Let me just say that you cannot fully appreciate this truck unless you get on it.


I was driving to work today (talking to mother on UConnect, of all things) when I notice a late model cobra behind me. Guy was young, he was driving aggressively, so I figured he'd play. We were caught in some traffic so at the next light I asked him if he wanted to go
"sure"

we were not first in line but second so we let the cars in front of us go and then took off. It was not even funny.

I left him like he wasnt even there, it was great

Then of course he wanted to go from a roll. We took off from about 20 and I walked on him, through every gear. We ended up doing 120 when i just called it a day, he was so long gone, and then had to make that turn off the road.

It was an '02 cobra N/A but had work done from what it sounded like.
Just another kill:)


All the while, my mom was on UConnect wondering what the hell was going on.

I was a believer before, but just had to say

"Man I love this car."

Happy thanksgiving

Untouchable

sweet kill. haven't found many up here in Canada to play with. maybe I'm better off since there are cops everywhere...

Nice Kill, sounds like an '01 (there were no '00, '02 Cobras). FWIW, they can be pretty quick with bolt ons, high 11s@113+.

Sweet kill thanks for sharing it. I just never get tired of hearing these kill stories especialy when it involves a Mustang. I do like the car I just can't stand most of the guys who drive them. I've also seen some impressive times from these cars with decent mods and good drivers.

01 Cobras put down right around 300rwhp. Nice job!!

Yes, those Cobra guys can be real jerks...'specially if you talk about gears for the rear end..;) :p :D

Cobra guys are worse losers than the ricers, they at least know on some level that they suck (for the most part)

well n/a Cobras. 03/04 Cobras wouldnt be losing....

LOL, some people...;) :p

Are you sure? :confused: I just read an article on the Shelby GT500. It ran to 60 in 4.4 and the 1/4 in 12.7 and that's a 500hp car with an experienced driver. That's faster than our Jeeps but not by much. I didn't think any of the Cobras were that quick. Not trying to give anyone a hard time here, just curious.

FWIW I saw an entry at Dragtimes for a Shelby GT500 from an average driver and he put down 13.410 in the 1/4. I'm sure he had hook problems.

A little info on the competition:
'03/'04 Cobras trap 110-113mph stock with a good driver at a well prepped track. That means that by the time we hit third gear they're going to blow our doors off. Their biggest downfall is our largest advantage, standing start traction.
As for the GT500, I just beat on a stocker last Friday. They are much faster than us in the second 1/8 of a quarter, or on the highway. From a dig to say 60mph we can hold our own, keeping in mind they have an idiot proof launch control setup that allows for repeated 4.5-4.6 second 0-60s. Decent to good drivers are running traction limited low to mid 12s@ 115-117mph+ off the showroom floor; averaging ~440rwhp/425rwtq @ 3850-3900lbs depending on options.
When the mods start the slaughter begins...With just a tune, they're pushing 490rwhp/470rwtq on 93 octane. Full exhaust, pulley, CAI, and tune on the stock blower/longblock will net you right around 600rw.
With slicks, gears, a mail order tune, and O/R X pipe a 4250lb+ (w/ driver) convertible ran 10.4s@126+. Evolution just ran 9.9@141mph with the stock blower (ported) and a 75 shot, they're shooting for 8s with the 2.8KB. Video here: http://www.svtperformance.com/forums/showthread.php?t=338509
You can make 750rwhp on pump gas/810rwhp on race gas by merely swapping to a 2.8L twin screw--stock exhaust, etc.
Then of course, there's the possibility with twin turbos. I present you with Joe's dynograph, he hunts turbo Busa's on the highway in his Ford GT, they're going for 1500rwhp on turbos alone next week: http://www.bullseyetechnology.net/turbogt1400.pdf. Video and story of the car/owner here: http://www.imvfilms.com/joesgttt.php
The graph shows the built 5.4 4v with 25lbs of boost plus a 75 shot with the present smaller turbos--the stock motor made 903rwhp on straight 93 octane and 19lbs of boost. Yes I realize it's a Ford GT but they are essentially the same motor as far as power determining parts are concerned, and twin turbo GT500s are already on the way.
I saw the 13.4@104 run on video. First time driver, brand new car, on a non prepped cold track. Pretty sad:eek:
With all that being said, after back to back drives over the same course I still like my Jeep better as a daily driver. Even though much to my surprise, the GT500 had a significantly smoother ride lol; it felt, tracked, and accelerated like a blown AMG E55 on the highway.

The GT500 is turning out to be the beast FORD is known for in the Mustang line since '03 Cobras came out. The doom forecasters quoted vehicle weight, FORD history from the 99s and dug up the hyperpathetic skeletons of the past. And, although correct about it being as heavy as Rikki Lake at a Las Vegas Buffet after a binge of chronic, the engineers seem to have worked out the lumps and delivered a nasty 4100lb earth missle. I too have heard the 10.something stories and look forward to watching the FORD faithful get their come upperance.

Wow! Great info thanks. Can I asume that all of these Cobras have the 5.4 and not the 4.6? I've always heard that these cars are easier to tune and take better than most other cars to simple mods. It's just so amazing to me that those numbers can be achieved with that motor. It sounds like stock for stock though we can hold our own in streetlight duels with these cars which is pretty impressive to me. It doesn't seem very likely though that $ for $ mod for mod we would see the same results in our GC's. Makes me wonder what's so special about these cars. I think Ford has done a great job with the new Mustang design I really like it. It's nice to see them getting back into the game after being so passive for so many years. It's a shame though that so many of the guys driving them in my area are such idiots. I don't know what it is but these guys think they are invinsible driving Stock Stangs. I don't think I've ever come accross a Cobra in my area with the kinds of mods that were just posted here. With that said I feel pretty confident lining up with them in my SRT8! :D

Since I have the et slips & dyno sheets, I'll step in with some info on my late 03 Cobra. Stock Eaton supercharger with a 2.80 pulley, Billetflow throttle body, homemade CAI with BIG K&N filter, Stainless Works catback(no headers, no cats), stock gearing, & stock Goodyear F1s, I ran a 12.02@119. The car weighed just shy of 3900 lbs. with me aboard. With the mods I listed, the car dynoed at 455/483 SAE. You'll find quite a few 03-04 Cobras with MANY more mods than I had. 600 RWHP isn't too difficult to come by and the new Shelby GT500 is going to eclipse those numbers quite easily.
Would I like to have a Shelby GT500?....hell yes. Would I trade in my GC for it?.....NO. At this time in my life, the GC "fits" just right. Give me a means to create a custom tune and I'll put my GC in the 12.7s. I can live with that quite nicely, thank you.:D

Wow! Great info thanks. Can I asume that all of these Cobras have the 5.4 and not the 4.6?

The '00R had a naturally aspirated 5.4, and the GT500 (07-10) has a supercharged version of the same motor. All other year Cobras had 4.6s, all 4v, supercharged only in 03/04.

Factory forced iduction is a wonderful thing, especially when you're shoving boost through a four valve head--DOHCs really shine when paired with a turbo, the extra exhaust flow is a huge bonus in this regard. Although we can make some decent power N/A, comparison to FI is futile, and simply not fair. However, with the right engine management system, a forced 6.1 Hemi would make very impressive numbers in its own right.

I couldn't agree more with this statement.

Thanks for the clarification on these cars. It sounds like the supercharger makes a big difference on the '03 and '04 Cobras. I know some here have tried adding boost to there SRT8's by way of a S/C but the results haven't seemed to fair too well. I almost put one on my 5.9 but with almost 100K miles approaching and a slew of problems on the horizon the SRT just made more sense. I would like to add some more aggressive mods like a S/C, I'm just concerned that it would require some serious reprograming of the PCM/ECM that I'm just not qualified to do. However the GT500 would look really nice in my garage parked next to my SRT8 and from what I can tell much more fun to tweak. Much of my interest in the GT500 has been peaked by a client of mine who has been giving me a hard time about my Jeep. All in good fun of course, but he's planing on geting a GT500 and is just dying to take me out and "school" me so to speak. He said it's probably the only thing he can afford right now that could give my Jeep a run for it's money. He might be right, maybe he's been doing his homework. ;)

As an added note, if the GT500 doesn't do it for you how about the FR500? 550hp 0-60 in 3.9 sec and the 1/4 comes in 12.1@123mph. Sticker price? $225,000!! :eek: Hardly seems worth it when you can get an '04 Cobra to run 10-11's for a lot less money.

No problem, I always like to know my competition as well, lol.
We don't exactly have forced induction friendly static C/R with the 6.1s. I agree reg. the lack of an aftermarket tuning solution. After a full exhaust I'm going to wait it out and see what happens before going H/C.
Tell your buddy you'll race him for $, just make sure it's raining out;) 0-60 it will be close, but when you hit third gear he'll pull you/us (assuming he can drive) like a raped ape.

The Man Racer (Boy Racer is $125k). I realize it seems like a lot of money but the amount of labor put into these race cars, and they are race cars at this point, is absolutely insane. I'm not a fan of big bore or stroker modular motors however. I had a 324 (5.3L big bore/stroker) prior to the 550rwhp N/A 5.4 in my 98 Cobra. There's very little gasket sealing area on a big bore mod. block, not to mention very little meat. Hence they can eat rings, and have on occasion even leaked coolant into the cylinder (N/A applications to boot) causing a windowed block.
You are correct reg. the 03/04 mod per dollar scenario, it's not hard to get them to run an impessive number at the strip. Obviously on a road course the man racer would eat its lunch. Different cars built for different people with different intentions. I'm just glad Ford, a company in serious financial trouble, hasn't completely given up on factory performance of late. :D
About the acceleration numbers, you have to remember that's on a full road race suspension as well. Tack on 4-5mph and knock off at least half to seven tenths of a second by switching to a drag optimized suspension and DRs or slicks.

Would have been nice if Jeep but a SC on the 6.1 as standard...then there really would not be much of a debate with the Stang
