Driving a Z question

Someone needs to do the calculation. What speed would you be traveling in 6th gear at 7500 rpm?

uhh.... limp mode does happen with the manual.

OK,

ROUGH calculation here...

.794 6th gear ratio, 3.692 final drive ratio (6MT), 275/35/19 tire, 7500 rpm... about 200 MPH.

That sounds a bit high (final speed, that is). I went 160 at 7100rpms. But I have 20" rims (speedo is approx. ten percent off).

Sweet. Time to go to the texas mile!

With a 26.6" tall tire, .794 6th gear ratio, and a 3.692 final drive ratio the theoretical top speed is roughly 201 mph and change.

In 5th gear (1:1) it drops to ~161 mph.

Just make sure you call ahead and tell them to place the track inside a vacuum.

Which is why I said theoretical top speed. These are just gearing calculations. Obviously a stock Z can't get anywhere near theoretical top speed.

I actually took the time a while back to do an accurate calculation of the top speed of the 370Z. I think it was something like 168mph or so.

I actually took the time to figure it out for myself.

What did you come up with and how?

shadoquad · 10-12-2011, 11:02 AM

Why don't we see if we can find a German Z owner and get him to disable the car's governor and go find an Autobahn?
