I can almost understand taking an Elise over a Cobra, they're both rare and the Elise is amazing, but a MIATA?!?!). They even said that the Miata had twice the "Gotta Have It" factor... we're comparaing a Miata to a freaking Shelby Cobra here. I lost faith in them pretty much instantly with that article.
holler said:concerning tire size, some of you are not looking at the entire picture.
technically 235/55/17 is using MORE rubber then 245/45/17.
How so you may ask?
due to higher profile, the diameter of the 235/55/17 tire is 1.5 inches greater then 245/45/17. that's a lot of extra rubber compared to marginal tire width difference. that's about a 1.6 inch taller tire! with the better weight distribution over the axle, I bet traction will be just as good if not better compared to the typical gatorbacks. especially if you take in account all weather types.
But my point is they have dramatically changed the weight balance. And people move things like batteries to the back end to get more weight on the back wheels. Or why funny cars and dragsters try to get as much weight on the rear wheels. This is exactly what Ford has done with the new mustang. And they changed to a taller gear (3.55) in the gt.hotmustang331 said:Hmm that taller tire is more rotational mass, thus hurting performance by reducing RWHP. And to the other guy who posted to my earlier post, yea you may be right about the suspension making up for the tire width difference, but still try to hook the current stangs with 300HP....you really cant get any traction,thats basically my point.ford should have put some 275s on the back.BTW how wide of a tire is possable to fit under there?Just wondering ifyou can cram 315s under there like the current stangs.

RustyFox said:That may be true in road racing, but not drag racing. In drag racing you want the sidewall to "work". The sidewalls in SERIOUS drag cars (including 7000+hp top fuel cars) have a large sidewall. Why is that? I don't know the exact physics, but I do know that large, flexible sidewalls are needed for ultimate traction from a standstill while racing in a straight line. Look in an NHRA rulebook, you can run tires with a short and or rigid sidewall in Top Fuel, Funny Car, Pro Stock, etc, etc. Do they? No.
Ray III said:why would the japs sue Ford over having a similar crumple zone when Asian carmakers are so notorious for copying domestic styling?
Does it bother no one that the new Civic looks nothing like the old one, but nearly identical to the Focus?
Or that some Honda and Toyotas (can't remember which) cars have Mustang style front ends?
I think the new Celica looks suspiciously like that gay FWD rendition of the cougar.
Basically there is no end all be all of carmakers... Europeans make gay cars with some awkward features that make no sense sometimes. The Japanese are shameless copiers that end up developing styling laughingstocks like the Element that cater to ricers. American cars don't drive worth piss and generally break down more.
On top of it all, you need a degree in computer science and limitless patience to try and repair one of these crammed together peices of junk. I just stay away from all new cars altogether.
mball said:Sounds about right to me, every estimate I have seen has it running 0-60 in 5.2-5.5 and the quarter in 13.9-14.2 GREAT!! Ford has finally got the Mustang to be just as quick as the Camaro Z28 was 11 years ago...they should be ashamed of the weak cars they come out with
G0NEn60 said:As you stated thats an estimate. If this were true there's a couple reasons why. For one the 05 is supposed to launch better, hence the lower 0-60. The Cobra motor that you are bringing into question has the 4 valve heads that I would assume can breath better up top. Considering the fact that the 3v heads are the same exact part# as the truck motor it came off of, I would assume the 4v has better flow characteristics. I don't know what the actuall redline is, but looking at the dash pictures, its around 6 grand. I'm not to knowledgeable about stangs, but doesn't the 4v rev to like 7 grand or somewhere a lot higher than the GT motors. Plus, I would expect that the dual cam setup would allow Ford to tune for a much broader power band. Where as the single cam is limited to making power in a smaller rpm range. They might put out the similar numbers but as everyone knows its the power under the curve that makes the difference. Not to mention there's supposed to be a slight weight increase in the 05. Once again these are just estimates and we'll see the truth when it drops. However i don't expect the car to run too much better than 13.9's.

kirkyg said:I can promise you that the mustang engine will put out alot more power than the 3valve truck. If for only one reason the intake will flow ALOT more then the trucks. Ford has always used choked off intakes on the truck engines to produce more torque and less peak power because its a truck thats used mostly for pulling trailer weight and payload.

SVTdriver said:While we do not have a dyno to show what the power curve looks like. The point where the gt makes peak power is within 50 rpm for hp. And tq is made 300 rpm sooner. And while the talk about the weight increase maybe have some validity. The estimate so far is actually lighter by 25 lbs than the cobra I compared it to.
