Late 5sp gear ratios - 24/07/2007 16:42

Does anyone have the full gear ratios for the late 5 speed boxes including final drive?

I believe the 6 sp have a different final drive.

Cheers

Not sure if the online version of the manual is working any longer, my link is broken. But they are all in there. i'm sure someone will post them up but if not I'll get you them when I get home from work.

Does 3.111 (18/56) sound about right? (called crown wheel & pinion reduction). These figures are for a 5 speed box but if they changed later on I am not sure which year these ratios came from.

Working out how high you need to set the limiter for 200mph John? \:D

chewed up my 6speeder so am using a 5speeder for TOTB. 8000rpm limiter means I'm still north of 190mph in 5th.

It won't matter having a 5 speed over 1 mile which is probably a good thing! I reckon anything 170mph+ will be an awesome achievement but getting close to 200mph in a coupé is a little scary
