This is straight from a guy who has owned and drag raced both cars. Your not going to make an educated guess after a 10 min test drive.

A high 120mph trapping car will ***-whoop a low 120mph trapping car.
Nothing subjective about that.

Hmm, so heads, headers, programming, airbox, and I can hang with a new Viper.... Gotcha!

2.73 Vette

Well I totaly disagree with you UNIT...

do all c6 Z06's trap high 120's...

Thats total BS....

Only one mag got any were near high 120's and that was a 127...

Kinda strange how that mag got 127 but every other mag got 120-124 mph...

Almost every owner around the country has also trapped 120-124 mph ( with most around 122)

Kinda like the mag that trapped 123.8 in the new Viper when every other mag trapped 118-121 mph....

Almost every owner in the country has trapped 118-122 mph ( with the average around 119 mph)

With good drivers at a good track the C6Z06 will run a 11.8 at 123 mph with the viper running a 12.0 at 120 mph...

These super freaky C6Z06's running 11.5 at 127.0 or freaky Vipers running 11.7 at 123.8 do not represent the norm what so ever....


But 11.8 at 123 for the Z ad 12.0 at 120 mph for the srt 10 are good representations...

This is not a war between a 120 mph trapping viper and a 127 mph trapping vette...

If your gonna quote the fastest time for the C6Z06 from a mag at 11.5 at 127.0 then please do the same for the Viper with it's 11.7 at 123.8...


Or even better use the 11.8 at 123 that the average C6z06 driver can get with good driving and the 12.0 at 120 mph that the average SRT 10 driver can get with good driving...

there is only a 2 tenth andf 3 mph differance between these two cars


Road and track got a 12.2 at 121 mph from the C6Z06 and a 12.1 at 120 mph for the Viper....

At their track with their drivers the Viper had the quicker ET....

Motor trend got a 12.0 at 124 mph from a C6Z06 in their april 2006 issue squaring against a porshe 911...

Then in a later issue they tested a Viper coupe to a 12.0 at 121.3 mph...

Im not trying to twist any ones arm....But just stating the truth...

And various mags have gotten 11.7-11.9 From the Viper....

Dont compare the fastest time ever of 11.5 at 127 for the vette against the slowest 12.3 at 118 mph you canfind for the viper..

compare apples to apples

300bhp/ton

2.73 Vette = Line limit of 5 lines, character limit of 150

SouthFL.02.SS

Certain guys from this site used to run 11.9 @ 119 mph in stock C5 Z06's on drag radials if I recall. Average C6 Z06 Vette drivers of America and mags must suck @ driving, as street tires should MPH no worse than drag radials. If an LS7 can't click through the traps at mid/high 120's in stock form, then what's all the hype about?

2.73 Vette

No no and no....

The average C5Z05 dynoes 350 rwhp and will run a 12.5 at 115 mph..

Yea you get some strong ones that dyno 360 rwhp and get around 12.3 at 117 mph....

But for every factory freak you have dynoing 360 rwhp and running 12.3 at 117 mph,

you have 10 more dynoing 345 rwhp and running 12.6 at 114 mph


Here on LS1 tech we will have the tendancy to always use are best numbers for each vehicle that is from Chevy....

Only on LS1 tech do we beleave that all LS1 mn6 Fbodys dyno 315 rwhp bone stock and can run 12.9 at 109 the way they came from the factory...

Only on LS1 tech do we beleave that all 2002 C5Z06's dyno 360 rwhp bone stock and can run 11.9 at 119 mph the way they came from the factory....

Only on LS1 tech do we beleave all C6 Z06's dyno 460 rwhp and can run 11.5 at 127 mph the way they came from the factory...


Whats funny is that if you go to a dodge site or 350Z site they will base their judgements on what theve seen at the drag strip....And at their dyno shops.

They will say that F body's run 13.5 at 105 on average and dyno 300 rwhp.

They will say that c5Z06's run 12.5 at 115 mph and dyno 350 rwhp on average.

They will say that C6Z06's run 11.8 at 123 mph and dyno 440 rwhp on average.

But then thy'll say that their beloved SRT8 can run 12.6 at 112 mph...Or their beloved 3350Z can run 13.5 at 104 mph ( based on the fact that one factory freak SRT8 or freaky 350Z has accomplished these feats) so since one has done it they dismiss the fact that almost eveyone else is ATLEASTE 3-5 tenths away from those numbers and that all SRT8's and 350Z's can do it...


We are exactly the same.....We say that stock Fbody's are 12 second cars cas 1 out of a thousand may possibly do it on the day when theirs a negative DA of 2000???????

To me a SRT8 is a low to mid 13 second car...A 350 Z is a extremely high 13 to low 14 second car...

But try asking the owners what they think...

So I still stand by my opinion that a SRT 10 Viper will run dead even with a C6Z06 from a 70 mph roll with equal drivers...

It will lose the 1/4 mile due to 180 pounds and softer out of the hole gearing...0-60 mph is were it looses....

Look at the new 500 HP Shelby as a perfect example....

It has 500 HP compared to a C5Z06's 405 HP.....Yet it has a slower 0-60 time of 4.5 for the shelby verses 4.2 for theC5Z06....

Then the C5Z06 can cross the 1320 at 12.4 and 116 mph......Compared to the 500HP Shelbys 12.7 at 116 mph....

Why is the shelby slower?????? Because it weighs 3900 pounds vrs the C5Z06's 3100 pounds....That 800 pound differance makes it hard for the Shelby to get up and go off the line... But once it dose get to 60 mph in 4.5 seconds it acellerates harder in a shorter distance than the C5Z06 to still trapp at 116 mph.

But make no mistake......If a stock C5Z06 and a stock 500 hp Shelby were to goat it from a 70 mph roll the shelby would beat the C5Z06...

The fact that it's 800 pounds heavier means much much less at 70 mph and the fact that it has a 100 more rwhp means a lot lot more at this roll race speed.


Now put the Shelby against the srt 10 Viper and C6Z06 in the 1/4 mile....

12.7 at 116 mph and 0-60 in 4.5 seconds for the Shelby
11.7 at 123 mph and 0-60 in 3.7 seconds for the Viper
11.5 at 127 mph and 0-60 in 3.5 seconds for the C6Z06

( all the best figures I could find from main stream mags for each car)

Each car has aprox. 500 HP..

But these battles are being one in lost in the first 60 mph at the drag strip...

The C6Z06 weighing in at 31xx pounds and having agressive 1/4 mile gearing jumps out fast to 60 in 3.5 seconds....

The Viper wich has a low weight of 33xx pounds also jumps out nearly as fast but the highway gearing effects it's performance to a 0-60 of 3.7 seconds...

The Shelby is almost handicapped from a stand still due to it's 39xx pounds. Despite having the same power as the two above and having gearing equal to the C6Z06's...The weight is just to much to start in motion resulting in a 0-60 of 4.5 seconds....

So yea it seems like the Shelby would just get creamed in a roll race with the C6Z06 with the Viper being walked as well...

But at 70 mph and ABOVE with the car already in motion the weight dosent mean nearly as much as it did in the launch of the 1/4 mile....Agressive gearing for getting out of the hole also looses some of it's merit..

But arodynamics and actual rwhp and rwt now take over....Especially at over 100 mph ( wich should come up EXTREMELY quicky in any of these cars from a 70 mph punch)

The C6Z06 dose NOT have a .28 drag coefficiency like the base model c6's.

IT HAS .34...WICH IS AROUND THE SAME AS THE .39 FOR THE VIPER ( THE SHELBYS NUMBERS WERE NOT RELEASED BY FORD)..

While looking for these numbers I came across the Motor trend issue of Jun 2006 ( Target Z06)

Here they got a stock C6Z06 to run a 12.0 at 123.5 mph.........Two inches above that they state that they ran a stock SRT 10 Viper to a 12.0 at 121.9 mph...

Both running 12.0....With the C6z06 trapping 1.6 mph higher...Yea thats defiently a high 120 car racing a low 120's car....

That sounds exactly like road and tracks 12.1 at 120 for the Viper and 12.2 at 121 for the C6z06 to me...

But back to the Shelby..viper and C6Z06 all punching it from a 70 mph roll....Yes at those speeds the Shelby will be walked by the Z06 and Viper....

It's arodynamics look to be in the mid 40's to low 50's and even at roll speeds..600-800 pounds cant simply be dismissed...

But the viper has similar arodynamics and a weight differance of only 180 pounds...So the differance is very minimal ( once again the vipers tourque of 525 crank vrs 475 crank makes up for this small drag and weight differance....)

Bringing these cars to equal in a roll race ( but not the 1/4 mile were the Z06 IS FASTER)

Yes, yes and yes.
11.9 @ 119 on drag radials, stock. We all know who it was.

We here at ls1tech can drive our cars.

Heck, when I used to suck at driving, I used to trap 118mph on a cam only (at the time), daily driven, stock suspension-ed boat of an Fbod that you see in my sig. No skinnies, no weight reduction- and I still used to get crap for being a crap driver around these parts.

SouthFL.02.SS

Only on ls1tech does a newb ls1 fbod driver [me, a few years ago] run a 13.9 in his new 2002 SS first time out (same as your average magazine time) and work his way down to a 13.1 on the same setup after reading how to do so from this here site's drag racing forum.

CTSVSL65AMG

This is all pointless, the cars are very close in performance, no one is going to spank the other. And for the guy that keeps saying I owned both and raced both....big deal. I used to race an s2000 and it was faster than aorund the track than my viper and faster in straight line than my LS6 thats putting 400 to the ground, whats your point? I drove both extensivly and they are both freaking awsome, the extra torque in the viper probably make it feel faster than it was, but we are splitting hairs...

I STILL THINK ITS FUNNY THAT EVERYONE IS COMPARING THE C6 Z, WHEN THE ORIGINAL POST WAS ABOUT A C5 Z!

I think this is a good summarry...

Gen II GTS Vs. C5 Z....edge to Viper.
Gen III Coupe Vs. C6 Z...edge to Vette.

02ZOh6

2.73, there's no sense in regurgitating magazine times. Even though most of them point to the Z as being the faster car. We've all seen vids of these cars going at it on the street and the Z definately looks to be the quicker car. Fadi, WHO OWNED AND RACED BOTH CARS in case you may have missed his post has confirmed this. Get over it, the Z is lighter, makes the same power and the Viper's gearing sucks.

02ZOh6

No, your post is pointless. How can you dismiss someone who has owned and run both cars and gives you legitimate feedback? IMO his posts carry much more weight. You, my friend are the one with blinders on.
How does you road racing an S2000 (Which I guarantee is not stock if it's faster than your CTS in a straight line) have anything to do with this thread?

CTSVSL65AMG

Were his cars modded? Which one? How much? Did he race them at the same time? Was a he a better racer in the vipe rot vette, where did he race. Is he biased........

My point was too many variables. Anywho, like I said...they are very close, and the was the original point.

CTSVSL65AMG

Your right, his comments do carry some weight. I never once said the Viper was faster, I just said it won't get owned by the C6 Z, at that statment stands. Will it loose head to head, probably by a small margin. But that was never the discussion was it?

AOC

Since your reponse is so precise, I have to ask, how many samplings did you have in order to come to above conclusion? Did you go around the USA and tallied up all the C5Z's dyno and track numbers in order to come up with those numbers?

What scientific method did you employ in order to be that specific. Just wondering.

Fadi

Like I said, I had both cars and I am giving you non biased opinions. They are close, if the driver in the Viper is a good driver and the driver in the Z06 is an average driver. With two good drivers, the Viper is going to fall back quickly.

Based on the driving expereinces in both cars, I can say that the Viper had better brakes, better seats (more supportive) and a better stereo system. The Z06 has much more comfort, better acceleration, better handling, better mpg, and is just a much better overall car. This is just my opinion after having both cars.

Fadi

Oh, and regards to a C5 Z06 and a Gen II Viper, I can give some accurate feedback here also.

I raced my 340 rwhp Z06 vs. my buddies Gen II RT/10 Viper on a constant basis back when we had the cars. The races ALWAYS had the same exact outcome. Up to 100 it is practically dead even. Past 10 mph (Very end of third gear/right when I shift into 4th) that is when the Viper will walk away from the C5 Z06 everytime.

02ZOh6

No you didn't say the Viper was faster. You said their 0-60's and 1/4 times were mirror images. I'm not going to try and define what a 'walk' is or what 'owned' entails with respect to these two cars. The bottom line is the C6Z will win decidedly in both contests all variables being equal. I'm sure Dodge will answer quickly now that the Viper has been dethroned by both GM and Ford.

CTSVSL65AMG

I dont think the GT counts...its in a totally different price bracket. And if people think the Shelby GT500 will keep pace with the Viper and Vette....they need to think again.

But yes, dodge will respond...rumors are 605 HP....but we will see....its a good time for muscel cars, got to love it as of late.

i know for fact that they are faster than my CAR.. PERIOD.. i only driven the NEW ViPER... cuz my neight has one; it seems like itz a beast from a dig or roll..... now z06 i never driven one but neighbor said that they felt the same..
