Sierra Cosworth 4x4 on snow
There are many who say I do not use the car, so I decided to skid a little in the snow. 
Summer tires and snow = very slippery! Therefore, I do not dare to drive so fast.

Many thanks guys! 
Well yes, with original open diff in front and with not that much speed it behaves like a RWD in many situations. But if you look at 4:55 in the vid, you see wide angle and little more throttle, you can se the funny with 4x4

I am actually still wondering how the handling would change if you fit a LSD to the front. In my case it would be for dry tarmac handling and not snow though. I have the feeling with the open front diff it understeers on corner exit when you apply the throttle.

Haven't you broken any diffs, driveshafts or gearboxes yet?

HahaI got a Oppliger Semu-Cut gearkit and Quaife rear diff, lovley upgrade! A Quaife front diff would be fun to test.
The rear Quaife diff is wonderful that is behaves like a RWD but the car itself behaves like a 4x4 when you got some speed.

All those movies are making me want to drive mine again. But still need to wait till the winter is over...
@Marco, when watching your video I also came across this one:
That's already doing quite well. I think at the time yours was about the same spec as mine is now. Did it reach the rev limiter in 5th, or was it limited by power? I would expect it to go a bit faster with 350 bhp.
I guess now with RWD and the T38 it's again much faster than this.

@ Marc It was limited at that time due too high charge temps as it had the standard IC and it was 30C outside, but i did another attempt later with a 500IC and cooler temps and reached the rev limiter in 5th doing 272 km/h on the GPS which surprised a E36 M3

272 km/hour, that's nice! 
I always wondered how fast a stage 3 cossie would go. With longer gearing it might have even gone a bit faster.
BTW, do you know what the rev limiter was set at? I believe mine is at 7200 rpm on the MSD chip. With 215/40 R17 tyres (don't know what you had) it should do 273 km/hr at the limiter in 5th. With the 5th gear from a MT75 diesel (0.76 ratio) it would be limited to 298 km/hr, assuming it would have enough power to pull that of course.
