I wonder if one could fit a pot from a 930 to the SC distributor to get "boost retard" in place of vac retard.

I suspect one would have to use the inside or Vac Retard side of the 930 pot to do this. Then just set timing like on a 930 at 25 deg at rpm and when boost come up it would retard to about 19 deg.

I wonder if there is a correlation between the direction a Porsche dist rotates and if it has vac-advance (2.7RS and 3.0 Turbo?), or vac retard (SC and 3.3 Turbo?).
