Manually shifting an auto. Ok to do often?
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

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
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.

I dont believe its a good thing, my dad always used to give my brother **** about it. He used to be a Master Tech at AAMCO years ago. Something about bearings and oil, bla bla who listens when your getting bitched at. At any rate, I dont think its a good common practice.
what do you run in the 1/4?
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.
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.
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.

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.

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.
Hey guys, I usually DD my jeep, which is a five speed. When I drive my sisters Cobalt (07' SS Sedan, Auto) I like to shift it from L --> I --> D manually.
Also, when slowing down to a stop, i downshift it from D --> I --> L
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?

thanks for clearing that up a little... i guess i dont know how to word things correctly.
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.

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.

Makes me so happy
Like i said bitter
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.
How am I rude or an idiot?
