A bunch of guys at work including 2 owner's, one of each, are arguing about who's faster, more powerful etc...
I need some Dyno sheets, time slips etc to pass around...
Any good links????

 

Id say its safe to say the Cobra is faster

 

Unless the Cobra driver is a complete putz, the Stang will hand the goat its ***.

When's GM powertrain gonna whip up something that compete with that damn thing anyway?

I want a factory turbo 5.3 damnit...

 

lets see 390 hp vs 350, weight advantage going to the stang, torque and hp going to the stang, do they both have irs? Not totally sure about that one i know the goat does. But in either event, Stang will win by far. I am this close to tradein in my car and getting me a nice 26k dollar 04 cobra. Funny how even when the camaro was going out of production the prices for the SS's never fell below low 30's.

 

Cobra is $2000 more, 50lbs. lighter, has 40-60hp more, 35 more torque.

The Cobra is on avg. 0.5 sec. faster in the 1/4mi.

The LS2 '05 GTO should fix the HP problem

 

you can get a new cobra for around 30k, easy. while you can get the goat for msrp.

 

I can get a 04 fully loaded cobra for 26k!!! Thats almost 10k less then what the gto is going for!!...my vote is clear Stang wins hands down. the LS2 is what a 7.0? Pushin how much hp? Not 400?

 

The Ls2 is 6.0L, and it's rated at 400 horses in c6 trim.

 

if you are going to compare future ls2, then might as well compare it to the new cobra v10, lol. 500hp.

 

$2000 more?!? Yeah...MSRP. New '04's can be had for $32-33k and there are quite a few '03's still on dealer lots for the taking. People are getting brand new '03's for as little at $28.6k. Has anybody bought a new GTO for $26.6k? I seriously doubt it. I've heard of them selling for $500 over invoice...which I imagine is in the $31-32k range.
An '03/'04 Cobra is listed at 3,665lbs. GTO's are listed at 3,761 for the 6m cars and 3,774 for the A4'...that's about 100lbs difference.
6m GTO's are dyno'ing around 300-310rwhp. The A4 dyno's are in the 290 range. Very few '03/'04 Cobras dyno under 360rwhp. In fact, the vast majority of them are over 370rwhp SAE corrected. And they're a heck of a lot more than .5 quicker. One guy claimed a 13.3 in a GTO (which I still personally doubt) and SLP apparently ran a 13.14 in one. Those seem to be pretty darn unusual times since everybody else is running high-13's/low-14's.

GTO is a nice car, but an '03/'04 Cobra is going to trounce it.
It'll be interesting to see how it does in '05 if GM puts in the LS2.

Based on MSRP the Cobra is $2000 more. Dealers around me were still charging MSRP a few months ago for the Cobra, that is cool that they can be had for so cheap in other cities now. GTO price should drop later this summer.

I read 3725lbs. for the GTO.

Most Stock Cobras I have seen do the 1/4mi. in 12.9-13.0 on avg. GTOs are in the 13.4-13.6 range on avg.

The next Cobra will not be out until 2007 so why would you compare it to a GTO out this fall?

 

I think Yahoo! lists 3725 as the weight on GTO. It's actually higher than that...as I previously posted.
I've seen stock Cobras running 12.5-12.8's, and the internet if rife with claims of mid-12's in bone stock cars.
I haven't seen any GTO's at the track this year, and aside from the aforementioned 13.3 claims and the SLP car, I think I've seen one owner stating he ran quicker than a 13.6. In fact many of the M6 times I've seen have been in the low-mid 14's.
IMO, a safe bet is that equal drivers, the GTO is a solid .8-1.0 behind an '03/'04 Cobra.

50HP difference and close to the same weight and your saying 1 second So the LS2 GTO should do a 12.5 by your math.

 

I never said 50hp difference...you did.
Read my first post. It's more like a 70rwhp difference (that's rwhp!) and 100lbs.
So yeah....I'll stick to .8-1.0.

GTOs run about as quick as Mach 1s, which are about 0.5 seconds or less behind the Cobra in the 0-60 run.

GTO's IRS setup does a superior job of transfering power to the rear wheels, which Cobras are nortorious for not being able to do succesfully. So to answer which is quicker, it's Cobra...but not by much (and by waaaaaay less than 1 second).

As for weight, GTO's at a disadvantage, but it's less than 100 pounds. Not bad for a body structure that's overengineered versus one that has a unnerving tendancy to buckle in half on head on or offset collisions (right in the center of upper doorframe to be exact ).

Regarding price, Cobras retail for $35,000, over 2 grand more than GTO. Glad to see there are still instances where someone can yank a deal out of their dealer (though I'm not inclined to believe that "$26,000 Cobra" story, even for a second), but GTOs are still new, and are just now drifting to list price.

As far as which engine cranks out the power, it's no contest. Cobras, though rated at 390hp to GTO's 350. But while GTOs actually make 350 (give or take 5-10 hp) Cobras are actually putting out closer to 430! By right the Cobra should simply smoke the GTO, yet the Cobra can't even clearly outrun the 330 horse Mach1 Mustang. Again, it's that jerryrigged Cobra IRS.



So if the argument is who has the most power, it's no contest. Cobra gets it by a big margin.

If the argument is who's quicker, it's Cobra, but it's by a humiliatingly narrow margin. Cobra's are speed governed to 155 (like the GTO) because it becomes unstable (unlike the GTO).

Cobra has oddles of horsepower, but GTO does a far better job of putting it's power to use.

As for price, Cobra gives you a supercharger and head of the line dealer service, while GTO gives you a fully loaded, comfortable, great handling, high speed freeway tank, so it's a matter of taste.
