Thats actually wrong ... the 03 cobras are over-rated on hp. Like was said above, dyno will show different than the factory. Its like the other year they did cobras, what was it... like 93-97 they had a exhaust manifold problem where they were actually losing ALOT of power. When ford got enough complaints they fixed it. But i read that they were having similar power problems with the new cobras. And at the seattle auto show i talked to one of the ford reps, who wasnt too keen on me asking questions about fords flaws. But I asked him about the problems with the new cobras, he said the clutch they use doesnt hold up very well. That would cause a big lack of power to the wheels... And thats something that wasnt even in the article i read. So with the clutch + whatever else, there is going to be a big loss in power. Im not saying they are slow, or bad ... im just saying they arent the all mighty super car everyone thinks they are. And its not at all hard to believe a 3rd gen with close to 300rwhp beat a cobra with 390 (claimed hp to the flywheel) So break that down, lets be nice and say they only lose 50hp to the wheels (which if you go by the standard 30% it would really be 117hp lost), then add the clutch problems, lose another 20hp to the wheels, plus the other power problems, lets say -10hp? pretty fair? I think so. Which only leaves us with 310 rwhp in a 3700lbs car. Sure it is still fast, but not as fast as that 3rd gen.

the horsepower to weight ratio is not the "end all be all" way of determining who will win a race, I'm quite sorry to let you know this but i have to constantly tell my friends who are rice burners and decide hey with my hp/liter and hp/lb i can beat a ferrari.



The truth is every race will be different and no one race can be recreated.



Also the reason he got the jump until third is because that's how the car is designed, it launches very fast with all that power under the hood, the top end area is weak tho (weak yet very strong compared to 95% of the cars out there atm)



i've seen those cobras run mid 12's stock, but it seems each one from the factory varies strongly. I actually heard ford is recalling a ton of them because something fucked up in the engine during the assembly process that is causing those glitches in HP. If that's true it won't be the first time, and prolly not the last time, that the SVT creations fucked up off the assembly line.



anywho like i originally said, tight race keep showing them how to do it out there, and now i expect you town run low 12s high 11s at the 1.4 mile.

well high 11's is far from what im hoping for im lookin for 12's. whoever talked about te power to rate ratio heres a side note.



i mentioned i was on lowboost (.80 bar) thats when i dynoed 297.1 i was .9 something bar(spiked, later fixed) but at .80 i have approx 285h rwhp well a little more. i dont know how signifigant that is but u gotta also consider for weight myself and my friend neither of us is too heavy approx 170 each and the cobra dude who didnt look like he coulda been over 200. either way i was very unimpressed with the cobra. after hearing so much about thhem to see how "fast" they really were it changed my mind about what i had considered the noble beast.



i also just read the article in car and driver comparing thecobra rx8 and g35 coupe, they tested the cobra to have a 12.9 1/4. impressive but easily beaten by us wankel boys:devil:



anyway im gong to the track on saturday ill keep u informed with my 1/4.

Excellent..

Hey Mike, wrong forum. This is 4 "kills", not "killed"! U people R full of ****! Am I contesting you're integrity on behalf of your race? U damn skippy! The Z06 would have torn U up on top if he tried...they can reach the 180 zone. The Cobra, w/o a chip, will limit @ 155. I very seriously doubt your modded FD could come close to beating a new Cobra outta' the hole. Are u sure it was an 03'? 1 dude said U better be glad it wasn't an R. FYI...an 03' Cobra will outrun a Cobra R. As 4 times, a descent driver produces mid 12's in a stock car. I know, I've seen it personally @ the local strip. Now giving U the benefit of the doubt and saying you're right, imagine what this guy can do. If he was to spend near as much as U did on his car then he'd be far into the 10's. BTW, they R not gas guzzlers: my mom's 99 GT got 23 mpg. Hey I love 7's...especially mine, but U R over-estimating them! This dude must have sucked or else he was @ 3/4 throttle. That's okay domestic-haters...the 05' GT's will slaughter the 03' Cobra (they'll have c. 400HP). Imagine what the Cobra will do then....

Yea, you're right.. there's no doubt that cobra's definately have their share of power.. and I have no problem with them, but the main thing about the RX-7.. is the Rotary Engine! (For being only 1.3 liters with twin turbos) and being able to run with a Big Bad Mustang Cobra (4.6 liter V8/supercharged) is an accomplishment. And about the amount of money per car.. think about it, you can get a third gen these days for prob. $10K (ebay) and the '03 Cobra's are like $38K (ebay) plus extra money spent on both.. the FD's the way to go.. plus I think it looks a hell of alot better than any mustang ever made. '05 mustangs will be bad though.. and they're using the 390hp V8/supercharged engine from the '03 cobra's. I seriously doubt that engine's going into the base or GT models..

Dude you aint nothing but problems. Why do you even come here. {dumbass voice} a McClaren Will kick a Z06's ***....It goes in the 200mph zone{/dumbass voice} The topic wasn't about corvettes... GUY!! It was about cobras. And do the research. An FD will beat an 03' Cobra. Look in any write up. In some it is as little a .1 sec but it is still SLOWER!! I am contesting your Ignorance for even posting. Oh and about the 05' mustang. Lets think here.....400hp? Its still a freaking concept. How do you know what it is capable of. Think before you talk.....

MazdaMike

the car was a brand new mustand cobra and he got a nice view of my ***. im happy that u saw a bunch of fast mustangs ive seen fast cars too. im just telling u what happened.



no **** a z06 would tare me apart at high speeds along with most cars over 70k. that z06 was modded so i dont think i could have taken him period does that mean i shouldnt try, i like racing people i cant beat just for the thrill. vipers are the best race cause theres no better noise to lose too damn they're sexy



so mustang boy u dont belive that i can beat a cobra... im a little insulted but maybe i can proove it ill see if i can do better than 12.9 tommorow. if so ill post a slip for u. maybe that will help (dar and driver rated the cobra with a 12.9 1/4)

When I was at the track last weekend there were at least 3 cobras there. The only one that was in the 12s was one that was slightly modded (exhaust) and it only ran a 12.5. The rest were running low 13s. Sure they may have been shitty drivers, but that is who you run into on the streets. Also, keep in mind that some magazines "correct" their 1/4 times and horsepower #s due to enviromental factors that they have no control over, BS IMO. Car and Driver and such mags do say the cobra will run high/mid 12s, but I've yet to see it done. Check out this months SCC mag. they have a little artical on the cobra (kind of), and they were only able to get a 13.2 out of the cobra after making MANY runs down the track. I agree with most of the people, the Cobra is WAY over rated.



Hey dumbass, you are talking about a POS GT, not a cobra. My NA vert will get over 20 mpg, but that doesn't mean that my turbo will get the same gas mileage, even though they have the same displacement. Use some logic here.

lol, you tell him!
