I.E is this effected by gearbox and diff ratio? Unfortunately my graph doesn't have this engine rpm displace. At first glance it looks like it would work... Yeah it’s affected by diff, gearbox ratio and slip. Even locked up the ZF has 2% slip. So it’s not accurate like you can calculate with a manual in 1:1 ratio. Find ZF graphs of the same gear (Ie 4th)and then divide the derived rpm by axle rpm and then average this for different rpm values above 4000rpm. Use this ratio for your own car. so say your axle rpm is 1400 and your conversion ratio from other graphs is 3.1 then the engine rpm is approximately 1400x3.1=4340 Edited 04/07/18 11:56 AM by IH8TOADS 2 Link to comment Share on other sites More sharing options...

Cause it will be the same as yours. Some diff ratio, same gearbox. Same 4th gear run. Link to comment Share on other sites More sharing options...

Ie axle rpm x diff ratio = engine rpm. There is no slip with a manual so it’s easy as and precise. Link to comment Share on other sites More sharing options...

Was there with a couple of the usual suspects drinking coffee and looking at cars. The Army Tank got to hang out with its great grandad and its annoying American cousin.
