The gear ratio causes the 6spd to have a lower top end than the 5spd
Is that true?

 

Do you mean 5th gear? That's usually true for most cars, their highest attainable speeds aren't in the highest gear.

 

2K2 only comes with a 4 speed auto or a 6 speed manual. There is no 5 speed transmission. Please clarify.

 

he probably means the 2k2 with the 6sp

 

Likely, top speed will occur in the 5th gear of the new 6 speed.... pretty normal, 6th gear is very high. I assume thats what he's talking about. Unless, your talking Altima to Maxima

 

I know very little about rice juice aka NOS, ZEX, N20 etc..

Say you used a 100shot (assuming all precations and upgrades made) and you hit top speed and redline in 5th? When shifting to 6th would the car pull at all with the 100shot over and above the top speed of 5th?

 

Hey 20th maxstyle, it would not make sense, to have the 5th gear having higher top end than the 6 speeds, even if your talking about 5 spd 2K1 versus a 6 spd 2K2, the 2K2 have a bit more power, technically the 6spd should defenitely have a higher top speed than a 2K1 5spd, but maybe I need to recycle and go back to school.

It all depends on gear ratio and the torque curve and technical stuff like that. the 6sp is a "close ratio" what ever that means, so that means the gears are closer in ratio. Like the 00 and 01 5 sp gears are not close enough? each shift is a drop in 500 rpms, I don't think you'll get any closer than that. I wish I had a 6th gear for highway driving, save some more gas. Maybe that's what the 02 SE 6speed has, an even taller ratio for the top gear which means it will give less torque... won't pull as hard as the 5th gear on the 00-01.

 

You're reference of NOS as "rice juice" shows your ingnorance on the subject. Just as many domestic performance cars use NOS as imports. Go to a NHRA drag race event and start calling NOS "rice juice" and see how many guys beat your a$$.

About your question....yes the car would probably pull becuase of the excess power to the wheels vs. stock.

 

That would to be expected with the .69 (or something like that) 6th gear. You would need alot more power to drive that top gear to redline. Most of the 6th speeds out there are to give us a decent overdrive gear (which I think is still not tall enough, it should be .60 - .55) while giving us better perrformance because the 1-5 is tighter.

DoubleA, your argument lacks the insight into wind resistance. As the car goes faster the car needs more power to accelerate. At one point (around 140 MPH, 6100-6200 RPM in a 2000 5sp) the power delivered to the wheels is not enough to overcome the wind resistance and you hit, what is effectively, terminal velocity or drag induced top speed. If it were a vaccuum (and you made your car run in a vaccuum) then your argument would be true.

 

I saw this type of thing happen on the new Acura RSX. The 5 speed has a higher top end than the 6spd Type S.

 

I think the reason for a 6 speed is for highway, the other gears are close in ratio so that you can have power, perhaps plenty in all gears up to 5th. Therefore faster acceleration, and then when you want to cruise say at 75 you won't be doing 3500 RPM... (just an example don't quote me on that) The 6th gear let's you cruise and possibly save some gas. So I would say the 5th gear would have more power than the 6th gear. ie on the 6speed f-bodies, Camaro, Firebird, and not an f-body, Corvette. This is the same with the Viper! 6th gear has no power... just for gas savings and highway cruising. You'll actually loose speed on 6th gear. Has two overdrive gears, 5th and 6th, but because of the final drive ratio, the 5th is still lower gear than the 6th. That's how those big engines can also gat 28 mpg on the highway. Think about it.

Hey Bert, lets put it that way, the 6th gear used under normal condition will defenitely give you a better top speed as long as you shift your 5th gear all the way up, just do the homework and drive test a 6 speeds you'll reach me in my thoughs. As an example take a 2K1 5 speed, the 5th speed is an overdrive gear which mean that the wheel are turning faster than the engine itselfe, you will not reach a higher top speed with the 4 th gear right ! you will attain the top speed with the 5th gear, but on the other hand you will reach redline faster with the 4 th gear it is exactly the same with a 6 spd. It is all a question of logic here, it is like asking if a car would go faster in 2nd or 3rd gear, by asking a question you raise the answer.

At one point (around 140 MPH, 6100-6200 RPM in a 2000 5sp)


My car was only taching 6300 at 153MPH. Wonder if the 2k and 2k1 have different ratio's?

 

That's not possible. 5th on the 5 speed and 6th on the 6 speed are the same ratio. The 6 speed is only available on the Type S which has 40more HP. Couple 40 more horsies and the same ratio the more powerful 6 speed will go faster.

Stereodude

 

Nope, they're the same. Supposedly the 2000-2001 goes 140 at 5900RPM in 5th.

Stereodude

 

Negative on that one. You most likely can't pull 6th to top speed, but 5th in the 2k2 is basically the same gear as 5th in the 2k-2k1. The top speed of 5th (assuming the HP to get to the redline) is 157 for 2001 and 155 for the 2002. The 2002 has more HP, so it can get closer to the redline than the 2001. If you really want a nice read about it look at http://forums.maxima.org/showthread....threadid=68113 It seems the 2002 6 speed SE should be able to run about 152-155. The 2001 seemed to be good for about 143. So the 2002 is a faster car.

Hey Stereodude, your point is closing the gap and make a lot of sense.

cheers
