well aware... but I was under the impression that in the 1/4 mile the manuals did not have the time to accelerate through all 5 gears. Thats all I am saying. I swear I have seen guys say that they reach the higher RPM's in 4th but dont hit 5th. Basically the same way that the auto's trap in 3rd. Hence why halfcent's how-to on racing the auto tranny works cuz you dont need to get into 4th so you can keep the car in I

You need to open your mind a little more, you're not thinking about it correctly, lol

explain bro... what you mean?

I dont think I have seen anyone hit 5th in their cobalt on the drag strip. If someone has, say so. Every vid I have seen has them topping out in 4th... thats all I am saying.

Yeah, and when I do the quartermile, I trap at the VERY BOTTOM of 3rd gear, which means the manual has used almost two more full gears accelerating

If you are hitting 5th gear on a 1/4 mile track you have some seriously LOW gears or you did some really bad planning on the gearing for your car... just my 2 cents...

AUTOMATICS ARE FAR MORE EFFICIENT IN A 1/4 MILE. you will run consistent times more often. Most all bracket racers and econo dragsters use 2 speed powerglides.

Ok, well thats what I was saying... 99.9% of cobalts aren't hitting 5th gear on a 1/4 mile track.

what do you run in the 1/4?

this is not true at all get your facts straight before you spread lies. auto's are more consistant for bracket racing. but 99% of the time a car with the same work done to it, same hp, only difference being the manual tranny, the manual tranny will win. you can't compare a top fuel car that does 0-200 mph in 3 seconds to a base model cobalt. that's one of the most ignorant things i've ever heard.

fact of the matter is, take 2 cobalts, give them the exact same mods and exact same hp, with good drivers, the manual will win every single time. and you can't argue that, because it's a fact, not an opinion.

Hey, why dont you think before you talk.... How pissed would you get if some kid called your dad a fool?


That kinda talk does not add to the conversation AT ALL obviously there is a debate on the topic. So make a valid argument or move on.

Kev, are you taking into account a good tranny tuning? Technically if you are going to do the good driver mod on a manual, the reasonable equivalent would be a tranny tune.

I think its still a toss, a very good manual driver would be able to do some great things, but reality is, the driver is not as reliable and consistent as a computer.

Top dragsters are auto's because there is no reason to add additional variables to the equation. those drivers are good enough to hit their gear everytime... but why take the chance if you can have the perfection of a computer.

even with a tranny tune, the extra weight, extra drivetrain loss, and bad gearing on the automatic will not make up for the fraction of a second it will take for a good driver to shift.


look at the drag times, the auto's in the cobalt are about a 1/2 second behind. a good driver in a manual 2.2 can beat an auto 2.4, and we're talking about a difference of 25 hp and 10 tq. the auto's in the cobalt are just bad. if it came with a 5 or 6 speed auto with decent gearing, maybe that would be different.

lol, i wasnt trying to start an argument. how about a 300lbs dude in a manual and a tranny tuned auto with a 125lbs driver.





I think we got a race there.

Is it hurting anything to do this? If she isn't using the car, and i'm working on the jeep, I may drive the Cobalt for a week or so straight, shifting like this most of the time.


Sort of related question:
Also, one of my friends is putting a ShiftPlus kit on their 07' SS Sedan, and likes to do the same thing as me. Would it hurt his car to do that with the ShiftPlus on Mode1?
youre not really benefitting from it. When you drive an auto, it shifts through all the gears for you. Thats the point of them. Trying to manually shift an auto if anything will make it slower because the tranny takes time to adjust to the gear you switched it to, not to mention the increased chance of slippage. If you wanted to shift, should have gotten an manual. You could convert the tranny to manual, or electronic shift.

and you just do not know what you are talking about. learn something before again, like i said to other people in this thread. if you are going to make a point, back it up. blanket statements are pointless and useless.

No, not bitter, I have no manual envy. I enjoy my car. I am simply making the point that the post like yours and the other guy who ragged on some guys dad. It is ignorant to have a blanket statement like automatics suck. You made no valid point except to flame on people who have auto's. that.. is trolling.
