Compression test on EL

[Franco Cozzo]

While I'm at the conversion we're thinking about changing to either 3.9s or 4.11s in the diff, what would I be turning at on 100/110km/h?

At the moment I'm doing 2000 RPM in 4th with the auto with 15" wheels and 205/65 tyres, 3.45 in the rear. What would I be doing with the 3.9 or 4.11?

Also its going to knock my speedo out by a huge margin, what can I buy to correct that?

If you know the ratios just punch them in here: http://www.my330i.com/gears.php

These guys might have a module for the speedo: http://www.shiftkits.com.au/

Thanks guys, assuming .73 for 5th gear, 4.11 puts me at 2500 RPM at 100km/h, I mainly do highway driving, do you think that is a bit high? Its less than what my Fiesta does at 100km.h (3000 RPM) but my Falcon has full exhaust done, so reckon it might be a bit loud?
