5 or 6 speed Tranny

[crj_lll]

I am wondering which would be faster in the 1/4 mile. I woudl think a 5 speed would be faster than a 6 speed because less gear shuifts to get to the same speed. What does everyone else think???

[flylwsi]

it has nothing to do with the number of gears.
it has to do with the ratios.

in the 1/4, you're not going to use all your gears anyways...

6 spds have closer ratios, meaning you stay more in the power band, but it depends on the power band of your car.

it's more than just the number of gears.

[crj_lll]

You seem to be misunderstanding everything I post today. The more you shift, the less you are accelerating. In my opinion, 4 speeds are faster than 5 speeds. That would logically mean 5 speeds are faster than 6 speeds. But since I have never driven one, I was asking the opinion of those who have. I know all gearing is designed to keep the acceleration in the power band. That is not my question.:smoka:

[flylwsi]

again, you're wrong.

if you're running a trans with closer gearing (ie 6 spd), you can keep the motor in the power band, instead of dropping lower in the band, and having to come back up.

the number of shifts is irrelevant.

you're not using all 6 in the 1/4 anyways.

in my car, i was shifting into 4th just after crossing the 1/4 line.

so i only used 3 gears.

and it has everything to do with gearing and not the number of gears.

i know what i'm talking about, thanks.

[flylwsi]

and...
if a 4 spd is faster than 5 spd... in your opinion...

why is that so?

gearing.
different gearing in a 4 spd vs the 5 spd vs the 6spd.

I have read some of your posts in the past. You like to argue. I am not asking about gearing or power band so all of your comments are irrelevant. I am asking about dirvability. I agree with evetrythin you have said, shame it does not apply to my question. Maybe you have a different car than the rest of us, but when I push the clutch in, then engin stops pulling the car forward. If I am racing and a guy does that more than I do, I should logically beat him. That is the basis for my question. NOTHING TO DO WITH GEARING OR POWER BAND:smoka:

[flylwsi]

nope.

if he's got better gearing than you, he uses his power band better. stays in it more.
it has everything to do with gearing, and nothing to do with the number of gear changes.

i don't like to argue.
but i like to prove my point.

the number of gear changes is worth, oh, something like hundreths of a second over your 1/4 mile, especially with 3-4 shifts at most.

if someone is tenths of a second faster than you, it's not going to make a difference if he has 1 more shift than you.

if they shift poorly, yes, they could lose, even in a faster car.

if that's your question, yes, they would lose b/c you're shifting faster.

but if the car is faster overall, then the amount of time it takes for your total number of shifts is irrelevant...

my point in regards to gearing is this...

if you've got a 5 speed with longer gears that drops your RPM's back down under the strong part of your power band, then it takes longer to get back up, compared to a closer ratio 6 spd that puts your revs right back into the power... so they're faster coming off the shift...

[flylwsi]

i saw a comparo with the vw 5 spd in a stock jetta, vs a modded jetta, vs a jetta with a sequential trans in it...

there were quicker shifts in the sequential, but it still had more gears...

(for the sake of arguement, lets say all three were 5 spds)

since the sequential is considerably quicker in it's shifts, it would cut time from the overall 1/4 time... minimal, but it would...

however...

the sequential was a 6 spd, and still much quicker...

so it's in how fast you shift, and the ratios...

when you shift also plays in, b/c if you shift early, your rpm's drop lower in the power band...

so... the number of gears is less of a factor...

which is my point, which is the answer to your question.

SO... IN SHORT...

it's not just the number of gears, or the speed of the shift, but it's also gearing, shift rpm, etc.

consider also that most fwd drag cars are 5 spd... some use sequential 6 spds...

do they see all these gears?
most likely never, unless they're geared to give ridiculous acceleration with no driveability...

[flylwsi]

one more thing, and then i'm done...

ask this in other forums here as well... see what replies you get...

different forums than the honda board (such as the "car comparisons" or "technical" or "street racing" or "drag racing" forum)

flylwsi, your are completely right. the guy is just ignorant and doesnt understand what ur trying to say. he seems to think it takes 5 seconds a shift or something. shifting from one gear to another doesnt take that long if you can shift fast enough. thats what crj is stuck on, the time between shifts, but they arent even long enough to be considered a factor.

[KrNxRaCer00]

i don't understand ppl like this...as long as ur not taking 2 seconds to get from gear to gear...its like flyw said...its all about the ratio, the number has very little, if ANY differences in 1/4 mile time...crjIII he answered ur question...ur jus thinking in the wrong way. ONE LAST TIME...5/6 GEARS DOESN'T MATTER (yes even tho u shift more, if ur quick, its not going to matter) ITS ALL ABOUT HOW THE GEARS ARE SET UP...GET IT THROUGH UR HEAD.

[crj_lll]

Thank you for your useless comments. I got my answer from someone else. They were not hung up on gear ratios and were able to think put pf the box for 2 seconds. I will build my custom tranny with the information I found. Just incase you are wobndering, it will be a 5 speed, but not for any of the reason you all stated. Maybe one day you guys will learn to try to listen because not one of you still understands what I was asking. You answered a ratio question. I knew that information already. My question was sinmple and did not require all that other garbage you guys gave. So have fun online, I am off to build something different. :smoka:

[flylwsi]

hey dumbass.

it has everything to do with gears.

that's why you're getting a custom trans?
b/c you get to pick the gearing.

what don't you get ?

your skull is hella thick my friend.

it's got everything to do with gearing and nothing to do with numbers.

get over it.

you're getting a tranny other than stock b/c the stock one doesn't have the right ratios to work the way you want.

all 5 spds are not geared the same.

that's why you could conceivably get different times from 2 different trannies on the same motor in the same car.

what don't you get?

[crj_lll]

Actually, dumb ass, I was choosing between a 5 and 6 gear tranny and according to your dumb ass self, I should have takenthe 6 speed because the ratios are closer together and will keep my engin in the power band more efficiently. But since I understand your answers but they still do not apply, I have chosen the 5 speed tranny, So dumbass, you still do nto understand the questiopn and I doubt you ever will. This is my last reply because you have to be right so you can think you are but your infomation was useless to the person who started this question, me. As I said before, I got the answer from a person who obviously knows alot more about trannies than anyone on here.

[flylwsi]

i didn't say the 6 spd was better.

i said it depends on the gearing.
which is what matters.

get it through your head.

a 5 spd has gear ratios further apart, but it depends on the ratios.

you could have a 5 spd with better speed, simply b/c the motor has a power band that works better with those ratios.

some cars power bands work better with tighter gears, such as a 6 spd would have.

you chose the 5 spd b/c the gearing was better than the 6spd you were looking at.

does that make sense yet?
