diff ratios
if youve got a 4.1 diff doing 100mph what will a 3.54 do at same revs

What are they currently?? Depends on the width as the profile is a percentage of width. I assume you have an english axle?
205/60/13's would give you a little over 185/60/13's but i really wouldnt bother with 14's to be honest - not the greatest selection
of tyres available

Andrew, I take it this is for your diesel locost project, in which case I'd go for a much lower ratio - I've got a diff from a BMW 330d
which is (iirc) 2.88:1 (assuming of course that you are using a half decent diesel)

Sorry to jump in, does anyone know if there is an easy way to tell what diff you have fitted? I have a mk2 escort live rear axle and other than
rolling the chassis and counting how many prop rotations there are to one rear wheel rotation is there a simple tell? Cheers
