what to think?

[white99cobra121]

I keep reading about these GT's and other (newer) cars that claim to be stock and beat up on cobras. I've got a 99 and havn't been a big racer but am wondering what's up? Is a GT or z28 faster than me? Just a question.
What can I supposedly beat?

[Fox Body]

A stock GT won't beat you unless you REALLY can't drive.

You'll have a little trouble with some Z28s (the LS1s). With some driving skill, you should win at least half the races against the LS1 Z28s ('98 and up), though.

You cannot put a set 1/4 mile time on cars b/c much depends on driver, etc. For example, let's just say Cobras and LS1 Z28s run a 1/4 mile ET range of 13.6 to 14.2. Some are even slower, some faster.

It does kinda piss me of when people with GTs, for example say stuff like "I can run 13s flat (that's 13.00) without ANY mods at all." It's NOT gonna happen.

thanks, this is my first "fast" car and I am still learning how to launch the thing. any tips on what I need to do to get best off the line or rolling starts?

[Lizard King]

Your 99 Cobra is faster than a 99-01 GT ... Motortrend says 0.1 seconds faster on the 1/4 mile and 0-60MPH. I think they are wusses, ... the difference should be more than that because you have 320HP (Stock) compared to 265HP on the GT. - identical torque -

The big thing about your car though is it can out handle just about any muscle car with it's independant rear supspension (which I hear is not so great for 1/4 mile launches)

Also, that DOHC engine of yours is just asking for add-ons... exaust, supercharger,...

You should be careful against any 98 or more GM 5.7L products... they run low 13s...

Got pics of your car?

thanks for the help, yeah, I got pics-am yet to post...soon to come

Unless your going to a track that spays "glue" or that you have drag radials, launch under 2000-2300rpm.

I take mine of the start at about 1500rpm... no wheel slips, no wallops, just damn fast.

BTW, anybody know why my signature image is not working?

You'll be faster w/o traction control and a lot practice. Cobras are hard to launch, there's a very fine line between bogging and spinning.

[dirtyGT]

YOU'LL probaly launch better at the strip because of the better surface but i've seen a few 99 cobras launch vilently with bad wheelhop so just be careful and pratice and don't worry about 99gt's unless there modded

I hate to say it, because I love cobras, but they aren't anywhere near 320 hp...they dyno(factory stock)250-260 rwhp, and that equates to about 295-300 bhp. The newer ones after the upgrades dynoed around 270-275 rwhp, not if they lost 17% in driveline, ets, then 275 would give you the full 320 bhp. Just a thought...

With street tires it's pretty tough to get a good launch. The few times I tried to race my '00 GT at Sears Point when it was stock, I would always bog or burn out off the line. This resulted in 14.2-14.4 second 1/4's at 98-99 mph. The mph indicates that it should go a few tenths quicker with a good launch.
Slicks or drag radials are the best way to get a good launch.

From what I've read, the Kenny Brown lowering springs nix the wheelhop problems that the IRS Cobra's have.

The 96-98 & 99(without fix) Cobra's dyno at about 260 at the wheels, they make the hp they are supposed to, and the last post on the fix dyno numbers I saw was 271 before 283 after. Which meant that Cobra was making closer to 340hp at the flywheel. The Cobra's with the fix do make the 320 they are supposed to. They have also been known to run in the mid 13's stock, real real low 13's with gears and DR's.

[SaleenGTS]

Not to start anything here, but since when do mustangs lose 20% from the flywheel to the wheels? Ever since I can remember they lost anywhere between 15-17%, but NEVER 20. If this car dynoed 383 rwhp, that would be about 330 bhp, which would be more than my est of 320(sorry guys my mistake) But the main issue here if I understand correctly is can he beat 99-01 GT's, Z's and SS's or WS-6's. GT's YES. Z28's, well that, as it has been already stated before, will pretty much be decided by the drivers. I have never seen a LS-1 dyno under 280 rwhp, most have been around 285-290(Z28's and T/A's ONLY, not WS-6's or SS's) They weigh about the same as the cobra, and lose about the same amount in the drivetrain. The WS-6's and SS's are pretty awesome as far as factory power from what I have personally seen and read. When I dynoed my car there was a local guy with a 2000 SS with a filter and flowmasters that dynoed 308 rwhp. He said his factory setup dyno was 298, and I believe it. So say they only lose 15%, then a factory SS would run about 340 bhp, so you would have to be an awesome driver to take down a ram air foe given he is a good driver. Just my opinion though, to each his own...

The information I've always read was equipped with the T-5 about 17%, C-4 about 19%, and the AOD about 22%.

[SaleenGTS]

I'll say that is a happy medium, and agree with you there , but his Cobra isn't an Auto...is it? I don't remember him saying that or if they even came AOD??

[white99cobra121]

no, it's a 5 spd...thanks for your help

[smooth]

the loss is not percentage based. the tranny takes a fixed amount of hp at a given rpm, same with the rear. cobras make the hp they are supposed to. no one knows for certain how much hp the IRS saps. i've never seen any 96-98 pull below 260rw sae corrected in a good tune.
