Was comin home from work on US.1 tonight and up ahead I see a newer cobra and a girl is driving it. I start talking to her she stated that the car run low 13's in the 1/4 mile, So I say lets hit it at 25mph now the street is full of cars but I would like to see what would happen. We are dead even until my car shifts to 2nd and slowly I can tell she is pullin and we stop around 55. My question is that do manual cars usually win in roll racing vs automatic cars? I think I could have Won the race if it was from a dead stop in the 1/4 mile.

if she was stock you might have a pretty good chance, modified cobras = a quick and painful death for stock or lightly modified f and y bodies...

If shes running low 13s like she says, you should have gone from a dig, I think you would have got her. And yes, going from a roll is a big advantage for a manual.

A stick has more gears and has it better from a roll most of the time IMO.

Ex. I raced a tuned and exhaust 6.0 newer GTO and he had a stick. From 2 different rolls around 35 and 30 he stayed even and even pulled a bit at first.

Well we are at a stop light and I suggest when it turns green we go. I pulled hard and had close to a car by 40 and when my car shifted from 1st to 2nd I pulled a good car and by 80 I had 3 cars.


So, yes I think a stick can have an advantage from a roll with a auto.

Normally yes,but with the right convertor it is not so.
I have a Yank PT4000 ,racing from a roll verses a M6 has not been a problem YET.(always can find a faster car. But not my point)

Thanks for the input guys, It was dead even from 25mph on, then when the car shifted into 2nd the cobra started pulling slightly and I think they are rated at what? 380 hp. Like I said if it was from a dig I should of had her.Because, I beat a 2005 GTO rated 400hp from a dig and had at least 1 1/2 cars infrom of him from 0 to about 60 mph.

Though question, and the answer is - yes, no and maybe.

A Manual in the Fbody's case has 6 gears, and each ratio is shorter allowing better in gear accelaration. However this means the terminal speed in each gear is lower so more time is spent shifting. Shifting costs time.

Also, with a manual as it uses a clutch the drive is not very progressisve so from a low speed roll it is very easy to light up the tyres.

With an auto you have the downside of the longer gear, however you can run to a higher speed in each gear and the car will continue to accelarate during the shift. Another downer is if you are in D/3rd at 30mph when you hammer it you will have to wait for the box to kick down, you do not have this issue with a manual. An aftermarket stall should over come this however.

With an auto for roll racing you really want to have a wider spread of power as you will spend more time in the lower rpms. So a well setup auto (in terms of power, tune and gearing) has a very good chance in a roll race.

If you are talking stock vs stock then as long as they can drive the manual has the advantage. Especially in a Cobra, as it has plenty of power, gob loads of torque and pretty sensible gearing.

Good point. Thanks

Sometimes I over look the obvious because I am not using it.


I think I need to get that TC, maybe a 3200 Yank....

Im wondering after 100mph if you would have started pulling on her? How are Cobras up high?

Does anybody know how cobras are up top, maybe I could of Took Her. I know off the line with the converter I would of had at least 2 cars infront of her,but traffic was crazy. We rolled from 25mph which is supposed to be a sweet spot for automatics. like I said when my car hit 2nd she was gradually pullin from me, but that wasn't from a dead stop, where I could have owned her at the time. Maybe next time, I see her on the street its off for bragging rights ha ha. Actually, brieflly talking to her she had some modding done not a pulley but she said low 13's at 109 mph.

Thats not modding, thats basicly stock. 03 Cobras are pretty quick.

03/04 Cobra's are underrated at 390/390 from the factory. Mine was about 425/400 assuming 15% loss when I dyno'd it new. Cobras pull 3rd gear (80+ mph) very very hard.

the manual owns from a roll (downshifting)

go from a dig if you have Nitto's and run under a 1/2 mile you should be good to go with a stock 03.

the cobras pull hard in 2nd, 3rd, and 4th. the stock 3.55 are pretty good gears.

going for a roll with a 3200 stall youre going to get owned bad unless you have a lower STR converter (nothing bigger than 2.0).

Depending on where you live, my buddie could show you just how hard they pull!

I ran a stock 04 Cobra 4 times(3 at the track, 1 street[roll]) and killed him pretty good w/mods in sig.

TORNATIC!!

I read in one mag where they said the '03/04 Cobra was like a freight train all the way to it's max speed.

Being a manual,it's all about driver ability.
The car has plenty of power and potential,but still needs to be driven to prove it.

I raced a 03 Cobra with only a CAI for mods and from a 75 mph (highway) roll
first run i sprayed him with a 100 shot and totally killed him.
Was 2 or more cars ahead by 100.

Went a 2nd time ,me without spray at same speeds and still put more than a car between us by 100. Now should that have happened,who knows.
With my 4000 rpm stall the power is always there and the shift extension is awsome,only drops to maybe 5400 shifting at 6000.
We pulled off the highway at the next off ramp and bs'd for a few.
Dude told me his girlfriend told him to get the Camaro when they saw me up ahead on the highway.
He also said he never has been beat in this car till now.
I really think he needed a little more time learing to drive it ,but nice guy and really attractive girlfriend.

She told me my car sounded awsome and took off like a jet. Hearing that from her was better than beating the Cobra,to me anyway.

LS1 A4 with 4000 stall,3:42 gears,Lt's,Borla,lid and a little spray to top it off is a whole lot of fun(IMHO anyway).
A4's are not near as bad from a roll as some people would like to think.

Thanks for the replys, Well with the current Mods I have now I know what to do next time,Next time is goin to be from a Dig. 3200 Stall is enough from a dig to get me goin for a kill.
