yes you are,look at the 60' time,you should know better. I went out and found the slip. my friends 96 Cobra weighs in at 3540 with him in it (220 of it him). thats including jack and spare. and from what i have seen, the 96-98 cobra usually puts down about 260- 265 vs. 220-230ish for the GT stock.

 

But what will a Cobra run with your limited mods:

K&N, !silencer, pulleys, synthetic oils.

You are probably running 1-2 mph faster than stock going by Mikie's trap speeds.

 

Most on this board will agree that a '99 GT vs. an LT1 is a driver's race. And Marisso says a '96 Cobra will beat a '99 GT by 3 or 4 tenths. Then will a '96 Cobra beat an LT1 by 3 or 4 tenths? No it won't. I still say a '99 GT 5M hardtop is about equal to a '96-98 Cobra 5M hardtop and an LT1 6M hardtop in 1/4 mile e.t.s.

 

Probably 1-2 mph and 2-3 tenths faster than it did when stock.

 

The LT1 vs. GT is a drivers race,yes,but the LT1 will still win given equal drivers.Stock M6 LT1's trap about 2MPH higher than stock 5m GT's (98-99 vs. 100-101) so yes its a drivers race but the Cobra runs closer to 103MPH which is only really 2MPH's or so faster than an M6 LT1 which isnt TOO noticeable but compared to a 99+ GT the differences add up. Just cuz the GT vs. LT1 is a drivers race doesnt make them equal. If you still say the 99GT is equal to a 96-98 Cobra then you're being ignorant.

 

Here you are giving an average trap speed for a '99 GT and higher than average trap speeds for LT1s and Cobras. All 3 cars have very close power to weight ratios. The LT1 and Cobra have better power to aero drag ratios than the GT but this does not hurt the GT much until high speeds. The '99 GT has about 230 rwhp and weighs about 3250 lbs. The LT1 and Cobra both have about 258 rwhp and weigh about 3400-3450 lbs. So the LT1 and Cobra have a better power to weight ratio, but just barely. The overall gearing is better in the GT than the LT1 in 1st and 2nd gears. The GT has a lower rpm powerband than the Cobra so it has better gearing suited to its powerband. From what I have seen these three cars are all very close to each other in a 1/4 mile drag race. Heck, throw in the 350z and SRT-4 too. All 5 are very close in the 1/4 mile.

 

if you think a car that has 45 more HP and only weighs about 50 more lbs. (I posted earlier about the cobra weighed in at 3320) comes down to a drivers race, then your looking to race some really bad drivers. Ill leave it at that.

 

45 HP rated difference. Really about 25 rwhp difference and most of that is way up in the power band where most owners of these cars are afraid to go. Also, the Cobra weighs about 150 lbs. more. GT about 3240 lbs. http://www.edmunds.com/used/2000/for...denav..6.Ford* 0-60 5.5 sec. Cobra about 3390 lbs. http://www.edmunds.com/used/1998/for...denav..6.Ford* 0-60 5.4 sec. It takes a long time to get to the power band in a stock geared Cobra in 1st gear unless the driver is slipping the clutch at a high rpm perfectly off the line.

 

unless stock 99+ GT's are dynoing closer to 250RWHP then your math is way off. Actually the HP rating was very accurate for both the Cobra and GT.Dont worry so much about dyno numbers anyways,go to the track thats where the real numbers count. GT trap speed-98-99 Cobra 103.

GT=

BTW. My friend never had a problem getting off the line after 1 day of owning his 98 Cobra.Now after gears cutouts and pullies hes runnin 107+

 

Stock '99 GT 5M dyno about 230 rwhp. Stock '98 Cobras dyno about 255 rwhp. My math is right on. Stock GTs trap about 99 on average. Stock '96-98 Cobras trap about 101 on average.

 

stock Cobras Trap at LEAST 102.5's (and thats on the lowend of the spectrum)and dyno closer to 265RWHP.

just face the facts the GT gets its alright get over it.

 

Yeah, on average they trap at least 102.5 stock . They dyno about 253 rwhp on average. You've more than earned a big fat

 

Actually you are both sort of right, the 96-97 are around 255 rwhp while the 98's got a better computer program and dyno about 265 to the wheels.

 

I'm a little confused and maybe you can help clarify this for me. I'm not flaming here and I admit up front I know very little about Cobras so please help me understand this better. I was always under the impression (from what I have read) that stock LS1's run better then stock 99-01 Cobras. Now your telling me that it's the other way around. Stock 99-01 cobras run better ET's and equal or better traps then 98+ LS1's. Now what I want to know is how?

Mustang guys here have said the 99-01 cobra dynos 255-265 rwhp. The 99+ LS1's are anywhere from 280-320 rwhp but lets say 295 for the basis of my question. So if a LS1 dynos with 30-40 more rwhp then the cobra then how does it trap a mph less and et's a few tenths higher. Is it the weight of the mustangs? Gears?

When you hear 100 people all say stock 99 LS1's beat stock 99 cobras you tend to believe it. Your the first person I have ever read claiming the opposite that a standard stock LS1 can not beat a pre 03 cobra.

BTW the only way I could believe your 40mph roll story is if the ss was a automatic. 40mph catches him in a dead spot and out of his powerband as I all to well know with a 3.23 auto myself. Try that same race from a 60mph roll and you may see a very different outcome. Or drop it down to 25-30 mph and run em again as that is a nice sweet spot as well on the A4 LS1. But 31-45 is a dreadful spot to race from a roll in if your a LS1 auto with stock torque converter.

 

Darren....you are correct on some info and incorrect on some info.

Everything being equal, 98+ LS1 Fbody's are indeed quicker (on average) than 99/01 Cobras. That doesn't mean that stock for stock, a 99/01 Cobra can't beat the LS1, but that is the exception rather than the rule.

99/01 Cobras dyno 275-280 RWHP in stock trim vice the 255-265 that you cite. Those numbers are more along the lines of the 96-98 DOHC Cobras.

Someone brought up weights of Cobras a bit earlier. My 98 weighed 3495 lbs w/me, making it ~3310 lbs w/o me. My 99 Cobra weighed 3575 w/me, making it ~3390 lbs w/o me.
