Only an object with zero mass (i.e. a photon) can travel at the speed of light. And so far, there is no evidence that any object regardless of mass can travel faster than the speed of light. So infinite speed is a theoretical impossibility, at least according to what scientists think.

Ha yes you are true!
I was trying to sort of keep it in the realm of the car. And yeah, by infinity, I mean the speed limit of the universe: speed of light. I completely agree with you, I was just trying to keep this applicable to the Z, which, as badass as it is, won't get to the speed of light. Haha!

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.

Manual you can get to ~67 mph in second.

The 7at tops out around 54mph in second.

Its been discussed before at length.

RandyD · 11-19-2012, 09:44 AM

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

Mt Tam I am · 11-19-2012, 11:27 AM

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.

Where'd you get that final drive from?

m4a1mustang · 12-11-2012, 11:29 AM

It's possible but the stock body is really slick. I don't think you'll do much better without a strong tail wind.
