3:45 VS 4:11

Recommended Posts

hEY GUYS ,

 

Im wanting a bit more launch power in my el xr8 ( 4 speed auto ), and it has the  factory diff with the ratio 3:45. My question is if I change it to 4:11 ratio...can it mount in the original diff or is something more needed?

A shop thats good with diffs will be able to change to 4.11 gears easily enough, I have a XG/XH LSD that was built as XY drum brake with 4.11 gears was told was built by Geelong diff services. That said a hi stall convertor would possibly be a good idea, when you take off will flash up to xxxxrpm & help with take off, stock would be like 1800-2000rpm

Cheers ! I'll check on the high stall requirements.......

 

Though, by changing the diff gears.........will I have any ECU issues? ( erratic gear changes ) or some other electrical issue?
