So the new GTs seem to be doing pretty well with the 3 link suspension setup...I'm guessing the 500 won't have much of a problem in stock or near stock trim. Only thing that's gonna hinder this beast it the fact that it's heavy, what with the iron block and bigger wheels, brakes, etc. 3800+lbs!! Going over the specs and projected numbers in the mid 12s at about 115-116mph, makes me wonder what they're gonna be laying down once the boys in Jersey and Houston get a hold of theirs. Dare I say a stock car nipping an 11.9999?? ;) :D

sea level I expect to see mid to low twelves however I dont see it kissing 11s with the weight and the amount of actual power it is estimated to produce.

member its only a little 5.4 with a twinscrew (stolen from whipple I might add) though it does come with forged pistons its still the ca ca fomoco I beam rods. turning up the boost will not be like the 03-04's IMO. it will be good to see.

Twinscrew? Eatons are twinscrews? Yea but the power that it is said to be making may not be the actual power it comes with. Could be much like the Terminator Cobras, which went mid 12s bone stock with good driving on a killer day.

the 07 is not going to be a heaton... they are using the same displacement twinscrew from the GT

07 is an Eaton. I read they couldn't guarentee enough twin screw units to meet production.
The Ford GT engine is force-fed by a Lysholm screw-type supercharger; the GT500 will use an Eaton R122 Roots-type blower and an air-to-liquid intercooler, adding 10 psi to the intake system at peak boost

Last I heard, but I don't keep up much. Kind of a bummer.

owned by the great spitfire... LOL interesting... wow I need to polish up...

I don't know about all that now. I'm sure there will be quite a few changes as they move from prototype into production.

I don't think at 3800lbs it will get into the 11s stock. :(

damn from a really quick read on MF you are right... it will be a heavy mofo... if it doesnt hit 11s stock a little gear will push it over the line

The rods used in the '03-'04 Cobras were Manley, just as they will be in the GT500. I'm sure the shortblock will handle considerably more power than they are being delivered with. Having a 2005 Mustang GT, I can tell you that there will be a ton ofpower to be found with nothing more than a quality tune.

...Alls I know is the Shelby GT500 is proclaimed by Ford as the fastest production mustang ever!!!,,,,I see mid 12's when it comes out,...and with tweaks to the 5.4L with the same heads as the Ford GT,.....I see this car no problem getting high11's!!...weight and all.;) :cool:

im hoping for some low/mid 12's stock . . .

When the published times come out, they will probably have it at 12.7, but I imagine they will run at least a 12.5 and I really hope they run 12.2s. Only time will tell, but with a set of slicks and gears I bet they will be in the 11s.

3664 - 2004 Ford Cobra curb weight

3800-3900 - 2007 Ford Cobra curb weight

stock 04's ran 12.9/12.8

now the new one has 110 more ponies but only weighs 250 ish more, does the weight out due the hp ? I would imagine mid 12's

The weight doesnt negate the horsepower, but it does take a pretty big chunk out of the 1/4 time. There really isnt a formula for weight vs horsepower but from what I always heard, every 200 lbs is soppose to equal 3/10s a second. I also heard that every 10 horsepower is soppose to be 1/10 a second. So with 110 more horsepower, it should be 1.1 seconds faster, but with the 150-250 lbs it will be slowed down by around 3/10th a second. The end result from this "logic" should be 8/10s faster or around low 12s. However, this theory is far from fact because of so many other variables and for the simple fact that 1/4 mile times are not linear. Meaning that just because it takes 200 horsepower to run 14s, doesnt mean it should take twice the horsepower to run 7s. In either event, the cobra is going to be fast enough for me....especially after the mods start :D

Getting into 11 bracket should be under $ 2500.00 depending on how much you can do yourself vs paying someone the labor. The very first thing is to get rid of those 3.31 gears, they are in the car for gas mileage to keep it from being hit so hard with Gas Guzzler Tax (Which it is getting hit with ) First Mustang I had was a new 83 GT and it had 3.08 gears, when I went to 4.10's it was a whole new beast. For driving on the street and some time at the strip the better gear will be 3.73 which will cost you approx $ 180 to $ 220.00 for the gears. New gasket and fluid another $ 50.00 est. Believe me just gear change and this thing will be like a whole new car. A little less gas mileage but I have a 03 focus for that :) But who can stop there, you will need some type of Air - Intake system, reflash computer, Exhaust 3 inch, high flow Cat's (which it has or maybe NO cat's depending where you live and can get away with) ( I don't run them :) ) pulley change on the charger, underdrive pulley on the crank all those mods are around $ 2500.00 and considered bolt on's. For those wanting every little bit a set of headers will help (hate the tightening all the time till they seat in so I will skip that step) hotter inginiton, dyno tune the computer instead of downloading maps. But the rest I will do for sure and those mods should be worth at least 50HP at the motor. Check some sites and see what has been done with a 03 cobra doing the same mods above how much HP they have gotten out of them and still have a driveable car. Plus you can put it back stock to keep the value when you... if you ever sell it. I have a sickness like allot of people no matter what it is I have to change it :) I bought at the time the fastest production motorcycle built a 2005 Hayabusa ( http://www.flairphoto.com/busa.htm) which runs 9.98 1/4 and have had it to 180 using a corrected Speedo and that was not enough I still spent over $ 3000.00 in mods to make it faster, lighter, and different than stock (Go to the address above to see) So believe me when I say mine is going to get worked on and being 45 minutes from a 1/4 mile drag strip it will make a couple passes in its life :) ! ! ! I am looking for 11's

Bill (busababy)

I'd be really suprised if the GT500 (not the pre-preoduction units C&D and R&T drove which were set rich, with traction control on and an early flash on the Spanish Oak) as a production unit, broken-in, with street-slicks dosn't run 11.90 and 100-teens. It's main problem is traction (57/43 weight distrib) and 3920lbs, but hooking it up with the right street stickys and some seat-time/solid shifts and it's into the 11s for this puppy.

I also expect that by SEMA in November, there'll be several kits to re-flash the S.O. chip and overdrive the blower to 12PSI. That with low restriction intake and muffs, will get you to just about 650 crankHP -- the design point for the botom end of the engine and the drivetrain (the rearend looks the same as the GT but the gearset and bearings are hardened). So, an afternoon in your driveway should get you and 1/2 sec off those times!!!

busababy...you have a sickness that is oh so sweet. I will be looking forward to your posts about what you do to your cobra, and if you don't mind, I will be doing the same mods...

I have a 2002 TLs (I had to have v-twin power)...zuki seems to know what they are doing with their bikes!!!

nice...

I just read the MM&FF article and they got it down to 12.24(ish). this will be a 10 second car with modest mods(and the right driver). The question is though, do you want it to be a 10 second car. My local track makes it manditory that if you are faster then 11 seconds you MUST have a roll cage in the car. I don't think I will be installing a roll cage in my gt500

with good track prep and a good launch, it should be able to hit high 11's.... if it's making the advertised power.... anyone get one on a dyno yet? :)

An E55 AMG @ 4050 pounds 469HP (probably more like 500) can run 12 flat, and some have run high 11's, totally stock.... check this one with timeslip, dyno and video:

I hope that it does better than the 12.9 that Car and Driver got out of it. MM&FF managed to get a 12.3 out it which tells me that the C&D driver couldn't drive worth crap!!!! I knew it was hard to believe that a 500hp Cobra was 0.3 seconds faster than my 305hp Cobra. :D

TheC&D car was also an April-level pre-production unit with a forced-on TC flash. The production car is quicker, I think. And the 12.25 was on street tires. I think there's a lot more in this car. Just a flash tune and tires should get into the 11s, IMO.

That's because most of the "RAGS" don't know how to shift a manual. There was no power shifting and they usually launch it way to high spinning the crap out of the tires,both resulting in alot of lost time. And yet sometimes too,they don't launch it at all with no speed-shifting equaling same crappy times. Morral of story,behind the wheel,"A Real Capable Driver"(as Evans proved in MM&FF)can make this baby scream through the 1/4 mile no problem!!! Low 12's stock, gears&tires high11's, tune,exhaust,gears,tires,smaller pulley& up boost(possible twin screw)and its easy high 10's!!! Now where talkin'!!!:cool: :cool: :cool:

I have a link to a real world 12.5 @ 115 run, but the board says I can't post a URL???

I know that the BIG name mags like Motor Trend, Car & Driver and Road & Track can't drive worth crap. I didn't know the one C&D drove was a pre-production one. It'll be interesting to see how quick a bone stock, even one with exhaust and a CAI will be.

FikseGTS, I'd LOVE to see that video man.

The ones the mags 'tested' with (April) had a pre-production flash (actual early production was still a couple months away). Also, you're probably aware that the GT500 (production version) has traction control that can be turned off. When on, if you launch at 3,400 rpm and dump it, the ECU senses that and specially manages the engine and TC as a form of automated launch control. The units the mags 'tested' with are believed to have a diferently programmed TC that was forced-on (can't disble) so the mag drivers didn't smoke 'em too bad. The problem with that is, as experienced terminator owners know, you can typically run a solid .3 sec better with TC off if you know what you're doing and another .4 or so power shifting (stock gears). My hunch is that's the diff betw the 12.7-12.9 the mags saw and Evans 12.25. Also, his run was almost certainly with a production flash since it occured at least 'two months later than the mags pre-production fling.

I also agree with the poster who said: gears and tires 11.99; intake, exhaust, more boost 10.90s-11.00; even at +/-3900 lbs that doable. In fact, I was told by a GT500 rep in April that Ford actually tested and planned for that since the drive train design point is 650HP and their plan from day-1 was to leave those adders to the aftermarket/FRPP, just like they did with the Termies. So I think those numbers are not only credible, they were sort of part of the total 'design' ;-)

Our baby may be a bit overweight, but at least the weight is all in making the car a solid all-around peformance GT tourer too. It's not just a hotrod with a big engine; it's designed to run flat-out all afternoon around a road course too which is much more demanding on the total vehicle than popping quarter-miles. You can take a 3V 4.6 GT add CAI, exhaust and Roushcharge it and, at +/-400lbs less, be as fast as a stock GT500, but it's other systems will go up in smoke flat out on a road course in a couple laps. Of course, you could beef up the bottom end of the motor (GT is good for about 450HP max), do brakes, swap the T56 for the 6060, brakes, cooling, etc, etc, .and spend a small fortune. That's one of the things that makes the GT500 so special, IMHO, it's a totally engineered 500HP package and, at MSRP <lol> it's a steal -- sweet! ;-)

and just when are you guys that have tag registration on these gonna take them out and give us some hard numbers.

I'm coming to a town near you so that you can drive while I :D :D :D :D

though it does come with forged pistons its still the ca ca fomoco I beam rods. turning up the boost will not be like the 03-04's IMO. it will be good to see.


I thought the GT500 had forged rods?????

Jason

I thought the GT500 had forged rods?????

Jason

I believe it does, and uses Ford's cracked-journal technology so when the rod cap is reassembled around the crank it is perfectly round. Dunno whether I or H in design, but Ford rep told me in April that the design point on the drivetrain, including engine botom end, is about 650HP (GT motor about 450). My understanding (from Ford rep) is that Ford will rely largely on the aftermarket (including FRP) to offer well engineered kits (CAI, exhaust, blower o/d) to get to that number [fairly easily], and that Ford evaluated that as part of design/testing. So, while not the Manley H-beams of the FordGT and Termies, the GT500 rods/bottom end is pretty stout.

I guess we'll see as some get broken-in and start to see some track time. I would think we'll see some aftermarket kits starting to show at SEMA this fall.
