CBY and co,
I have the handbook for my 89 Plus Four in front of me and note that there is not a lot of difference between then and now.
Gear ratios: 1st.3.32
2nd.2.09
3rd.1.39
4th.1.00
5th.0.79
@4500 Omex
Mph quoted per 1000rpm 1st.5.82 26.19 mph
2nd.9.23 41.535 mph - 54mph
3rd.13.90 62.550 mph - 80mph
4th.19.31 86.895 mph - 100mph
5th.24.41 109.845 mph
Final drive ratio. 3.73:1
Ibs/ft torque @ 4500rpm. 131
I don't yet know what my mph per 1000 is now after the Omex work or whether the gear ratios match, although something doesn't add up. Speeds in gears post Omex to the right. i.e the ones I have so far. I'll update when I know more. Fascinating stuff. p.s I can't make my columns straight!
