I tried searching and didnt come up with anything, but I was just wondering if anybody had a list or chart that lists what speed (mph) each gear tops out at?

I just finished this page last night. Check it out. It is programmed with 350z's ratios already!!

 

[thrlskr]

You'll have to select 6600 in the RPM field and select the gear your interested and select calculate speed. Cool Huh? Btw if it doesn't work let me know; you're my first visitor.

nice man, thanks
worked great :thumbsup:

Cool link!

 

[thrlskr]

Thanks guys! I'm working on few more calculators as well; check back later!

Does that take wind resistance into effect or just based on the gear ratio and RPM? If it's the latter, then the 7,200 increased rev limit raises the top speed to close to 200MPH!!!

 

[hazade]

even though the gearing allows for that, i think the Z tops out before that

 

[thrlskr]

No drag...just gearing; sorry.

 

[nismokid]

Here's a graph of the Speed v. RPMs based on that calculator.

Nismo, I have to ask. What do you do? Or what are you studying?

 

[nismokid]

Well, gear ratios, rpm, and velocity are all linear when graphed. Using the calculator thrlskr made, I marked down the speed while redlining (6,600 on this calculator, which is factory) and connected it to the origin. You connect a horizontal line from the redline of a gear to the line of the next highest gear. That's where the RPMs would be if you shift at redline. You see if you downshift while redlining, it won't be on the graph. That's bad, lol.

 

[smoothz]

So why the velocity in kmh?

 

[nismokid]

Here's a comparison of the Bugatti Veyron (left) and 350Z (right). I'm almost 100% sure the Bugatti's diagram takes air resistance into account (they really want 250mph real life speeds) while the 350Z is without air resistance. So the two graphs should be further apart.

P.S. I made the 350Z graph based on the way Bugatti made theirs from their site.

:lol: Bugatti = faster, because of 7th gear. I wonder what acceleration is like for the Bugatti. 62mph in first gear! Wow!

Not that you could find one, but if you changed your Z's Final Drive to 2.14 then you'd redline at 62mph in first gear too AND your topspeed would be 297!!!! It would just take along time...as in never!

0-60mph is suppose to be upper 2s and low 3s. Incredibly fast in other words, lol!

From reading this graph I am gathering that the top speed on a stock final drive is 180mph. I have hit 159mph on my Z, and was enthusiastically awaiting a reflash to uncap my top speed to a rumored 190mph. Is this not possible? Btw, 180mph would still be badass
