Just wondering if anyone has race a 1999 or a 2001 Cobra yet...what were the details.

never seen it happen, but they can run low to mid 13's, and can trap as high as 105, I would say from 0-100 it could be close, but after that the 4V shines, 320HP and 7,000RPM's can be hard to beat.

AKAkracker247

Yeah that's why I asked the details. Haha

I would like too in my 4 door.... But i raced a bunch when i had my 01 SS @ the track..and yea they were mid to high 13 second cars with traps around 102-103 mph stock, thats if they had their lack of hp TSB taken care off at the dealer

I used to have a 99 Cobra. I used to run 13.6-13.7 at 103-104 all day long and the car was stock. The wheel hop was killing me when launching, but the car has a crazy 2nd gear which make for the launch. I used to race stock LS1's from a 40mph(2nd gear) roll to 110-120mph and win sometimes. So the 99 01 cobra isnt comparable with the 350Z. The GT is a closer performer than the Cobra to the 350Z.

I'd say it would be a driver's race until 80 or so, about the same as it is w/ an LS1. My brother beats pre-'03 Cobras in his TA WS-6, and when we race we are even until around 70 or 80 then he just walks away from me.

Race a Cobra? no... not yet... had a few opportunities that I have passed on.

Some of us were taught not to play with fire!

Well for a 99 Cobra it could depend on the car.
A few 99's had compression problems, and were overrated from the factory.

I was able to barely beat a 99 Cobra that presumably was one of the ones with problems, and my Z28 should be neck and neck with a well driven 350Z.

As for a 2001 Cobra...after the launch the Cobra should slowly start walking the Z, and then faster from about 70mph on.
A 350Z could win, but they would have to have a much better launch.

Also from what I have read the 03 Mustang Mach 1 is very much like the 01 Cobra powerwise (even though its rated 15hp less).
Its pretty much got the same motor.

I passed a newer (don't know the year) Cobra twice in one run session at Texas World Speedway this weekend. And, no matter where he was on the grid, I would always catch him and pass him.

I'm sure it's a fast car in a straight line. But, the one time we were on the front straight together, he waved me past and did not want to race me to the end of the straight. I even have a picture of this.

I'm not saying my Z is faster.... just that the Cobra driver did not seem to confident in his car, especially when he had to turn left or right!

Good car in a straight line, not so good on a 2.9 mile road course with 15 turns and only two straights. In the right hands, the car should be a lot faster on a road course.

This is half true...from what I remember...Ford did over rate these cars. However they tried to take care of it with (and anyone correct me if they can show me something different) "the fix" which I believe was opening up the exhaust, intake and a tweak of the ODB system. I don't ever remember hearing anyone complain about the compression. But again, feel free to correct me if I am wrong.

Correct. The Mach1 is what the 99-01 Cobra should have been...if I'm not mistaken, it is in a nutshell the 03 motor with out the low compression pistons and I don't believe it has the forged crank or Manley Rods...but again, someone please correct me if I am wrong.

I ran both a 99-01 Cobra and a G35 coupe of a 350Z both at the same time one night from about 70 mph till about 130.
Not trying to start a fight, but the Z/G35 was walked on pretty easy by the 99/01 Cobra...and I pretty much cannibalized the 99/01. I hate to do that to another Mustang....but, ya know...I got over it real quick

In 99 SVT advertised the hp rating for the Cobra at 320hp. As soon as the magazines started testing the car they started questioning the hp rating. Since the car was no faster than the 96-98 Cobra. Owners started taking their cars to the dyno and finding out the car was not putting out the advertised hp. Ford SVT knew they had a problem and to their credit started fixing the car.
The only reason the 99 Cobra had horsepower problems was because of a last minute change to the exhaust system because of gound clearance issues. Then on top of that Ford found out that the intake manifold had casting flask blocking the flow of air in the intake. SVT took care of these problems with the infamous fix. The fix consisted of new catback system, Extrude Honed intake and a reflash of the EEC-V computer. Some of the Cobra's without "the fix" were running anywhere from a low of 240-265 rwhp. I didn't get my car dyno before "the fix" but after the fix the car dyno at 286 rwhp. Which took it to a 13.5@104 mph and that was when the car was stock.

Yea that 2nd gear is crazy, it pulls hard all the way to past 80mph!!! My buddie has a modded 01 and it runs 12's, it has just gears, mufflers, and a x-pipe, they are very quick cars, just can be a ***** with the IRS!!!

AKAkracker247

Yup...these are some fast mustangs...

LSs1Power

Well Said. I got mine before the fix and it dyno'd somewhere in the 250's rwhp and 260's rwtq. After few months SVT sent us letters saying that they are going to fix our cars. Before the fix i was hardly walking mustang GT's running around 13.9 at 100-101 and after the fix i was playing with some LS1's and sometime win(look in sig for Cobra dyno numbers after fix). So they did a good job on the motor, but the T45 tranny, rear wheels getting seperated(I was going to die once) is what made me sue FORD for my money back and i got it .

Pete,

Not even a justified comment, sorry. Do you know if it was that guy's first time out? First time in that car? I've passed cars on track that should have been faster than me, and been passed by cars I "should be faster than". And this:
only shows good common sense of the guy driving the cobra. I back off from anyone that "wants to race the straight" for my own safety. Trust me, an experienced driver will show you just how well the cobra will do on the open track. I've watched a 00R being passed by a miata on track. Open tracking is a driver skill event, and has nothing to do with the car's power, or ability to handle.

The 99 fix was lower intake (extrude hone/acid dip, blue or green dot on lower manifold), catback exhaust, and reflash the computer. There were no compression issues. The mach 1 has an aluminum 01 block, with marauder/aviator/03 cobra heads, with 10.5:1 compression. Average HP at the wheels I've seen is in the neighborhood of 275, yet another car Ford is 'underrating'.

Sorry if my first post on this board seems negative, but I really wanted to clear the air on the open tracking bit....

Just one more thing about the Mach 1. I've notice from dyno sheets i've seen that the Mach 1 is pulling down around the same rwhp as the Cobra but it puts down about 20 more rear wheel torque than the Cobra.

sn8kbit

No, the axle design really won't add or subtract power or tourqe. It's due more to the bump in compression, and different intake, which has (i believe) longer runners which was supposed to reduce HP, but have no effect on tq, so as not to beat previous cobra numbers. If you look at the "5.0 Cammer" motor Ford has out now, the 11:1 compression with more agressive cams and FR500 intake has better than 450 hp and tq...

My father just picked up a Mach 1, he's bringing it up next weekend to visit, and I can't wait to *ahem* test drive it...

Caswell

Not neccessarily true. 9 times out of 10 IRS eats up more power than a solid rear axle. The universal joints at each end of each driveshaft are the culprit.

Another example... strap a 2002 LS1 Corvette and a 2002 LS-1 f-car to a chassis dyno. Even though the Corvette has the benefit of a true dual exhaust the f-car will usually dyno slightly higher.

sn8kbit

Ok, agreed. But I think you're talking .xx percentage difference tho, I seriously doubt it'd be close to 20 ftlbs of tq. Weird, discussing mustang tech on a Z board....
