1 week before I left for Japan, I was comming home late from crusing with my wife. A black 03 cobra comes up next to me on the street and stays at my side for about 10 minutes. I normally don't race with my wife in the car, so I just chilled. About 15 minutes later, we both catch a light. I knew I had to race him, so I watch for the other light to turn yellow. Right before our light turns green, I stall at 2000rpm and hit it as it turns green. I hear his tires roasting as well, but I was already 2-2 1/2 cars up. I shut down at about 70-80. My wife was pissed, but I was happy.

 

Awesome kill man. Those cobra's are pretty quick.

 

Nice, what were the dyno numbers you put down? Any track times, sounds like you have a killer combo there.

 

They are not as fast as you would think! I raced and beat a Chracoal grey 6-speed '03 Cobra from a red light to 115-120 and I raced and beat him again from a roll.

But, they sound nice! You can hear that supercharger whining like hell !

 

Yah I love the sound of the whine. My best dyno numbers were 331RWHP/376RW ft/lbs @5500 RPM. I will try to get my dyno sheet on here because my power curve is awsome. Both my hp and torque didn't peak until I let off. I would take it to 6200, but I think that's too high. Might make a few more hp and torque though.

 

Sounds like a good combo. What RPM was your torque peak at?

 

good kill

 

good kill..

i took an '03 out in the summer myself spraying 100 shot on him. he does the most biggest burnout ever covering me in smoke. so i had to lay it down. i didnt take him no more than a car but i still beat him. talking bout being pissed.

 

I can also take em from a stop by like 2-3 cars but they always seem to catch up by 100. I would say nice kill man. Wish I was closer to sea level so that I could beat em too (5800 ft).

 

thats crazy, but verry nice kill.

 

My peak torque was also at 5500rpm which I found very weird. I went to the track, but my tranny is so messed up on the 2-3 shift. I didn't have time to fix it before I ran, but I went 14.20 @ 85 MPH (because of the tranny) I hit a 2.06 60' and a 8.157 1/8 @ 77, so I know i could easily hit the low 13's, but 3rd doesn't want to catch for anything. Oh yeah, just for fun, here is a pic of my motor when I first put it in. Took about 3 days.

 

That Cobra owner couldn't hook up, or else you would have not won. If you raced to 120, he'd have caught you. Those cars put at the least 370hp at the wheels plus they're kind of heavy. That's why some of you may think they're not fast from a stop. Nonetheless you still beat it, the car w/ more hp doesn't always win.

Mike, you do have some major hp if you beat a 03 cobra from a roll.

 

Seems like the MPH is waaaayy off. I trapped 76-78 in the 1/8 with mid 14 runs at 96-98. You should be in the high 80s in the 1/8 and 110 or so in the 1/4.

 

Haha, 14.2 at 85mph? Not laughing of making fun at all, but I ran 16.45 at 82 mph. Either your track's timing was off that night, or your tranny is already dead. 14.2 is definitely good for at least 95 mph. Do you have any suspension mods? Your 60' isn't that bad, but with all the power you have, you should be in the 13s. Good thing you stopped by 80mph, because he would have had the advantage from there.

Yea, from the roll, we were doing about 50 mph then both of us stomped on it!

Keep in mind, the Cobra has a six-speed AND 3.55 gears.

I have a six-speed and 3.23 gears.

If I had more gear (like 3.73's or 4.10's), I would have put more links on that Cobra.

But yea, my car is ALOT lighter than the mustangs, I will give the Cobra that (they are pretty heavy).

I did alot better against it from a stop. Only had him by a car or so from a roll (50 - ~100)

 

Cobras at sea level are going to faster too...

 

Yeah you beat one with a modded monster of a car. I've seen em run low 12's and trap at around 118 with a H-pipe and a pulley, not too shabby.

Trying to get that thing to hook on stock tires is a nightmare.

 

lol, yup

 

370hp at the wheels??? Theyre only rated at 390hp at the crank, I realize they are probably underrated, but by that much?

 

I've seen a bone stock '03 Cobra dyno 367 hp at the wheels at MTI (motor sport technologies). So, believe it!

 

I beat a cobra with exhaust at the track with my bone stock 330 horsepower crate engine, and he only had 1 mph on me (we had identical 60 foots). He has since bought drag radials, and if we raced again (me being on radial T/A street tires), I would absolutely destroy him. He always runs in test and tune now so the oppurtunity has yet to present itself...

03' Cobras are not the super cars everyone made them out to be when they first came out.

 

Yes... and with a few bolt ons... mid 400 rwhp and the same torque. I am not a huge fan of these cars but after my friend dave went 12.7 @ 113 (he had a catback, when i thought he was bone stock, sorry) I gained a little respect for them.

 

So what, I was off three. That must have been the most gutless 03 cobra, only putting 367hp at the wheels....geez.

 

I have seen dyno sheets of guys who have an x-pipe, pulley, intake and a few other minor bolts ons put 450 to the wheels. They say that less than 1000 in mods in those things gets you over 450rwhp.

 

I have eibach springs, KYB struts and new poly bushings. That is the extent of my suspension work as it is. I am in japan, so sorry about the delayed responses. And yes, my tranny is pretty much dead. When I first dynoed it, I tried in 3rd. I made 51 less hp, and 72 less torque. My power curve went up to those numbers @ 3000Rpm when he stomped on it, then went down until he let off. Pretty ugly. Also, I saw a 03 cobra with full exhaust, intake, and a 100 shot dyno 623/712. It was sick!.

 

So full exhaust and an intake and he was pushing 520 rwhp (assuming that his nitrous kit was rated at the tires)? I find that hard to believe...

 

A cobra is much less affected by altitude. Just lake any supercharged or turboed car, they still perform well at high altitude. This means at sea level, the NA Camaro will improve more than the SCed cobra. Get it?

 

Also, when the cobra dynoed, his friend was spraying the intercooler off with his spare nitrous bottle. I don't know how much that affected his hp. Also, i am not 100% sure on the mods, but that is what he had on his Dyno database.

 

Any difference in the '03 cobra and the '04? Or are they about the same?

~Matt

 

Ok, don't want to start junk here, I can't stand mustangs(for the most part). But, give me a break. I don't care what magazine came up with what dyno #'s. Dyno #'s mean absolutely jack squat to me after watchin an '03 Cobra run 11.89 with only slicks and launching at 4k. Yeah, he had slicks, but, he still ran 11's in a "stock" Cobra. They may not be "super cars" to you, but, 11's from the factory qualifies to me. As far as I'm concerned a blower from the factory is not "stock", but, hey they had to do something, they were gettin raped by the SS and T/A's...all that aside that's a good race man, nice kill, just wanted to say they are not ALL that slow....

 

Unless you are the owner of the car, you dont know what he has done to it. There is a cobra on drag radials at my track that runs in the high 12's and it only has exhaust (that i know of).

My friend Daves car...

376.7 rwhp 364.9 rwtq.... STOCK...

12.612 @ 111.66 with a catback and filter.

 

Let me see a LS1 pull that trap speed with exhaust and a filter, THAT ISN'T HAPPENING! I dislike Ford but the SVT team got it right with the Cobra.

 

LS1's arent supercharged.

 

And to further the debate Ford needed a DOHC V8 with a supercharger to run with GM's "outdated" pushrod LS1 motors, and it still does not hold a candle to the LS6.

 

We know, that's why Ford got it right w/ the new Cobra. GM didn't. j/k. I think if the f-bodies would've stuck around, we'd have seen an ls6 or possible supercharger upgrade.

 

GM has supercharger kits for their damn ecotec motors, I dont see why they wouldnt have.

 

blah blah blah blah blah blah, run what you brought.

I guess I'm a loser for eating LS1's with my turbo right?

That fact is brand loyalty aside the Cobra is a badass car, case closed.

 

The car pulled 113, go to the site...

Ford didnt need one, but oh well, say what you want... and when you praise the GTPs and such remember... GM needed the SC!

 

reread what I said lol. I wasn't denying the Cobra, I was saying a LS1 wasn't gonna do that.

 

I know, but I just wanted to let you know he trapped 113... I knew you were sticking up for him.

 

ahhhhhhhhhhhhhhh ok

 

Doubtful... GM having a car faster than the Corvette is a no-no, just look at the GNX and Formula WS6/LS1.

 

LS1 vs. Cobra debate is fun, but kinda off topic.
