[s-cars] V8 Diff swap

[Mark Strangways]

I think it was likely the drop of the clutch at 5500 rpm that did it  :-)

Nah, well maybe..
I will let Dave answer it, I just thought I'd add my useless info.

  Do you think the 440lb-ft. of torque caused the failure?

  I wonder what is the intended design limit of the Torsen diff?

  Have you switched to a heavier-duty clutch-type diff? I like the Eaton electromagnetic diff that 
  is advertised in Mustang/Camaro circles- I wonder if that one can be adapted to an Audi application
  if you have a custom housing.

    SAE corrected figures were 440ish hp, and 440ish torque at the wheels.  Because of the debate on correction factors, I ran it at a dragstrip at a lower altitude than Denver (2800ft)... based on the trap speed, the hp calculater indicated 455hp at the wheels. 

    I think it's safe to say "over 400 at the wheels."

    Dave-
    How much hp/torque are you running that killed your Torsen?

Bolt in for the UrS. I have heard that in big HP Audis, the Torsen can fail,can anyone confirm this?Aren't you running a BIG turbo, Mark?Taka
