Weight isn't a factor above 120. Aerodynamic drag is. The Vette destroys the Mustang in this regard. I don't know the figures, but it'll take more than 100rwhp to overcome the drag coefficient of the Mustang vs the Vette at 155+. Of course, Cd^2 gets exponentially larger the faster you go.

My point about the C&D varations between tests and cars is proven here.

Paragraph 2 where they state the 03 cobra runs 12.9@111

"In terms of power delivery, shift quality, steering feel, and noise levels, the '03 Mustang Cobra offers quite tolerable levels of comfort—particularly in comparison with the Cobra R, whose performance it now so closely matches. (The '03's 12.9-second quarter-mile at 111 mph is actually 0.1 second quicker.) The ride is still a bit too firm, however, and although that might trouble owners living in colder climates, the upside is a well-balanced ride-and-handling compromise. "

And in this vid where C&D claims a 1/4 mile time of 12.0 @111 for the 03 cobra.

Thats a huge variance.......Any questions?

Like I said man at least this (C&D)was controlled testing by engineers and professionals rather than two guys going at it on the streets, you just can't come to a logical conclusion that way for the above reasons. Much better to eliminate variables in a mag comaparison. The drivers, the track and the air was the same for both cars that day. If the times suck, they suck for both not just the one. Gotta get over it man. The GT 500 rocks when modded, I've seen the video's. But stock, it's not going to take a C5Z in capable hands.

ZXMustang

Agree to disagree.

02ZOh6

That is definately hilarious dude. When have you ever seen a stock Cobra run remotely close to that on street tires? That segment may have been on C&D but make no mistake that Coletti and the SVT team reported those numbers and were putting on a show to sell cars. Those numbers were never printed in any magazine for any Cobra they officially tested. That video was to sell cars and SVT was obviously exaggerating the Cobra's times (they wouldn't do that would they? You remember the 01 Cobra's that didn't produce the 320-hp they were supposed to?). I mean the best Evan Smith, a highly regarded racer whom I'm sure you're familiar with could do was what, 12.4?
The C6 and GT 500 test was a real, same day, stock cars, same drivers comparison that C&D actually performed. They didn't take numbers from GM performance division and SVT and print them.

ZXMustang

Who knows? Its all speculation anyway. Who really knows if those numbers came from SVT or not. By the looks of the vid, they obviously drove the cobra. Anyway, no big deal.

02ZOh6

I agree, not a big deal. But in the link I posted there is no confusion.

What idiot would even think the driver of the Shelby wasn't racing me, what was he doing, trying to tell me I had a low tire from 80-165, come on? Also, I have been racing cars for over 10 yrs, on the track and an occasional street race, I have run many low 10 second passes at HRP. I'm not making exsuses here but, I did have a full tank of gas and a 200lb passenger, with an after market stereo system. The Mustang hauls *** no doubt, but in the end I won! The question of wether or not I can drive a car is out of the question... If you can put a 6spd TA on gas in the low 10s consistantly you sure as hell can drive a stock Z06 on the freeway!!!!

UL LOSE

You just didnt listen correctly. They said A 12 sec. 1/4mi @111. They NEVER said anything about a 12.00 They just stated it is capable of a 12 sec pass with the mph in the 111 range.

ZXMustang

Ok, you win. feel better? good! You could be right about the vid, but why would they say that when they give the correct 0-60 time and valid hp and tq numbers?

Wow....

Still going?

I just had a big long response to all of this...then, at last minute, deleted it, cause I know I would have came off probably wrong.

Anyways. Yea... what 02z06 said.

the only thing close to were I live is a GT with exhaust....one of these days

c5z06: 3150lbs 405hp 7.7 lbs/hp
gt500: 3900lbs 500hp 7.8 lbs/hp
they are about equal there but once you take into effect aerodynamics, the z comes out ahead. the irs doesnt seem to limit their traction either. im sure the gt500 times will drop as people get more practice, but for now, the z owns

I guess not...considering they don't have an IRS.

Every review ive read on the GT500 has just been a huge dissapointment...

Evan Smith tested the 03 cobra to a 12.4 (390 HP)

Evan smith tested the C6 to a 12.2 (400 HP)

He even tested a 2001 rt10 viper to an 11.7 (450 HP)

But then here is a 2006 GT500 that only dose 12.2 with GASP (500 HP) that he tested as well....


OK the 1/4 mile I can deal with...i figured it was just heavy and was getting a slow start HINT.. The 4.5 0-60 mph times...But that it would pull like a raped monkey on the 70 mph and up end...WRONG..

C6Z06...0-150 mph in 17.5

SRT 10 viper...0-150 mph in 19.5

Gen 2 viper ...0-150 mph in 22.0

C5Z05.... 0-150 mph in 25.0

C6 coupe...0-150 mph in 26.0

gt500...0-150 mph in 30.0

03 Cobra...0-150 mph in 32.0

C5 coupe...0-150 mph in 33.0

Seriously...A base C5 coupe running a 13.0 at 109 ( car and driver tested a convertable c5 to these numbers aginst a convertable 03 Cobra)would give the GT500 a decent run in the 1/4 mile and wouldnt be to far behind to 150 mph...

OK 3 seconds would mean that the C5 was pretty far behind at 150 mph but still...Come on. The C5 came out in late 1996

The motortrend this month, maybe last month now. The 500 HP american rocket one. on a road course the gt500 was only behind the viper and vette by 3 seconds. For all the weight complain and the bulkyness of it I say thats pretty damn good. Yeah the 1/4 isnt great but its got alot of weight to get moving and yeah its square jawed with no huge aerodynamic help but even with all this it didnt far as far behind the viper and c6 z06 as I thought it was. (and I have grown up under a ford roof) I picked up the mag and said yeah right the GT500 is gonna get spanked, yeah it lost in pretty much everything but not by much. And that is pretty impressive for this square jawed pig of a car to keep up with two light nimble aerodynamicly sound cars on a road course and mostly keep up in a straight line. Id also be willing to bet not every single person talking **** on the GT500 has a car that would wax its ***, So why not just admit its a pretty respectable car to even be close to the same class of the C6Z06 and SRT10 Viper.

Yeah...but, think of 3 seconds a lap....how bad it would finish. Other then price, I don't know why they did a comparison with these cars, the viper, vette, and...no offense, but the mustang(as unique as it is)...?.... they should have used the ford GT. Again, i'm guessingthey didn't, due to the price tag of it.

...as far as respecting a car that goes 12's outta the box....well, I think just about every LS1 on this site is capable of doing just that, stock(atleast high 12's). Soo,...as far as cars on here not being able to beat a stock one?...I dunno about that bro. I have a hard time having respect for a vehicle, that comes from the factory, with a supercharger,...and still has trouble with stock, all motor cars.

Take off the blower, make 500 flywheel horsepower, you'll get my vote for respect. Otherwise, the factory blown fords outta be giving respect to the naturally aspirated V8's that stomp on them.

Soo....like steve says..."no worries"
