My limited Physics knowledge says that at a certain point, the car will not be able to accellerate any further as the wind resistance will be too great, so it will never see the 7500 redline in 6th. It will just sit on a lower rpm and be unable to push through the wind given it's known HP output.

More power and torque will change this.


I've been saying this all along on other threads. The only problem with using 5th is running into the speed limit of the rollers on the dyno. Some dyno's only support 200km/h, so using 4th is the only option to keep the speed down. (shoud only vary by a few kW anyway.)

my 2c

What's interesting is that using 4th, unless compensated for in some way, the 7AT will show higher torque numbers (and therefore higher HP) due to the reduced ratio in the rear end and 4th gear.

Hmm...interesting, but, not that it matters much. Comparative gains is what I'm interested in, which before and after dyno runs is good enough. :)

0-60 by 2nd Gear?
 

Is this possible with either transmission? I'm asking about stock of course.

Thanks!

For the manual tranny yes, not sure about the auto

The auto takes you to somewhere between 55 & 57. However, once you hit it into 3rd you blow right by 60 almost instantaneously and are threatening 100 before you know it.

I can get to 60+ mph in 2nd.

Manual you can get to ~67 mph in second.

The 7at tops out around 54mph in second.

Its been discussed before at length.

:iagree:

by the time i notice the shift and look down its at 80 :)

Gear 6MT/6MT Sport
1st 41mph
2nd 68mph About this as I see it as 70 ish as it goes by
3rd 97mph
4th 124mph This is about where I got to as the rev limiter flashed.
5th 157mph Don't know
6th 198mph Doubt, but don't know

This chart is close enough for government work, in my experience.

:tup:

Zero to 37ish...
 

Trans: Stock FS6R31A
final drive gear ratio: 4.363
Tires: 295/30R19
Rev limit: Stock 7,400 RPM / Reflash 8,000 RPM
Top Speed per gear in mph: stock (reflashed)

1) 35 (37)
2) 56 (61)
3) 81 (87)
4) 103 (112)
5) 131 (142)
6) wind resistance, speed unknown

Where'd you get that final drive from?

155mph and the fastest I ever heard of a Z going without the limiter is 168mph. I'm Seriously guessing with this part but, the right body kit it might hit 170-172mph without a limiter?
