[W126 Coupe] Help! : diff ratio's

[Divov]

Thanks for that tip Barry.
I take it that it is also the diff with the big square rubber mounting situated aft?
Its good to know that such a ratio exists but down South, SL spares are pretty thin on the ground.
Would the 450SL have this type of diff or is it only from the 500SL?
The 450SL is an absolute dog but a friend had a late 500SL (same shape as the 450) and though it was years ago, 
I recall the acceleration was reasonably impressive from the passenger seat.
Do you know if your 3.07 diff is an LS diff?

  Dawid,

  The 500 is really a bit of a slouch off the line. The 560 is a rocket in comparison.

  My 500 (at highveld altitude) does about 230 kph in 3rd (at 6000rpm) but max'es out at only 240 in top. At 240 it is only revving around 4200...

  The 500 mill is free revving and goes to red line willingly (except in 4th!)

  That 2.24 diff ratio on the 500 really really makes it an old mans car. 160 kph @ 2900! - its hardly working up a sweat.

  Your 560 does about 7 sec  0 - 100 kph & is way, way faster. I think partly from more beans & partly from 

  better ratios.

  Clearly the 560 was aimed at being more sporty - and certainly is.

  I have only 170KW vs your 220KW. That's a serious difference... 170 KW moving 1600kg aint no ball of fire.

  Alec, it seems like you would benefit from an even lower rear end (higher numerically). You mentioned that you were going to try to find a 2.65, I believe, to replace your 2.24? Isn't there a 3.07 available and wouldn't that be even better?

   

  I know Barry Corno's 380SEC really improved in acceleration with the change to the 3.07.

      Steve is right on the improvement. I did loose 1 ½ mile per gallon, but have picked it back up

  With cats removed.  It is a cheep fix for a 380 PIG. On the pre 86's it is a bolt right in Diff from

  Any pre 80 SL or SEL.
