[W126 Coupe] Differential ratios.

[Axel Wulff]

Mark,
 
Yes, the standard differential ratio favors top speed and cruising at low rpm's over quick acceleration.
 
Depending on how your cars were equipped in Australia, you'll have either the US very low 2.47, or the somewhat more aggressive European ratio at 2.65.
 
There are a wide range of differentials available for our cars, from a relatively mild upgrade that I use of 2.82 to a head-snapping 3.46.
 
The bad news is that your Series 2 car cannot use the differentials from the Series 1 cars ('79 - '85) because the subframes are different.
 
Good luck on your hunt. If you get really lucky, you'll find one of the Gleason-Torsen locking differentials that AMG used.Regards, Axel J. Wulff610-731-5453 Cellular610-572-4611 Home

Greetings list!
I always enjoy the threads of conversation on this site.
Almost everything about our SEC’s I love – the builders and designers were given the funds to do what they wanted seemingly without restraint – so rare in automotive reality today by a big producer. Something about owning the best car at that time in the world…
Thoughts, ideas give us all additional enjoyment from our cars that we all have in common.
Cultural boundaries are bridged in taking interest with the way other owners see these machines.
One of the differences that our SEC global community of SEC owners has is where we get to use these wonderful cars.
Just a quick picture of what the downunder drivers have.
It’s a big place with tough road regulations, we have speed cameras, aerial surveillance, mobile radars, red light cameras and a police/community culture that will fine you a $100 for exceeding the speed regulation speed by as little as 3kmh. I have little doubt that that the Australian road safety mentality is a positive plan as our fatalities and injuries are reflected in the statistics.
I have always been very hesitant about changing anything on my car just because of a personal interest in keeping things as they were planned – although reading comments and ideas from Dick and Satish has me thinking of buying a second car to have some different fun with.
The Australian delivered machine comes with the tall differential ratio – a couple of months ago a had a rush of blood and booted the car to 240kmh – silent and effortless, man that was way fun! I backed off before she was finished so I will never know where it would have ended.
Hey Jonathan, I want a shorter differencial – a bolt on solution to use some of that grunt around town – hanging up my low flying goggles.
You will know what can be bolted on without too much drama and what steps would have to be taken to adjust the speed gauge to read true.
Can you put together a post package to fit?
 
Best regards to all!
