Hi guys,
I know someone who actually has EFI on his (1700cc) Vmax. I do not know the
details about what parts he used, but I try to find out asap!

The electronics that I am looking at can be found at http://www.sdsefi.com.
I would consider the fuel only system "D" as the new digital filtering
should enable to us to use a tach or coil feed rather than having to make
and use a cam or crank sensor. A while back both I and the firm was
concerned about the quality of the Max's tach signal and how it would work
with their EM-2 system but they have made some improvements in their own
electronics (EM-3). With the Max's stock electronics it is my thought that
we can likely get the injectors to fire within a degree of optimum which
should be okay for our needs. This system does not sequential fire. The
thought is that the injector pulse width needed at high power settings on
engines like the Max is longer than the intake valve open period anyway.
I think either a single throttle body on a plenum with individual runners
per port or a smaller individual throttle bodies directly mounted on a
runner per port would work. Individual might give a little faster throttle
reponse and of course look trick...the stock manifolds could be adapted with
the right throttle body. As I suggested before I might look for a some junk
38 mm carbs just to butcher them for their bores and throttle plates.
According to my calc's, with an 85% duty cycle we would need injectors that
could flow at least 200cc min ... the Bosch 235's would probably be okay.
hey...maybe with the combined talent on the list we can make this thing
happen!
cheers, Terry
