I've not actually driven a torsen diff car but all the contemporary roadtesters say there is. Mine has the 50/50 split and original big turbo and it can be driven at scary speeds. Wet or dry road, doesn't make much difference, Brake late and not too much, aim for a very early apex and floor it well before the apex. If you get it right the turbo spools up at the apex and launches you out of the corner. Hugely addictive and great for scaring people who have never been in one...
