PLEASE YOUR SERIOUS ASSESSMENTS ONLY!!!!!

I drove a 06 XLR-V earlier and had the opportunity to test it's acceleration capabilities.

I had the opportunity to take a ride in one of these monsters today.

It had been "modified" slightly 4:11 gears (6 speed), chip, smaller supercharger pulley, larger airbox and performance mufflers via a Ford factory engineer.

It might be close BUT I think unless the XLR-V got some mods too the Cobra would win.

Of course the drivers are critical

Standby and Hans what do you guys think??

 

[1_XLR]

that could be close to 100HP of "slightly" mods!

the gear change is key though and would take the V from the line
.......then it's a matter of how long the race is


I'd like to here mswaims opinion on this one

O Boy, Who let the Cobra out of the basket?
My daughter who has extremely great driving abilities and has nothing but hot cars, took out a Cobra at Saleen's and then drove my XLR-V while racing me in Hans GTO. She said,
Hands down the V had more off the line, while the Saleen did nothing but burn rubber, the V sat down, front up and just goes.
Does the Mustang Cobra have a retractable hard top, navigation screen, stabilitrack, etc, etc, etc.
This is a matter of taste. if you want a fast car and that's all, there are many sports cars out there that can match up with the V.

These two cars are in different classes
Bob.............How about you Hans

Standby is absolutely correct. I am sure that most any Cadillac XLR or XLR-V owner could purchase a number of super fast cars but it is hard to compete with the enjoyment of driving an XLR. I thought that the XLR & XLR-V was really competing with luxury cars like Mercedes not Mustangs. Just my opinion.

Despite the probability that the Stang has more rear-wheel horsepower, I'm pretty sure the XLR handles what it has much better through the drive-train. Getting the power to the pavement is vital. I'm also not sure of the weight of the Ford... the number of lbs each hp has to carry is really all that matters; absolute hp means nothing.

 

[caddiedrummer]

I imagine the Mustang will take the V in most speed categories particularly in the quarter. But I don't care how fast you make it it is still a Mustang.


I have owned virtually every American sports car but never any version of a Mustang. None have ever looked like a sports car to me. If I want to smoke the Shelby I can easily do it in one of my Vipers. If I want speed, style and luxury I can only do it in my V. The Mustang /V debate is an apples/oranges deal.

 

[XLR I FL]

Yea maybe but the Shelby Stang is a soft top convertable. I agree totally about the luxery being "in our court". The rugs in the Stang look like outdoor carpet.

You didn't ask BUT as I understand it. The Cobras are limited production and the dealers are asking for and getting a $14-$15k premium for them. So $48 -$50k plus $15k is $65k. DON'T WE WISH OUR XLR'S WERE LIKE THAT!!!!

FWIW: My assessment is that the "V"comes with some surprises--aka Bob "Standby's" experiences. By that I mean fiddling with the traction control and I think using the totally automatic function would get you a near "heads up" race up to 100mph. The manual 6 speed seems to have a wider shift pattern than it needs for performance. So a automatic would get to the right gear at the right time and out perform a "speed adrenelen junkie" in the Stang.

After 100mph I'm really not interested (safety reasons) unless it's a place Bob picks out WITHOUT Helicopters!!!

IT'S FUN TO SPECULATE THOUGH!!!

Regards

Damn................that's real knowledge and support.
I didn't want to go bragging, but a cobra pulled along side me on an open stretch at a light, and I didn't see the Cobra tag on the fender. I guess he wanted to try me and I was thinking about presents and Rudolph.

He jumped out really fast, laying rubber in patches, and heard him explain as he drove out of sight, .............................................see ya at the next light.
When pulling along side him,I dropped in to neutral and rev'd it up high,
with a twinkling in his eye, I knew at a glance we where doomed to drop hammers as the light turned, we pranced.
There was a terrible screech from red Cobra's rubber,
a hood lifting high and the rear sitting down on my XLR-V.
It was over in seconds when I backed off at 80, a thumbs up came next from a gentleman, sportster
http://www.smileycentral.com/?partner=ZSzeb001_ZS Just for the record I jumped by 4 lengths, while he tried to get his sleigh under control.

Even Rudolph's nose was infra-red


Merry Christmas everyone and you to gentleman sportster.
Bob
Thank You Santa for my V , even if it was late last year.

Great Holiday yarn, standby.

As much as I like the look (and the price) of the new Shelby 500, I think it would have to work hard to run away from an XLR-V. I rode in one last month and I was very impressed with its upper-end power band, but from the line to 60 mph, my C6 will beat it. Even though it has 100 additional ponies, it has 600+ pounds to lug around. Last time I looked the XLR-V weighed in at 3800 +/- lbs and the Shelby is over 3,920 lbs.

Without knowing which Saleen Mustang Bob is using in his comparison, its hard to know what to think, however in round numbers both the 281 S/C and the new Extreme have more power and torque than the XLR-V and much lower rear gearing which is where the rubber really meets the road. If his daughter says the XLR-V is faster, then one must assume the XLR-V is unbeatable, no matter what car it takes on.

In my opinion, the two cars are so different you can't really compare them.

Here's a link to a Car and Driver side-by-side test of the C6 and the Shelby. Not the same as the XLR-V but the C6 beat it fairly easily.

Your right, I should have asked which engine was in the Saleen. Mr. Saleen probably puts a few engines in his re-fabricated vehicles.
If I where younger, MUCH YOUNGER, I would probably go with the Cobra having owned a 69 cobra 428 ram-air beast of a car with no traction. I put traction masters on it and it was a horrible ride, so I took them off and that's where I learned to take a car like that off in second gear and after about one revolution of the tires I would drop it back into 1st.
Love that commercial of the guy taking his car of the boat in Germany because he couldn't find a speed limit in American he liked. Kind of reminds me of Hans.

Reminds me of Hans, :lol that`s good Bob.

I`m in Dec. month not often here on the forum because it`s the hardest working - time of the year for me!
Nope, on no way you can comparision a Cobra to an V, this two are players in different leagues.

After re-reading the first post, I have to wonder just how many ponies that modified Shelby is producing. The aftermarket has been very kind to the Shelby, due in part to the fact the motor is not a new platform.

My guess would be something over 600 horses, more than ebough to compensate for ther weight difference betwenn the two cars.

There are numerous Shelby's out there (including one from Sacramento) with simple bolt-on parts running in mid 11 second 1/4 times. That is fast in anybody's book.

Whipple is already producing blowers that are a bolt-on replacement for the factory huffer. With the new 3.3 blower and chip the motor produces over 700 horses on pump gas.

I don't know about you, but I don't want to be the guy who ends up next time one of those beasts at a stop light.........................

 

[XLR I FL]

Yea he had the factory engineer do some "after work" mods on the car. I assume that the engineer knew what to do to correct some of the "weak spots" in the 500hp stock one.

My and the owners guess is that your estimate is near correct --maybe 550hp and with the 4:11 gearing the whole torque curve is VERY DIFFERENT. the smaller pulley on the blower makes for more "boost" of course so who knows all of that could put it in the 600hp range.

The 4:11 won't hurt TOO MUCH at top end since it is a 6 speed. But as Standby said the drivers ARE the difference!!

 

[mswaim]

Those 4:11 gears will hurt the top end, but off the line that thing should be a sling shot.

 

[Guest]

Yep!...........Can't wait to get blown off by one of these. I better be in Victorville, so I can do 158 and claim top honors with the short gears. I think I should have bought a Mustang, but where do they put the retractable top, nav sytem, etc, etc. First I have to send a big check to my lawyer for the ticket.

Those 4:11 gears will hurt the top end, but off the line that thing should be a sling shot.

This is some poor video and lousy camera worek but it gives you some idea of what the Shelby's are like. Now consider they are capable of an additional 200 horsepower with bolt-on parts............

This film sure does prove my point about a drivers ability and at some point, to much HP on street tires doesn't do anybody any good.
I like my V the way it is. I get every bit out of it without leaving half my tires behind me.
