Whats the top mph in each gear? Searched
I new that 1st went up to around 40 mph so I thought
1st - 40mph
2nd- 80mph
3rd- 110mph
but when I tried,
1st - 40mph
2nd- 60mph
3rd- 90mph
Is this right?

yeah, approximately.
1st 3.230 / (8400 rpm) 39 mph
2nd 2.105 / (8400 rpm) 60 mph
3rd 1.458 / (8400 rpm) 87 mph
4th 1.107 / (8400 rpm) 115 mph
5th 0.848 / (8000 rpm) 143 mph

The numbers are 40.3, 61.9, 89.3, 117.6, and 153.6 at 8400 RPM, according to the gear ratio spreadsheet. I don't know if the differences are due to rounding or what (other than in fifth, which is at redline and may not be achievable due to aerodynamic drag)...

Math challenged, huh?
Take each number above, divide by 8400 and then multiply by 9500 and you'll get your answer.

I can't open the spreadsheet (through no fault of the spreadsheet), but:
Was it calculated to fuel cutoff or 8400 redline? And, did it take into account the actual diameter of the OEM tires (versus the theoretical height of a 195/55 R15 tire)?
I think those numbers are from the owners manual, and may have been converted from km/h, but they seem consistently different.

The spreadsheet gives speeds for RPM readings at 100 RPM intervals, all the way up to 9500 RPM. The figures I quoted are for 8400 RPM.
The spreadsheet uses an outer diameter of 22.8 inches for the tires. I'm not sure where that number comes from. If you calculate the diameter of a 195/55-15 tire, it comes out 23.44 inches. The actual diameter that should be used in RPM vs speed calculations should reduce the diameter to account for the deflection of the tire by the pavement, but I'm not sure how much that would be, or whether that accounts for their 22.8 figure.
