4.11 ring and pinion

[koullis]

hi, i was just wondering what the gear ratio will be like when i put the 4.11 ring and pinion in my hellical lsd which now is 3.69 (i think)
its a spec s and now i am dong 100kmh@3000rpm in 5th. how will it be after the ring and pinion?

btw, very helpfull site.

You'll be doing 100 divided by 4.11, times 3.69 = about 90km/h @ 3000 rpm.

And you'll do about 3340rpm @ 100 km/h
