UTVOL06

I saw this posted by Talon90 from one of the NCM Bash slide shows. I bet a Z51 equipped Manual will be able to hit sub 4second 0-60mph times since the 4.1seconds is based on a best average rather than the best time achieved.

2005-2007 Mn6 manual is rated at 4.3 seconds and the A6 was 4.5seconds to 60mph. Was the Mn6 1/4 mile 12.8seconds@113mph for 05-07 models?

All I can say is look out Tech Section because the best 1/4 mile times for stock C6 are about to be overtaken.

AFVETTE

This is what GM published and claimed for the 01/02 C5 Z06:

"The Z06 will continue to be outfitted with the unique six-speed manual transmission for 2002. It will enable skilled drivers to achieve 0-60 mph times of 3.9 seconds and to cover a quarter mile in 12.4 seconds at 116mph. By comparison, the 2001 powertrain combination achieved 0-60 mph in 4.0 seconds and the quarter mile in 12.6 seconds at 114 mph."

I was hoping 430/436 HP would finally better the C5 Z06. I wonder if TM and or the slightly narrower run flats are killing the "off line" performance of the C6??

Well I would hope with a new more powerfull motor the 08's will overtake the stock 05-07 times. Otherwise it would be pretty sad to not run better with 30-36hp more.

We already have some stock C6's achieving 12.2s in the 1/4 mile with a 2008 we should see 12.0 or possibly dare I say 11.9s? So I don't think the old article from GM on the 2002 C5 Z06 was wrong. The Skilled driver quote refers to a best 0-60mph time achieved. Which for the 2005-07 C6 mn6 Z51 was 4.1seconds with an avg best of 4.3.

If the avg. best for the 2008 C6 Mn6 Z51 is 4.1 we should see skilled drivers hit 3.9seconds as well.

2006 Dodge srt-10 Viper:Does this mean the 2008 Mn6 Z51 will be equal to an 06 Viper now?

Look at the picture. It is hard to accelerate (or stop, or turn) with all 4 wheels off the ground. Bottom line, hp does no good if you can't get it to the ground.

Hey shopdog if you order the GE Turbofan option with rear thrusters this is no longer the case.

AFVETTE

You mean a Corvette can't accelerate in a staright line w/o getting airborne?? I knew that occured at some point on the Ring but that was in excess of 180MPH.

Slow Vette

no, according to that corvette video we all get when we buy our cars new...its 12.5 or 12.6(can't remember the ET) @115 mph

harmsway22

I think the 2005 -07 (manual) was rated at 12.7 @113.0 mph and 12.9 (auto) @ 109 mph. So the extras 30/36 HP looks to have taken .2 to .3 off of the 1/4 mile time. Hopefully the 6 speed auot for 08 will be @ 12.6

and the 0-60mph times have dropped by 0.2 tenths as well. I know the new Mn6 Tr-6060 tranny should provide better times too with faster, smoother shifting, and other upgrades.

I think we're looking at the 08' Mn6 Z51 being on par with a 2006 Viper?

Marina Blue

Those are great numbers. The '08 is .2 seconds and 2 mph faster than '05 to '07 cars and equals the '04 Z06 at Nurburgring. Otherwise it is 3 seconds faster at the ring than the '06 car was. All in all, this is a great accomplishment. However, I am still very satisfied with the performance of my '06 Z51 (4.1 sec to 60 and 12.5 @ 115 for the quarter-mile) vs the '08 Vette (4.1 sec. to 60 and 12.4 @ 117 for the quarter-mile). for both cars

LS WON

Faster than a 427 or 454 C-3 big block.

EggrollXpress61

I thought Automatic times were usually faster than MN6 times w/ corvettes because its hard to shift as fast the computer? Is this not true?

LS1LT1

As you already know, published manufacturer or magazine times are one thing...the real world is another.
Torque management was a problem on the 400hp/400tq cars, I can only imagine what it will be on the 430hp/424tq cars running through the same drivetrain that GM is trying to protect from shattering.
And all this new power on the same tires too...traction?
Those few extra pounds (if the published weights are in fact real) added to the 2008 won't help matters either.

Slow Vette

i don't think so, because the Viper is very capable of 120 mph trap speeds, but it may be able to match the ET though. right now its all speculation

LS1LT1

Well, yes and no.
On average the automatics will likely win in a best out of 10 straight line racing scenario but that's mostly due to the skill levels of the drivers IMO.
A truly well driven manual should take the automatic all else (raceweight, track/air conditions etc.) being equal and the manuals will almost always hit a higher trap speed.

UTVOL06

No, the A6 auto has always laged by about 0.2 tenths slower than the Mn6 version. If a manual is driven by a skilled driver it will always beat the A6. Now when a DSG or auto clutch comes out by gm or something similar watch out Manuals. Until then Automatics require a torque convertor and there is more lose of power in the drivetrain over an Mn6.

But if you have an unskilled driver in an Mn6 and the same in an A6...the A6 will likely win. Also it's easier to make mistakes in a manual. Like not shifting at the optimal RPM through each gear.

Slow Vette

unless its a F1 gearbox...

LS1LT1

True but we're talking traditional automatics and Corvettes here.
