Okay so we all know that manuals are faster than autos, obviously taking about transmissions here. Now I was going through some of my old car magazines the other day when I found an article in HOT 4s where they wanted proof of this. What they did was dyno auto cars then do a gearbox conversion and dyno the same car in manual, the results were pretty significant-around 10% power increase for example they did a skyline dynoed auot was 218kw at the wheels, converted it the manual and it dynoed 240kw at the wheels. This just is evidence to the fact that manuals are faster than autos.

Now the question I want to ask is lets say we have two cars that pull 140kw atw, same weight, torque and blah blah. One is a manual and ones an auto. Now what will win a drag between them?

Just weird questions that I'm pondering

There are too many variables to match.. just because they both have a peak power of 140kW ATW doesn't mean that they have the same power curve. One of the cars might have a flatter torque curve so it is producing more power sooner than the other car..

but if you assume that you just have two cars with identical power and torque curve shapes and identical gearing so that at any given RPM point they are producing exactly the same power at the wheels, and both cars have the same drag coefficient, and both drivers had an identical launch.. then they would probably come a dead heat.

assuming everything is equal as has been said...
i'm acutally going to guess the auto would get through a little quicker as the manual would be more prone to errors and a good auto shouldnt have any drops in torque so should keep powering on while even a well driven manual changes gear...

Actually - two of the same cars with 140kw ATW cannot have the same torque levels.

for an auto to get this power to the ground they need more power at the fly!!

I still would say that the manual would win - but it depends on the drivers - small mistakes can cost it!!

Manual

If all things being the same, I'd still say the manual will win. There is more control over gear changes and if the driver knows how to change gears then the revving out just that little bit more will put it ahead.

Even with the same gear ratios, manual will still outrun the auto... due to the time to change gear and the torque convertor.

and if you dont change 'granny' style like me, then your sure to win :lol: 8)

[no, this wasnt a open door to start baggin me :P ]

yes it is

hahah booya changes gears like my grandma and she doesnt drive!





wish i had a manual magna :cry:

Wouldnt an auto get off the line quicker therefore giving it a headstart?

Just stall it up and let her rip.

or if you have low down torque like a 3.5L magna, just stamp the loud pedal and your off. :D

manual drivers i reckon would have way more trouble getting off the line, especially in a front driver.

Using tpitronic mode (quick shift) an auto would win...no human error and faster changes....sorry guys....just my opiioion and experiance... 8)

Considering 140kW would probably be at the fly, you have to remember that an auto has much more power loss.

The manual will win with the right driver, tiptronic is still slow.

And anyway, this is completely hypothetical as it's impossible to actually happen. They will never be the same.

when i wrote this i said 140kw atw

Oh sorry I forgot.

But anyway what I said after that still stands...It's completely hypothetical.
And to be honest it's a kinda pointless argument.

having used tiptronic i would have to disagree with that. sorry i own a tiptronic but it has honestly kept me back. in my tr im prity quick at changing gears even without a short shifter.

perhaps i just havent got use to timing the gears properly but meh. Who was it on the booya cruise who suggested relocating the tiptronic to buttons on the steering column?

*cough* Its worth a try.. *cough*
Time to meet up with 2 Magna Drivers.. 1 Manual and 1 Auto.. Must be stock as a rock and must both be of the same series. Even then variables and yada yada yada.. I get the picture.. Still wouldn't mind seeing what happens between the 2.. if anyone is game.. Just to inform you.. I aint.. :P

SuFz :evil:

Its nice in theory, but you wont get a manual and an auto that are both 140kw atw and the same torque curves etc. Hence why I said this is a pointless argument

And then swap cars for another run or two.

Killbilly had to shoot down the fun.. I stated that the variables and yada yada would come in the way.. but no..You still had to shoot down the idea.. SAD.. Just sad.. :roll:
Later

SuFz :evil:

lol what!?

You stated that variables would come in the way...

I'm agreeing!

I also said that the situation is extremely improbable (bordering on impossible) and therefore isn't going to do anything useful by discussing it. Really, it's only going to cause an argument.

Anyway, no need to hack on me because I brought a little bit of reality to the conversation!

And seeing as though it's pointless and it's only going to cause an argument, I feel I should stop it now before it does that.
