: For all you turbo slant six owners out there,
: how did you deal with getting the spark

: Or is such a thing unnecessary? besides
: recurving, how much work do you have to put
: into modifyin the distributor?

:
: That difficult, eh? Guess I might need to get
: an MSD6 Boost Timing Master, or maybe even
: one of the Electromotive crank-triggered
: ignitions. I'd hoped I could get it to
: retard the timing mechanically.

: Wow,
: You just hit the reason I do not run a turbo
: SL6 as an "everyday car", I could
: never get the advance curve
: "mapped-out" right.
: Best I ever got was a mechanical advance system
: and an MSD retard, no vacuum advance.
: In concept you may be able to find a place
: "up-stream" of the turbo and
: pick-up some kind of vacuum advance signel
: there.
: Thruth is that it is best to go to an EFI
: set-up with the sensors and a computer
: "map" to follow the needed turbo
: curve. This is pretty high tech stuff but
: the technolgy is here, you just need to
: learn it!
: DD

: I am not even sure of this, but could you not
: drill a hole on the back side of the vacumn
: advance module, run a line from the boost
: side of the turbo to it to provide a make
: shift "BOOST REFERENCED" advance?
: Then just work in the mechanical side and
: limit the total.
