You don't think a factory Cobra that traps 113mph at sea level can't go out to MIR or ATCO in say -1800 DA conditions and trap 115mph? How do you think C6Zs trap 125-126mph at sea level with a great driver, yet in -DA conditions @ MIR or ATCO Jamie and Ranger will trap 128-129mph?
Actually Evan ran a 12.43 @ 113mph. But I'm digging deeper to learn more. A 50 degree day at Byron is sub-zero DA as well.
The C6Z is a lighter, more aerodynamic car with different gearing and more power. The discrepancy would be greater with such a car as well.

Much faster times have come out of atco or MIR, when Jamie made his run for example it was -1800DA, despite the actual track prep itself you will not get those kind of conditions at byron or GLD. The 12.43 was the quickest ET, not the fastest trap.

That has nothing to do with it, better conditions = faster times...Period.

It has everything to do with how the car responds vs. another. Conditions = more horsepower = greater benefit to the lighter, more aerodynamic car.
It benefits any car. Cobras are supercharged and LOVE mineshaft air, 1-2 mph in trap speeds in -1800DA conditions is not some huge unimaginable stretch.
Conditions = more horsepower in any car, the car that is lighter and more aerodynamic will preform equally better at sea level or well below. I'm willing to bet your Charger will trap 112-113mph if it was in those kind of conditions, but then of course you would have nothing to say.
I thought I would jump in here to join the conversation for myself. A couple of points from the race on Saturday. Density Altitude started out at 300' (before the Mustang gang even arrived), and that's when I ran my 13.129 @ 109.10. It climbed as high as 1066' by 4:30, and then dropped off to 738' by my last run against Tye's '05 modded GT at 5:25. I'm not sure that your mph would have been much higher with a better launch, but your ET would have been. Based on the passes I observed, you gave up a bit on launch. Your Cobra is sharp and quick, and you drive it pretty well. You definitely beat me in our race, but I would have only had you if you drove really badly. You might still beat my under better circumstances, we'll have to see ! Without a passenger and extra weight, and with 93 octane in my tank, I suspect your edge will be alot smaller. It must be interesting to have a 4150 lb race weight OHV sedan hanging with a more nimble Cobra! I can live with that. Once I get a tune and CAI, it will be a slightly different story, but that won't happen for awhile!
Forget the simple bolt-ons, go straight for the TVS 2300 supercharger!!! I would do a CAI, long tubes, and the TVS. 550 wheel is a piece of cake. With a cam the LS3s are doing 600+.
Mine will be 800 though

What I'm saying is 10 or 20hp for a 3100lb car with better aerodynamics will do more than in a 3600lb car. Would a powershift also gain more benefit from the lighter car as well? Less mass to move with the extra thrust.
Do a DA calculation at Byron on that day - I would be very curious. And Atco isn't the only track - Indiana, Florida, Sacramento - all depends on the day/driver. Actually being open when it's 40 degrees out is another story altogether.
Actually 113/114mph, since its been done already by others in various states. 400-410rwhp via tune, great air = 113/114mph.

And I'm saying a blown car can benefit from mineshaft air a lot as well. The differences I've seen are virtually the same, for EVERY CAR. Evolutions GT500, several ported eaton Cobras trapping 128-129mph at MIR and of course all the records held by C6Zs and even LS3 C6s are at those two tracks. There is no clear evidence of a C6Z being the only car that responds well in great conditions. It's no coincidence that those tracks hold the fastest times, it's a combination of very good air and a great track that's usually prepped well.

I believe it was around -300DA, no where close to -1200 to -1800 at MIR.

Prove it, I call BS, car must have been gutted, with slicks and a 50 shot of nitrous.

Of course every car benefits. But not only is there fundamental limit to the hp gained, but a stock Cobra won't benefit as much as the Z-06. Even if they both pick up 30hp, the Z-06 will end up with the better numbers at the big end. Surely you agree if 2 cars pick up 30hp, the one that weighs 500lbs less will have a greater benefit?
Btw, you can agree and still disagree on the 115mph trap speed.

I won't even justify that but I will say my neighbor with his Cobra found out the hard way. And mine is full weight, street tires and no nitrous, of course...

So an N/A SRT8 will but a supercharged Cobra that loves cold air won't? I'm going by numbers that I've seen, like I said all the fastest trapping Cobras are at Cecil, MIR and Atco. It seems to me they're benefiting at least 1-2mph trap speeds. Which is totally plausible, like I said, weather conditions are one thing, track conditions are another. Those 3 tracks are just "faster", all the records are broken there.

Sure it did, I bet it had nitrous, slicks and was gutted. I've never seen an SRT8 trap over 108mph, so by your logic I can call BS and say the car had "tricks" to go as fast as it did.

I'm not saying that. The tune for hp and shifting makes an enormous difference for the SRT-8. But that isn't what this is about.
So those are great tracks, but there are still no 115mph stock Cobras.

People have claimed it before on modularfords and others, like I said, it's the same exact thing as the times claimed by SRT cars or any other platform running 1-2mph better than anyone else has previously achieved.
Same thing as someone claiming they turned 115mph traps in a Cobra. There is NO difference whatsoever, I can call BS on every single one of those times like you like to call BS on Cobras & GT500s turning faster than average times. The only difference is it's not in a list, which means absolutely nothing.
Think about it though, people have put down 390rwhp STOCK in very cold weather with a factory freak. It's not some huge stretch here, 390rwhp, 3650lbs, amazing driver, well below -DA conditions and a little bit too much wheel spin causing a slightly slower ET but faster trap..
BTW, I'm not REMOTELY saying 115mph traps is average or obtainable by 99% of people racing a stock Cobra. Just like 129mph traps isn't obtainable by 99% of people racing a stock Z06 unless it's ridiculous conditions, at the fastest tracks in the country with great drivers. It goes for every single car out there, hell even the record for a stock VR4 was done by a 1st gen at MIR. Low 13s @ 107mph, the 1st gens made 20hp less than the 2nd gens with a 5spd instead of a 6. The 2gens ran 13.3s - 13.5s @ 105-106mph AT BEST. The guy just took advantage of amazing conditions and ran a time most people didn't think was possible. But I guess that's "impossible" too.
Anyways, I'm done. We've had this debate before, you like to call BS on everything unless it pertains to freak times posted by SRT cars.
The difference is they are repeatable and documented with multiple owners of modified cars. I would like to see any claim, link, timeslip, etc of a 115mph stock Cobra trap speed. Assuming it was done once, never to be repeated, it's not even worth mentioning because it isn't representative of the car.
And just like the 12.56 @ 111mph for a stock SRT-8 isn't worth using as an example, the 12.8s/12.9s @ 109-110mph are the reality on a great day.

It's been posted before, with a timeslip on modfords back in 03 or 04. Like I said, it's not IMPOSSIBLE nor does it mean the owners were lying. I'm simply explaining how a trap speed like that CAN happen, that's the extent of it. Extreme conditions, a bit too much wheel spin, a factory freak putting down almost 390rwhp at the wheels, a fast track and a driver powershifting the shit out of his car. No one here said it's representative of how all Cobras run in great conditions. 12.6s@113mph has been repeated by multiple owners, and that's what is used as an example of what's possible in great conditions, (that's not even counting Evan Smith's ET)..
