Ribcase Ratio's

Got to wondering what the rib case transmission ratio's were and since I'm too lazy to look it up thought I'd ask here. I'm sure I have the info somewhere????

Just curious.

Kurt,

There isn't a single answer to that since there are a couple different gear sets. See this link:

https://gerardsgarage.com/Garage/Tech/TransPartsIndex.htm

At some point, I'll have to look up the different ratios and add them to this page. The ratios will be in the different shop manuals specification section.
 
Thanks Gerard, I didn't realize there was so much complexity to it all. I do remember reading there was a difference between the Mk3 and Mk4 ribcase ratio. Couldn't find the info in Bentley's but it's really not all that important. The Lotus group has a system for comparing transmission ratio's and that got me thinking.

Glad I could be of help... :cheers:
 
Well, just to give a bit more info the formula compares different transmission's to an ideal by what the differences are between gears. I believe the ribcase has pretty good steps between the gears. I have driven some 4 and 5 speed's that had lousey spacing between gear's.

Straight cut close ratio...very noisy, but a good 'racer'.
