Top Speed

Crash

I would honestly question the speedometer then (especially if it's stock because the computer limits you to 155). I've done a lot of math on this (as seen in other threads) about how much power it takes to get to certain speeds based on aerodynamics, weight, rolling resistance, power, etc.

Take a GPS system with you next time to see how fast you're REALLY going, because I really don't think those speedos are that accurate beyond 100MPH.

My Honda VTX1300 is 10% too high, which also means that the odometer rolls 10% too fast, and my gas mileage is 10% better on paper.

My Honda Civic is the same way - there was a class action lawsuit over it, where I could have put in a claim - except it had to be on leases and we bought ours...


Having said that, I don't know what Nissan does - if it's something where all the japan cars are like that or not.

the european Zs are limited to 155mph. the ones in asia arent as they used to be 180km/h and now they're not.

i've done mine up to 260kmh @roughly 6k rpm. i guess more is possible but the oil temp was off the roof and i ran out of road.

You are right about physics and top speed. Some speedometers can be off and a GPS is the way to go.
