153mph in 6th at 9200. Assuming it's an AP1 stock trans with stock AP1 tire size.

153mph - with stock 4.1 gear ratio

That means with 5.5 (does it exists? I heard only about 4.77 and 4.9) top speed will be lower than 120mph, maybe even 110.

Sorry you are right. 4.88, forgot 5th gear isn't 1:1.

Ok I worked it out...

1st 63kph
2nd 96kph
3rd 133kph
4th 170kph
5th 203kph
6th 237kph

Based on a 4.88 diff and 235/45/17 tyre and 9,200rpm limit and AP1 trans.
