km/h per 1000rpm

Anyone has the gear rations for the 40th Anniversary?

specifically how many km/h per 1,000rpm for each gear ?

Last night I hit 263km/h with 6th gear, tach reading arnd 6,100rpm. Wondering what was the actual speed ...

Thanks

You will also have to consider your tire size to accurate calculation.

[mat911]

rear tires are 285/30 18 (standard), that means I can you the figures you posted to determine actual speed (km/h per 1,000rpm) ?

Are you sure 1st gear gives only 8km/h per 1,000rpm ? That means at redline (7,300) still can not reach 60km/h...

I am sure 1st gear tops at around 65 km/h

Your first gear limit with those tires at 7300 is 40.89 mph or 65.81 kph. Third gear at 6000 rpm will give you a speed of 84.46 mph or 135.93 kph. At 4000 rpm in thirid, your speed is 56.31 mph or 90.62 kph.

OR:

At 7300 rpm, maximum speed is as follows (MPH):

1st - 40.89

2nd - 71

3rd - 107.76

4th - 128.03

5th - 153.14

6th - 185.95

and if you want to have some fun....reverse maximum speed would be - 44 mph.
