 Interesting read from Ben and Scott J / Cody, etc...........
Huw, the distributor "slop" was a factor in the 3B when used with the incorrect WIDTH rotor on highly boosted engines.
The Audifans archives should have the stories from years past of the wider MC rotor used in place of the narrower 3B to a catastrophic engine demise.

Spark jumping to another rotor plug lead was the issue, slop influenced IIRC.

I'll buy that.  And I also understand that on these turbo engines Audi 
wanted really precise control of ignition so they could push the advance 
safely.
