Top Speed for 1st gear

Can someone tell me what the max speed is for first gear on a 07 C6 MN6 Z51? Are the max speeds for each gear listed anywhere?
Just curious.

Here is the easiest way to calculate top speed of each gear. Drive it to around 3250RPM, look at your speedo and multiply that speed by two. For example, if you drive your MN6 Z51 in 1st gear at 3250 RPM your speed should be around 25MPH.. So at 6500RPM your top speed in 1st should be around 50MPH. This works on every gear on manual cars up to car's top speed granted your clutch is not slipping

Just input the correct data for your particular car and it'll spit out a nice chart
with all the details of all the gears.

You mean MZ6... not MN6. Technically speaking, the Z51 gets the MZ6 which has different gear ratios than the MN6 in the base car. Just mentioning it to avoid any confusion.

Here are all the ratios... now you just need to do the calculations for rpm.

Column 1: A6 (automatic)
Column 2: MN6 (manual)
Column 3: MZ6 (Z51 manual)

Gear ratios
1st gear-----4.02---2.66---2.97
2nd gear----2.36---1.78---2.07
3rd gear----1.53---1.30---1.43
4th gear----1.15---1.00---1.00
5th gear----0.85---0.74---0.71
6th gear----0.67---0.50---0.57
Reverse-----3.06---2.90---3.28
Rear axle--2.56---3.42---3.42

Andy where in the Central Valley are you located? I am around the Fresno area. We have the same color car. I have an 07 MN6 Z51, but mine is lighter with the 1LT package
