Top Speed

[Clutch]

What?s the top speed of 1, 2, 3, 4 and 5 gear of a F10WR gearbox at 6800rpm?

[Snowface]

depends how big your wheels are and what size tyres u have on them.

and what final drive u got.

[Clutch]

The wheels are 195/45 r14 and the final ratio is standart of a f10wr

[Paul]

AFAIK f10wr come with more than one final drive

[Jack]

4.18 or 3.94

[Snowface]

or 3.74.


3.74 in 5th would be 140mph
4.18 in 5th would be 125mph

[Stuart]

no :p

[Aragorn]

i had an imporved version of your original spreadsheet kicking around

it gave speed in gear at rpm rather than rpms at set speeds which makes it a bit more user friendly

and it also produces graphs

its here:

http://kevingalloway.myby.co.uk/gearbox%20graph.xls

2x tabs at the bottom let u choose CR or WR clusters, then u modify the tires and final drive to suit

i provide a list of available vaux final drives for you too

[Stuart]

problem being no accounting for dynamic wheel radius ;)

[Aragorn]

so have you modified mine to account for that?

or modified your original one?

what kinda % out is static -> dynamic measurements?

[Stuart]

it was created from scrath as i lost my original one thats being touted on here :p


the % varies ;)

[Aragorn]

oi its not all your work!

i took it and rewrote the formulas to display the opposite way round added the graphs and other friendly data and made things easy for the user to fiddle with

anyway i look forward to seeing your latest version
