether we forget about that stuff or have all the faith in the world. it's not going to change anything.

You're right!
I've said that stuff before........
......................and ..........uhhhmmmmmmmmmmmmmm.........
.......lemme go look.....................
Yup! I was right!!!
...and the Camaro is not 'essentially the same' as the G8 -- (unless we're talking generalities such as 'rear wheel drive' and "independent rear suspension"......

i was obviously talking about the IRS architecture since the subject was wheel hop.

I thought it was pretty clear that he was saying that you were right about what he'd said before, and he's sticking by it.
You were replying to a post that was about more than wheel hop. Anyway, I think he answered that too.
There have been advancements since the Commodore was introduced. I expect the Camaro to benefit from the same sort of updates that are in the new CTS-V. 556hp, no wheel hop.
