The engine looks different !! Isn't it funny how ford takes pics like these??? . It's a tease and they intend it to be. They know for enthusiast will seek out pics like this and talk about it. Your sooooo tricky ford!!!

The pic has "cobra" in the title, so it's possible it's a Cobra, but who knows? I'm sure more pics will come out over the next couple of months. A Mach1 with a 5.4L N/A sounds just about perfect.

Thanks!

There were way too many topics on the same thing.

Crispy - the rumor about the chassis not being able to handle the torque in a Vert is untrue. From what I hear, the only issue about building a Cobra Vert at all is based on marketing projections and how much demand there would be for the car.

There seems to be a fair amount of support for it but so far Ford Corporate has not officially stamped a Cobra Vert as a "Go". My source has not seen a Cobra Vert Mule but he did stress that that does not mean one does not exist. He did say he thought we were at least a year away from getting to that point since Ford Corporate/SVT is focusing strictly on the Cobra Coupe at this point.

There IS a lot of disension within Ford (especially from the 'bean counters') about building cars like the Cobra. But it appears that there is indeed enough support within the Blue Oval's walls to see things continue to progress. Vert? Not sure yet. Coupe? That is a definite car that is coming and it will be sooner than previously announced.

As soon as I hear anything else regarding the potential Cobra Vert, I'll post it. [/b][/quote]
Thank you, Steve!
I appreciate the info......keep it coming!

Let the leaks begin. I had a blast last year when we were doing this with the '05 GT.

Spy pics, photoshops and rumors, Oh My!

It's problably a test mule and they didn't bother to remove the GT badges.

That, my friend, is a nearly stock 03 Cobra. Mine put down 415 with just a K&N and cat-back. A twin screw 5.4L better put down significantly more than a roots 4.6L with no effort at all.

03 Cobras might have been underrated, but not THAT much. They were rated at 390 at the crank, but to get 400 at the wheels they'd have to be making around 470 and I'm not thinking they were off by 80hp You might have gotten 415 at the crank with a K&N and catback, but you weren't putting that kind of power down. More like 415*.15 = ~350.

There is no way a 'stock' or 'nearly stock' 03 Cobra can put 415 hp at the rear wheels. Like it was pointed before, the Cobra's were underrated but not by 80+ HP.

Now, throw a chip, pulley, and exhaust in the mix, you might be at 415 - but not with just a cat back and a K&N.

Don't get me wrong - I'm a HUGE fan of the Cobra's. My son has an '03 that he just dyno'd at 440hp and 460tq at the rear wheels but it has got an AR chip, 2.8" pulley, Dynomax cat back, ported T/B, and a Cold Air setup. The car is an animal!

But a stock '03, even with the mods you listed, will not turn 415 at the rear wheels.

And that, my friend, is the truth.

Look at the motor that is sitting just below the mustang on the lift. Those heads are massive! They look a lot like the heads found on the previous Cobra's. Could that be one of the new Cobra powerplants just waiting to be installed??

Dan460

415 is high but not unheard of for a K&N and cat-backed 03-04. I've seen guys with healthy(broke in) 03s get 400RWHP with just the K&N FIPK. From what I've read, the 03-04 Cobra actually makes @425HP once it's got few thousand miles on it. I have the K&N FIPK, FRP FR500 cat-back, 2.95(mild difference), and a Predator tune and made 433RWHP and 430 lb.ft. The same day I did that I installed a 2.77 pulley for a friend and he made 442/470 and his only other mods where a cat-back and a tune.

After living with this beast, I will have to get a Whipple kit for my 05 as soon as they are available.

Anyone else notice the chrome trim around the windshield and A-pillar?

Actually, it's true. And I am by no means unique with my horsepower. A buddy of mine dyno'd 405 rwhp with a K&N and Stingers. And there are numerous people on SVTPerformance putting down 410-425 rwhp with just a K&N and cat-back. It's all in the K&N, actually -- just last week a fresh new 2004 Cobra put down 425 with just a K&N, still with the stock cat-back. Nice.

Here is the dyno I did one week after I purchased my car (got it used, with 3100 miles on the odometer, the K&N FIPK and Magnaflow cat-back was already installed). You can see that it loses a noticable amount of power on each run, as the heat exchanger gets saturated. The A/F ratio is via a tailpipe sniffer (read: through the cats), so it means little.



This dyno is no longer accurate, for predictable reasons . I just wanted a baseline before I did the bolt-ons.

CHROME? would be nice

You're claiming that a fresh, new 2004 Cobra with just a K&N is making ~500 at the crank. You realize that, right? An engine that is rated at 390hp making 500, that's what you're saying.

The only explanation I can possibly come up with is that these dynos are adding in the expected drivetrain loss to get those numbers. Those are C5 Z06 numbers, I don't see any way those are rwhp figures.

Dan460

The 03/04 Cobra is obviously underrated by Ford. Actually 400RWHP would be about 470 at the crank. These numbers seem to be pretty consistent with many other owners. These are way higher than C5 Z06 numbers which usually dyno around 350RWHP. The next Z06(C6) that is coming out might put down @ 430-435 since it is supposed to have 500 at the crank. The average 03 Cobra seems to put down 360-370 bone stock with a few freaks that make @380+. The Z06 is about 400 lbs. lighter so we need all the extra HP we can get.

I don't think that's chrome around the windshield(I hope not anyway) It looks like light reflecting off the rubber seal.

Steve

IF the dyno is accurate, those are unbelievable numbers. I would question the accuracy of any dyno unless they have proven and certified calibration/accuracy.

I'm sure many dynos will get within 5-10% of true but even if they are 5% off, that's a potential of over plus/minus ~20hp/Tq with 10% error twice that.

But, if they are dead on numbers then you have a beast of a car!

S197Cobra

I am satisfied with their accuracy -- I have been to a couple of dyno days on this dyno and watched many different cars do pulls, and the numbers are right in line with what they should be. Ford underrated the 03/04 Cobras by about 50 horsepower, even with the paper filter intact. It isn't really suprising that they are making so much power -- a stock 03 Cobra is supposed to have about 8.3 psi of boost -- mathematically that alone should put you close to 500 crank horsepower. And with the K&N, some people are seeing boost as high as 10 psi without touching the pulley.

So this is why I think Ford will up the rating for the next Cobra. If they could put in an air filter anywhere near as efficient as a K&N, and still meet all of their longevity requirements, it could easily be called a 450 horsepower car and still be underrated a little. Of course, I would much rather they installed a Whipple to get there .
