I attribute it to the majority of Ls1s having **** for a slave cylinder. Or maybe mustang drivers are just naturally more talented.

And if you listen you can hear the cobra get close to the revlimiter, which never happens to the vette. My point is that the cobra owner really knows how to get all the power out of his car and it appears the z06 owner does not.
How do you know the Cobra is close to the limiter? Do you know what the limiter is set at on FAsnakes car or what his (or any pullied Cobra's) powerband looks like?

haha and exactly how far was he from the rev limiter since you can hear that well?
it is called sarcasm

he seems close but there is no way to know with out diagnostics, but the limiter should be just shy of 6500 or so.

Cobras have a very flat torque curve due to the roots blower and a pretty high power peak due to the 4v motors like high rpms. And if you listened to it you could tell that it is close to the limiter. Some guys like to bump the limiter up because they still gain power all the way to the limiter.

I've owned a Cobra since 2004 and I can't tell you with any certainty what rpms FAsnakes was shifting at........I'm pretty sure you can't either.

It's impossible for you to know whether he was "close to the limiter" or not since you don't know what he has his limiter set at.

but you can go off of sound when he does hit the limiter when he mis shifts. I was not getting all technical or trying to start an arguement just stating that it seems like he is getting all the power out of his car or close to it by getting high up there in the rpms. Just listen to it any you can tell the sound of the car changes with the higher the rpms just like every car. Its called deductive reasoning.

Like you said, we're sinking into the depths here. I will agree that FAsnakes certainly does get a lot out his car if his power #'s are accurate.

Since you brought that up... I will not get into the fact that Cobra's get heat soaked. Unless they stopped for a few minutes after each race the Cobra is making less power each run. I don't think the Cobra listed a heat exchanger as a mod, so that hurts even more.

Aerodynamically yes there isn't much difference, but a dig race and 40mph roll race are VERY different.

You were close to what I said all except for the part where you twisted it around to attempt to make it fit what you think I said. What I was "basically saying" was that the Corvette is more aerodynamic (with the lights down) than the Cobra. So the headlights being up shouldn't miraculously turn the corvette into a brick and the Cobra into a formula 1 car aerodynamically. While we're on the subject they were racing at NIGHT! Racing in itself is dangerous let alone racing in the dark 120+ mph with your lights off. Maybe the driver of the Cobra should have agreed to race up to, say 45 or 50 mph so the headlights being up wouldn't have created so much "DRAGGGG". [sarcasm] That would have been an awesome race!!!![/sarcasm] Maybe you should spend more time reading and less time trying to bust on people.

Someone should make a comp video of the Vets getting pulled. Some of the Vet would
They are both bad *** cars,but on that day the Cobra was faster.

I'm surprised by the results too, but for some to make excuses or call bs is dumb. There are a lot of variables that can cause different results. Should the ZO6 have won, I think so, but this time it didn't. Just for comparison, check out the vids in FAsnakes sig and then try to figure out why a ZO6 with 15whp more and less weight lost to a cobra heavier than the ones he beat in his C6. Like I said, **** happens.

Thanks for everyone that extended complements and enjoyed the vid... (we enjoyed making it)

But for the most part, IMHO, the cars looked pretty damn even. You would pull him hard, he would pull you hard. Back and forth, back and forth.
One 140# camera man switched between cars.

Who's ranger?
I'm going to lay low for now.. I know the recent vids speak differently but i'm not that big of a racer.

But eh, who cares... you should have a Whipple coming in soon, right?
Yea, she's coming soon, i'm just waiting on my installer to throw on the supporting mods..
After this last episode, my wife thinks my car is fast enough

30 - 40mph
Yea, my boys Z is pure sex..

None taken. I wasn't impressed with my driving that night, but it is what it is..

ranger it a guy who is good at driving vettes. I think he went a 10.8 with a bone stock down to the filter c6 z06 with nothing more then drag radials.

Never did I say, or act like it would make a miraculous difference. Just that it was an advantage that the vette could have given himself, but didn't.

Like I said "BEFORE," the two cars were plenty close enough to where either one of them could have seen fine from the other drivers lights. I have done it several times and never had a problem. If you don't like to, thats fine.

I state a fact of a race, and how it could have differed a little with a possible variable, and I'm busting on people.

Maybe you should spend a little more time reading as well. This subject has been dropped. You can stop beating the dead horse now.
